WHP to HP Calculator

Wheel Horsepower Formula

A car's horsepower is calculated using the following formula.

WHP = EHP / DTLF
  • Where WHP represents a wheel horsepower
  • EHP stands for engine horsepower
  • LF is the drive train loss factor
    • front wheel drive = 1.1
    • rear wheel drive = 1.15
    • all wheel drive = 1.2

Wheel horsepower

The horsepower that a car's engine delivers to the wheels after accounting for drivetrain loss is known as wheel horsepower.
