The sporty elegance of the 2011 Audi A3 models

The sporty elegance of

the 2011 Audi A3 models

In 2007 Audi introduced a new 1.4 L TFSI engine for the second-generation A3 as well as the new "e" model which is basically the equivalent of the Volkswagen's Blue Motion, this last version was also designed to be a more ecological vehicle by reducing the CO2 emissions. The five door version, dubbed the Sportback was introduced in 2004, it featured improved rear cabin space as well as a new front grille. The second-generation A3: As a continuation of the first generation A3, a second-generation vehicle was created, this four-cylinder version was first featured at the Geneva motor show back in 2003, it was originally launched as a three door hatchback but later on it also became available as a two door convertible and also as a five door estate. This version was in production until 2003.
Later on in 1999, major improvements were made to this version, a more powerful 1.8 Turbo which was based on the A3 was introduced however, Audi was pretty much forced to comply with the consumers demand which is why they came up with a five door hatchback but the company originally did not intend to produce. In addition after the A4, the A3 model was also known for being the first vehicle in the Audi line to use five valves per cylinder. In order to provide a more sporty image when compared to the golf model the first generation A3 featured a three door hatchback, it also had a 4 Wheel Drive and the engine was transversely mounted and it had a four cylinder configuration. The first-generation A3: The production of this car model started back in 1996, logically it was first introduced to the European market.
Other versions based on this generation of vehicle are the Audi TT, the Volkswagen golf, Touran, etc. The two versions of the Audi A3 share common characteristics found in the Volkswagen A-class, this is due to the fact that both versions were based on the Volkswagen model. This car manufactured by the German automaker Audi falls within the category of a luxury vehicle and can also be classified as a family car, because of its popularity several improvements were made to the first version which opened the doors to the creation of the second version of the Audi A3.

2011 Audi A3 Sportback profilation of this cars :

Refined style, agile driving fun and elaborate technology - the Audi A3, the A3 Sportback, the A3 Cabriolet and the S3 are the sporty models in the compact segment. Audi now displays its premium character even more explicitly through new attentive details on both the exterior and the interior.
The sporty elegance of the Audi A3 models is already perfectly expressed in their design; their harmonious styling now acquires a host of new, exclusive touches. The single-frame grille element and the trims on the B-posts are painted in high-gloss black, the lower air inlets have chrome struts, the exterior mirrors are aerodynamically optimized and there are chrome strips in the door handles (except on the S3). At the rear, all A3 versions have a new diffuser insert with eye-catching separating edge, and the rear lights are tinted on the three-door version.
The paint finishes Volcano Red, Dakota Gray, Amethyst Gray and Scuba Blue are also new. There is a new wheel design for the sporty Ambition equipment line. The wheels available as options also extend the range. There is now a high-gloss 17-inch wheel in ten-spoke design, and two other new wheels are also available from quattro GmbH: a 17-inch aluminum wheel in a five twin-spoke design and an 18-inch wheel in five-arm rotor design.

Refined style: the interior

The interior of the Audi A3 models is likewise even more exclusive. The key features are dials with a gray background, a flat-bottomed leather sports steering wheel complete with trim ring, a new selector lever for the S tronic, black rings on the air vents and a high-gloss trim for the optional navigation system plus. There are gleaming aluminum-look trim inserts on the center console, mirror adjuster switch and window lifter buttons.

Powerful and efficient: the drive train

The engine range for the Audi A3 and A3 Sportback is very extensive - it comprises nine power units, five of them gasoline and four diesel. All are cutting-edge turbocharged four-cylinder direct-injection units badged as TFSI and TDI. They encapsulate all the strengths of Audi engine technology - performance, refinement, high torque and efficiency. Five of the nine engines also feature in the new A3 Cabriolet, with the most powerful version reserved for the dynamic S3 and S3 Sportback - the 2.0 TFSI developing 195 kW (265 hp).
The entry-level gasoline version is the 1.2 TFSI; it is a prime example of the merits of Audi's downsizing strategy - prioritizing supercharging ahead of displacement. This four-cylinder power unit develops an ample 77 kW (105 hp) from a swept volume of 1,197 cm3 and generates a hefty 175 Nm of torque (129.07 lb-ft), yet averages just 5.5 liters of fuel per 100 km (42.77 US mpg). The most powerful spark ignition engine for the Audi A3 and A3 Sportback is the 2.0 TFSI with an output of 147 kW (200 hp). It is trumped only by the 2.0 TFSI on 195 kW (265 hp), which is reserved exclusively for the S3 versions.
The TDI range extends from the 1.6 TDI developing 66 kW (90 hp) to the 2.0 TDI, with an output of 125 kW (170 hp). The most efficient engine version in the car line - and one of the most efficient compact models on the market - is the Audi A3 1.6 TDI developing 77 kW (105 hp) and 250 Nm (184.39 lb-ft) of torque. It is available in three different versions, the most economical of which is an Audi A3 three-door version averaging 3.8 liters of fuel per 100 km (61.90 US mpg). In-detail modifications to the body and running gear contribute towards this excellent figure, which equates to CO2 emissions of just 99 grams per km (159.33 g/mile).
Audi fits a start-stop system including energy recovery on five engines in the three-door A3 and the Sportback - the 1.2 TFSI, the 1.4 TFSI, the 1.6 TDI developing 77 kW (105 hp), and the two 2.0 TDI versions with outputs of 103 kW and 125 kW (140 hp and 170 hp). In a new departure for compact cars, it is irrelevant whether a manual transmission or the S tronic dual-clutch transmission is fitted. It proves a big advantage in city traffic - it deactivates the engine while stationary and restarts it when the clutch is pressed or, on S tronic versions, the brake pedal released.
An energy recovery system that captures the energy released during braking is a standard feature of the 1.6 TDI with 66 kW (90 hp) engine and the 1.8 TFSI.
The range of transmission technologies is equally very diverse. Most engines in the Audi A3 car line come with six-speed manual transmission as standard; Audi can also supply the lightning-fast, extremely convenient S tronic in conjunction with many of its engines. It is fitted as standard with steering wheel shift paddles on the Ambition equipment line and S3. Depending on engine version, the dual-clutch transmission has six or seven speeds. The seven-speed version operates with dry clutches; the absence of an oil supply improves the transmission's efficiency yet further.
The option of power transmission to all four wheels likewise underscores the exceptional position that the Audi A3 enjoys in the premium compact class. Audi supplies quattro permanent all-wheel drive for four engine versions. The Cabriolet is the exception; on the other hand, quattro drive is standard on the S3 and S3 Sportback. Its electronic-control multi-plate clutch, mounted on the rear axle for a balanced weight distribution, apportions most of the engine's power to the front wheels in normal driving conditions. If need be, it diverts drive torque swiftly and adaptably to the rear wheels.

Smartly sporty: the running gear

The running gear of the Audi A3 car line combines a sporty character with superb safety and high comfort. Its precision and poise stem from technically elaborate solutions such as four-link rear suspension, which handles longitudinal and transverse forces independently, and the electromechanical power steering, which is as responsive as it is efficient.
On all versions with front-wheel drive, the ESP electronic stabilization program incorporates an electronic differential lock. When close to the limits of handling on bends, this intelligent software solution manages how the drive torque is distributed among the wheels by small, barely detectable brake applications. These suppress any understeering, improve traction and further enhance driving safety.
For the engines developing 103 kW (140 hp) and upwards, except on the Cabriolet, Audi supplies the adaptive damper control system Audi magnetic ride, which exploits the properties of an electromagnetic fluid. The dampers can be set for a comfortable or sporty characteristic. Within the parameters, the system adjusts the damping forces in milliseconds depending on the road conditions and the driver's style. The body sits 15 millimeters (0.59 in) lower with this system. There are also the options of conventional sports suspension and the supple S line sports suspension from quattro GmbH. The S3 comes complete with specially tuned 25 mm (0.98 in) lower S sports suspension.

Extensive: the equipment

The improved models in the Audi A3 family will be arriving at dealers in the early summer. Their extensive range of high-end options demonstrates their high technological caliber. These include the dynamic cornering light system adaptive light for the xenon plus headlamps, the high-beam assistant and the navigation system plus with MMI operating logic. It calculates routes particularly fast, has a higher resolution and features three-dimensional map graphics.
The parking assistant is another very attractive feature. When driving at slow speeds (up to 30 km/h, 18.64 miles) its ultrasound sensors scan the parking spaces parallel with the road; when it detects one that is large enough to reverse into, it then indicates this in the instrument cluster. All the driver need do is engage reverse and operate the accelerator, clutch and brakes - the car maneuvers independently and precisely into the space.

