For 2008, the Audi A4 receives only minor changes. Exterior features that were previously available as part of the sedan and wagon's optional S line sport package are now standard. This means that front and rear bumpers have been revised, as has the lower side door trim. An integrated trunk lid spoiler has been added, along with a new front grille and S line badging. To reflect this, the optional S line Sport Package has been trimmed to include just a sport-tuned suspension, sport three-spoke steering wheel, aluminum trim, 18-inch wheels and leather upholstery with unique stitching. On the A4 Cabriolet, heated front seats are now standard. An optional iPod interface is available on all 2008 Audi A4s.
Many of the world's major religions bear a similar theme: A messiah comes, bringing with him enlightenment and a path to a better way of living. Audi had its very own messiah of sorts with the A4. Bad press regarding unintended acceleration (based on reports that were later shown to be unfounded) tarnished the manufacturer's image in the late '80s and early '90s, sending sales into an unholy tailspin. Launched in the mid-'90s, the Audi A4 -- buoyed by crisp handling, superb road manners and elegant visage -- proved compelling enough to reinvigorate the brand. Now in its third generation, the Audi A4 is as enticing as ever -- and Edmunds.com's editors have voted it a top pick for several years running.
The 2008 Audi A4 is catnip for drivers who crave the finer things. One of the few entry-level luxury cars available as a sedan, convertible and wagon, the Audi A4 morphs to please everyone from bustling families to solitary singles. Slide inside and you'll find a cabin that takes the "entry" out of "entry-luxury." Gauges offer the sort of soothing lighting you'd find in a chic late-night bistro, and the car's interior materials and design would be right at home in the expensively outfitted lobby of a premier Hollywood talent agency. On the move, the A4 has a solid feel to it, an attribute no doubt helped by the car's commonly fitted Quattro all-wheel-drive system.
Compromises are few, but they do exist. Neither A4 engine is a powerhouse, for instance, as the turbocharged 2.0-liter is somewhat lacking when it comes to off-the-line torque and the 255-horsepower V6 is increasingly outclassed by competitors putting out more than 300 hp. Another potential negative is the rear seat, which isn't as roomy as the accommodations in some rivals. Hard-core enthusiasts might also criticize the A4's handling, which is softer and less responsive than the premier sport sedans in this price range. However, many buyers will find that the Audi's high level of feedback compensates for its somewhat slower reflexes.
That's not to say you shouldn't consider other models if you're shopping in this highly competitive class. The BMW 3 Series, Infiniti G35 and Lexus IS are all sportier in demeanor, for instance, while the new Cadillac CTS boasts more rear-seat room and the Mercedes-Benz C-Class benefits from a fresher, more stately design. And depending on your priorities, cars like the Acura TSX and Volvo C70/S40/V50 might be worth your attention as well. While all of these cars have their merits, if you end up with a 2008 Audi A4, we doubt you'll be dissatisfied. Thanks to its versatile yet fun-loving demeanor, range of body styles, reasonable price tag and best-in-class cabin, the A4 could well be the salvation for those searching for a great all-around entry-level luxury car.
The 2008 Audi A4 comes built to satisfy in a plethora of body styles. A sedan, convertible (Cabriolet) and wagon (Avant) are offered. The trims are defined by the engines that power them: 2.0T and 3.2. The A4 2.0T sedan and wagon come standard with 16-inch alloy wheels, a power driver seat, a sunroof, dual-zone automatic climate control and a 10-speaker, six-CD/MP3 changer. Pump up the swank quotient with a 3.2 model, which adds 17-inch wheels, wood flourishes, leather upholstery, heated front seats and a power front-passenger seat. A4 Cabriolets have an automatic soft top and equipment lists largely similar to those of the sedan and wagon.
Most of the 3.2's extra features can be added to the 2.0T as part of the Premium and Convenience Packages. The latter also includes adaptive bi-xenon headlights and auto-dimming mirrors. For both trim levels, Audi offers an S line sport package with 18-inch wheels, a sport-tuned suspension and specialized interior trim. A4 buyers can also opt for heated rear seats (via a cold weather package), a navigation system, an upgraded 10-speaker Bose sound system (which includes satellite radio), Bluetooth connectivity, a dedicated iPod interface and the "Titanium" styling package with 18-inch wheels and several wood and metallic embellishments. The 2.0T also offers a Special Edition package which adds 17-inch alloy wheels, leather seating and satellite radio. Available on the A4 3.2 only are driver-seat memory, rear park assist and premium-grade "Volterra" leather upholstery.
