Merc Sprinter gets ESP upgrade for 2012
Mercedes-Benz will be fitting the latest generation Bosch Adaptive 9i ESP system to all Sprinters as standard from January 2012. Like the current Adaptive ESP 8.1 system, fitted since the current generation Sprinter was introduced, the new ESP 9i takes the vehicle load into account. Depending on the weight and position of the vehicle's centre of gravity, the ESP sensors enable the load to be calculated at any given time, ensuring that it can stabilise the vehicle when necessary.Adaptive ESP 9i brings with it two additional features — Brake Disc Wipe and Electronic Brake Prefill. In wet weather, the former applies light braking pressure to the brakes at regular intervals to clear water from the discs. If emergency braking becomes necessary, full braking power is available immediately, reducing the stopping distance compared with wet discs.
If the accelerator pedal is released suddenly, Electronic Brake Prefill automatically and gently applies brake pressure to eliminate in advance the air gap between brake pad and disc. If emergency braking then occurs, milliseconds will have been saved as the friction surfaces will already be in contact, resulting in a shorter stopping distance.
