Just like the entire A5 model family, the new Audi RS5 Coupe also benefits from a drastic reduction in weight. It weighs in at 1,655 kilograms (3,648.7 lb) - 60 kilograms (132.3 lb) less than previously. The body of the new RS5 Coupe is among the lightest in the segment. Thanks to geometrical lightweight construction and an intelligent mix of materials, it weighs 15 kilograms (33.1 lb) less than the body of the previous model. The module cross member under the instrument panel, for instance, consists of extruded aluminum profiles and sheets, and the front cross member is an extruded profile.
The luggage compartment offers ten liters (0.4 cu ft) more volume than before. It now holds a best-in-segment value of 465 liters (16.4 cu ft). The tailgate opens automatically and the two-door Coupe can be ordered from Audi with optional sensor control. With this, a proximity sensor in the rear bumper reacts to a kicking motion. The tailgate unlocks and opens automatically if the optionally available advanced key is detected.
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.
