Audi S5 Sportback
From Audi press: 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.
The supercharged V6 unit consumes only 9.7 liters (provisional figure) of fuel per 100 km (24.25 US mpg) on average – a top figure in this performance class.
The leading position of the S5 Sportback is further underscored by its drivetrain technology. The top model comes standard with the seven-speed dual-clutch S tronic transmission and quattro permanent all-wheel drive with a slight rear wheel bias. Optionally available is the sport differential.
The high-end rear-axle differential transfers the forces at the rear axle between the wheels as needed for even greater dynamism and stability.
The Audi S5 Sportback has a sports-tuned chassis. The S-design 18-inch cast aluminum wheels are shod with 245/40 tires. Wheels up to 20 inches are available as options. The black brake calipers are emblazoned with S5 emblems. Servotronic speed-sensitive steering is also standard, with dynamic steering optionally available. A strut brace provides the front section of the car with additional rigidity.
