Just like the entire A5 model family, the new RS 5 Coupé (combined fuel consumption in l/100 km: 8.7; combined CO2 emissions in g/km: 197) 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 RS 5 Coupé 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 front strut domes are made of highly integrated cast aluminum parts. Compared to sheet steel components made of many individual parts that are welded together, they are eight kilograms (17.6 lb) lighter. This construction allows a very stiff connection between the upper links and the body for the best-possible steering response – optimal conditions for dynamic handling.
Hot-formed parts form the high-strength, crash-safe backbone of the occupant cell. They reinforce the transition from the front body to the interior, the front zone of the roof frame, the B-pillars, side sills and parts of the floor. The proportion of these parts in the body structure is 17 percent. A carbon roof with visible fiber structure is also available as an option, delivering a further weight saving of 3 kilograms (6.6 lb).
The excellent torsional rigidity of the body is the foundation for a highly precise driving response as well as for peace and quiet on board. This allows the new RS 5 Coupé to be a step ahead of its competitors. Switchable engine bearings ensure comfort at idle. The new RS 5 Coupé also scores top marks for passive safety. In the interior, the adaptive occupant restraint system for the front seats offers outstanding protection. It adjusts the effect of the front airbags and the seat-belt force limiters to the seating position of the driver and front passenger as well as to the type of frontal collision.
