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.
A comprehensive range of infotainment choices is sure to keep everyone on board entertained. Optionally available, the MMI navigation plus with MMI touch includes the Audi connect hardware module. This connects the new RS5 Coupe to the internet using LTE technology. Thanks to the Audi connect SIM, which is permanently installed in the car, the flat-rate data package for the connect services including Europe-wide roaming is free of charge for three years. Passengers can browse the internet with their mobile devices via the Wi-Fi hotspot option. The Audi smartphone interface uses Apple Car Play and Android Auto to make selected apps available in a separate MMI menu. Operation is easy and intuitive, thanks to natural language voice control, free text search function and the multifunction steering wheel. The touchpad in the center console can be used to zoom, scroll and enter characters. Further high-end technologies, such as the head-up display and as many as 30 driver assistance systems enhance safety, comfort and efficiency. The intelligent interplay between these systems represents another step towards piloted driving.
In the classic Miller cycle, the reduced cylinder charge is detrimental to torque and power output. These aspects have been neutralized by Audi thanks to the implementation of turbocharging and the two-stage Audi valvelift system (AVS). The four camshafts of the 2.9 TFSI can each be adjusted by 50 degrees crank angle. At higher load and engine speed ranges, AVS closes the inlet valve later. The opening time increases from 130 to 200 degrees crankshaft angle, while at the same time the valve lift increases from 6.0 to 10.0 millimeters (0.2 to 0.4 in). Cylinder charging also increases considerably - the 2.9 TFSI revs up powerfully and delivers an impressive output.
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.
