Audi R8 race car to tackle Nürburgring 24 hrs

his year's Nürburgring 24-hour endurance race will feature perhaps the most wicked Audi R8 yet: a lightweight, custom-built racer that makes the road car look tame by comparison. To comply with the requirements for participation in the race, the stock 4.2L V8 donates its block and is rebuilt from there. The race-spec motor's displacement drops to 4.0 liters but it delivers a hefty 530 horsepower and 353 lb-ft of torque. The R8's stock front and rear bodywork is replaced by new, widebody carbon kevlar panels. Those outboard intakes in the nose are replaced by blanks, and out back, the custom exhaust's dual outlets poke through the spot where the license plate would reside on the production car. Other obvious additions are the front splitter, large rear wing, rear diffuser, and multiple cutouts in the aft bodywork to help with engine cooling. The entire package weighs in at just 2,755 pounds -- this thing should absolutely haul. German magazine Sport-Auto has been covering the car's development. We'll see how the car fares in competition next week.
