Power to Weight Calculator
Calculate your vehicle’s power-to-weight ratio to determine performance potential. This key metric helps compare vehicles of different sizes and engine configurations.
Step 1: Vehicle Weight
Understanding Vehicle Weight
For accurate power-to-weight calculations, use the vehicle’s curb weight (empty weight with all fluids). Add passenger and cargo weight for real-world performance estimates.
Step 2: Engine Power
About Drivetrain Loss
Drivetrain loss accounts for power lost between the engine and wheels. Front-wheel drive: 10-15%, rear-wheel drive: 15-20%, all-wheel drive: 20-25%. This gives you a more realistic wheel horsepower figure.

Power-to-Weight Formula
Power-to-Weight Ratio = (Engine Power × (1 – Drivetrain Loss)) / Total Vehicle Weight
To calculate power-to-weight ratio: Multiply engine power by (1 minus drivetrain loss percentage) to get wheel power, then divide by total vehicle weight (including passengers and cargo).
