Self Study Program 326 – Audi A6 2005 – Electrics

VAG SSP 326. The Audi A6 – the most progressive vehicle takes the lead. The new Audi A6 consistently adopts the highly networked electronic architecture, which is already used in the Audi A8. Overall, new technologies allow the A6 to match up with its “model” vehicle, the Audi A8. Features, which were previously reserved for luxury vehicles, are now also available in the topclass segment.

In combination with these diverse capabilities, the underlying technology has, of course, been enhanced considerably.

The use of the most modern network technologies, such as CAN, LIN, MOST and Bluetooth, and the related distributed vehicle functions signals the arrival of a new generation of vehicle electrics in this class.

Some of these are safety-related features, such as the combined rain/light sensor or the pivoting cornering headlight. Comfort features of the top class, such as the MMI operating system or sophisticated functionalities for the mobile baseplate, which is available ex-works, are part and parcel of these new saloons.

The new Audi A6 has everything that is needed to become the Number One model in the top-class range.

It combines many different, attractive components to form one unit. Design and performance go hand-in-hand. The new Audi A6 will take over as the most progressive vehicle.
