What is the difference between oversteering and understeering?
Understeer and oversteer are vehicle dynamics terms used to describe the sensitivity of a vehicle to steering. Oversteer is what occurs when a car turns (steers) by more than the amount commanded by the driver. Conversely, understeer is what occurs when a car steers less than the amount commanded by the driver.
What is understeering and oversteering in car?
Oversteering and understeering are practical terms that are used to describe the automobile sensitivity to steering. Oversteering occurs when the car turns more than how the driver has commanded while understeering is turning less below what the driver controls.
How do you fix oversteering and understeering?
The driving technique to reduce understeer is to let off the throttle to reduce speed and allow the front tyres to re-gain traction. To correct oversteer you should counter steer to prevent the car from spinning, and then reduce the amount of throttle enough to allow the car to begin straightening.
What causes understeering and oversteering?
Understeering occurs in vehicles with front-wheel drive and usually happens when the driver is going too fast for conditions, which causes the front tires to lose their grip on the road. Oversteering is something that happens in vehicles that have rear-wheel drive, and it also is related to speed.
What causes understeering?
What causes understeer? Understeer happens as a direct result of driver input. Turning the steering wheel harshly, abruptly or just too much for the vehicle’s speed versus the available grip will exceed the front tyres’ traction, forcing the nose of the car to slide wide across the road surface in understeer.
What oversteer means?
Definition of oversteer : the tendency of an automobile to steer into a sharper turn than the driver intends sometimes with a thrusting of the rear to the outside also : the action or an instance of oversteer.
How do you correct oversteering?
Luckily, lift off oversteer can usually be corrected by reapplying the throttle and accelerating. This should pull the front of the car forwards and straighten out the car, but continuing to reduce throttle application can cause the car to spin.
How do I fix oversteering?
Ways to Correct Oversteer
- Lower front tire pressure.
- Raise rear tire pressure.
- Stiffen front shocks.
- Soften rear shocks.
- Raise front end.
- Lower rear end.
- Install narrower front tires.
- Install wider rear tires.
How can I stop oversteering?
Simple modifications to make a car less prone to oversteer
- Reducing the rear tyre pressure.
- Softening rear springs or anti-roll bar.
- Use softer rear tyres.
- Increase rear down-force (if aerodynamics fitted)
How do you prevent oversteer?
How do you fix understeering?
How to correct understeer
- Reducing tyre pressure or using softer tyres at the front of the car.
- Softening the anti-roll bar or front springs.
- If aerodynamics are fitted, increasing the front downforce.

What is understeering and oversteering?
Understeering is the exact opposite of oversteering in the sense that you slide into the ditch face-first. Understeering occurs when the vehicle you are driving simply doesn’t respond to your steering commands and continues moving forward in a straight line, despite the wheels having been turned to one side or the other.
How do you measure over and understeer?
Understeer occurs when the front tyres lose lateral traction causing the front end to push towards the outside of the corner and for the steering to become useless. To measure over and understeer you will need to measure tyre slip angle at each tyre.
How does oversteer affect the slip angle?
During a turning manoevre with oversteer (diagram on the right), the slip angle measured at the rear of the car is now showing a larger slip angle. The slip angles measured at the middle and front of the car in this case are now reduced, but still affected by the angle of the steered wheels.
Which direction is the vehicle oversteering through the curve?
For example, in the picture on the left, we can see that the vehicle is oversteering through the curve and is travelling generally in the direction of the front wheels, but the body of the vehicle is pointing towards the inner radius of the curve. True Heading Course over Ground Slip Angle