2011 Audi A7 Sportback profilation of this cars :

Emotion-packed design, sporty character and innovative technology: Audi is targeting a new market segment with the Audi A7 Sportback. The large five-door model with the dynamically accentuated rear end brings together the best of three worlds: the sporty elegance of a coupe, the comfort of a sedan and the practicality of a station wagon.
The Audi A7 Sportback is pure high-tech. Its body is very lightweight thanks to numerous aluminum components. The elegant interior shows a craftsman's level of workmanship. The four V6 engines combine refined power with groundbreaking efficiency. The 3.0 TDI with 150 kW (204 hp) and multitronic has CO2 emissions of just 139 grams per kilometer (223.70 g/mile). The sporty chassis comes with new solutions, such as electromechanical power steering. When it comes to assistance and infotainment systems, the luxury-class coupe exhibits all of the innovative power expected of Audi.
The five-door coupe from Audi combines supreme, long-distance comfort with a sporty character. The interior noise level is very low even at fast highway speeds, with the V6 engines providing refined acoustic feedback as their power unfolds.

Interior design

Air and light, sleek shapes and bright colors: The interior of the Audi A7 Sportback is an emotional space full of lightness and expanse. Its lines take up the powerful, sinewy sportiness of the exterior to demonstrate Audi's status as the leading brand for vehicle design.
The salient element is the "wrap-around" - a horizontal line encircling the entire cabin. It extends in a curve from the driver-side door sill across the instrument panel to the passenger-side door sill. The wrap-around embeds the driver and front-seat passenger into the interior. The exterior and interior form a harmonious design element. The frame of the door opener invokes the shape of the rear side window from the exterior.
The large arch integrates a low and slender instrument panel that slopes slightly downward toward the passengers. The application strip with its integrative dynamics is the salient element of the dashboard. Its face forms a wave oriented toward the driver, and even the dividing line between the upper and the lower segments is in the shape of an S. The center air vents follow this line and are shaped like a wing.
Audi's legendary attention to detail characterizes the entire interior of the Audi A7 Sportback, just as it does in the A8 luxury sedan. Materials are chosen with the utmost care; the uncompromising workmanship is on a craftsman's level.
The strongly driver-oriented cockpit comprises the instrument cluster, the air vents and the control elements. The aluminum finish highlights the rotary knobs. Both the shift gate and the start-stop button feature subtle red backlighting.
Audi will immediately be offering a wide range of upholsteries and decorative elements, including Milano and Valcona fine leathers, a leather/Alcantara combination and a leather package for the center console, the armrests in the doors and the door pull handles.
Audi offers inlays in a choice of two aluminum applications and two types of wood: natural brown fine grain ash and dark brown walnut. A veneer of layered oak will be available later. Audi has made significant advances in the technique of cutting veneers from a single block and uses painstakingly prepared and treated oak.

Controls and interior

The Audi A7 Sportback offers a full range of functions, yet its controls are simple and intuitive. The large, clearly marked dial instruments with their red needles and the display of the driver information system (DIS) are located under a flat cowl. They appear three-dimensional and extremely precise.
The optional driver information display - either 5 or 7 inches and white or in color depending on the version - bundles a lot of important information and settings in a logical menu structure and is controlled using the leather multifunction steering wheel. Another standard feature is the on-board computer with efficiency program. It provides tips for efficient shifting, includes a gear-change indicator and shows how individual systems affect fuel consumption.
The central on-board monitor, the standard version of which measures 6.5 inches and has a high-gloss black frame, is recessed into the center of the dashboard. It extends electrically upward in an elegant motion when the ignition is switched on. The instrument panel, which is inclined toward the driver, contains the control unit for the highly efficient deluxe air conditioning system and secondary switches for direct access to the most important functions. All other functions are offloaded to the MMI (Multimedia Interface) operating system located on the wide, asymmetrical tunnel, which forms a separate component with no connection to the center console.
The operating logic of the MMI is exemplary. The hard keys are used to jump directly to the main menus; the soft keys and the central rotary pushbutton are used to navigate within them.
The driver can jump to the menu overview at any time using a central menu button. The central rotary pushbutton is used to select the desired menus and functions. The main functions of the audio system make up one logical unit and are consolidated in the main control element. The electromechanical parking brake leaves a lot of room on the center tunnel for a comfortable, steplessly height-adjustable center armrest, a telephone and a large storage compartment.

Engines

The Audi A7 Sportback will hit the market with four direct-injection V6 engines: two gasoline units and two diesels. Ranging from 150 to 220 kW (204 to 300 hp), the engines propel the large five-door coupe smoothly and powerfully, with astonishing efficiency. The 3.0 TDI multitronic with front-wheel drive and 150 kW (204 hp) consumes on average just 5.3 liters of fuel per 100 km (44.38 US mpg), corresponding to CO2 emissions of just 139 g per km (223.70 g/mile). No competitor in this class can boast figures this low. All engines use Audi's innovative thermal management system, a recuperation system and a start-stop system.
Audi has thoroughly revised the two gasoline engines, the 2.8 FSI and the 3.0 TFSI, with respect to internal friction and thermal management. The engines quickly come up to operating temperature following a cold start. A separate heat exchanger is used to also bring the transmission up to temperature. The 2.8 FSI has an additional efficiency technology on board - the Audi valvelift system varies the stroke of the intake valves as needed. This enables the engine to breathe with significantly reduced throttle losses in many partial-load ranges, boosting torque and reducing fuel consumption.
The 2.8 FSI produces 150 kW (204 hp) and 280 Nm (206.52 lb-ft) of torque at 5,250 rpm. The torque is available from 3,000 to 5,000 rpm. Audi pairs this engine with the S tronic transmission and quattro all-wheel drive. The Audi A7 Sportback 2.8 FSI quattro sprints from zero to 100 km/h (62.14 mph) in 8.3 seconds and has a top speed of 235 km/h (146.02 mph). It consumes just 8.0 liters of fuel per 100 km (29.40 US mpg) on average, which corresponds to only 187 grams of CO2/km (300.95 g/mile).
With the top gasoline engine, the 3.0 TFSI, a supercharger compresses the intake air for improved efficiency and performance. The three-liter V6 produces 220 kW (300 hp) between 5,250 and 6,500 rpm, and delivers 440 Nm (324.53 lb-ft) of torque between 2,900 and 4,500 rpm. The supercharged engine, which in Europe is mated to the S tronic and the quattro powertrain, gives the five-door coupe the performance of a sports car.
The standard sprint takes just 5.6 seconds, and top speed is limited to 250 km/h (155.34 mph). Standard fuel consumption is just 8.2 liters per 100 km (28.68 US mpg), corresponding to 190 grams CO2 per km (305.78 g/mile).
The 3.0 TDI is available in two versions. The more powerful version of the big diesel, which has been completely redesigned, produces 180 kW (245 hp) between 4,000 and 4,500 rpm and 500 Nm (368.78 lb-ft) of torque between 1,400 and 3,250 rpm. The S tronic and quattro all-wheel drive are also standard here. Acceleration from 0 to 100 km/h (62.14 mph) takes 6.5 seconds and top speed is limited to 250 km/h (155.34 mph). Efficiency is impressive: just 6.0 liters of fuel per 100 km (39.20 US mpg) on average, which corresponds to only 158 grams of CO2/km (254.28 g/mile).
The second version of the 3.0 TDI, which will follow somewhat later, does even better in this discipline. It produces 150 kW (204 hp) between 3,750 and 4,500 rpm. With front-wheel drive and the stepless multitronic automatic transmission, it really flaunts its efficiency: 139 grams CO2 per km (223.70 g/mile) and an average fuel consumption of 5.3 liters per 100 km (44.38 US mpg) are groundbreaking figures. With the new Efficiency TDI, the front-wheel drive Audi A7 Sportback accelerates from 0 to 100 km/h (62.14 mph) in 8.1 seconds and reaches a top speed of 234 km/h (145.40 mph).
With the 3.0 TDI with 150 kW (204 hp), the timing of the cam shafts, the turbocharger and the common rail system with an injection pressure of 2,000 bar have been designed specifically for low fuel consumption. With front-wheel drive, the V6 diesel produces 400 Nm (295.02 lb-ft) of torque. The power is continuously available between 1,250 and 3,500 rpm. With quattro all-wheel drive, it is 450 Nm (331.90 lb-ft) of torque that is available between 1,250 and 3,500 rpm.

