Ojito al trabajo de pesos, casi han conseguido el mismo ratio peso/potencia que el CSL sin renunciar a las comodidades de una berlina
Audi’s FSI technology has already proven its qualities impressively in Audi’s four-time Le Mans winner, the Audi R8.
A further essential point in the brief given to Audi’s development engineers was to optimise the car’s power-to-weight ratio, avoiding every superfluous gram on the Audi RS 4. Accordingly, virtually every component was checked and cross-checked for minimum weight. The front wheel arches and the engine compartment lid are therefore made of aluminium, just like most components on the chassis and suspension. The specially designed RS bucket seats, in turn, are not only very light, but also offer extremely good body support in every situation.
The result is a power-to-weight ratio of just 3.93 kilos per bhp – a figure truly reminiscent of a thoroughbred sports car, which would not even have been conceivable just a few years ago in a midrange saloon.
(NOTE. The BMW M3 CSL has 3,9 Kg / hp, and the M3 4,6 Kg / hp)
