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.

They reinforce the transition from the front body to the interior, the front zone of the roof frame, the B-pillars, side sills and parts of the floor. The proportion of these parts in the body structure is 17 percent. A carbon roof with visible fiber structure is also available as an option, delivering a further weight saving of 3 kilograms (6.6 lb).

RS sport seats - optionally available in fine Nappa leather with honeycomb pattern - and the flat-bottomed RS multifunction sport leather steering wheel underscore the character of the high-performance Coupe in the interior as well. The steering wheel rim bears the RS badge, as do the front seat backrests and the shift gate. Special RS displays in the Audi virtual cockpit provide information on tire pressure, torque and g-forces. A shift light prompts the driver to upshift upon reaching the rev limit. The RS design package brings the sporty contrast color red into play on the center console as well as on the armrests, the seat belts and the floor mats with RS logo. The steering wheel, selector lever and knee pads are all covered with Alcantara. The Sonoma green design package from Audi exclusive enriches the interior with appropriately colored contrasting stitching - perfect for the new, exclusive exterior color.
Libby Wade Audi, 2017-10-13 19:50:59. The axle concept of the new RS5 Coupe enables optimal absorption of longitudinal and transverse forces. A revised five-link construction is used on the front axle. At the rear, a five-link suspension replaces the trapezoidal-link suspension used on the previous model. This benefits the sporty driving characteristics and agility. It also improves comfort significantly. With the standard RS sport suspension, the new RS5 Coupe sits 7 millimeters (0.3 in) lower than the base model. Audi Sport offers the RS sport suspension plus with Dynamic Ride Control (DRC) as an alternative. It uses steel springs and three-stage adjustable dampers that are connected to one another via diagonal oil lines and a central valve. When cornering at speed, the valves regulate the oil flow in the shock absorber of the spring-deflected front wheel at the outside of the curve. They increase the support provided and reduce pitch and roll movements. They thus connect the vehicle more closely to the road and improve handling. A new damper generation with integrated control valve ensures much more noticeable spread between the individual modes of the Audi drive select system.

This uses a superposition gear to vary its ratio by up to 100 percent, depending on the car‘s speed and the mode selected in the Audi drive select dynamic handling system. At the cornering limits, the system countersteers with tiny impulses, thus further boosting the dynamism and driving safety. In the dynamic setting within Audi drive select, the superposition of the dynamic steering is stiff in order to support a more sporty driving style.

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.
Caitlin Duncan Audi, 2017-10-13 19:47:21. The chain drive uses a new concept to reduce the drive power required: the crankshaft drives the balancer shaft via gears, with the shaft lying far down in the V of the cylinder banks. From here chains run to the four camshaft sprockets. These are trioval in shape, i.e. they have a slightly triangular shape, in order to compensate for peak forces. The balancer shaft rotates on roller bearings with particularly low levels of friction.

Alongside them are additional lateral air inlets, which make this top-performing athlete appear even wider and more aggressive.
Paige Dodd Audi, 2017-10-13 19:47:59. 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.
Shannon Griffin Audi, 2017-10-13 19:40:54. From 1,900 to 5,000 rpm, the 2.9 TFSI supplies the crankshaft with an impressive 600 Nm (442.5 lb-ft) of torque, which is 170 Nm (125.4 lb-ft) more than on the previous model. With its 331 kW (450 hp) - which equates to a power ratio of 155.5 hp per liter displacement - the unit accelerates the new RS5 Coupe from zero to 100 km/h (62.1 mph) in 3.9 seconds and thus six tenths of a second faster than before. If the customer orders the RS dynamic package, Audi increases the electronically restricted top speed from 250 km/h (155.3 mph) to 280 km/h (174.0 mph).
