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.
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.
A further efficiency component of the 2.9 TFSI is the thermal management system. The crankcase and the cylinder head have separate coolant circuits. After a cold start, the switchable water pump controls the flow of coolant through the engine so that the oil is warmed up as quickly as possible. The exhaust manifolds are integrated in the cylinder head, and coolant circulates around them which helps ensure rapid warming up. When the engine is warm, this technology lowers the exhaust temperatures - consumption drops drastically, especially when driving in a sporty way. The great efficiency of the V6 bi-turbo is also partly to do with low friction. For example, the fully adjustable oil pump only builds up as much pressure as necessary.
