Supercharger and FSI direct fuel injection are a powerful combination
245 kW (333 hp), 440 Nm (324.53 lb-ft) of torque and exemplary efficiency
S tronic and quattro drive standard; quattro with sport differential optional
Ingolstadt/Frankfurt - The abbreviation "S" stands for sports and also high efficiency - characteristic Audi features. The S5 Sportback is the top model of the new Sportback model series. The five-door coupe is powered by a highly efficient, supercharged V6 engine with an output of 245 kW (333 hp). Power is delivered to the wheels via the seven-speed S tronic and quattro drive; the innovative sport differential is available as an option.

The Audi S5 Sportback is powered by a three-liter V6 with a mechanically driven supercharger. The supercharger sits in the 90 degree V formed by the banks of the cylinders and produces up to 0.8 bar of pressure. Two downstream intercoolers lower the temperature of the compressed intake air for improved filling of the combustion chambers.

The six-cylinder unit, which displaces 2,995 cc, embodies the Audi philosophy that performance and efficiency are not mutually exclusive but rather complement each other perfectly. The engine delivers a constant 440 Nm (324.53 lb-ft) of torque between 2,900 and 5,300 rpm. The S5 Sportback sprints from zero to 100 km/h (62.14 mph) in only 5.4 seconds (provisional figure) and accelerates up to an electronically governed top speed of 250 km/h (155.34 mph). The spontaneous response, the powerful thrust and sonorous sound make for a thrilling driving experience. More (http://www.audizine.com/news/news.php?nid=137)
