Each of the two turbochargers on the 2.9 TFSI is assigned to a single cylinder bank and can build up a maximum of 0.95 bar charge pressure. Like with all new V6 and V8 engines from Audi, the turbochargers are installed within the 90-degree angle of the cylinder banks, and thus the exhaust side of the cylinder heads is on the inside, while the intake side is on the outside of the engine. This layout enables compact construction and short gas flow paths with minimal flow losses - the 2.9 TFSI responds extremely spontaneously to movement of the accelerator pedal.
Audi RS5 Coupe an emotively elegant expression. For the first time, it now has a three-dimensional form and thus creates interplay between light and shadow. quattro blisters on the flanks emphasize the pronounced bulges over the wheel arches, which have been widened by 15 millimeters (0.6 in). The widened door sills are painted in the vehicle color and also feature inserts in black or optionally carbon. The exterior mirror housings are in matt aluminum look and optionally also in carbon, in the vehicle color or in black.
The chain drive uses a new concept to reduce the drive power required: the crankshaft drives the balancer shaft via gears, with the shaft lying far down in the V of the cylinder banks. From here chains run to the four camshaft sprockets. These are trioval in shape, i.e. they have a slightly triangular shape, in order to compensate for peak forces. The balancer shaft rotates on roller bearings with particularly low levels of friction.
