German carmaker Audi developed the first 12-cylinder diesel engine in a high performance road going sports car. With a displacement of six liters it powers a concept car based on the Audi R8. It has 500 horsepower and 1.000 Nm of torque as output. The V12 TDI is related to the engine in the Audi R10, the two-time Le Mans winner so it sends the Audi R8 into supercar terrain concerning performance too. The output enables the car to accelerate from 0 to 60 mph in 4.2 seconds and to reach a top speed of 186 mph. The engine is full-bodied and equipped with energetic overtones that make no secret of its performance potential. The V12 TDI race engine in the R10 produces over 650 horsepower from a displacement of 5.5 liters, giving it the potential for a top speed as high a 330 km/h depending on the gear ratios. Two large intercoolers reduce the temperature of the compressed air. The V12 has a twin-pipe exhaust system with two particulate filters. The intake system is similar in structure with one air cleaner per cylinder bank, with an airflow meter behind it. The Audi R8 TDI Le Mans already fulfills the Euro 6 emissions standard that is likely to take effect in 2014 and calls for sharply reduced nitrogen oxides. The dynamic character of a sports car depends not just on its performance and torque, but the transmission ratios have to be right too. The manual transmission is very compact in design; has very short shift travel and utterly precise guiding of the shifter into the open gear lever gate. The engine can also be seen after dark, when white light-emitting diodes illuminate the compartment of the engine as on the production version of the Audi R8. The design of the interior is as sporty and exclusive as the exterior.
