About this calculator
Overview
The center of mass (CoM) or center of gravity (CoG) is a crucial point for vehicle handling, braking, and stability. This calculator finds the horizontal position of the CoM.
💡
Pro Tips
A 50/50 weight distribution is often considered ideal for balanced handling.
Front-wheel drive cars typically have more weight over the front axle (~60/40).
Moving the center of mass lower (e.g., by placing batteries low in an EV) improves cornering stability.

Fun Facts
"The 'height' of the center of mass also affects body roll, but requires tilting the car to measure properly."
"Race cars are weighed on four individual scales to fine-tune the 'cross-weight' for specific tracks."
"In a Porsche 911, the center of mass is biased toward the rear due to the engine placement."
