The RS 5 Coupé is the star athlete of the A5 family. It offers the power and handling of a powerful sports car packaged in the body of an alluringly elegant coupe. The design has now gained several new, sharp accents, with numerous features that characterize the other A5 models also making their way to the RS 5.
The Audi RS 5 Coupé uses a high-revving, normally aspirated V8 displacing 4,163 cc. This engine is closely related to the V10 that powers the R8 high-performance sports car. The 4.2 FSI delivers 331 kW (450 hp) at 8,250 rpm, with the peak torque of 430 Nm (317.15 lb-ft) available between 4,000 and 6,000 rpm. The engine has a specific output of 108.1 hp per liter of displacement. The potent response, the eager revving and the rich, melodious sound mark the V8 as a thoroughbred racing engine.
Hand-built at the plant in Györ, Hungary, the 4.2 FSI launches the Coupé from zero to 100 km/h (62.14 mph) in 4.6 seconds. Audi will increase the electronically governed top speed from 250 to 280 km/h (155.34 to 173.98 mph) upon request. Thanks to the combination of technologies from the Audi modular efficiency platform, which also includes a recuperation system, the high-tech V8 consumes significantly less fuel on average than its direct competitors.
With its high efficiency and its long top gear, the standard seven-speed S tronic also contributes to the good fuel economy. Drivers can let the lightning-fast dual-clutch transmission shift automatically or change gears themselves using the selector lever or with paddles on the steering wheel. The integrated launch control program provides for rocket-like starts by managing the engagement of the clutch at mid-level revs.
High end: quattro with crown-gear differential
Like all RS models, the RS 5 Coupé also applies its power to the road with quattro permanent all-wheel drive. The crown-gear center differential at its heart is compact and lightweight. It can vary the distribution of torque between the front and rear axles lightning-fast and over a wide range, with up to 70 percent flowing to the front or as much as 85 percent to the rear, as necessary. The default 40:60 ratio of the rear-biased configuration ensures sporty handling.
The crown-gear center differential works together with the torque vectoring system, which acts on all four wheels. If the load on the inside wheel is reduced too much while the car is being driven dynamically, that wheel is braked slightly before it can begin to slip. Audi offers the sport differential as a complementary option that actively distributes the power between the rear wheels via two superposition stages.