2011 Audi A8 The design of luxury cars

Audi design is always
fascinating in its complex intelligence

Advanced illustrations of its future product lineup was released in 2008 by Audi which included the latest D4 A8. It was further revealed that the latest A8 will be the beginning of a new styling language for the car maker. With the third generation it will be more aggressive, sharper and clear-cut.
However, with the succeeding generation, the theme was styling with softer, smoother lines. According to Audi, the first generation was very rigid and inflexibly designed. The latest illustrations are somewhat different from the initial previews with its new slotted lower air intakes in the front air dam and modified LED-edge headlamps.The distinctive elements include a large single-frame grill, LED daytime running lights and a profile like that of a coupe. The final curb weight of the new model will come between 3,630lb (1,560kg) and 4,180lb (1,900kg) contingent on the specs of the model.
It will still come with the aluminum spaceframe body which will cut more than 150kg of weight in contrast to the conventional steel body. The design of the upcoming model is a development of the present model as what can be observed from its illustrations. What gave it away as the next generation version are its extended fender flares, stretched wheelbase and broader track. A test model, which has kept under the present D3 body, has been seen going through cold weather testing several times already. Together with this, it is also reported that for the very first time a new entry-level version, which will come with a turbo-charged 4-cylinder unit, will be made available.
This minor styling will have to suffice for at least one more year as the succeeding generation 'D4' A8 which was reported to arrive in the middle of 2010 as a MY 2011 car. Since it began selling in 2003 the Audi A8 has received only a minor facelift just to make it appear fresh beside the Lexus LS, the Mercedes-Benz S-Class and the BMW 7-Series which was revealed just of late.

2011 Audi A8 profilation of this cars :

Audi has launched the next generation of the Audi A8 - the sportiest sedan of the luxury class sets new standards. Its elegantly styled body with the Audi Space Frame (ASF) is aluminum, the engines are powerful and highly efficient, and the power transmission and running gear combine dynamics with convenience. The new flagship's generously designed interior captivates with its luxurious equipment, newly developed control system MMI and the excellent quality of its workmanship. Innovative assistance systems lend even more confidence to driving.

Design

Audi design is always fascinating in its complex intelligence. The outer skin of the new Audi A8 conveys homogeneity, as if modeled from a full volume. A coupé-like roof line lets the silhouette flow; sculptured surfaces conveying calmness and prestige contrast with sharp lines. The new A8 underscores the leading position maintained by Audi in the field of automotive design. Representing the cutting edge in many innovative technologies, the Audi A8 indicates this role through new and progressive design elements.
5137 mm (16.85 ft) in length, with a 2992 mm (9.82 ft) wheelbase, 1949 mm (6.39 ft) in width and 1460 mm (4.79 ft) in height - the new luxury sedan is generously proportioned. The Audi A8 significantly exceeds in length and width both its predecessor and its competitors. Its height, however, remains below that of its immediate rivals in Germany - the proportions follow the dynamic line.
The Audi A8 displays its single-frame radiator grille like a proud coat of arms. Framed by a chrome edge, the grille presents a new design - sculptured, three- dimensional and rich in details. With angular upper corners, it is neatly integrated in the front section, while the prominent, horizontal chrome braces emphasize the vehicle width.
The Audi A8 looks out on the world through newly designed headlights - with xenon plus units and the innovative full LED headlights, a technology Audi was the first to introduce worldwide in the Audi R8 high-performance sports car. The adaptive light system augments the xenon plus units - it controls the swiveling modules so that they always provide the perfect lighting for intersections, the city, country roads and highways. The new all-weather light integrated into the headlights replaces the fog lights. Their traditional location in the air intakes is now occupied by the radar sensors of the optional adaptive cruise control with stop & go function.
A technological breakthrough from Audi is the networking of the headlight control unit with the optional MMI navigation plus. The navigation system analyzes the route ahead and relays the data to the light computer to activate highway lighting with its extended range while still on the ramp to the highway, for example. Before entering an intersection, the system activates the cornering light, which provides wider-angle illumination and thus enhances safety.

High-end technology: the full LED headlights

The high-end solution on board the new A8 is the full LED headlights. They give the big sedan an unmistakable appearance even in daylight and even more so after the fall of darkness. Their revolutionary optics mean a departure from the large, tubular light modules commonly used today.
The low beams comprise ten individual modules forming an arc situated below the wing-shaped chrome contour known as the "wing." Just below this is another arc of 22 white and 22 yellow LEDs for the daytime running lights and the turn signals. Their thick wall technology makes them appear from the outside as homogenous, continuous strips of light.
Located above the wing are the high beams, whose light is generated by two powerful four-chip LEDs and a free surface reflector system. An assistant switches between the high and low beams, and additional high-power LEDs generate the highway light and cornering light. A separate fan and heat sink moderate the system's temperature.
The full LED headlights offer a number of functional advantages in everyday situations. With a color temperature of 5,500 Kelvin, their light resembles daylight and thus is much less tiring to the eyes. They also offer efficiency advantages. The low beams, for example, consume only 40 watts per unit, a bit less than the already highly efficient xenon plus headlights.
The side view of the new Audi A8 also gives the image of concentrated and forward-thrusting power. Typically for the Audi line, the vehicle line makes up two-thirds of the height, with the remaining third falling to the greenhouse. From the single-frame grill Audi's characteristic Tornado line runs as a light edge just beneath the window sill. The line continues close above the wheel arches, giving the Audi A8 a powerful appearance on the road.
The surfaces below the Tornado line interpret the interplay of light and shadow, of convexity and concavity, and are statement of seriousness and timeless elegance. Proceeding downwards, the surfaces are framed by the rising dynamic line running above the side sills. Large wheels - from 17 to 21 inches in diameter - fill the wheel arches pulled out wide.
At the rear the separation edge gives an impression of sleekness, which further reinforces the impressively sculptured surfaces. A chrome strip underlines the width of the sedan, terminating in a diffuser.
The tail lights also produce an appearance both three-dimensional and striking - and typically Audi. They, too, use LED technology with 72 light-emitting diodes per unit. Chip-on-board LEDs, which can be packed tightly together with high precision, are used in many areas due to the limited amount of space available.
The tail lights, which consume only 9 watts per unit, form a trapezoidal contour that appears as an even, homogenous strip. Its upper segment is a light guide - a plastic tube; the lower section is a reflective, textured free-form surface. It is thicker than the upper segment to optically lower the center of gravity of the Audi A8's back end. The turn signal is a horizontal line. The five-segment brake light is located inside the trapezoid.

Body

Big, strong, safe and yet amazingly lightweight - the aluminum body once again sets new standards. Its low weight is a key factor for the outstanding driving dynamics, exemplary efficiency and very good comfort of the new A8. Audi, the lightweight design pioneer of the automotive industry, again demonstrates its leadership role.
Fifteen years ago the four rings brand introduced the technology of the Audi Space Frame (ASF) into production - with the first Audi A8 generation. ASF has proven its merit outstandingly; and now Audi is again using it in a much more advanced form. In its basic design the ASF body brings a latticed framework to mind. Its skeleton comprises extruded sections and pressure diecast parts of aluminum. The aluminum panels - such as the roof panels and the side panels - are joined by friction connections.
Depending on their tasks, the components of the ASF body fully differ in shape and cross-sectional area. For example, the A-pillar nodes of the new Audi A8 - one of 25 castings in the body - interconnect the longitudinal member, the sill, the omega cross-member, the windshield crossmember, the roof frame and the suspension strut mount. The lateral roof frame, on the other hand, is formed by a single extruded section; its cross-section changes flexibly from the A-pillar to the C-pillar.
Audi has substantially increased the strength of the higher-strength body components in the new Audi A8, thereby significantly reducing both material thickness and weight.
One of the keys for this is a novel composite material for the aluminum panels. The use of this new, high-strength aluminum alloy alone enabled a weight saving of 6.5 kilograms (14.33 lb).

