Traction control vs. Stability control

Can anyone explain the difference? TIA.

Traction control is a system that allows a vehicle to send power away from wheels that are slipping. It is useful to get a little more grip in slippery conditions, but most systems are limited to lower speeds.

Stability control is a system that detects the movement and speed of the vehicle. If it senses the car begin to swerve or spin, it helps to compensate to allow the driver to keep control of the vehicle.

Most stability control systems will include traction control, since the hardware is essentially the same. On the other hand, many vehicles have traction control but not stability control, which is more expensive to add.

Some AWD vehicles do not need traction control since they use a more robust system to accomplish the same effect. An AWD vehicle can still benefit from stability control, however.

Stability control is proving to be a very important safety feature, especially for top heavy trucks and SUVs that would otherwise have a higher rollover risk and poor emergency handling.

To add to the above:

You want traction control so you don't get stuck in snow, mud, wet, as easily.

You want Stability control so your car will help keep under control in emergency handling situations.
