The front of the Audi RS5 Coupe looks sportily aggressive thanks to massive air inlets and RS bumpers with a blade in contrasting color. The broad Singleframe with high-sheen black honeycomb grille and quattro lettering highlights an aluminum-look frame. A sharply drawn shoulder line in the form of the characteristic wave lends the new.
The fast, spontaneously and sportily shifting eight-speed tiptronic with optimized shift times is standard on the new Audi RS5 Coupe. The layout of its gear sets and shifting elements results in low drag torques and thereby to a high efficiency level. Its large number of gears very frequently makes it possible to operate the engine close to its ideal load point. The lower gears have short, sporty ratios, while the upper gears are long in order to reduce revs and fuel consumption.
In the induction tract, the intake valves close well before the piston reaches bottom dead center. This very short opening time keeps the fresh gas flow comparatively small. When the piston moves back up again after reaching bottom dead center, the compression phase starts later than usual. This allows a high geometric compression ratio of 10.0:1 - the combustion then takes place in a relatively small volume. In comparison to the short compression phase, the expansion phase is extended, which results in a high level of efficiency.
