The Audi RS6 is one of the best options when it comes to high performance family haulers. However, while the first two generations of the RS6, the C5 (2002-2004) and the C6 (2008-2010), were available in both four-door sedan and five-door Avant bodystyles right from the factory, for the C7 (2013-2018) and the C8 (2019-present) Audi decided to offer them exclusively in Avant form.

So what happens when you prefer to drive a sports sedan? Besides opting for the rival BMW M5 and Mercedes-AMG E63 S, you can get this custom-made RS6 Sedan based on a tuned third-generation C7 model.

As you would imagine, there are a few people in the world willing to make a full conversion – including this black beast from 2018. Another example is the pictured 2013 RS6 Sedan listed for sale in Germany for €129,999 ($153,730). It was built by Ado X Performance and comes with several modifications.

The RS6 Sedan combines a green exterior with white leather in the cabin. Based on the S6 Sedan, the rear fenders are toned up to match the wide front end while the glossy-black diffuser and oval tailpipes perfectly match with the aftermarket wheels by Wheelforce.

Under the bonnet, the twin-turbo 4.0-liter V8 produces 789 hp (588 kW / 800 PS) and 1,150 Nm (848 lb-ft) of torque. For reference, the stock RS6 C7 produced 553 hp (412 kW / 560 PS) and 700 Nm (516 lb-ft) of torque, while the RS6 Avant Performance got a healthier 597 hp (445 kW / 605 PS) and 750 Nm (553 lb-ft).

This unique RS6 Sedan was presented two years ago in a video by the German automotive magazine GRIP doing heaps of donuts, revving, drag racing, and autobahn driving. You can see how easily it exceeds the 240 km/h (149 mph) mark, making us believe that it might have hit 300 km/h (186 mph) if it had less traffic. It can also be seen easily winning a drag race against the pre-facelift Mercedes-AMG E63 S.
