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.
In comparison with the A5 Coupe, the Singleframe radiator grille appears broader and flatter thanks to its new honeycomb structure. It bears both the quattro lettering and the RS5 emblem. Beneath it, a blade in contrasting color runs between the air inlets, connecting these with one another. These also adopt the three-dimensional honeycomb structure and underline the dynamism of the RS5 Coupe.
A further efficiency component of the 2.9 TFSI is the thermal management system. The crankcase and the cylinder head have separate coolant circuits. After a cold start, the switchable water pump controls the flow of coolant through the engine so that the oil is warmed up as quickly as possible. The exhaust manifolds are integrated in the cylinder head, and coolant circulates around them which helps ensure rapid warming up. When the engine is warm, this technology lowers the exhaust temperatures - consumption drops drastically, especially when driving in a sporty way. The great efficiency of the V6 bi-turbo is also partly to do with low friction. For example, the fully adjustable oil pump only builds up as much pressure as necessary.
