Key Differences Between Understeer and Oversteer

At Mercedes-Benz of Plano, we like to provide drivers with useful automotive information that helps them keep their vehicles safe and in good condition. Oversteer and understeer are related to your vehicle's dynamics. While oversteer and understeer can occur in front-wheel and rear-wheel drive automobiles, oversteer is more common in rear-wheel drive vehicles, and understeer is more likely to happen in front-wheel drive vehicles.

When understeer occurs, the steering wheel won't be responsive. When you try to turn, the wheels may continue to plow straight. This typically happens when you start to speed up too quickly when you're approaching a turn, and it can happen if you turn the wheels too fast or too hard. One way to correct understeer is to apply additional suspension, and it can also be helpful to have a tire pressure adjustment.

With oversteer, the vehicle will slide out and fishtail because the rear loses traction. If this occurs, you may need to loosen the suspension and drop the grip.
