2013 Audi S7 (2011 Frankfurt Auto Show)

The Audi S7 The Audi S7 uses the same engine as the S6 and S6 Avant, the new 4.0 TFSI with 309 kW (420 hp) and 550 Nm ( lb-ft) of torque. The twin-turbo V8 accelerates the five-door coupe from 0 to 100 km/h ( mph) in 4.9 seconds, and top speed is limited to 250 km/h ( mph). The cultivated eight-cylinder, which uses Audi’s “cylinder on demand“ technology under part load, consumes on average just 9.7 liters of fuel per 100 km ( US mpg). Much of this groundbreaking efficiency can be attributed to the lightweight body. A hybrid aluminum construction, it weighs roughly 15 percent less than a comparable all-steel body. Lightweight components include the long rear hatch that opens and closes electrically as standard.
