Project Kahn decided the to leave the Audi R8’s engine alone in its latest customization. It seems the British folks decided that 414 hp, 4.2-liter V8 was already enough for the car.
What they decided was the German lacked style. The tuning house added a new set of 20-inch F1-X carbon-fiber rims as well as a new suspension kit. Also the British tuner can customize the interior in every way the customer may want; just like the Aston Martin Vanquish S.
