Divide the engine torque by the drivetrain loss factor to determine the wheel torque.
The Wheel Torque Calculator is an essential tool for automotive enthusiasts and engineers to evaluate the torque delivered to a vehicle’s wheels. Wheel torque is critical for understanding a car’s performance, including acceleration, towing capacity, and off-road capabilities.
This calculator helps you account for drivetrain losses, making it perfect for scenarios involving engine modifications, gear ratio adjustments, or vehicle tuning. Whether you’re working with motorcycles, cars, or heavy machinery, accurate torque calculations ensure optimal performance.
Formula
WT = ET / DL
| Variable | Definition |
|---|---|
| WT | Wheel Torque (lb-ft) |
| ET | Engine Torque (lb-ft) |
| DL | Drivetrain Loss Factor (%) |
Solved Calculations
Example 1: For a car with 300 lb-ft of engine torque and a drivetrain loss of 15%:
| Variable | Value |
|---|---|
| Engine Torque (ET) | 300 lb-ft |
| Drivetrain Loss (DL) | 0.15 |
| Wheel Torque (WT) | 352.94 lb-ft |
Example 2: For a motorcycle with 100 lb-ft of engine torque and a drivetrain loss of 10%:
| Variable | Value |
|---|---|
| Engine Torque (ET) | 100 lb-ft |
| Drivetrain Loss (DL) | 0.10 |
| Wheel Torque (WT) | 111.11 lb-ft |
