The styling packages - gloss black, carbon and matt aluminum - provide even more customization options. Overall, the Audi RS5 Coupe is available in seven colors, with Audi Sport also offering the exclusive paint color Sonoma green metallic. In the Audi exclusive range, there are also numerous freely selectable exterior paint finishes available.
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.
An important component of the B-cycle combustion process is the central position of the injectors in the combustion chamber. In the area around the inlet valve, this makes possible a geometry which, in interaction with the inlet ports, allows for targeted mixing up of the gas charge. The common-rail system injects the fuel into the combustion chamber with 250 bar of pressure - the high injection pressure ensures a homogeneous spray pattern and consequently a uniform propagation of the flame front.
