A drivetrain loss calculator is a tool used to estimate the amount of power lost between an engine and the wheels of a vehicle. The calculations are based on various factors, including the type of transmission, drivetrain layout, and tire size. A drivetrain loss calculator is a useful tool for understanding the amount of power that is actually being delivered to the wheels of a vehicle, which can help in tuning the vehicle for maximum performance or estimating fuel economy.

Forumla for Caluclating the Drivetrain Loss
The formula for calculating drivetrain loss is:
Drivetrain Loss = (1 – (Wheel Horsepower / Engine Horsepower)) x 100
- Wheel Horsepower: Amount of power that is actually delivered to the wheels of the vehicle
- Engine Horsepower: Amount of power produced by the engine
To use this formula, you will need to know the engine horsepower and wheel horsepower. Wheel horsepower is the amount of power that is actually delivered to the wheels of the vehicle, while engine horsepower is the amount of power produced by the engine.
To calculate engine horsepower, you can use a dynamometer, which is a tool that measures the power output of an engine. To calculate wheel horsepower, you can use a chassis dynamometer, which measures the power output of the wheels.
Example
Once you have both of these values, you can plug them into the formula above to calculate the drivetrain loss. For example, if the engine produces 300 horsepower and the wheels produce 250 horsepower, the drivetrain loss would be:
Drivetrain Loss = (1 – (250 / 300)) x 100 Drivetrain Loss = 16.67%
This means that 16.67% of the power produced by the engine is lost between the engine and the wheels.
