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.
The driver can select between the D and S modes and can use the special RS shift paddles on the steering wheel for manual gear changes. All commands are transmitted to the transmission electrically - by wire. The dynamic starting function controls starts with optimum traction. Using it, the Audi RS5 Coupe can unfold its full acceleration potential. Prerequisite: the ESC sport mode must be active and the selector lever must be in the S position.
With the newly developed 2.9 TFSI, Audi has drawn upon the legendary 2.7 liter V6 from the first RS4 Avant. Produced between 1999 and 2001, it delivered 280 kW (380 hp). Just like the 2.7 liter engine, the new high-performance V6 is also designed as a bi-turbo engine. In comparison with its direct predecessor, a freely-aspirated, high-revving V8 unit, its pulling power and efficiency attain a whole other dimension.
