Audi has unveiled their latest iteration of the S6 and S6 Avant, and the mid-size sports sedans look to continue the engine downsizing trend, moving from a 5.2L V10 to a 4.0L V8 with twin turbochargers making 420 horsepower and 405 lb-ft of torque.
The new S6 will sprint to 60 mph in 4.8 seconds (while the Avant does it in 4.9) while consuming only 24 mpg (a figure we assume is on the highway). Power is transmitted to all four wheels via Audi’s S-tronic dual clutch ratio with seven cogs, and the active sport differential will also be an optional, similar to the S4.
An air suspension, 19″ wheels and a noise cancelling system (to keep the cabin silent) are all standard. No word on pricing, or North American availability, but we’d assume that the sedan is a shoo-in, while the Avant will sit this one out.
