Audi's Diesel Insanity
The engine in the Audi R10 Le Mans car is a 12 cylinder, turbocharged, all aluminium, diesel engine. It produces 650 horsepower and about 810 ft-lbs of torque, and its making history at the Le Mans races. I'm actually surprised that Mercedes Benz didn't come up with this first. I'm sure Audi could take their crazy new engine, take the horsepower down a few notches to about 350-400 hp, and put it in the A10 or S10 for a really sick high end performance diesel luxury.