The A4 is available with one of two engines. A 2.0-liter turbocharged inline-4 produces 200 hp and 207 pound-feet of torque, and a 3.1-liter V6 drums up 255 hp and 243 lb-ft of torque. A4 Avants are available only with Audi's Quattro all-wheel drive, but sedan and Cabriolet buyers may choose between front-wheel drive and Quattro. Quattro-equipped A4s give you the choice of a six-speed manual or six-speed automatic transmission. The same holds true for front-wheel-drive A4 3.2 models. Instead of the automatic, front-drive 2.0T models offer a continuously variable automatic transmission (CVT). Equipped in this configuration, the A4 has a 21 mpg city/29 mpg highway fuel mileage estimate for 2008, which is sure to please if you've got an eye on the pump.
Standard features in this area include antilock brakes, traction control, stability control, front-seat side airbags and full-length side curtain airbags (except on Cabriolets). Rear seat-mounted side airbags are available as an option for the sedan and wagon. In National Highway Transportation Safety Administration frontal crash tests, the A4 rated four stars out of five; in side impact testing, the car earned a perfect five stars for front occupants and four stars for those seated in rear. The 2008 Audi A4 attained a "Good" rating (the highest possible) for the Insurance Institute for Highway Safety's frontal offset, side-impact and head restraint effectiveness tests.
The cherry on top of any Audi vehicle is usually its cabin, and the A4 maintains this standard. Design is above reproach, and build and materials quality is superlative. Some may find the seats overly firm, but most will agree that they provide welcome support when road-tripping. The navigation system takes some getting used to, but elsewhere, the controls are pleasantly intuitive. A4 sedans can haul up to 13.4 cubes of luggage in the trunk, while the Avant manages 27.8 cubes with the rear seats up and 59 cubes with the seats folded. The A4 Cabriolet's traditional soft top might seem a tad old-fashioned in this age of retractable hardtops, but it's reasonably quick in operation and compact enough to allow a maximum luggage capacity of 10.2 cubic feet.
The 2008 Audi A4 is truly a model of composure in the entry-luxury segment, with balanced ride and handling and a suspension that dispenses with ruts and potholes with unflappable German efficiency. As such, it's a sterling daily driver. A4s equipped with the S line Sport Package offer sharper, grippier handling. This Audi is no BMW 3 Series, but it's a more communicative driving partner than many other cars in this class and the extra traction afforded by the Quattro all-wheel-drive system is quite useful in Northern climates. Acceleration is certainly adequate on everything, with the possible exception of the Cabriolet 2.0T. In reviews, we've found the 2.0T a little light on torque down low, but once the tach sees 2,500 rpm, there's plenty of pull on tap. The V6 is smooth, but with only 255 hp, it lacks the motivation needed to keep pace with competitors' 300-plus-hp V6s.
The base 4.2 R8 has a 420 horsepower high-revving V8 engine and all-wheel-drive. It uses the mid-engine Lamborghini Gallardo platform and starts at $114,200, positioning it squarely against the BMW M6, Porsche 911, and Aston Martin Vantage.
The car features a choice of LED or Xenon headlamps surrounded by LED running lights and indicators. LEDs are also used in the engine bay to make the impressive V8 visible even at night.
Both a standard manual and an automated manual transmission are offered. Claimed zero to 62 mph time is 4.6 seconds, though this number is likely conservative.
Interior
The interior has a driver-oriented cockpit architecture, integrating the driver between the dashboard and the high center console. The instrument panel above the console is angled slightly towards the driver. The flat-bottomed steering wheel is a typical feature of the sportiest Audi models, and also enables comfortable sports car entry and exit.
The sports seats are trimmed as standard in a Leather/Alcantara combination, or optionally in full leather. Alternatively, the R8 can also be fitted with bucket seats, specially developed by quattro GmbH. There is plenty of room for the two occupants, with comfort levels well beyond the norm of high-performance sports cars. There is space behind the seats to stow large bags, or even two golf bags. The luggage compartment at the front has a capacity of 100 litres.
With numerous trim variants and applications in Piano finish or Carbon sigma, there are few limits to the range of customization options for the interior.
