The New Leon's Traction Control System (TCS) and latest generation Electronic Stability Programme (ESP) work together to manage and monitor contact with the road delivering increased performance and safety. TCS stops the wheels simply spinning and wasting power when you put your foot down while also providing that extra bit of control that makes the difference in performance. The latest generation ESP kicks in to provide a safer, smoother and more controlled drive, even when conditions are less than ideal. It monitors information from the steering wheel, tyres, brakes and accelerator and makes any adjustments necessary to make sure you always hug a perfect line.
