what does understeer mean?

hehehe. for a good description, i would hit the search button, or google 'understeer'. this would help you more htan i can but....

understeer is where, while cornering, the car tends to push out of the corner, running off the road. it is a trait exhibited by front wheel drive cars in particular, as the front wheels lose traction while trying to push the car forward and turn. understeer is seen as being safer for novice drivers in comparison with oversteer, which is where the rear of the car will push out on a corner, and if miscontrolled will lead into a spin = hard for novices.

does this help you?

yea so if u turn like slowly it wouldnt do dat yea

[saxman]

basically

understeer = front wheels lose traction first
oversteer = rear wheels lose traction first

You don't have to "run off the road" to understeer around a corner; It is simply the car not turning in the complete direction of the wheels, only part of it.

The answer; just turn the wheel more :D

or just let go of the accelerator.

thats true. but the feeling is that the car is moving to the edge of the road. it doesnt have to fall off to understeer. and yeah to counter it, back off the throttle = oversteer as the front wheels gain traction

Oversteer and Understeer

Fortunately, a well designed car does not suddenly break into a skid. As the tyre approach their traction limits, they tend to slip sideways across the road. The angle between the tyres actual path and its natural path is called its slip angle. This gives the driver advance warning that the front/rear of the car is in danger of breaking loose and starting a skid.

If the rear tyres approach their traction limit more rapidly than the front, then the effect is for the rear of the car to steer a wider path than the front wheels. This rotates the car more than the driver intended and, if nothing is done, leads to the car turning a smaller radius corner. When this occurs the car is said to oversteer.

If the front tyre approach the traction limit more rapidly, the effect is that the front of the car takes a wider radius curve than the driver intended. The car is said to understeer.

Understeer is safer than oversteer. If the car understeers, and no correction is made the result is a wider corner than intended, but the car remains stable. If the car oversteers, the turn made has smaller radius than intended. The smaller radius produces higher cornering forces bring the required traction even closer to the limit of the rear wheels, and thus causing even more oversteer. The situation becomes worse until the rear wheels lose grip completely; the car spins and all directional control is lost.


There you go. I googled that and in .001 seconds the answer was there :)
