About weight reduction<br />

The demands placed on modern vehicles are<br />

contradictory. On the one hand, they must<br />

offer enhanced performance and comfort, on<br />

the other they need to be more economical<br />

and efficient. <strong>Audi</strong> ultra resolves this conflict<br />

by examining each and every component. We<br />

demand the highest functionality combined<br />

with the lowest possible weight. The result is<br />

an intelligent mix of materials that even allows<br />

a reduction in engine size: lighter vehicles<br />

no longer need a large engine to be agile.<br />

Thus in 2011, for instance, the <strong>Audi</strong> R18 TDI<br />

drove to podium finishes at Le Mans with a V6<br />

engine, whereas their victorious predecessor<br />

in 2010, the R15 TDI, had featured a V10<br />

engine.<br />
