Audi RS4 Avant Spied, Likely Packs Electric-Turbo V-6

For hauling cargo as quickly as possible, the new S4 Avant isn’t the top banana in the Audi stable. As these spy photos from Germany show, the Audi RS4 Avant is under development. While little has been confirmed officially, reports suggest that RS4 will use a new electrically turbocharged V-6 engine.

Design-wise, this Audi RS4 Avant prototype hews pretty close to the look of the S4 Avant. Notable differences include larger slotted brake discs, as well as giant twin exhaust tips in place of the S4’s quad-tip setup

Yet whereas the S4 extracts 354 hp from a 3.0-liter turbocharged V-6 engine, the Audi RS4 should produce closer to 480 hp. As we reported previously, the RS4 will likely use an electrically turbocharged 3.0-liter V-6, producing at least 480 hp with significantly less lag than traditional turbo designs. All-wheel drive will be standard. The new engine is also reportedly slated for use in the new Audi RS5 coupe.

The Audi RS4 Avant has not been sold in the U.S. market since the 2008 model year, but there’s still a small chance the new car will make it here. According to Autocar, Audi is considering re-introducing an RS4 sedan, which would be targeted for the sedan-friendly markets of the U.S. and China.

Autocar also says the Audi RS4 Avant will debut before the end of 2016, which means it could be storming autobahns by this time next year. We’re eager to see just how this car stacks up against its key rivals, which include the BMW M3 and Mercedes-AMG C63 S. For now, take a look at the wild RS4 prototype in the gallery below.