The drivetrain
At 7,800 rpm the 4.2-liter engine delivers 309 kW (420 bhp) of power output. Peak torque is 430 Newton-meters from 4.500 to 6,000 rpm. And no less than 90 per cent of this maximum torque is maintained consistently throughout a wide engine speed range from 3,500 all the way to 7,600 rpm. As a result of these qualities, the eight-cylinder power unit provides ample thrust in most driving situation.
The engine is a high-revving unit. The maximum engine speed is 8,250 rpm. Two transmissions are available: a manual 6-speed gearbox or optionally the Audi R tronic sequential-shift gearbox, with a joystick gear-shift on the center console and, most especially, the paddles mounted on the steering wheel. 'Shift by wire' technology provides for very fast gear-shifting and an outstanding power-to-weight ratio, allied to compact gearbox dimensions. The Sport mode, with its fast shifting, guarantees the absolute maximum in terms of driving fun. An automatic mode can also be selected.
The car is fitted with permanent four-wheel drive, which distributes the power variably to the front and rear axles by way of a viscous clutch. On the Audi R8 the legendary quattro system is adapted to the axle load distribution typical of mid-engined cars.
The chassis
The chassis features forged aluminum double wishbones at the front and rear. At the front they are triangulated, while at the rear the top one is triangulated and the bottom one is a triangulated wishbone with a track rod. This provides for optimum wheel control, and is a geometry which has proved itself to be the ideal solution in delivering agility, maximum steering precision and precisely defined self-steering characteristics.
Direct, hydraulic rack-and-pinion steering provides optimum feedback to assist the driver.
The spring and damper set-up is stiff in order to deliver maximum driving dynamics, while still providing a quite astonishing level of ride comfort. This is particularly true when the 'Audi magnetic ride' adaptive damper system is chosen as an alternative to the standard gas-filled shock absorbers.
Instead of the conventional damper fluid, a magnetorheological fluid is used -- in other words, a fluid whose viscosity can be influenced by an electromagnetic field. This effect enables the damping characteristic to be influenced electronically at will and instantaneously, by applying a voltage to the electromagnets.
Audi magnetic ride uses this property to deliver the correct damping forces in every driving situation. A computer determines the prevailing driving situation in a matter of milliseconds. Drivers can choose from two driving programs depending on whether they want to drive in a highly sporty style -- with the magnetorheological fluid adjusted to a low viscosity -- or with the emphasis more on ride comfort.
The Audi R8 is fitted with 6-arm 18-inch wheels as standard, and can optionally be ordered with 19-inch wheels. The 235/40 size tires at the front and up to 285/35 at the rear provide the necessary road-holding. The mid-engined sports car's long wheelbase and extremely low center of gravity ensure that it always retains maximum stability.
Equipment and trim
Xenon plus lights, LED rear lights and daytime running lights, 18-inch aluminium wheels, an audio system with 7-inch monitor, an anti-theft alarm and Leather/Alcantara interior trim are just some of the items on the extensive list of standard features.
The range of optional extras includes a Bang & Olufsen sound system, featuring an output of 465 watts and 12 specially designed speakers. A microphone-based vehicle noise compensation system adjusts audio levels to changing road conditions and speeds.
The acoustic parking system and a rear-view camera help the driver to maneuver into even the tightest of spaces. The radio/navigation system plus, featuring a large-format color monitor and MMI keypad, combines extensive functionality with extreme user-friendliness.
A total of eight exterior colors are available, from Ibis White to Phantom Black, pearl effect.
Craftsmanship
The Audi R8 is being built on a small-lot production line in a specially constructed new block at the Audi plant in Neckarsulm. The entire production process -- from the bodyshell construction to final assembly -- is organized in the same way as a craft workshop. Small teams of specialists accompany every step of production, ensuring that every one of the maximum of 15 cars per day built is up to quality standards.
Audi opens up new horizons. The A4 is a sporty car with superb presence on the road; it takes Audi forward into a new dimension on the midsize car market. The engines that power the saloon, both TDI and spark-ignition, in all cases with direct fuel injection, combine effortless power with high efficiency. The dynamic running gear and the use of many technologies taken direct from the large-car category are evidence of the brand’s lead in technical know-how. The new Audi is a new way to drive. It will reach the market at the end of November 2007, at a basic list price of about 26,000 Euros in Germany.
