116. Esp
ESP (Electronic Stability Program), also known as Electronic Stability Control (ESC), is an active safety system designed to help prevent a vehicle from skidding or losing directional control. It compares the driver's intended direction with the vehicle's actual movement and can intervene when instability is detected.
ESP can automatically brake individual wheels and, depending on the vehicle, reduce engine power to help bring the vehicle back towards the intended path. The system operates within the limits of tyre grip and cannot overcome excessive speed or very slippery conditions.

What does ESP do?
ESP helps maintain vehicle stability when it detects that the vehicle is beginning to deviate from the driver's intended direction. It can selectively brake individual wheels and may reduce engine power to help restore control.
What is the difference between ESP and ESC?
ESP and ESC refer to the same general type of electronic stability-control system. ESP means Electronic Stability Program, while ESC means Electronic Stability Control. Vehicle manufacturers may also use other names for similar systems.
Can ESP prevent every skid?
No. ESP can assist in maintaining stability, but it cannot overcome the physical limits of tyre grip. Excessive speed, worn tyres, ice or other very slippery conditions can still cause a vehicle to lose control.
