Introduction

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, multi-

cylinder 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.
