whats esp on car

ESP in a car is the Electronic Stability Program, the electronic nanny that stops you pirouetting into a ditch when enthusiasm exceeds grip.

It watches steering angle, yaw and wheel speeds, then pinches individual brakes and trims engine torque to keep the car heading where you actually pointed it.

In Australia it’s commonly called ESC, and it’s been mandatory on new passenger cars for over a decade.

You can usually switch it off for sand or sloppy tracks, but it’ll often jump back in if things get too lively.

If the ESP light stays on, get it scanned—often a crook wheel-speed sensor or steering-angle calibration—don’t ignore your safety net.