In its design, the new A4 reveals its sporty, progressive character: taut and dynamic in its outlines, it speaks the language of technical perfection. With an overall length of 4.70 metres, the saloon has a substantial, powerful road stance and offers its occupants ample space in an interior full of light. The workmanship is typical of an Audi – quality with no compromises. The controls can be backed by the extra refinement of innovative assistance and multimedia systems. In the safety area, the brand with the four-ring emblem sets new standards: the coordinated action of the airbags and front seat belt force limiters protects the occupants even more effectively.
When compared with the previous model, the A4 has new, sporty proportions. The front body overhang has been drastically shortened; the bonnet and wheelbase are both longer than before. In the driveline, the differential has changed places with the clutch (or torque converter), making it possible to move the front axle forward by 154 millimetres. This innovative solution ensures ideal axle-load distribution. The new A4 is the sportiest saloon in the midsize car category: agile, light and precise to control. Its dynamic suspension is a totally new design, with most of its components made from weight-saving aluminium. The results are impressive: supremely dynamic road behaviour and effortlessly precise handling.
The Audi R8[4] (Typ 42)[6] is a mid-engine, 2-seater sports car,[4][7] which uses Audi's trademark quattro permanent all-wheel drive system.[4][8] It was introduced by the German automaker Audi AG in 2006.
The car was exclusively designed, developed, and manufactured by Audi AG's high performance private subsidiary company, quattro GmbH, and is based on the Lamborghini Gallardo platform.[9] The fundamental construction of the R8 is based on the Audi Space Frame,[4] and uses an aluminium monocoque which is built around space frame principles. The car is built by quattro GmbH in a newly renovated factory at Audi's 'aluminium site' at Neckarsulm in Germany.[4]
In 2005, Audi announced that the name of the successful Audi R8 race car would be used for a new road car in 2007, the Audi R8, based on the Audi Le Mans quattro concept car, appearing at the 2003 International Geneva Motor Show, and 2003 Frankfurt International Motor Show. The R8 road car was officially launched at the Paris Auto Show on 30 September 2006. There was some confusion with the name, which the car shares with the 24 Hours of Le Mans winning R8 Le Mans Prototype (LMP). 6-time 24 Hours of Le Mans winner Jacky Ickx described the R8 as "the best handling road car today".[10] The Audi R8 is used as a safety car in Deutsche Tourenwagen Masters and British Superbike Championship racing series.
The R8 is due to be replaced with a brand new model in calendar year 2014.[11] The highest output version of Audi's new 4.0 liter V8 twin-turbocharged engine is expected to power the new car. This engine is scheduled to be previewed as a detuned version in the 2012 Audi S8—with 518 hp (386 kW) on tap.[citation needed] In the R8 application it is expected to produce about 600 hp.[citation needed] Combined with an approximate 200 lb (91 kg) weight loss, the new R8 is expected to compete well with the new Porsche 997 twin turbo model and will likely perform significantly better than the current R8 GT with a 0–60 mph time in 3.2 seconds and a quarter mile in less than 11 seconds. A dual clutch automated gearbox will be offered for the first time.
The Audi R462956 was initially equipped with a 4.2 litre V8 engine. Specifically, it is an all-aluminium alloy 32-valve (four valves per cylinder) petrol engine,[4] utilising Fuel Stratified Injection (FSI),[4] and has a displacement of 4,163 cubic centimetres (254.0 cu in).[4] It develops a motive power output of 420 metric horsepower (309 kW; 414 bhp) (Directive 80/1269/EEC),[4] and generates 430 newton metres (317 ft·lbf) of torque,[4] on 98 RON 'Super Unleaded' petrol. It is basically the same engine used in the Audi B7 RS4, but is modified to use dry sump lubrication system. This V8 is a highly reworked, high-revving variant of the existing 4.2 litre V8, but includes cylinder-direct fuel injection (Fuel Stratified Injection), and four valves per cylinder, instead of five (as used on the previous non-FSI variants). It also uses two chain-driven double overhead camshafts (DOHC) per cylinder bank, and utilises variable valve timing for both inlet and exhaust camshafts.
