Audi R8 V12 TDI Le Mans

Audi R8 V12 TDI Le Mans

2008 Audi R8 V12 TDI Le Mans Review. The R8 consists of a twin turbo diesel V12 engine with a capacity of 5934 cc. The bore measures 83 mm and the stroke measures 91.4mm. The engine delivers an output power of 500 bhp and 738 lb-ft torque at 1750 rpm. It reaches the speed of 60 mph in 4.2 sec and the top speed is 186 mph. The car features six speed manual transmission and the gear shifts can be performed easily even at higher loads.

Power for the concept comes from the automakers race-derived 6.0 liter V12 diesel motor, which was first used in the R10 Le Mans competition car, and is now available in the Audi Q7. The engine produces 500 horsepower and 738 pound-feet of torque. The peak torque, reached at only 1,750 rpm.
The car sprints to 62 mph in 4.2 seconds, according to Audi. Like most German automakers, Audi is probably reporting a very conservative acceleration time for this car.

The interior’s design is as sporty and exclusive as the exterior: the characteristic element here is the monoposto – an expansive arc running around the steering wheel and instruments, connecting the driver to the car. The interior consequently picks up on the dynamism of the R8 TDI Le Mans and gives it tactile expression in a form that is accessible the moment you climb in.
The three-spoke sport steering wheel of course remains the focal point of the car’s controls. With a diameter of 365 mm (14.37 in.), it is both sportily compact and ergonomic in shape. The steering wheel rim has a flat lower edge. This is a further aspect of the auto racing feel in the Audi R8 TDI Le Mans, but one that also brings major functional benefits, facilitating entry and exit for the driver. The steering wheel is covered in fine Valcona leather, with a diecast magnesium core providing strength.
The start/stop button for the engine and the Drive Select switch with the Dynamic/ Sport/Race settings are arranged on the steering wheel. The latter controls the engine and transmission electronics as well as the magnetic ride dampeners in each of three different modes.
In Race mode, the instrument lighting changes from white to red. The navigation system shows a combined display with lap timer and navigation information for the racetrack being driven. Or supplementary information such as centrifugal force and boost pressure can be called up.
The ceramic brakes are identifiable at a glance by the special red, six-piston monobloc aluminum calipers and the fixed calipers at the rear. The advantages of the ceramic brakes include a further reduction in weight of around 20 kilograms (44.09 lbs.), which in this case improves the handling characteristics and comfort. The high abrasion resistance permits an operating life of up to 300,000 kilometers (186,411 miles). Their key strength, however, is their ability to withstand very high loads. Even on the racetrack, for example, the ceramic brakes always maintain their full reserve performance.
