What is the formula of whp to hp?

The formula for converting wheel horsepower (WHP) to horsepower (HP) is straightforward. Since wheel horsepower refers to the amount of power actually measured at the wheels of a vehicle, it takes into account any power losses that may occur in the drivetrain

HP = WHP / (1 – DL/100)

  • HP = horsepower
  • WHP = wheel horsepower
  • DL = drivetrain loss

Drivetrain loss based on selected type

Drivetrain typedrive loss percentage
Front-wheel drive10%
Rear-wheel drive15%
All-wheel drive25%

How to calculate whp to hp?

To convert wheel horsepower (WHP) to horsepower (HP), you need to know the drivetrain efficiency. The drivetrain efficiency represents the power losses between the engine and the wheels.

For example – if a car has a wheel horsepower of 2800 and a drive train loss factor of 10%, then calculate the engine horsepower.

Given, wheel horsepower = 2800 and drivetrain loss factor = 10%

Engine Horsepower = whp/(1 – dl) = 2800 / (1 – 0.1) = 280 / 0.9 = 311.11 hp
