About weight reduction

The demands placed on modern vehicles are

contradictory. On the one hand, they must

offer enhanced performance and comfort, on

the other they need to be more economical

and efficient. Audi ultra resolves this conflict

by examining each and every component. We

demand the highest functionality combined

with the lowest possible weight. The result is

an intelligent mix of materials that even

allows a reduction in engine size: lighter

vehicles no longer need a large engine to

be agile. In 2012, for instance, both the Audi

R18 e-tron quattro and the Audi R18 ultra

drove to podium finishes at Le Mans with a

V6 engine, whereas their victorious

predecessor in 2010, the R15 TDI, had

featured a V10 engine.