Engines

Superior power and high efficiency - the new Audi A8 makes its debut on the market with a strong V8 engine. With 372 hp, they never fail to impress with their superior power and mighty but discreet propulsion. All engines feature direct fuel injection, and consume 15 percent less fuel than their respective predecessors.
The engine in the A8 has intelligent elements from Audi's modular efficiency system on board. During deceleration the recuperation system converts the kinetic energy to electric power, which is buffered in the battery. In the innovative thermal management a computer monitors numerous actuators for the ideal distribution of the heat flows between the engine, transmission and interior in any situation. After the cold start the engine is temporarily fully uncoupled from the cooling circuit, considerably shortening the warm-up phase with its high loss of friction.
The 4.2 FSI draws 273 kW (372 hp) of power from 4,163 cm3 displacement, generating its maximum of 445 Nm (328.22 lb-ft) torque at 3,500 rpm. It accelerates the Audi A8 from zero to 100 km/h in 5.7 seconds, with the propulsion ending (as in all engine variants) at the electronically controlled speed of 250 km/h (155.34 mph).
The most important reason for this enhanced power is the reduction of internal friction, especially in the chain drive for the camshafts and auxiliaries. The controlled oil pump with changeover between two pressure stages operates with high efficiency. Like all gasoline engines from Audi, the V8 has FSI direct injection. It allows a high compression of 12.5:1, for increased power and efficiency.

the sportiest sedan of the luxury class

Undeniably, the Quattro was such a runaway hit that the model Instantly, the Quattro propelled the Audi name to the top of the race car world when the vehicle began to win race upon race. In 1980, Audi shook the automotive world to its foundation when it released its Quattro sports car, a vehicle with full time all wheel drive and a turbocharged engine. New models were developed several of which were also marketed as Volkswagen models for that era. By the late 1960s, Audi began what many consider to be its historic run to the top of automotive excellence.
In 1964, the Volkswagen group purchased Audi from Daimler and to this day Audi remains a significant part of the Volkswagen establishment. Continuous growth throughout the 1950s highlighted by Daimler's acquisition of the company in 1958 fueled further expansion. One year later thanks to state loans and Marshall plan assistance, a resurrected Audi was back on the scene producing a delivery van and a motorcycle. Reparations was the rallying cry when World War II ended, thus the Soviet Union who was occupying the eastern portion of Germany during the postwar era, appropriated the company, took all of its assets, and by August 1948 the company no longer existed.
August Horch lived to see that big day, but he also witnessed the dismantling of the company following the end of the second world war. Horch was absorbed by Audi and makes up one of the four rings. Yes, you guessed it: the Horch company that originally booted Mr. Indeed, the "four rings" logo of the company represents the union of four distinct German automotive manufacturers under the auspices of Audi.
In between a pair of devastating world wars, the modern Audi company began to take shape. Guess which name is known today? So, although he could legally no longer use his family name, the Latinized version of the same won out. In German, Horch means "hark" and the word "audi" is the Latin translation of horch/hark. Originally, Horch tried to use his family name, but German courts ruled against him thus the Audi name was selected instead.
By 1910, Horch himself was booted out of the company that sported his name so he set up shop elsewhere and began to sell cars under the Audi moniker. Demand for these models propelled Horch to expand production and move to a larger manufacturing facility where a newer, more powerful model cranking out a then-amazing 10 horsepower was released. August Horch founded Horch Automotive in Cologne, Germany in 1899, and began manufacturing cars in 1901 which featured a horizontal engine producing upwards of 5 horsepower. An odd start almost scuttled the company's plans, yet today Audi has risen above adversity and is producing cars that are world renowned in quality and engineering. For nearly 100 years, the Audi brand has been synonymous with producing high quality, reliable, and well engineered vehicles.
German sport luxury brand Audi has played a strong role in helping to shape consumer tastes and influence the entire European touring market.


2011 Audi A8 L profilation of this cars :

The new Audi A8 is a concentrated high-tech package that confirms the Audi claim to technical leadership - "Vorsprung durch Technik". And now the brand is introducing the top version of its flagship model. The Audi A8 L W12 quattro, with a long wheelbase and a twelve-cylinder engine, sets new standards of luxury, dynamism and efficiency in the top automobile manufacturing league. The Audi A8 L is being launched with a twelve-cylinder engine, but by the end of the year will be available with all the engines currently offered for the A8.
What's fascinating about the Audi A8 L is its supremely powerful presence; its design is clearly derived from the brand's genes and yet has undergone further refinement. The long wheelbase does not disturb its taut outlines, which remain as athletic as they are elegant.
With an overall length of 5,267 millimeters (17.28 ft), the new Audi A8 L is 130 mm (0.43 ft) longer than the regular version. The wheelbase has grown by the same amount, to 3,122 mm (10.24 ft). The width remains unchanged at 1,949 mm (6.39 ft); the height has increased by 2 mm (0.08 in) to 1,462 mm (4.8 ft). Audi's new top model is both longer and wider than its main long-wheelbase competitors.
The Audi A8 L has a body built from aluminum using the Audi Space Frame (ASF) principle and therefore weighing about 40 percent less than a comparable steel body. The ASF body structure is built up from cast elements, extruded sections and sheet aluminum, with integral B-posts made from form-hardened ultra-high strength steel. This body's tremendous rigidity is the key to the car's precise handling, low interior noise levels and high passive safety for the occupants in the event of an accident.
Among the high-end technologies featured on the A8 model line are the optional LED headlight units (standard on the Audi A8 L W12 quattro) with all lighting functions performed by LEDs. With this bright, high-efficiency light, Audi opens a new chapter in the history of automobile lighting technology.
Subtle visual details distinguish the Audi A8 L W12 quattro from the other cars in this model line. The single-frame radiator grille with integral grid structure has a high-gloss black paint finish and special chromed horizontal bars. There are also chromed inserts of new design in the air inlets, and chromed applications on the exterior mirrors. W12 badges are displayed on the single-frame grille and at the rear of the car. The exhaust system has two trapezoidal-pattern tailpipe trims neatly integrated into the rear bumper.

Abundant space: Rear-seat area

The full extra length of this sedan benefits rear-seat passengers. The back doors are longer, for even more convenient entry, and the space available inside can only be described as opulent. Rear passenger comfort can be enhanced even more if two separate power-adjustable seats are ordered. These can be heated, ventilated and adjusted in a variety of ways: forward and back, seat cushion depth and seat back angle with top section adjustable separately. There is also a fully adjustable lumbar support. The front passenger's seat can also be moved from the rear if extra space is needed.
Between the individual rear seats that are standard equipment in the Audi A8 L W12 quattro a full-length console can be ordered as an optional extra; it extends back from the center tunnel to the rear shelf, and can be specified with integral items such as a folding table or a refrigerator. Separate controls for the rear air conditioning are also standard. The luxury four-zone automatic air conditioning is controlled by no fewer than 25 adjusting motors.
Another high-end feature of the long-wheelbase Audi A8 is the reclining seat behind the front passenger's seat. The angle of the seat cushion can also be adjusted. The occupant can be massaged by ten air-filled compartments; four programs can be selected at a remote control. The feet rest on a power-adjustable support at the base of the front passenger seat back. Heating, ventilation and the luxury head restraint are integral features of the reclining seat. A folding table, additional wood and leather trim, a refrigerator and a Rear Seat Entertainment system with two 10.2-inch screens are among the features that promote relaxed travel or alternatively concentrated work in this mobile lounge.

Fine materials: Interior design

The quality of workmanship in the Audi A8 L is simply first-class - from the restrained ambient lighting through the accurately fitted switches with their precise click action. Fascinating aspects of the car's interior are the slim, clear outlines and the stylish materials with their modern look.
Audi design selection brass beige carefully combines well-matched colors with individual materials and comfort-oriented equipment items. The roof-mounted grab handles and rear console have additional fine wood trim.
Valonea leather is tanned exclusively with plant extracts and is especially soft and able to "breathe" actively. Audi also supplies a loose cushion for rear-seat passengers' use. Like the head restraints and the selector lever for the eight-speed tiptronic automatic transmission, it is trimmed with buckskin that is exceptionally soft and supple but also hard-wearing.
Another optional extra, the panoramic glass roof, has two glass panels that allow plenty of light to reach the car's interior. Both sections can be tilted up and the front one also opened extra-wide. Sun blinds are provided for both panels to keep out direct sunlight.