The transmission options are either a Lamborghini sourced six-speed manual gearbox with metal gate for the shift lever, or an Audi-developed R tronic[4] gearbox—which is a semi-automatic, without a traditional clutch pedal with automatic gears shifting mode.[7][19] These options are the same as those available on the Lamborghini Gallardo. A double clutch direct-shift gearbox (DSG), now badged by Audi as S tronic, is not available (as of April 2010[update])
AUDI AG unveiled the Audi R8 V10 on 9 December 2008. It uses a 5.2 litre FSI engine,[4] based on the unit in the Lamborghini Gallardo LP560-4 (which in turn was based on the 5.2 FSI V10 as used in the Audi C6 S6 and Audi D3 S8), but is re-tuned to produce a power output of 525 metric horsepower (386 kW; 518 bhp), and generate 530 newton metres (391 ft·lbf) of torque.[4][5] Compared to the V8 variant, the R8 V10's performance numbers are enhanced. Audi states the new 0 to 100 kilometres per hour (0 to 62.1 mph) time as only 3.9 seconds,[4] 60 to 124 miles per hour (97 to 200 km/h) in 8.1 seconds, and a top speed of 317 kilometres per hour (197.0 mph).[4] Other changes to the V10 version of the R8 include some aesthetic differences: such as all-LED headlights (a world-first),[4] interior enhancements such as Bang & Olufsen 465 watt sound system,[4] and a more aggressive body styling,[20] larger rear brakes and unique roadwheels.[4] It was initially thought that this version of the R8 was going to have the same engine as the C6 Audi RS6, a 5.0 litre V10 TFSI twin-turbo engine, which produces 580 metric horsepower (427 kW; 572 bhp). However, some components of the twin-turbo system overheated, and one prototype was destroyed by fire at the Nürburgring.[21] This model was shown at the 2009 North American International Auto Show.

This innovative solution ensures ideal axle-load distribution. The new 2008 Audi A4 is the sportiest saloon in the midsize car category: agile, light and precise to control. Its dynamic suspension is a totally new design, with most of its components made from weight-saving aluminum.
The results are impressive: supremely dynamic road behavior and effortlessly precise handling.
New high-tech options make the 2008 Audi A4 driving experience even more fascinating: Audi drive select varies the engine, automatic transmission, steering and suspension damping characteristics to suit the driver’s preferences at any given moment. Audi dynamic steering varies its ratio according to the car’s speed and keeps the new 2008 Audi A4 stable close to the handling limits by slight, almost instantaneous changes to the steering angle. The damping control system for the hydraulic shock absorbers varies the damping characteristic individually, to combine sporty driving enjoyment with maximum road safety.
The Audi e-tron concept car was unveiled at the 2009 Frankfurt motor show. Similar in appearance to the R8, but slightly smaller, it is powered by four independent electric motors,[24] two mounted within the centre of the front axle and the other two within the rear axle, each produces 79 PS (58 kW; 78 bhp) and 1,125 newton metres (830 ft·lbf) of torque. It produces a total of 317 PS (233 kW; 313 bhp) and a sceptical 4,500 newton metres (3,319 ft·lbf) of torque. However the proposed torque rating is the torque measured at the wheels, not at the output shaft—as is the industry standard, the true torque rating being around 678 newton metres (500 ft·lbf).
The prototype version of the R8 e-tron sticks closely to the original concept with a shape reminiscent of existing V8 and V10 petrol powered versions. Audi claims the production version of the R8 e-tron will be capable of a 0–100 km/h (62 mph) time of around 4.8 seconds, making it only 0.2 seconds slower than the R8 V8. Initial plans call for its top speed to be limited to 124 mph (200 km/h) to protect the charge of the battery. It is planned for launch in early 2012.

The base 4.2 R8 has a 420 horsepower high-revving V8 engine and all-wheel-drive. It uses the mid-engine Lamborghini Gallardo platform and starts at $114,200, positioning it squarely against the BMW M6, Porsche 911, and Aston Martin Vantage.
The car features a choice of LED or Xenon headlamps surrounded by LED running lights and indicators. LEDs are also used in the engine bay to make the impressive V8 visible even at night.
Both a standard manual and an automated manual transmission are offered. Claimed zero to 62 mph time is 4.6 seconds, though this number is likely conservative.
Interior
The interior has a driver-oriented cockpit architecture, integrating the driver between the dashboard and the high center console. The instrument panel above the console is angled slightly towards the driver. The flat-bottomed steering wheel is a typical feature of the sportiest Audi models, and also enables comfortable sports car entry and exit.
