HP to WHP formula
You can use the following formula for horsepower (hp) to wheel horsepower (whp)
WHP = HP * (1 – DL/100)
- WHP = wheel horsepower
- HP = horsepower
- DL = drivetrain loss
Drivetrain loss based on selected type
| Drivetrain type | drive loss percentage |
|---|---|
| Front-wheel drive | 10% |
| Rear-wheel drive | 15% |
| All-wheel drive | 25% |
How to calculate hp to whp?
To convert horsepower (hp) to wheel horsepower (whp), you can use a conversion factor that takes into account the drivetrain losses.
For example – you have a car with 280 horsepower and a drivetrain loss of 15% then calculate power in wheel horsepower(whp)
whp = 280 hp x (1 – 0.15)
whp = 280 hp x 0.85
whp = 238
the wheel horsepower of the car for a 15% drivetrain loss, would be 238 whp
