Vehicle Speed Calculator

The Vehicle Speed Calculator determines vehicle speed based on gear ratio, RPM, and tire diameter. By inputting the known values, the calculator finds the missing parameter. Understanding vehicle speed is crucial for optimizing performance, fuel efficiency, and drivability.

Accurate vehicle speed calculations help you fine-tune your vehicle's setup, ensuring that it performs optimally under different driving conditions. This tool is valuable for performance tuning, helping to balance speed, acceleration, and fuel consumption to meet your driving needs.

For vehicle speed, the formula involves multiplying the engine RPM by the tire diameter and then dividing by the product of the gear ratio, the constant 336, and the transmission gear ratio.
