Audi RS 5
Unbridled power lurking in a classically elegant coupé: the Audi RS 5 will debut at the Geneva Auto Show. The high-revving 4.2-liter V8 with its 331 kW (450 hp) unleashes powerful performance while achieving remarkable fuel economy. The seven-speed S tronic and an innovative center differential in the quattro drivetrain transmit power to all four wheels.
Developed by quattro GmbH, the RS models comprise the dynamic spearhead of Audi‘s model range. The RS 5 is the latest torchbearer in a tradition dating back over 15 years to the RS 2 Avant: superior handling in the mid-size class.
A close relative of the V10 which powers the high-performance R8 sports car, the high-revving V8 engine delivers its output from a displacement of 4,163 cm3. Like nearly every Audi gasoline engine, this one also operates via direct fuel injection known by the abbreviation FSI. This same technology has propelled the Audi R8 racing car to four triumphs at the classic endurance race in Le Mans. The common-rail system generates up to 120 bars of pressure.
Intensive fine-tuning of the dual-branch intake and exhaust system allows the undersquare engine to breathe freely; four adjustable camshafts and tumble flaps in the intake manifold facilitate mixture formation. The 4.2 FSI provides imposing torque and is right at home even at high revs – almost like a race engine. The engine delivers 331 kW (450 hp) at 8,250 rpm and – between 4,000 and 6,000 rpm - transmits a maximum of 430 Nm (317.15 lb-ft) of torque.
The vigorous strength, the spontaneous responsiveness, the joyful high-revving, and the throaty, sonorous music: this V8 produced by hand at Audi stunningly combines the essence of power and emotion. The 4.2 FSI propels the coupé’s 1,725 kilograms (3,802.97 pounds) in 4.6 seconds from 0 to 100 km/h (0 to 62.14 mph) to an electronically governed top speed of 250 km/h (155.34 mph). Audi can increase that to 280 km/h (173.98 mph) upon request.
Efficiency is standard in every Audi; the RS 5 is no exception. The ultra-powerful eight-cylinder engine averages 10.8 liters of fuel per 100 kilometers (21.78 miles US mpg) - far less than its main competitors. This impressive figure is due in part to the technologies from the Audi modular efficiency platform. The engine and the entire drivetrain have been optimized to minimize friction, the oil pump operates on demand, and an energy-recovery system conserves energy during coasting and braking.
