A device called a Dynomometer (rolling road) is connected to the automobile wheels.

The engine is run at full throttle from idle to maximum RPM, then the engine is disconnected from the wheels (neutral) and the wheels allowed to slow down through the speed range.

A computer then calculates the engine torque and Horse Power.
