How It Works

How It Works - The system works by monitoring the speed of all four wheels using the ABS system or specially fitted sensors.

The system works by monitoring the speed of all four wheels using the ABS system or specially fitted sensors.


 When wheel spin is detected the engine power is reduced, by cutting a single injector pulse, until grip is resumed. This occurs in a thousandth of a second, and appears to the driver as a slight misfire with no loss in acceleration.

Maximum acceleration is achieved by limiting the slip between the tyre and the road. The point at which a tyre is just beginning to slip against the road gives the maximum coefficient of friction value.

From the graph above it can be seen that the maximum coefficient of friction (