The sports seats are trimmed as standard in a Leather/Alcantara combination, or optionally in full leather. Alternatively, the R8 can also be fitted with bucket seats, specially developed by quattro GmbH. There is plenty of room for the two occupants, with comfort levels well beyond the norm of high-performance sports cars. There is space behind the seats to stow large bags, or even two golf bags. The luggage compartment at the front has a capacity of 100 litres.
With numerous trim variants and applications in Piano finish or Carbon sigma, there are few limits to the range of customization options for the interior.
The drivetrain
At 7,800 rpm the 4.2-liter engine delivers 309 kW (420 bhp) of power output. Peak torque is 430 Newton-meters from 4.500 to 6,000 rpm. And no less than 90 per cent of this maximum torque is maintained consistently throughout a wide engine speed range from 3,500 all the way to 7,600 rpm. As a result of these qualities, the eight-cylinder power unit provides ample thrust in most driving situation.
The engine is a high-revving unit. The maximum engine speed is 8,250 rpm. Two transmissions are available: a manual 6-speed gearbox or optionally the Audi R tronic sequential-shift gearbox, with a joystick gear-shift on the center console and, most especially, the paddles mounted on the steering wheel. 'Shift by wire' technology provides for very fast gear-shifting and an outstanding power-to-weight ratio, allied to compact gearbox dimensions. The Sport mode, with its fast shifting, guarantees the absolute maximum in terms of driving fun. An automatic mode can also be selected.
The car is fitted with permanent four-wheel drive, which distributes the power variably to the front and rear axles by way of a viscous clutch. On the Audi R8 the legendary quattro system is adapted to the axle load distribution typical of mid-engined cars.
The chassis
The chassis features forged aluminum double wishbones at the front and rear. At the front they are triangulated, while at the rear the top one is triangulated and the bottom one is a triangulated wishbone with a track rod. This provides for optimum wheel control, and is a geometry which has proved itself to be the ideal solution in delivering agility, maximum steering precision and precisely defined self-steering characteristics.
Direct, hydraulic rack-and-pinion steering provides optimum feedback to assist the driver.
The spring and damper set-up is stiff in order to deliver maximum driving dynamics, while still providing a quite astonishing level of ride comfort. This is particularly true when the 'Audi magnetic ride' adaptive damper system is chosen as an alternative to the standard gas-filled shock absorbers.
Instead of the conventional damper fluid, a magnetorheological fluid is used -- in other words, a fluid whose viscosity can be influenced by an electromagnetic field. This effect enables the damping characteristic to be influenced electronically at will and instantaneously, by applying a voltage to the electromagnets.
Audi magnetic ride uses this property to deliver the correct damping forces in every driving situation. A computer determines the prevailing driving situation in a matter of milliseconds. Drivers can choose from two driving programs depending on whether they want to drive in a highly sporty style -- with the magnetorheological fluid adjusted to a low viscosity -- or with the emphasis more on ride comfort.
The Audi R8 is fitted with 6-arm 18-inch wheels as standard, and can optionally be ordered with 19-inch wheels. The 235/40 size tires at the front and up to 285/35 at the rear provide the necessary road-holding. The mid-engined sports car's long wheelbase and extremely low center of gravity ensure that it always retains maximum stability.
Equipment and trim
Xenon plus lights, LED rear lights and daytime running lights, 18-inch aluminium wheels, an audio system with 7-inch monitor, an anti-theft alarm and Leather/Alcantara interior trim are just some of the items on the extensive list of standard features.
The range of optional extras includes a Bang & Olufsen sound system, featuring an output of 465 watts and 12 specially designed speakers. A microphone-based vehicle noise compensation system adjusts audio levels to changing road conditions and speeds.
The acoustic parking system and a rear-view camera help the driver to maneuver into even the tightest of spaces. The radio/navigation system plus, featuring a large-format color monitor and MMI keypad, combines extensive functionality with extreme user-friendliness.
A total of eight exterior colors are available, from Ibis White to Phantom Black, pearl effect.
Craftsmanship
The Audi R8 is being built on a small-lot production line in a specially constructed new block at the Audi plant in Neckarsulm. The entire production process -- from the bodyshell construction to final assembly -- is organized in the same way as a craft workshop. Small teams of specialists accompany every step of production, ensuring that every one of the maximum of 15 cars per day built is up to quality standards.
