- Brake Pre-tensioning shortens stopping distances during an emergency stop by priming the brakes should the driver lift off the accelerator sharply in preparation.
- Brake Drying improves braking performance in the wet by periodically applying the brake pads to scrub away the film of water that can build up on the brake discs.
- Hill Start Assistant allows a manual transmission car to pull away smoothly on a gradient without rolling backwards, courtesy of the brakes being held for the short time it takes the driver to apply the accelerator after releasing the foot or handbrake.
- Brake Fade Compensation applies additional braking without any extra effort from the driver should sensors detect that the brake pads are starting to lose 'bite' due to heat build up.
In another first on an X model the driver will now be able to select the Dynamic Traction Control (DTC) function of DSC. DTC allows for a greater degree of wheel slip for more spirited driving without the main traction control system safety net intervening. This option can be selected via a button on the centre console.
Prices and full specification of the new X3 will be announced before its on sale date in the Autumn.
