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.
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.
Sporty interior in black and red: the flat-bottomed RS sport leather steering wheel is standard, as are the stainless steel pedals and RS sport seats. As an option, they can be covered in fine Nappa leather with honeycomb pattern. Red contrasting stitching adds emphasis to the steering wheel, center console, armrests, seats and floor mats. Carbon decorative trim underlines the dynamic appearance. The horizontal architecture of the instrument panel creates a vast sense of spaciousness in the high-quality, sportily appointed interior of the new RS5 Coupe. As standard, it welcomes the driver and passengers with illuminated door sills bearing the RS5 logo. LED light guides trace the contours of the doors and the center console - doing so in 30 different colors in combination with the optional ambient lighting. The interior is black. RS sport seats with rhombus pattern and embossed RS emblem underline the character of the high-performance Coupe. They are available in a combination of leather and Alcantara, and feature seat heating and a lumbar support. The RS sport seats are optionally available in fine Nappa leather with honeycomb pattern and contrasting stitching. They are also available in perforated Milano leather.