Audi opens up new horizons. The A4 is a sporty car with superb presence on the road; it takes Audi forward into a new dimension on the midsize car market. The engines that power the saloon, both TDI and spark-ignition, in all cases with direct fuel injection, combine effortless power with high efficiency. The dynamic running gear and the use of many technologies taken direct from the large-car category are evidence of the brand’s lead in technical know-how. The new Audi is a new way to drive. It will reach the market at the end of November 2007, at a basic list price of about 26,000 Euros in Germany.
In its design, the new A4 reveals its sporty, progressive character: taut and dynamic in its outlines, it speaks the language of technical perfection. With an overall length of 4.70 metres, the saloon has a substantial, powerful road stance and offers its occupants ample space in an interior full of light. The workmanship is typical of an Audi – quality with no compromises. The controls can be backed by the extra refinement of innovative assistance and multimedia systems. In the safety area, the brand with the four-ring emblem sets new standards: the coordinated action of the airbags and front seat belt force limiters protects the occupants even more effectively.
When compared with the previous model, the A4 has new, sporty proportions. The front body overhang has been drastically shortened; the bonnet and wheelbase are both longer than before. In the driveline, the differential has changed places with the clutch (or torque converter), making it possible to move the front axle forward by 154 millimetres. This innovative solution ensures ideal axle-load distribution. The new A4 is the sportiest saloon in the midsize car category: agile, light and precise to control. Its dynamic suspension is a totally new design, with most of its components made from weight-saving aluminium. The results are impressive: supremely dynamic road behaviour and effortlessly precise handling.
The Audi R8[4] (Typ 42)[6] is a mid-engine, 2-seater sports car,[4][7] which uses Audi's trademark quattro permanent all-wheel drive system.[4][8] It was introduced by the German automaker Audi AG in 2006.
The car was exclusively designed, developed, and manufactured by Audi AG's high performance private subsidiary company, quattro GmbH, and is based on the Lamborghini Gallardo platform.[9] The fundamental construction of the R8 is based on the Audi Space Frame,[4] and uses an aluminium monocoque which is built around space frame principles. The car is built by quattro GmbH in a newly renovated factory at Audi's 'aluminium site' at Neckarsulm in Germany.[4]
In 2005, Audi announced that the name of the successful Audi R8 race car would be used for a new road car in 2007, the Audi R8, based on the Audi Le Mans quattro concept car, appearing at the 2003 International Geneva Motor Show, and 2003 Frankfurt International Motor Show. The R8 road car was officially launched at the Paris Auto Show on 30 September 2006. There was some confusion with the name, which the car shares with the 24 Hours of Le Mans winning R8 Le Mans Prototype (LMP). 6-time 24 Hours of Le Mans winner Jacky Ickx described the R8 as "the best handling road car today".[10] The Audi R8 is used as a safety car in Deutsche Tourenwagen Masters and British Superbike Championship racing series.
The R8 is due to be replaced with a brand new model in calendar year 2014.[11] The highest output version of Audi's new 4.0 liter V8 twin-turbocharged engine is expected to power the new car. This engine is scheduled to be previewed as a detuned version in the 2012 Audi S8—with 518 hp (386 kW) on tap.[citation needed] In the R8 application it is expected to produce about 600 hp.[citation needed] Combined with an approximate 200 lb (91 kg) weight loss, the new R8 is expected to compete well with the new Porsche 997 twin turbo model and will likely perform significantly better than the current R8 GT with a 0–60 mph time in 3.2 seconds and a quarter mile in less than 11 seconds. A dual clutch automated gearbox will be offered for the first time.
The Audi R462956 was initially equipped with a 4.2 litre V8 engine. Specifically, it is an all-aluminium alloy 32-valve (four valves per cylinder) petrol engine,[4] utilising Fuel Stratified Injection (FSI),[4] and has a displacement of 4,163 cubic centimetres (254.0 cu in).[4] It develops a motive power output of 420 metric horsepower (309 kW; 414 bhp) (Directive 80/1269/EEC),[4] and generates 430 newton metres (317 ft·lbf) of torque,[4] on 98 RON 'Super Unleaded' petrol. It is basically the same engine used in the Audi B7 RS4, but is modified to use dry sump lubrication system. This V8 is a highly reworked, high-revving variant of the existing 4.2 litre V8, but includes cylinder-direct fuel injection (Fuel Stratified Injection), and four valves per cylinder, instead of five (as used on the previous non-FSI variants). It also uses two chain-driven double overhead camshafts (DOHC) per cylinder bank, and utilises variable valve timing for both inlet and exhaust camshafts.