The Audi A8 L W12 quattro: Splendor and efficiency

Twelve cylinders are the ultimate engine configuration, a tradition that still applies in the large luxury car class. The first-generation A8 was available with an engine of this type from 2001 on, and a developed version could be obtained from 2004 on in the following model. Audi's engineers have now thoroughly revised the W12. Its displacement has been increased, and gasoline direct injection boosts its output and its efficiency.
The 6.3 FSI engine has an output of 368 kW (500 hp) and delivers its peak torque of 625 Nm (460.98 lb-ft) at engine speeds at 3,250 rpm. It gives the long-wheelbase Audi A8 the kind of performance normally expected of a sports car: it sprints from 0 to 100 km/h (62.14 mph) in only 4.9 seconds and effortlessly reaches its governed top speed of 250 km/h (155.34 mph).
A fascinating flow of power is available in every situation, but the fuel consumption too sets new standards: the EU cycle test result is only 12.0 liters per 100 kilometers (19.6 US mpg), a figure well below that of competitors' cars with V12 engines. The previous 6.0-liter engine, which had a power output of 331 kW (450 hp), recorded a fuel consumption of 13.6 l/100 km (17.3 US mpg) - the difference of 1.6 l/100 km is equivalent to a 12 percent improvement.
The engine is known as the W12 because of its unusual layout: it has four rows of three cylinders with a 15-degree included angle between the two offset rows of cylinders in each broad cylinder block. The V angle between the two blocks is 72 degrees. This layout makes the W12 engine exceptionally compact: only just over 50 centimeters (19.69 in) long and therefore distinctly shorter than a V8. Height and width are both in the region of 70 centimeters (27.56 in).
The W12, in its latest form with a displacement of 6,299 cc, is an undersquare design. Its bore and stroke are 86.0 and 90.4 millimeters (3.39 x 3.56 in) respectively. Compared with the previous version the engineers have enlarged the cylinder bore. The forged crankshaft has a 12-degree angle of crankpin offset, so that the mixture in the 12 cylinders is ignited at the ideal interval of 60 degrees. The engine therefore runs exceptionally smoothly, and the car's occupants are unlikely to sense any of this supreme power at work unless it is at high engine speeds and severe loads.
The W12 engine weighs only 247 kilograms (545 lb), an impressive value to which the crankcase makes a major contribution. This is a lightweight, high-strength aluminum-silicon alloy casting with a gray cast iron lower cross-member into which the bearing pedestals are embedded. The pistons are forged from a high-strength light alloy and have angled crowns because of their V position in the cylinder blocks.
Each of the W12 engine's aluminum cylinder heads contains two camshafts; these can be repositioned hydraulically by an amount equivalent to 52 degrees of crankshaft rotation. Altogether, the four camshafts operate 48 valves by way of low-friction roller cam followers, and are themselves driven by chains from an intermediate shaft.
For use in the long-wheelbase A8, Audi's engineers have converted the W12 engine to FSI gasoline direct injection. This involved considerable modifications to the cylinder heads. Fuel is injected into the combustion chambers at a pressure of up to 130 bar. A high 11.8:1 compression ratio boosts power output and efficiency. The inlet ports are specially shaped to impart swirl to the incoming airflow and make combustion more efficient.
The W12 engine's low fuel consumption compared with its competitors is to a large extent due to Audi's modular efficiency platform. These are used in the entire A8 model line. The crankshaft and timing chains have been intensively optimized to reduce friction, and a recuperation system recovers energy that would otherwise be wasted when the car is braked. The innovative thermal management system shuts down the coolant circuit for a time after the cold engine has been started. This warms up the engine oil more rapidly and shortens the operating period in which friction is still high.

Safe and sporty: Transmission

The transmission makes a major contribution to ensuring the high efficiency of the Audi A8 L. The eight-speed tiptronic shifts smoothly and quickly, with the individual gears closely spaced but with a generous overall spread from low to high. Gear shifts are performed electronically ("shift by wire") from an elegant yacht-style selector lever or at steering wheel paddles.
The center differential, the main component in the quattro permanent all-wheel drive train, divides the torque flow from the engine in a sporty manner, with 60 percent to the rear axle and 40 percent to the front in regular driving conditions. But if the situation changes, up to 60 percent of the torque can be sent to the front, or 80 percent to the rear. An optional sport differential splits the torque input actively between the left and right rear wheels.

2011 Audi Q7 profilation of this cars :

The Audi Q7 is the large Audi for the sporty individualist - the high-performance SUV for sport, leisure, family and business. Now Audi has made it even more powerful and efficient, with a choice of three new V6 engines and an 8-speed tiptronic transmission.

Engines: a new range

Even more power, even higher efficiency: Audi has revised the engine lineup for the Q7. The two gasoline engines, both V6 units but with different power outputs, are new, and so is the second-generation V6 TDI. A mighty V8 diesel completes the range. All the engines for the Audi Q7 combine two technologies: forced induction and direct fuel injection. A high-performance recuperation system that recovers energy during braking is also a standard item with all six- and eight-cylinder engines.
The new 3.0 TFSI gasoline engine embodies Audi's downsizing strategy: replacing engine displacement with supercharging. Within the 90-degree angle formed by its cylinder blocks there is an engine-driven supercharger that compresses the intake air. Two charge-air intercoolers prevent the air temperature from rising, so that the engine draws in more oxygen for the combustion process. Vigorous thrust and spontaneous throttle response make the 3.0 TFSI engine, with its sonorous note, an ideal source of power for the large high-performance SUV from Audi.
Two versions of the supercharged V6 are available. The basic version develops 200 kW (272 hp) and has a maximum torque of 400 Nm (295.02 lb-ft) over a broad engine-speed range from 2,250 to 4,750 rpm. It accelerates the Audi Q7 in 7.9 seconds from a standing start to 100 km/h (62.14 mph) and gives it a top speed of 222 km/h (137.94 mph), or 225 km/h (139.81 mph) with adaptive air suspension.
The more powerful version of the 3.0 TFSI delivers 245 kW (333 hp) and a torque of 440 Nm (324.53 lb-ft) between 2,900 and 5,300 rpm. 100 km/h (62.14 mph) are reached in 6.9 seconds, with powerful forward progress continuing until 243 km/h (150.99 mph) are reached; with adaptive air suspension the top speed is 245 km/h (152.24 mph). Both versions of the 3.0 TFSI are impressively efficient: in the EU fuel consumption test cycle they are content with 10.7 liters per 100 kilometers (21.98 US mpg). Compared with the previous engines, the 3.6 FSI and the 4.2 FSI, fuel consumption has been reduced by 1.4 and 2.0 l/100 km - 12 and 16 percent respectively.
The second-generation 3.0 TDI, a new development, has effectively nothing in common with its predecessor - apart from plenty of power! It has a rated output of 176 kW (240 hp) and a constant 550 Nm (405.66 lb-ft) of torque all the way from 1,750 to 2,500 rpm. This V6 diesel accelerates the Audi Q7 from a standstill to a typical main-road speed of 100 km/h (62.1 mph) in 7.9 seconds and reaches its top speed at 215 km/h (133.59 mph) or, with adaptive air suspension, 218 km/h (135.46 mph). Its fuel consumption is impressively low, averaging 7.4 liters per 100 km (31.79 US mpg), which is equivalent to CO2 emissions of 195 grams per kilometer (313.82 g/mile). This is an improvement of 1.7 l/100 km or 19 percent.
The latest 3.0 TDI engine weighs much less than before: 198 kilograms (436.52 lb), a reduction of 20 kg (44.09 lb). A new chain-driven timing gear and a complex cylinder wall machining process have reduced internal friction. The new turbocharger is exceptionally responsive, making itself felt as rapid torque buildup. The common rail injection system has also undergone further development: it has a maximum operating pressure of 2,000 bar and can therefore inject fuel in an extremely precise spray pattern.
The crankcase and cylinder heads of the new 3.0 TDI have separate cooling water circuits connected together by valves. During the warm-up phase and when loads are not high, the coolant is not circulated in the engine block. This saves energy and raises the oil more quickly to its regular operating temperature. The new start-stop system switches off the engine when the Audi Q7 comes to a standstill.
Audi also offers its customers a second version of the V6 TDI: the 3.0 TDI clean diesel. It already meets the exhaust emission limits laid down in the Euro 6 standard, which does not come into force until 2014, and the tough US regulations as well. Sensors in the combustion chambers, a common-rail fuel injection system with a delivery pressure of up to 2,000 bar and a high-performance exhaust gas recirculation system keep untreated exhaust emissions to a minimum. A DeNox catalytic converter in the exhaust system reduces the remaining oxides of nitrogen by means of an additive. The 3.0 TDI clean diesel also develops 176 kW (240 hp) and has an impressive 550 Nm (405.66 lb-ft) of torque between 2,000 and 2,250 rpm. It takes the Audi Q7 from a standstill up to 100 km/h (62.14 mph) in 8.1 seconds and gives it a top speed of 215 km/h (133.59 mph), or 218 km/h (135.46 mph) with adaptive air suspension. Its average fuel consumption is 8.4 liters per 100 km (28.00 US mpg).
The Audi Q7 4.2 TDI has also had its fuel consumption drastically reduced - from 9.9 (23.76 US mpg) to 9.2 liters per 100 km (25.57 US mpg) - by installing a 2,000-bar fuel injection system and minimizing internal friction. Yet at the same time the V8 diesel, with its unchanged power output of 250 kW (340 hp), delivers more torque than before. It now supplies a vigorous 800 Nm (590.05 lb-ft) between engine speeds of 1,750 and 2,750 rpm. The big TDI engine gives the Audi Q7 performance figures worthy of a sports car. It accelerates from 0 to 100 km/h (62.14 mph) in 6.4 seconds and has a top speed of 242 km/h (150.37 mph).

