Robert Bosch has improved the face-lifted Audi A4s standard electronic stability control system. The German supplier has added a brake wipe function that automatically applies light pressure to the brake discs when the car is traveling on wet roads. Keeping the discs dry means that stopping distances are shortened.
Suppliers of stability control technology such as Bosch, Continental Teves, Denso, Delphi and TRW Automotive are working hard to incorporate extra functionality into their systems because growing penetration rates is putting pressure on margins.
Also new for the A4s mid-life upgrade: optional xenon plus front lights from Valeo that incorporate a dynamic adaptive light system.
The A4 is assembled at Audis plant in Ingolstadt, Germany. The Volkswagen subsidiary sold a little more than 310,000 units of the A4 in 2004. That included about 60,000 sales of the face-lifted A4, which went on sale in November 2004