The transmission options are either a Lamborghini sourced six-speed manual gearbox with metal gate for the shift lever, or an Audi-developed R tronic[4] gearbox—which is a semi-automatic, without a traditional clutch pedal with automatic gears shifting mode.[7][19] These options are the same as those available on the Lamborghini Gallardo. A double clutch direct-shift gearbox (DSG), now badged by Audi as S tronic, is not available (as of April 2010[update])
AUDI AG unveiled the Audi R8 V10 on 9 December 2008. It uses a 5.2 litre FSI engine,[4] based on the unit in the Lamborghini Gallardo LP560-4 (which in turn was based on the 5.2 FSI V10 as used in the Audi C6 S6 and Audi D3 S8), but is re-tuned to produce a power output of 525 metric horsepower (386 kW; 518 bhp), and generate 530 newton metres (391 ft·lbf) of torque.[4][5] Compared to the V8 variant, the R8 V10's performance numbers are enhanced. Audi states the new 0 to 100 kilometres per hour (0 to 62.1 mph) time as only 3.9 seconds,[4] 60 to 124 miles per hour (97 to 200 km/h) in 8.1 seconds, and a top speed of 317 kilometres per hour (197.0 mph).[4] Other changes to the V10 version of the R8 include some aesthetic differences: such as all-LED headlights (a world-first),[4] interior enhancements such as Bang & Olufsen 465 watt sound system,[4] and a more aggressive body styling,[20] larger rear brakes and unique roadwheels.[4] It was initially thought that this version of the R8 was going to have the same engine as the C6 Audi RS6, a 5.0 litre V10 TFSI twin-turbo engine, which produces 580 metric horsepower (427 kW; 572 bhp). However, some components of the twin-turbo system overheated, and one prototype was destroyed by fire at the Nürburgring.[21] This model was shown at the 2009 North American International Auto Show.

When compared with the previous model, the 2008 Audi A4 has new, sporty proportions. The front body overhang has been drastically shortened; the bonnet and wheelbase are both
longer than before. In the driveline, the differential has changed places with the clutch (or torque converter), making it possible to move the front axle forward by 6.1 inches. This innovative solution ensures ideal axle-load distribution. The new 2008 Audi A4 is the sportiest saloon in the midsize car category: agile, light and precise to control. Its dynamic suspension is a totally new design, with most of its components made from weight-saving aluminum.
The results are impressive: supremely dynamic road behavior and effortlessly precise handling.
New high-tech options make the 2008 Audi A4 driving experience even more fascinating: Audi drive select varies the engine, automatic transmission, steering and suspension damping characteristics to suit the driver’s preferences at any given moment. Audi dynamic steering varies its ratio according to the car’s speed and keeps the new 2008 Audi A4 stable close to the handling limits by slight, almost instantaneous changes to the steering angle. The damping control system for the hydraulic shock absorbers varies the damping characteristic individually, to combine sporty driving enjoyment with maximum road safety.
The Audi e-tron concept car was unveiled at the 2009 Frankfurt motor show. Similar in appearance to the R8, but slightly smaller, it is powered by four independent electric motors,[24] two mounted within the centre of the front axle and the other two within the rear axle, each produces 79 PS (58 kW; 78 bhp) and 1,125 newton metres (830 ft·lbf) of torque. It produces a total of 317 PS (233 kW; 313 bhp) and a sceptical 4,500 newton metres (3,319 ft·lbf) of torque. However the proposed torque rating is the torque measured at the wheels, not at the output shaft—as is the industry standard, the true torque rating being around 678 newton metres (500 ft·lbf).
The prototype version of the R8 e-tron sticks closely to the original concept with a shape reminiscent of existing V8 and V10 petrol powered versions. Audi claims the production version of the R8 e-tron will be capable of a 0–100 km/h (62 mph) time of around 4.8 seconds, making it only 0.2 seconds slower than the R8 V8. Initial plans call for its top speed to be limited to 124 mph (200 km/h) to protect the charge of the battery. It is planned for launch in early 2012.
