German car manufacturer Audi has just released official details about the upcoming S6, in both sedan and wagon versions, S7 and S8, ahead of the Frankfurt Motor Show in September, which will be powered by the 4.0 liter V8 petrol engine, developed in partnership with Bentley.
The new S8 takes its power from the 4.8 liter twin turbo V8 unit, which is replacing the naturally aspirated 5.2 liter V10 of its predecessor, delivering 69 BHP more to a peak of 513 BHP and 479 lb-ft of torque, between 1.700 and 5.500 rpm, accelerating from 0 to 62 mph in just 4.2 seconds with a top speed limited to 155 mph, like all S models. The luxury saloon weighs 1975 kg and burns 10.2 liters/100km (27.7 US mpg) in a combined cycle, a 6.3 mpg improvement.
The new S6 and S7 are powered by the same 4.8 liter twin turbo V8 engine, delivering 420 horsepower and 406 lb-ft of torque, offered between 1.400 and 5.300 rpm, mated to a seven-speed dual clutch transmission and Audi’s Quattro system, but as an option, customers can choose a sport rear differential. According to the automaker, the 0 to 62 mph sprint takes 4.8 seconds for the S6 and 4.9 seconds for the S6 Avant and S7.
Fuel consumption for the S6 and S7 has also been improved by 25 percent and the models are using the cylinder deactivation technology, which is coming with Active Noise Cancellation when running in four-cylinder mode), and the start/stop system, all of these leading to 9.7 liters/100km (24.25 US mpg) for the S6 and S7 and 9.8 liters/100km (24 mpg) for the S6 Avant.
The Audi S6 sedan, S6 wagon, S7 and S8 models will be officially presented at the Frankfurt Motor Show in September, when details like the price or exact release date will be announced.
