Audi has officially disclose the 2011 Audi RS 3 Sportback. The RS 3 Sportback is powered by a turbocharged 2.5L five-cylinder engine that puts out 340 horsepower and 331 lb-ft. of torque. The engine is mated to a seven-speed S Tronic dual-clutch transmission and the quattro all-wheel-drive system.On the outside the RS 3 is distinct from the lesser powered A3 models thanks to its xenon headlights, and larger front air intakes, prominent sill panels and a large roof spoiler. Inside the sport seats are upholstered in Fine Nappa leather with silver contrasting stitching and the leather multifunction sports steering wheel is flat-bottomed.
The 2.5-liter engine in the RS 3 Sportback will thrill passengers thanks to its huge pulling power and its ravenous revving up to 6,800 rpm. The guttural roaring and growling, backed by the signature rhythm of the five-cylinder firing order make up the classic Audi soundtrack. A sound flap in the exhaust branch intensifies the sound even further. The flap is controlled via the standard Sport button, which also varies the engine response.
The 2.5 TFSI delivers 250 kW (340 hp) from a displacement of 2,480 cc: a specific power output of 100.8 kW (137.1 hp) per liter. The maximum torque of 450 Nm (331.90 lb-ft) is readily available at the low end of the rev range, around 1,600 rpm, and remains constant up to 5,300 revolutions. These general parameters yield excellent acceleration and elasticity values.
The large turbocharger generates up to 1.2 bar of boost pressure. The intercooler downstream achieves an efficiency rate of over 80 percent. Like all Audi gasoline turbos, the 2.5 TFSI combines turbocharging technology with FSI direct injection. The marriage of these two technologies facilitates a high compression ratio (10.0:1) along with a correspondingly high efficiency ratio. Flaps in the intake tract mix the air as it flows in. The two camshafts, each adjustable by 42 degrees of crankshaft rotation, also enhance the efficiency of the mixture formation.
Powerful five-cylinder engines have a long legacy at Audi. In the 1980s, racing cars and production cars used them to edge out the competition. Even the first Audi RS model, the 1994 RS 2, had a five-cylinder engine. The 2.5-liter unit, already part of the TT RS specifications, now redefines the state of the art, having recently been named "International Engine of the Year" by a high-ranking jury of automotive journalists.
