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.
Thus in 2012,
for instance, both the Audi R18 e-tron
quattro and the Audi R18 ultra drove to podium
finishes at LeMans with a V6 engine, whereas their
victorious predecessor in 2010, the R15 TDI, had
featured a V10 engine.
