Understeer is when you turn the steering wheel and through lack of grip, (caused by road conditions or possibly excess speed) the car does not follow i.e it goes straight on.
It's when a car has a tendency to continue straight in a turn. Oversteer is the opposite, when the rear of the car wants to whip out.
front wheel drive
One can learn more about oversteer and understeer from a driver's training instructor. Experience is also a great teacher, but maybe a dangerous one.
You may go off the road.
To the front. So, what can you do if understeer occurs? Look ahead, anticipate, and don't panic! Your best chance of correcting an understeer is to release the accelerator and stay off the brake. As the vehicle's weight shifts forward, it will load the front tires, improving their grip while you carefully decrease the steering angle. This improved grip and the slower speed should allow you to steer smoothly back into the path of travel
Understeer is when attempting to corner, the front wheels are turned in the direction you want to go, but the car travels forwards. (front wheel drive cars suffer this) Oversteer is when cornering the back end steps out and unless corrected quickly will cause the car to spin. (a trait of rear wheel drive cars)
MGM's usually understeer, if thrown into a corner too fast. Is your question why yours oversteers instead of under ??? Are front tires the correct size ??
Oversteer is a driving term used to describe the effect of the rear tyres of the car losing traction while turning a corner. This results in the back of the car sliding towards the outside of the corner and can result in a spin if not corrected by 'counter steering'.
The Electronic Stability Program, or ESP, is a car safety device that uses high-tech sensors, the carâ??s central computer, and mechanical actions. The ESP detects a loss of steering control. It can help correct an understeer or oversteer of a car. An understeer can occur if the carâ??s front wheels donâ??t have enough traction. An oversteer can occur if the car turns too far causing the rear wheels to slip. Some ESP systems can reduce engine power until control is regained.
The "ESP" system helps correct oversteer and understeer by breaking the inner or outer wheel as needed to get the car back on a straight path. When the light flashes the "ESP" system has detected this condition and has momentarily engaged.
The noise/squeeling is due to understeer caused by the back wheels pushing too hard oer the front wheels, this can also be attributed to suspention set-up and wing set-up
There are several words for wheels losing traction; spinning, sliding, drifting, breaking free... If it happens to the front wheels while cornering it'll cause understeer = the car will continue straight forward despite the driver trying to turn.
AnswerThe dynamic stability control is the active safety system used in BMW to control your car traction control. It controls the understeer or the oversteer of your car. Understeer means the front wheels going straight although you steer to right or left whereelse the oversteer happens when your rear wheel sliding out during cornering. On understeer the brake force applied to the rear in order to stabilize the car where as on oversteer the brake force applied on the front left or right depends where you are turning. If you turn right then the force will be on front left and vice versa.The yellow brake warning lights stays on due to your brake pads being almost finished or your brake fluid level droped. Please check at the nearset workshop.Those 2 lights came on together in my 2001 BMW Z3 because the steering arm positioning sensor under the drivers seat needed to be replaced. This is not an inexpensive fix at the service center. Runs about $600.
