The ever intuitive folks over at Auto Motor und Sport have uncovered the first details that Audi are working on a new engine for the new generation S4. The new Supercharged 3.0T FSI V6 powerplant is reported to pump out 350 horsepower and will replace the 340hp 4.2-liter V8 found in the current generation.
The new V6 engine will consume significantly less fuel than the outgoing powertrain and weight reduction further enhances the performance. A detuned 290hp version will initially debut in the A6 facelift later this year, it will also make its way to the Audi S5 and Q5 models sometime in the future.
The photos show prototypes for the new S4 and A6 facelift whilst undergoing winter testing earlier this year.
