A late prototype of the 2020 Audi Sportback was spotted in and around the Nurburgring during some high-speed testing, showing off bits of its final production bodywork.

Audi Sport’s upcoming four-door coupe looks like it’s wearing the final production front end, just like the last RS6 tester we showed you a week ago. The more aggressive face is combined with a slightly wider bodywork and a rather large set of wheels, which create the necessary clearance for the huge brakes.

The 2020 RS7 is going to adopt a more angular black front grille with bigger openings, allowing more air to flow through and cool the powertrain. Speaking of which, the reports talk about either a twin-turbo V8 with around 650hp or the 670hp plug-in hybrid powertrain of the Porsche Panamera Turbo S E-Hybrid.

Audi’s head designer reportedly confirmed that Audi plans to offer the RS7 with both powertrains, with the plug-in hybrid to sit on top of the range with 700hp.

Neck-breaking performance, no matter the powertrain

We still can’t tell for sure if the specific Audi RS7 test uses the aforementioned electrified powertrain since it appears to not have a second flap for charging. With that said, ignore the roll cage as well, as it’s there only for safety reasons during development.

Given that the outgoing Audi RS7 Performance is capable of scoring 3.7 seconds for the 0-60mph run, it’s safe to expect that the new model will drop that time into even more neck-breaking territory, partly thanks to improvements made to the Quattro all-wheel drive and its electronics.

Just like the upcoming Audi RS6, the 2020 RS7 will feature a sportier atmosphere in the tech-laden cabin, with bucket seats, contrast stitching and the increased use of Alcantara. Model-specific drive modes are also a given.

The new Audi RS7 will go against models like the BMW M5, as well as the Mercedes AMG GT 4, which is also rumored to get a range-topping plug-in hybrid version.
