The diesel powered R8 is expected to be a concept, but according to rumors the car is already planned for production. The V12 engine will produce around 500 horsepower and 738 lb-ft of torque while getting 28mpg. The engine is the same engine that is going to be offered in the Q7 SUV later this year.
