This calculator was developed to estimate the vehicle's maximum speed and available wheel torque based on technical parameters of the drive system. By entering values ​​such as engine speed (RPM), maximum torque, transmission ratio, and tire diameter, it is possible to visualize in a practical way how these variables influence the final performance of the system, assisting in the sizing, comparison of configurations, and technical validation of electric mobility projects and experimental applications.

Vehicle Speed Calculator

Estimate the maximum speed and torque at the wheel from the RPM, engine torque, gear ratio, and tire diameter.

Maximum speed — km/h
Wheel torque — N·m
These are just estimates. Actual results will vary depending on tire geometry, road conditions, air resistance, friction, and measurement method.
