What is the difference between the horsepower at the flywheel and at the wheels?
At the flywheel horsepower is always higher than the wheel horsepower. When the power is being transferred from the engine to the wheels, so of the power gets wasted in the drivetrain moving parts, such as the transmission and differentials. So, the wheel horsepower is the power that actually made it to the wheels. Remember, AWD cars have a higher horsepower loss in the drivetrain than the FWD or RWD car. AT transmissions loose more horsepower than the manual transmissions due to the increased number of moving parts.
