Both turbochargers of the 2.9 TFSI unit are centrally positioned inside the V of the engine and each of them supplies a single cylinder bank. The B-cycle combustion process with central direct injection represents a new level of efficiency within the RS family. In the NEDC, the V6 bi-turbo consumes just 8.7 liters of fuel per 100 kilometers (27.0 US mpg), which corresponds to 197 grams of CO2 per kilometer (317.0 g/mi). This is an efficiency gain of 17 percent over the previous model. Also beneficial for the new Audi RS5 Coupe is a drastic reduction in weight. The vehicle weighs in at 1,655 kilograms (3,648.7 lb) - 60 kilograms (132.3 lb) less than previously. A carbon roof with visible fiber structure is also available as an option.
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.
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.
In the induction tract, the intake valves close well before the piston reaches bottom dead center. This very short opening time keeps the fresh gas flow comparatively small. When the piston moves back up again after reaching bottom dead center, the compression phase starts later than usual. This allows a high geometric compression ratio of 10.0:1 - the combustion then takes place in a relatively small volume. In comparison to the short compression phase, the expansion phase is extended, which results in a high level of efficiency.