Power transmission: eight speeds are standard

Audi has given all six- and eight-cylinder Audi Q7 versions a new automatic transmission. The eight-speed tiptronic lowers fuel consumption by about five percent. It is based on the six-speed unit, but with another friction-clutch shift element added. Being able to shift between eight ratios keeps the jumps in engine speed low: the engine always runs close to its ideal operating point. All gear shifts are fast, flexible and take place extremely smoothly without delay.
At 7.25 to 1, the overall spread of ratios in the eight-speed tiptronic is unusually wide. In the lower ratios the Audi Q7 accelerates powerfully; in the higher ratios it rolls along efficiently at low engine speeds.
To cut fuel consumption still further, the torque converter lockup clutch eliminates slip even at low engine speeds. Any engine vibration that could occur as a result is suppressed by the new damper in the torque converter until scarcely any trace can be detected.
Drivers can choose between the D and S programs - or make their own gear shifts at the transmission selector lever or the optional steering-wheel paddles. In combination with the 3.0 TDI the new eight-speed tiptronic achieves an exceptionally high level of efficiency. Its oil cooler is heated after a cold start by hot coolant from the engine's cooling system. An electric oil pump makes operation of the Audi Q7's start-stop system possible: it maintains oil pressure in the hydraulic circuit when the engine stops, and closes the clutch for restarting.
The eight-speed tiptronic transmission transfers engine power to the quattro permanent all-wheel drive train. This splits the power in a sporty manner, with 40 percent going to the front and 60 percent to the rear wheels, but in certain on- or off-road situations, the mechanical-action center differential can direct up to 65 percent of the power to the front or up to 85 percent to the rear.

The chassis: agile and safe

The Audi Q7 is one of those personalities who are at home wherever they may be. On the road it excels with its precise, sporty handling, and where the hardtop surface ends it demonstrates impressive offroad characteristics. The suspension uses double wishbones made of aluminum, attached to separate subframes. The wheel bearings have been optimized to reduce friction. The servotronic steering varies the degree of power assistance according to the vehicle's speed.
The optional adaptive air suspension (standard on the Q7 4.2 TDI and Q7 V12 TDI) with electronic shock absorber control varies the ride height to suit the actual situation. On a high-speed road it lowers the body for enhanced stability and lower fuel consumption. Across rough terrain it raises the body if a button is pressed. At the standard MMI terminal the driver can choose between five operating modes: comfort, automatic, dynamic, offroad and lift. The adaptive air suspension is also available as a dynamic S line version.
The Audi Q7 has 18-inch wheels with 235/60 or 255/55 tires, depending on the chosen engine. But other wheels up to 21 inches in diameter can be selected as optional extras. Braking is looked after by large ventilated disks. With the two most powerful engines even larger disks made from lightweight carbon-fiber reinforced ceramic material are available. They are gripped firmly when the need arises by black callipers with "Audi ceramic" lettering. The ESP stabilization program includes an off-road mode as standard that gives priority to traction on a loose surface. And when the driver encounters a steep downhill slope off-road, the hill descent assist is a useful aid.

Design and body: sculpture in motion

The design of the Audi Q7 stands for power and presence; it is the visual expression of this large SUV's character. Flowing surfaces create a moving sculpture, with the coupé-like roofline, the low window strip and the tautly curved panel surfaces being distinctive visual features. The outlines are sporty, strong and elegant.
The Audi Q7 is 5.09 meters (16.70 ft) long, 1.98 meters (6.50 ft) wide and 1.74 meters (5.71 ft) high. Its wheelbase of 3 meters (9.84 ft) creates a luxurious amount of space inside. The front-end styling is dominated by the large singleframe grille with chromed surround, and the headlamps. As an optional extra Audi can supply a xenon plus version with LED daytime driving lights and LED flashers, and also an adaptive light version with integrated turning and cornering lights as well as the low, full and highway beams.
Standard LEDs in the rear lights create a distinctive lighting pattern. The tailgate, which wraps around the rear roof posts in an S-shaped outline, and also the hood and the front fenders are made of aluminum. Audi supplies the add-on parts in a contrasting color as standard, or, if desired, in the same color as the body. The Audi Q7 always leaves the assembly line with a high-gloss package. Optional extras are the black styling package or the aluminum-look exterior package, which consists of an all-round chrome trim strip on the bumpers, door capping strips and door handles, and gives the Audi Q7 even greater sophistication. The optionally available S line exterior package also adds further visual emphasis to this SUV's sporty potential.

The interior: abundant space

The Audi Q7 sets standards for flexibility: no fewer than 27 seat configurations are possible. Depending on the wishes of the customer, Audi can supply its large SUV as a five-, six- or seven-seat version. This last version has comfortable single rear seats and a third row of seats at the back for occupants up to 1.60 meters (5.25 ft ) tall. As a standard feature, the seat backs in the second row can be folded down to provide a level cargo floor. This increases load capacity from 775 liters (27.37 cubic ft) to 2,035 liters (71.87 cubic ft) in volume.
Operation of the controls is simple and logical, and the clearly marked instruments are easy to read. For the driver and front passenger there is a choice of three seat versions: standard seats, electrically adjustable sport seats and climatized luxury seats that can be both heated and ventilated. The elegant lines of the interior, with many restrained details, communicate the typical feeling of wellbeing that the Audi driver or passenger enjoys. The ambient lighting provides subtle highlights, and many of the control elements have fine chrome trim. The workmanship is typical of Audi - quality with no compromises.
The choice of colors and materials emphasizes the distinguished character of the interior of the Q7. A variety of leather grades, headlinings and inlays are available, and for the individualist there are leather and design packages of various styles. The S line sports package uses cool black throughout the interior, with subtle accents in the trim and upholstery. Among the items it includes are sports suspension and 20-inch wheels.

Equipment and trim: the highest standards of luxury

The Audi Q7 comes with an opulent array of standard equipment features, including two-zone deluxe automatic air conditioning, high-beam assistant, an MMI radio operating system complete with audio system and eight speakers, a double load floor in the cargo area with storage compartment and a dirt tray. Roof rails are also fitted.
A standard item when the optional driver information system is chosen is the on-board computer with efficiency program. This monitors the vehicle's energy flows and displays the requirements of the most important consumers, with hints on how to reduce consumption.
The list of optional extras includes such luxury features as the convenience key, four-zone automatic air conditioning, a dark glass panoramic roof and a cool box. Items of interest for sport and leisure include an electric tailgate mechanism, baggage retaining rails and a sliding storage box. In the program of accessories are such items as a pivot-head tow hitch - the large SUV can tow a trailer weighing up to 3.5 metric tons (7,716 lb).
In the infotainment area Audi also offers a complete modular system. The top-of-the-line version has an integral hard disk drive for navigation, music, and telephone data, a color monitor with 3D graphics, a DVD player, and voice control. It can be expanded into a luxury media center with features such as a Bluetooth telephone, TV tuner, digital radio tuner, plus rear seat entertainment. A special highlight is the Advanced Sound System from Bang & Olufsen with its 14 channels, 1,000 watts of power and 14 speakers. In the cockpit area two acoustic lenses reproduce the treble frequencies; when the system is started, they extend out of the dash panel.
The range of optional equipment is rounded off by advanced driver assistance systems. The adaptive cruise control system regulates speed and following distance by means of targeted accelerating and decelerating. If a risk is detected, the integral Audi braking guard provides a warning. Audi lane assist helps the driver to stay in lane; Audi side assist employs radar to help drivers change lanes more safely. The Audi parking system advanced assists parking by means of a rearview camera.

