Wheel Horsepower Calculator

Convert crank HP to wheel HP.

Wheel horsepower (whp) 255

Step-by-step with your numbers:

1. Values used:

2. Crank horsepower = 300 hp

3. Drivetrain loss = 15 %

4. Wheel horsepower = 255whp

Did we solve your problem today?

Crank HP minus drivetrain losses gives wheel HP.

The math behind it

WHP = crank HP × (1 − drivetrain loss %). Typical loss: 10–20%.

Manual vs auto?

Manual ~10–15% loss; automatic ~15–20%.
