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 RS5 Coupe to be a step ahead of its competitors. Switchable engine bearings ensure comfort at idle. The new RS5 Coupe 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.
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.
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.
