Three years after unveiling the Audi Le Mans quattro concept car, Audi unveiled the production version of the mid-engined 2-seat supercar at the 2006 Paris Motor Show.

Named after one of the most storied race cars in Le Mans history, the R8 is powered by a 420-hp V8 with direct fuel injection and mounted behind the cockpit and ahead of the rear wheels. The engine is visible through the clear canopy that doubles as a rear window. Behind the doors, air deflectors deliver air to feed and cool the V8.

The body of the production car is the latest iteration of the aluminum Audi Space Frame and the drivetrain is the latest version of Audi's famed quattro permanent 4-wheel drive.

The central position of the engine grants the R8 nearly ideal weight distribution (44 percent front, 56 percent rear). The cabin moved far forward instantly marks the car as a mid-engined 2-seater as well as tying it to the full-bodied Le Mans cars of old.

The front end features Audi's trapezoidal grille, flanked by additional large-dimensioned air intakes below the narrow headlights (all lamps are LEDs). For the first time, Audi's four-ring badge is positioned on the bonnet, not on the grille.

The headlights use a design reminiscent of an open pine cone with reflector shells arranged concentrically one behind the other. This concentrates the light from one multi-chip LED, producing a high-luminosity beam. The rear lights are also LEDs, as is the third brake light strip that runs the full width of the roof above the engine cover. Optionally, the engine compartment can also be lit by LEDs so the engine can be seen in the dark.

The sporty interior is dominated by a totally driver-oriented cockpit design that wraps around the driver. The instrument panel above the console is angled slightly towards the driver and the flat-bottomed steering wheel allows easy entry and exit.

The sports seats are a standard Leather/Alcantara combination or the grippy suede-like Alcantara can be replaced by more leather. Sport bucket seats, specially developed by quattro GmbH, are optional. There are also customization options for the interior (including Piano finish or Carbon sigma)

Audi claims enough space in the R8 to stow two golf bags behind the seats. The luggage compartment at the front of the car has a capacity of 100 litres.

Redlined at 8,250 rpm, the high-revving V8's 420 hp peak at 7,800 rpm, while max torque of 317 lbs.ft peaks between 4,500 and 6,000 rpm. Ninety percent of torque is available between 3,500 and 7,600 rpm for maximum thrust almost from a stand still. Audi claims acceleration from a standstill to 100 km/h in 4.6 seconds on its way to a top speed of 301 km/h.

Two transmissions are available: a standard 6-speed manual or optionally the Audi R tronic sequential-shift gearbox controlled by steering wheel paddles. As in the RS4 introduced in 2006, a Sport mode grants sportier shift patterns and better throttle response.

The chassis features forged aluminium double wishbones front and rear. The spring and damper set-up is stiff in order to deliver maximum driving dynamics, while still maintaining some semblance of ride comfort. The driver selectable 'Audi magnetic ride' adaptive damper system is optional to the standard gas-filled shocks.

The Audi R8 rides on 18-inch wheels (optional 19-inchers) shod with 235/40 size tires up front and 285/35s at the rear. The car's extremely low centre of gravity ensures maximum stability.

For safety, a parking assist system uses a rear-view camera and audible warnings to help the driver manoeuvre the R8 into the tightest of spaces.

Customers will be able to start placing orders immediately for delivery in the first half of 2007.
