Audi S5 Sportback
Audi now has a really nice range of middleclass-bombers. The latest addition is S5 Sportback, and some of the facts are:
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 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.
