2007 Audi R8
(from Audi Press Release) Audi R8
Audi has incorporated the name and the genes of the five-time Le Mans winner, the Audi R8, into a spectacular sports car. Three years after the unveiling of the Audi Le Mans quattro concept car, the production version will be making its debut at the Paris Motor Show in the guise of the new Audi R8 mid-engined sports model.
It is a fascinating driving machine and the sporty pinnacle of the Audi brand. The mid-mounted 420 bhp V8 FSI engine, quattro permanent four-wheel drive and Audi Space Frame aluminium body form the basis for truly outstanding driving dynamics. The Audi R8 will be available to order from 28 September 2006; first deliveries will be made in the first half of 2007.
The exterior
Even at first glance, the calibre of the car is plain to see. The Audi R8 sits broad and squat on the road, the strongly accentuated rear end appearing to flex its muscles like a sprinter ready for the off.
The characteristic proportions of the vehicle are dictated by the location of the engine behind the cockpit. This layout is a typical feature of race cars. One of the most striking examples of this design – and as such one of the legitimate antecedents of the Audi R8 – was, and still is, the Auto Union Type C Grand Prix car. The central position of the engine is above all a boon to driving dynamics, as it allows for a weight distribution, as on the R8, of 44 percent to the front and 56 percent to the rear.
The car's body is highly compact in appearance. The front end and the gently curved roof arc are drawn in a sweeping line; a line which immediately marks the two-seater out as an Audi.
The interior
The sporty interior is dominated by a totally driver-oriented cockpit architecture, integrating the driver between the dashboard and the high centre 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.
Form follows function: this design principle is implemented throughout the Audi R8. Alongside the driver-oriented architecture, also reflected in the styling of the side window sills, the choice of materials also makes for a highly functional look and feel. Looking around when in the driving seat makes one thing clear: just like in the R8 race car, the styling and placement of all the elements in the cockpit of this driving machine is focussed on the essentials. The centrepoint of everything is the driver.
The drive train
Turbine-like power up to the highest rev ranges, a high maximum torque, all combined with a fascinating sound, are the characteristics of a perfect sports car engine. An engine that is fascinating both in terms of its enormous power potential and its suitability for everyday use.
In the high-revving 420 bhp eight-cylinder engine, the evolution of FSI petrol direct injection technology has reached a new high. This technology has also enjoyed many triumphs in the Audi R8 race car.
The figures illustrate the outstanding potential of the eight-cylinder unit. At 7,800 rpm the 4.2-litre engine delivers 309 kW (420 bhp) of power output. Peak torque is 430 Newton-metres 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 maximum thrust in virtually any driving situation.
The performance figures are equally impressive: the R8 accelerates from a standstill to 100 km/h in 4.6 seconds and reaches a top speed of 301 km/h.
The engine is a high-revving unit. The maximum engine speed is 8,250 rpm. The advantages of this principle are superior power output at high engine speeds and a smooth, eager responsiveness all across the revs range. Added to this are its agility, liveliness and engine sound, which is similar to that of a race car.
The chassis
The chassis features forged aluminium 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.
The reason for this is that these shock absorbers employ an innovative technology. 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.
Equipment and trim
Even the standard equipment of the Audi R8 meets the high demands of customers in this segment. 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 leaves virtually nothing to be desired. A Bang & Olufsen sound system, featuring an output of 465 watts and 12 specially designed speakers, delivers surround sound of the highest standard. 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 manoeuvre into even the tightest of spaces. The radio/navigation system plus, featuring a large-format colour monitor and MMI keypad, combines extensive functionality with extreme user-friendliness.
A range of coordinated and ideally combinable design and leather trim packages from Audi and from quattro GmbH can turn any R8 into the customer’s personal dream car.
The wheels range offers design alternatives in sizes of 18 and 19 inches, fitted with 235/35 size tyres at the front and up to 295/30 at the rear. A total of eight exterior colours are available, from Ibis White to Phantom Black, pearl effect.
The 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 organised in the same way as a craft workshop. Small teams of specialists accompany every step of production, subjecting every part and component to intense scrutiny. This ensures that every one of the maximum of 15 cars per day built will more than match the customary high quality standards of the Audi product range.