The Audi Q7 V12 TDI quattro: the most powerful diesel SUV in the world

The Audi Q7 V12 TDI quattro is the most powerful diesel SUV in the world. Its 6-liter twelve-cylinder TDI engine develops 368 kW (500 hp) and delivers 1,000 Nm (737.56 lb-ft) of torque between 1,750 and 3,250 rpm to the six-speed tiptronic transmission. With a time of just 5.5 seconds from zero to 100 km/h (62.14 mph) and a governed top speed of 250 km/h (155.34 mph), the Audi Q7 V12 TDI quattro matches the performance of a powerful sports car, but is content with a fuel consumption of only 11.3 liters per 100 kilometers (20.82 US mpg).
The luxurious standard equipment specification of the Audi Q7 V12 TDI quattro includes 20-inch wheels, Audi ceramic brakes, xenon plus headlights, adaptive air suspension, a Bose sound system, sport seats and many other features. This top version also has a number of striking body details that identify it immediately.

By the late 1960s, Audi began what many consider to be its historic run to the top of automotive excellence.
In 1964, the Volkswagen group purchased Audi from Daimler and to this day Audi remains a significant part of the Volkswagen establishment. Continuous growth throughout the 1950s highlighted by Daimler's acquisition of the company in 1958 fueled further expansion.

Horch was absorbed by Audi and makes up one of the four rings. Yes, you guessed it: the Horch company that originally booted Mr. Indeed, the "four rings" logo of the company represents the union of four distinct German automotive manufacturers under the auspices of Audi. In between a pair of devastating world wars, the modern Audi company began to take shape.
Guess which name is known today? So, although he could legally no longer use his family name, the Latinized version of the same won out. In German, Horch means "hark" and the word "audi" is the Latin translation of horch/hark. Originally, Horch tried to use his family name, but German courts ruled against him thus the Audi name was selected instead.
By 1910, Horch himself was booted out of the company that sported his name so he set up shop elsewhere and began to sell cars under the Audi moniker. Demand for these models propelled Horch to expand production and move to a larger manufacturing facility where a newer, more powerful model cranking out a then-amazing 10 horsepower was released. August Horch founded Horch Automotive in Cologne, Germany in 1899, and began manufacturing cars in 1901 which featured a horizontal engine producing upwards of 5 horsepower. An odd start almost scuttled the company's plans, yet today Audi has risen above adversity and is producing cars that are world renowned in quality and engineering.
For nearly 100 years, the Audi brand has been synonymous with producing high quality, reliable, and well engineered vehicles. German sport luxury brand Audi has played a strong role in helping to shape consumer tastes and influence the entire European touring market.

2011 Audi R8 GT profilation of this cars :

Now even more powerful, lighter and faster: Audi presents the Audi R8 GT - a limited-production version of the Audi R8 high-performance sports car. The output of its 5.2-liter V10 has been increased to 412 kW (560 hp); vehicle weight has been reduced by roughly 100 kilograms (220.46 lb). The Audi R8 GT accelerates from zero to 100 km/h (62.14 mph) in 3.6 seconds and reaches a top speed of 320 km/h (198.84 mph).
The R8 high-performance sports car has been a winner from the very beginning. This applies to both the production models, winners of the "World Performance Car" Award in 2008 (R8) and in 2010 (R8 V10), and to the race car, the R8 LMS, which won 23 races in its first season and claimed three championships. The genes of the race version are now coming to the street - in the Audi R8 GT. The exclusive series is limited to 333 units. Each Audi R8 GT has a badge with its production number on the shift lever knob.

Consistent use of lightweight construction: 100 kilograms (220.46 lb) trimmed

The production Audi R8 V10 5.2 FSI quattro is already a shining example of the Audi's lightweight construction philosophy. Its aluminum Audi Space Frame (ASF) body weighs only 210 kilograms (462.97 lb). The aluminum body panels are joined to the frame of extruded profiles and cast nodes by means of positive and friction connections. The engine frame is made of ultra lightweight magnesium.
The ASF body is largely hand-built at the Neckarsulm plant in a complex manufacturing process. The extremely high strength of the body is the basis for the high-performance sports car's precise handling, and it also offers good vibration comfort and first-rate crash safety.
Thanks to the ASF body, the production R8 5.2 FSI quattro weighs only 1,625 kilograms (3,582.51 lb) - with quattro permanent all-wheel drive and optional R tronic transmission. This made it all the more difficult for the engineers to once again achieve substantial weight savings. They took an elaborate approach involving every aspect of the vehicle, and in the end the scales came to rest at 1,525 kilograms (3,362.05 lb).
The windshield of the Audi R8 GT is made of thinner glass; the bulkhead between the passenger cell and engine compartment, as well as the window in the rear hatch are made of strong, lightweight polycarbonate. These three modifications saved nine kilograms (19.84 lb). The fixed rear wing is good for an additional 1.2 kilograms (2.65 lb); thinner sheet metal and additional cutouts shaved 2.6 kilograms (5.73 lb) from the aluminum hatch over the 100 liter (3.53 cu ft) luggage compartment at the front of the car.
The long rear hatch is made of carbon fiber-reinforced plastic (CFRP) - an advantage of 6.6 kilograms (14.55 lb). The rear bumper and the sideblades of this same material save an additional 5.2 and 1.5 kilograms (11.46 and 3.31 lb), respectively. With its minimal weight and extremely high strength, CFRP is the ideal material for a high-performance sports car, and Audi has broad-based expertise in its use.
The engineers also fought to shave every possible gram of weight from the technical components of R8. They shaved one kilogram (2.20 lb) from the power brake system, four kilograms (8.82 lb) from the aluminum caps of the brake discs and 9.4 kilograms (20.72 lb) from the battery. The engineers also found 2.3 kilograms (5.07 lb) in the air intake module and 2.8 kilograms (6.17 lb) in the insulation of the engine compartment.
The interior also harbored substantial weight-savings potential. The new, lightweight carpeting accounts for 7.9 kilograms (17.42 lb); the bucket seats with a chassis of glass-reinforced plastic (GRP) account for 31.5 kilograms (69.45 lb). Numerous additional detailed measures targeted the interior, the exterior and the technology, such as higher-grade, lighter steel for the exhaust system's tailpipes.

Even sharper and more effective: the design

The design of the Audi R8 GT is the expression of concentrated power - a beautiful, technical sculpture measuring 4.43 meters (14.53 ft) long, 1.93 meters (6.33 ft) wide and only 1.24 meters (4.04 ft) high. The exterior underwent numerous modifications that further sharpened the appearance. Many of them also reduce the weight and enhance the aerodynamics. The Audi R8 GT produces even more downforce when driven fast than the production model - without any increase in the Cd value (0.36) or frontal area (1.99 m2) (21.42 sq ft).
The frame of the single-frame grille, its struts and the slats in the air intakes are finished in matt titanium gray; the grille is painted matt black. The splitter under the bumper has a double lip and is made of carbon. Slender, curved flics at the corners of the nose increase the downforce on the front axle and are also made of a carbon fiber composite.
One highlight of the Audi R8 GT are the standard LED headlights, which use light-emitting diodes for all functions. They produce bright, homogeneous light, have a long service life and low energy consumption. The headlights also have an attractive and distinctive appearance. The daytime running lights each comprise 24 LEDs and appear as a continuous band. The reflectors are reminiscent of open mussel shells.
The defining element of the side view are the sideblades, which direct air to the engine and in the Audi R8 GT are also made of matte carbon. The same material is used for the reduced-size housing of the side mirrors, which are mounted on an aluminum base. The 19-inch wheels feature an exclusive five twin-spoke Y design in a titanium-look finish. The front fenders sport "GT" badges.
The modifications to the rear of the car are particularly apparent, beginning with the fixed wing of matte carbon. The ventilation louvers on both sides of the rear hatch and the CFRP bumper, which integrates the large, round tailpipes and vents for the wheel wells, have been redesigned. The larger diffuser is made of carbon fiber composite; the license plate bezel and the wide slats at the rear are in matte titanium gray. The tail lights, which also use LED technology, have dark housings with panes of clear glass.
Audi offers the R8 GT in a choice of four body colors: Samoa Orange metallic, Suzuka Gray metallic, Ice Silver metallic and Phantom Black pearl effect.

