A handling characteristic in which additional steering lock is required as speed increases around a constant radius turn. An understeering car breaks away at the front end first because the front tires run at larger slip angles than the rear tires; also called "push". A characterization usually attributed to race drivers is that cars that understeer go through the fence nose first, and cars that oversteer go through tail first.
Where the slip angle of the front wheels are greater than that of the rear wheels. The front tires lose grip before rear tires do. The angle of the steering wheel is greater than normal -- requires more steering by driver. Happens more often in cars equipped with front wheel drive. Slight understeer is actually a desired condition.
results when the slip angle of the front tires is greater than the slip angle of the rear tires. A greater steering angle is then required in order to maintain the turn. When the steering angle reaches full lock and the turn cannot be maintained, the vehicle drifts to the outside. In an understeer condition, the driver is attempting to negotiate a turn, but the vehicle mushes ahead refusing to cooperate.
Understeer is a condition where the front wheels provide less steering than desired in a given direction.
A loss of traction in a vehicle's front tires, caused by excessive speed in relation to a cornering angle, causing the vehicle to slide outwards during a turn. (taking a turn too fast and not being able to hang it, your car starts to slide outward; not good and not fun)
The tendency of a car to go straight instead of turning when the tires are pushed to their grip limit. Also known as pushing. (See overdriving/overcooking). This is one of the most annoying handling characteristics of stock vehicles, especially front wheel drives. Cars are set up from the factory to understeer, because it is safer for the average person to deal with understeer than oversteer in an emergency braking situation on the street. The inherent characteristics of an FWD (front wheel drive) car; front engine, front drive, front wheels doing all the turning and most of the braking, make the front wheels do all the work. This causes them to run out of traction if they are trying to do too many things at once. This is best demonstrated if you try to brake hard and turn at the same time. The car goes straight ahead since it is too busy trying to stop to bother with your annoying pleas to "TURN TURN TURN!". Much of this can be addressed by training the driver. The rest can be handled with stiffer springs, larger stabilizer bars, and tire size/pressure adjustment, in respective order from drastic to subtle.
A lack of grip at the front wheels, which makes the car feel to slip away at the front, when cornering.
The tendency of a vehicle to turn less than the driver intends; the sideways slip of the front wheels more than that of the rear wheels; the front of the vehicle tends to drift or plow to the outside of the turn
Tendency of a car to turn less sharply than the driver intended, especially a front wheel drive vehicle under hard acceleration.
When the front tires lose traction while cornering, causing the front of the car to slide. Also referred to as "push" or "plow".
Also known as pushing, understeer is prevalent on front-drive cars when driven hard. The front of the car resists turning and wants to go straight. Some cars are designed to understeer because it is thought to be safer and easier to manage for average drivers than oversteer.
A handling condition in which the front tires' change of slip angle is greater than that of the rear tires. In accelerating an understeering car on a constant radius (a skidpad, for example), a driver would have to increase the steering angle. In particular, it need not imply sliding. Yet also be aware of understeer's technically extreme — but commonly accepted — usage for describing a car whose front end breaks away before the rear. In NASCAR parlance, "tight" or "push."
Occurs when the wheels are turned, and the car does not turn at the same rate. Causes the front of the car to take a wider apex than the driver's steering lock requires. Also called push, or tight in the US. Can be corrected by adding more front downforce, sofening springs and rollbar, or reducing front tyre pressure. Extreme conditions cause a car to go straight on instead of turning for a corner.
Cornering characteristic in which the tyres at the front develop more slip angle than those at the rear, causing the car's front to run wide on a corner.
Understeer is characterised by the front end of the car losing grip. This gives the rear of the car a tendency to carry straight on, through a corner.
Where the front end of the car doesn't want to turn into a corner and slides wide as the driver tries to turn in towards the apex.
A condition in which the rear tires have more traction than the front tires. The front tires will slide across the track toward the outside wall rather than turning into the corner. Also called push.
Not surprisingly, this is the opposite of oversteer and means a car turns into a corner to a lesser degree than the driver intended. In other words, you turn the steering wheel and the car keeps going straight ahead as the front wheels slide across the road surface. It's usually exhibited by front-wheel-drive cars with an unhealthy forward weight bias but is far from unknown in rear-drive cars. Manufacturers often tune a car's handling to exhibit understeer, believing it to be safer because a driver will naturally back off the throttle, which usually helps bring the car back into line.
Same as Push or Tight. Typically describes a cornering condition where the front t ires lose adhesion before the rear tires, resulting in a car that feels like it wants to go straight. Solutions include more front wing to press the tires harder to the ground, softening the front anti-roll bar setting or spring rates in order to provide more grip, or by making changes to reduce grip at the rear such as reducing the rear wing angle or stiffening the rear anti-roll bar setting or spring rates. Here is an easy way to remember whether a car is loose (oversteer) or tight (understeer), as originally described by Bobby Unser. "If the front end hits the wall, it's understeer. If the rear end hits the wall, it's oversteer."
Understeer occurs when the front wheels provide less steering than desired in a given direction. Usually the front wheels have lost adhesion and cannot steer effectively. This results in the vehicle "pushing" ahead and responding sluggishly to the steering wheel. Reducing speed can allow the front wheels to regain traction. Most vehicles are designed to exhibit understeer in normal conditions, because it is easier to control than oversteer.
The tendency of a car to continue straight ahead while negotiating a turn.
A condition in which a vehicle turns at a smaller angle than that of the steering wheel input because of rear tire slippage. When this occurs, the steering wheel must be turned at a greater angle to achieve the desired turn. Understeer will be affected by the amount of wheel turn lock-to-lock, as well as the vehicle's weight and the speed of the vehicle when encountering turns Oversteer, which means the vehicle turns more than steering wheel input and indicated by front tire slippage, can make the vehicle hard to control. Because of this, engineers often design suspensions that tend toward understeer as a safety measure

A handling condition in which the slip angle of the front tires is greater than the slip angle of the rears. An understeering car is sometimes said to push, because it resists turning and tends to go straight.
This is when the front wheels ‘push’ wide during cornering, from the outside it looks like the car is traveling straight on and will not turn for the corner.
The condition that exists during cornering when the front of a vehicle tends to skid before the rear.
The opposite of oversteer, this is when a vehicle turns much less than the driver desired it to. This is a state of affairs that is more commonly encountered when cornering aggressively in FWD than RWD vehicles because sudden power to the front wheels can cause them to lose traction and push onwards without turning well. (See also Electronic Stability System, FWD, Oversteer, and RWD).
The cornering condition where the front tires are cornering harder than the rear tires.
Understeer is a term for a car handling condition during cornering in which the circular path of the vehicle's motion is of a markedly greater diameter than the circle indicated by the direction its wheels are pointed. The effect is opposite to that of the oversteer and in simpler words understeer is the condition in which the front tires don't follow the trajectory the driver is trying to impose while taking the corner, instead following a more straight line trajectory.
