Story

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.

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.
