Ado X Performance’s Audi RS6 C8 Sedan Is an 850 HP BMW M5 Killer
This custom built, one-off Audi RS6 C8 sedan is something that the German brand doesn’t make, but probably should.
The Audi RS6 has been on sale for a while now, but for its past two generations, has only been offered in Avant – or wagon – form. While the RS6 Avant is certainly an amazing vehicle that lives in a very niche space with little competition, many have pined for a proper sedan variant – something to truly take the fight to the legendary BMW M5. However, those that have long desired to see a super high-performance version of this particular model can now get it from a company called Ado X Performance, which has created this – a proper Audi RS6 C8 sedan, which was recently featured in a video from the YouTube channel Auditography.
As one might imagine, this build started life as a regular old A6 sedan with the 3.0-liter TFSI powerplant, but has since been treated to a complete RS6 transformation in every department. That includes its body kit, which came straight from Audi and was covered in a super attractive custom shade dubbed Cristal Blue. The Audi RS6 C8 sedan sits on a set of custom-calibrated KW V4 coilovers, and rolls on two-piece 22×10.5-inch BBS wheels.
Inside the cabin, this sedan utilizes the factory pieces from an RS6 Avant, along with some custom carbon fiber bits to make it even sportier. However, the real story lies under the hood, where it has ditched its old powerplant in favor of the RS6’s twin-turbocharged 4.0-liter V8, which has been treated to a bevy of upgrades including a Stage 3 ECU remap, a Wagner intercooler, a new intake system with larger turbo inlets and an enlarged housing, as well as three-inch downpipes.
The result of those upgrades is an impressive 854 horsepower and 828 pound-feet of torque, which is far more than the RS6 Avant’s factory ratings of 621 horsepower and 625 pound-feet. It’s also enough to move this 4,140-pound sedan from 0-62 in just 2.4 seconds and up to 223 mph if you keep your foot planted long enough. While it’s unclear if Audi ever plans to make an RS6 sedan again – after all, it is moving into the world of electrification – it’s nice to know that at least one exists, and it’s a darn good one at that.
