What is ESC (electronic stability control)?

ESC or electronic stability control is a system that helps reduce the chances of skidding out while cornering. Some brands have specific names for this system, such as BMW, which calls it Dynamic Stability Control. ESC uses sensors to measure the speed of your car's wheels, along with the direction it's headed and how you're turning the steering wheel to determine the direction you're trying to go. If it detects any understeer or oversteer, which will cause the car to stray from your intended line, it will rapidly brake individual wheels to bring the car back under control. We'd recommend leaving ESC on at all times while driving as it'll help protect you if you hit a slippery patch on the road, or if you misjudge your speed through a corner.
