Details & Technology
The adaptive Electronic Stability Program ESP
®
Version 9i has a better braking performance in the
wet (Brake Disc Wipe) and a faster braking response (Electronic Brake Prefill) in an emergency than
the preceding version. Pedal feedback and noise characteristics have also improved:
Brake Disc Wipe:
In rainy conditions the brakes are slightly engaged to wipe water of the brake discs, so that full braking
performance is assured in the event of hard braking.
Electronic Brake Prefill:
If the driver's foot is suddenly and rapidly removed from the accelerator, the brakes are lightly
engaged to eliminate the air gap between the brake pad and disc. This ensures that full brake
performance is available in the event of hard braking.
