Detroit 2008: Audi unleashes its diesel monster, the R8 V12 TDI

Today Audi brought some more of its Le Mans-conquering technology to the street in the form of the new R8 V-12 TDI. The R8 V12 TDI is a concept that melds the 6.0L V-12 diesel from last years Q7 concept with the award winning R8 sports car. The concept engine shares a cylinder count with the race-winning R10, but it’s actually a completely new engine with a 60-degree bank angle instead of the 90 degrees used on the race engine. While the 500 hp is only par for the course in its class, the 738 lb-ft of torque is enough to shred all four tires with ease. While the R8 V12 TDI storms to 62mph in 4.2 seconds and maxes out at 186mph, it also manages to get 23 MPG. The combination of a 29,000-psi direct-inject fuel injection system, particulate filters and urea injection allows this beast to pass 2014 EuroVI emissions standards, too.
