Self Study Program 921403 – 6.0L W12 Engine in the Audi A8L

VAG SSP 921403. The new top of the line models from the Volkswagen Group feature an innovative generation of W engines developed from the model used for the VR engine family. To achieve this, mass produced components have been integrated into a completely new engine concept.

This process has yielded compact, multicylinder gasoline engines of a consistently high standard not previously achieved in passenger car series production.

For example, the W12 6.0 L engine, featured for the first time in the Audi A8L, is currently the most powerful 12-cylinder engine available in this vehicle class, providing a combination of quality and optimum performance.