Breathtakingly powerful: the 412 kW (560 hp) 5.2 FSI

The modified V10, whose cylinder head covers are painted red, gives the Audi R8 GT breathtaking performance. The R8 GT sprints from a standing start to highway speed in 3.6 seconds, and from zero to 200 km/h (124.27 mph) in 10.8 seconds. And the thrust does not let up until the top speed of 320 km/h (198.84 mph) is reached.
Changes to the engine electronics coaxed an additional 26 kW from the ten-cylinder, which now produces 412 kW (560 hp) from a displacement of 5,204 cc. The torque curve peaks at 540 Nm (398.28 lb-ft) at 6,500 rpm, 10 Nm (7.38 lb-ft) more than in the production version. The V10 has a specific power output of 79.2 kW (107.6 hp) per liter displacement. Its power-to-weight ratio is 3.70 kilograms (8.16 lb) per kW or 2.72 kilograms (6.00 lb) per hp. The engine redlines at 8,700 rpm.
The long-stroke engine (bore x stroke 84.5 x 92.8 millimeters [3.33 x 3.65 in]), which is hand-built at the factory in Györ, Hungary, features a crankcase made of a aluminum-silicon alloy that is both lightweight and very strong. A bedplate - a frame for the crankshaft bearing bridges - further enhances its rigidity. The complete engine weighs only 258 kilograms (568.79 lb). It is characterized by a cylinder angle of 90 degrees and dry-sump lubrication, which uses a highly efficient oil pump module. Both solutions lower the center of gravity and thus improve driving dynamics.
The crankshaft is designed as a common pin shaft. The connecting rods of the opposing pistons engage a common crankpin, resulting in alternating firing intervals of 54 and 90 degrees. This unique rhythm gives the V10 its fascinating sound - a grand, technical music very much like that in racing. Two flaps in the exhaust system modulate its volume and tone as a function of load and engine speed.
The normally aspirated engine consumes an average of 13.7 liters of fuel per 100 km (17.17 US mpg) - very good fuel economy given the tremendous power. The FSI gasoline direct injection system injects the fuel into the combustion chambers at up to 120 bar of pressure. The turbulent mixture cools the cylinder walls, enabling a compression ratio of 12.5:1. A variable intake manifold and the continuous adjustment of the chain-driven camshafts ensure that the combustion chambers are fully filled. Flaps in the intake ports facilitate the formation of the mixture by inducing a tumbling motion in the inflowing air.

The drivetrain: uncompromising traction

Gear changes in the Audi R8 GT are handled by the R tronic sequential manual transmission. The electrohydraulic clutch and switching unit receive their commands electronically. It changes its six gears much faster than a skilled driver could - within a tenth of a second at high load and engine speed.
The electronic management system offers an automatic mode with the Sport and Normal characteristics, and two manual levels. It is controlled using the short gear selector lever on the center tunnel and two paddles on the steering wheel. Maximum thrust when starting is ensured by Launch Control - a program that manages full acceleration with high engine speed and minimum wheel slip when starting.
quattro permanent all-wheel drive is the ideal technology for a high-performance sports car. The central viscous coupling located at the front differential sends 15 percent of the power to the front axle and 85 percent to the rear axle during normal driving. This split harmonizes perfectly with the Audi R8 GT's 43:57 percent weight distribution. The coupling sends as much as 30 percent of the power to the front wheels within milliseconds, if necessary. A mechanical locking differential at the rear axle further improves traction. It provides up to 25 percent lockup when accelerating and up to 40 percent on the overrun.

Chassis even tauter and more precise

The Audi R8 GT high-performance sports car is a driving machine with breathtaking lateral acceleration and lightning-fast, nearly instantaneous reactions. Its engine is mid-mounted close to the vertical axis; its mass is almost negligible during fast direction changes. The Audi R8 GT is dynamic, precise and stable in almost every situation.
The chassis follows the classic racing design - double wishbones made of aluminum locate the wheels. The hydraulic, power-assisted rack-and-pinion steering has a direct 16.3:1 ratio and connects the driver closely and precisely with the road. A manually adjustable coilover suspension, which lowers the body by as much as 10 millimeters (0.39 in), is standard. Higher front and rear wheel camber rates make the handling a tick more agile than with the standard model.
The 19-inch forged wheels are 8.5 J x 19 up front and 11 J x 19 at the rear, and are shod with size 235/35 and 295/30 tires, respectively. Audi will mount 305/30 tires together with optional wheels on the rear axle upon request. Cup tires, which offer the ultimate in performance on dry roads, are available for racing enthusiasts.
Audi mounts internally ventilated, carbon fiber ceramic brake disks standard. They are extremely durable and abrasion-resistant as well as particularly lightweight. Together they weigh nine kilograms (19.84 lb) less than their steel counterparts of the same size. They measure 380 millimeters (14.96 in) in diameter up front and 356 millimeters (14.02 in) at the rear. The friction rings are bolted to the stainless steel caps via elastic elements. Red anodized aluminum brake calipers - with six pistons up front - are exclusive to the Audi R8 GT.
The ESP stabilization program has been specially tuned to the Audi R8 GT and can be switched into a Sport mode at the push of a button to allow spectacular, but safe, oversteer when accelerating out of a corner. The driver can deactivate the system entirely for a trip to the race track.

Exclusive and dynamic: interior and equipment

At Audi, reducing weight means increasing performance and efficiency, but not sacrifice. The Audi R8 GT, which Audi sells in Germany for €193,000, comes with an automatic climate control system and power windows, a navigation system with MMI operating logic and a powerful sound system. A 465 watt, ten-channel Bang & Olufsen sound system, a CD changer and the Audi Music Interface are available as options. As always with Audi, the interior shows loving attention to detail. Rich materials spoil the occupants with a fine look and feel.
The ergonomic interior is adorned in sporty black and dark gray. The steering wheel, the headliner, the roof posts, the knee pad, the parking brake lever and the bucket seats are covered with Alcantara accented with contrasting stitching. A synthetic sharkskin-look material that feels slightly rough to the touch is applied to the bulkhead, the door liners, the instrument cowl and the dashboard. The "monoposto" - the arch in the cockpit - is made of matt carbon.
The instrument cluster features white dials with "R8 GT" badges. The newly designed selector lever is made of CFRP and aluminum; the center tunnel and the door liners sport decorative inlays in the body color. The door sills feature trims of matt aluminum decorated with the "R8 GT" logo.
A number of exclusive features are available as options for the Audi R8 GT. Exterior options include two alternative wheels, a body-color front splitter and a CFRP engine compartment lining. Carbon elements on the doors, the tunnel, in the cockpit and on the instrument panel are available as interior options. Others include a multifunction leather steering wheel, seat belts in red, orange or gray, floor mats with the "R8 GT" logo and CFRP door sill trims illuminated in red. If desired, Audi will fit seats with carbon frames, which are somewhat lighter than the CFRP shells. The Alcantara seat covers are optionally available with an embroidered "R8 GT" logo.
A race package is available for racing enthusiasts. It includes a bolt-in roll bar in red or black, which has both road and type approval, as well as road-approved four-point belts in red or black, a fire extinguisher and a kill switch for the battery. An optional front bar module for motorsports evens includes a rotary lock for the four-point seatbelt and turns the roll bar into a full cage. Buyers looking for more comfort and convenience can choose cell phone preparation with an innovative belt microphone. Audi also offers a full leather package, control elements in leather with contrasting stitching and a cruise control system as options. The parking aid is included with the standard equipment.
