Weight Distribution

Weight distribution is how a car’s mass is split between the front and rear axles, often shown as a percentage such as 50:50.

What is Weight Distribution?

Front-engine, front-wheel-drive cars usually carry more weight at the front. Mid- and rear-engine cars have more weight at the back. Passengers, luggage and fuel change the distribution. Moving the battery to the boot is a classic way to shift weight rearwards on modified cars.

How it works

The load on each axle affects how much grip the tyres can provide when braking, cornering and accelerating.

Why it matters for your car

Nose-heavy cars tend to understeer; tail-heavy cars can oversteer suddenly. Heavy loads in the boot or on a tow bar change handling and braking.
