2012 Audi S7 Sportback
The most potent member of the A7 Sportback family to date debuts a new 4.0-liter twin-turbocharged TFSI V8 engine that will also find its way under the hood of a variety of VW Group models including Audi’s own S6 and even Bentley’s Continental series.
The force-fed eight-cylinder motor generates an output of 420-horsepower and a peak torque of 550 Nm (405.7 lb-ft), allowing the S7 to complete the 0-100km/h (62mph) sprint in 4.9 seconds and reach an electronically limited top speed of 250km/h (155mph).
The V8, which uses the German firm’s “cylinder on demand” technology under part load, consumes on average an estimated 9.7 liters of fuel per 100 km (equal to 24.3mpg US).
A seven-speed S tronic dual clutch transmission and Audi’s quattro permanent all-wheel drive system with a self-locking center differential and torque vectoring, transfer power to the ground.
