The 2.9 TFSI V6 biturbo engine, which Audi developed from the ground up, offers sharp increases in power and efficiency as well as an incomparably full-bodied RS sound. It produces 331 kW (450 hp). Its peak torque of 600 Nm (442.5 lb-ft) – up 170 Nm (125.4 lb-ft) from the previous model – is available across a wide band from 1,900 to 5,000 rpm. The top model in the A5 family sprints from 0 to 100 km/h (62.1 mph) in 3.9 seconds and with the optional dynamic package reaches a top speed of 280 km/h (174.0 mph).

The 2.9 TFSI unit’s two turbochargers are positioned centrally between the cylinder banks. The ingested air flows to the respective turbocharger and into the combustion chambers through a dual-branch system for spontaneous response.
The B-cycle combustion process with central direct injection represents a new level of efficiency among the RS models. The shortened compression stroke used here enables an engine process with a significantly higher geometric compression ratio. Combined with a power stroke that, while normal, is longer relative to the compression stroke, this allows for more efficient combustion and increased engine efficiency. In the NEDC, the V6 biturbo consumes just 8.7 liters of fuel per 100 kilometers (27.0 US mpg), corresponding to 197 grams CO2 per kilometer (317.0 g/mi).

This is an efficiency gain of 17 percent over the previous model. Another factor in the greater efficiency of the newRS 5 Coupé is its significantly lower weight. It tips the scales at 1,655 kilograms (3,648.7 lb), 60 kilograms (132.3 lb) less than before. A roof of carbon with a visible fiber structure is available as an option.
The biturbo’s power flows through a sportily-tuned, eight-speed tiptronic with optimized shift times to the quattro permanent all-wheel drive. The drive forces are distributed asymmetrically to the axles (40:60) to guarantee dynamic handling with optimal traction and the greatest possible safety. Audi Sport also offers an optional rear sport differential.
An updated 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 Audi RS 5 Coupé sits much lower than the production model.
Audi Sport also offers the RS sport suspension with Dynamic Ride Control (DRC), ceramic brakes and dynamic steering with RS-specific tuning. Drivers can make their personal driving experience more individual, dynamic or comfortable using the standard Audi drive select system.
