Wheel Horsepower Calculator

Formula

The formula to calculate the Wheel Horsepower (WHP) is:

\[ WHP = \frac{EHP}{DTLF} \]

Where:

\(WHP\) is the wheel horsepower
\(EHP\) is the engine horsepower
\(DTLF\) is the drive train loss factor

Wheel Horsepower Definition

Wheel horsepower is a measure of the horsepower delivered to the wheels of a car by the engine after the drivetrain loss has been taken into account. The drive train loss is a loss of power that the wheels receive due to friction and other inefficiencies through the drive train.

Example Calculation

Let's assume the following values:

Engine Horsepower (EHP) = 300
Drive Train Loss Factor (DTLF) = 1.15 (Rear Wheel Drive)

Using the formula to calculate the Wheel Horsepower (WHP):

\[ WHP = \frac{300}{1.15} \approx 260.8696 \]

The Wheel Horsepower (WHP) is approximately 260.8696.
