The current C7 generation Audi RS6 only comes in Avant form and is no longer available in sedan (or saloon, as our friends across the pond would say) form, as it did in the previous C6 generation. However, this Audi fan really wanted an Audi RS6 Sedan, so he decided to make one.
To make such a car, Roni Collin took a standard Audi S6 and put a wider body kit on it, to match the width of the RS6, as well as added bigger fender flares and must have put wheel spacers on to increase the wheel track. Then RS6-style a front bumper and grille were added so it could finish the look. He then fettled with the suspension a bit, to give it the sportier ride of an RS6.
But, most importantly, he upgraded the 4.0 liter twin-turbocharged V8 to make 580 hp and 656 lb-ft of torque, which is actually a bit more power than the standard RS6 Avant, which makes 560 hp. It’s also a lot more torque, as the stock RS6 Avant makes 479 lb-ft. All that extra power allows it to get fro 0-60 mph in 3.7 seconds, around the same time as an RS6, so job well done.
However, we wonder if he upgraded the gearbox at all, a very important part of upgrading an S6 to RS6 levels of power. The stock Audi S6 uses Audi’s seven-speed S-Tronic dual-clutch automatic transmission and the RS6 uses the familiar ZF eight-speed automatic and there’s a very good reason for the difference. The Audi S6’s dual-clutch gearbox can’t handle the torque of the RS6’s more powerful engine. Any more torque than the S6 already has can severely damage the S-Tronic ‘box. So a lot of S6 owners who’ve tuned their engines have had very serious issues after a few miles. So, hopefully, he managed to do something to that S-Tronic trans.
After the power pump, Collin added a Milltek decal exhaust, black 20″ Rotiform HUR wheels and painted it in Audi’s Mochalatte paint. It looks pretty damn good. I love that color with the black wheels. While it’s not technically an RS6, it’s the closest you’ll get to a C7 RS6 Sedan.
