Dyno machines are used to determine the maximum horsepower and torque a car is pushing when at full tilt. It is meant to help tune the car and stroke the ego of the car owner, particularly if they owned this car, the all new Audi R8 V10. In this clip, there are NO horsepower OR torque numbers. Just the sweet, sweet sound of all ten of those cylinders belching carbon monoxide and exhaust fumes. Oh how I love the symphony of power and engineering. Enjoy.
