Ado X Performance’s Audi RS6 C8 Sedan Is an 850 HP BMW M5 Killer

Ado X Performance’s Audi RS6 C8 Sedan

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.

B8 Audi A4 Avant Gets S4 Powertrain Swap for Max Performance

B8 Audi A4 Avant S4 Powertrain Swap

This Audi A4 Avant S4 clone mimics something that wasn’t sold in the U.S., and the results are quite impressive.

It may seem hard for many of us to believe, but 2009 was a pretty long time ago at this point – 14 years, to be exact. That’s an eternity in the automotive world, when things change quickly and technology advances at a rapid rate. However, there’s still plenty to like about Audi vehicles produced during this era, with their simple, tasteful styling that’s held up nicely over the years, as well as some compelling performance models. However, there was one ride in particular that wasn’t sold in the U.S. – the B8 S4 Avant, so a fellow named Mark Jackson set out to create his own by starting out with a 2009 Audi A4 Avant, a build that was recently featured in a video from Deutsche Auto Parts.

This Audi A4 Avant came from the factory with a turbocharged 2.0-liter inline-four cylinder under the hood, which generates a reasonable 211 horsepower and 258 pound-feet of torque. It’s a decent engine for this platform, but it’s no hot rod by any means, leaving enthusiasts like us – and Jackson – wanting more. Thus, he decided he was going to build his own version of the B8 S4 wagon that America didn’t get.

Jackson set out to find a suitable donor, and wound up doing just that in the form of a wrecked S4. He harvested that car’s supercharged 3.0-liter V6, six-speed manual transmission, and differential, but he didn’t just leave the new motor alone, either. Instead, he added some performance extras such as an Integrated Engineering Stage 2 Double Pulley tune, a smaller supercharger pulley to ramp up boost, and a CTS crank. The result, according to Jackson, is that his wagon now makes around double the horsepower of the engine that it replaced.

Amazingly, Jackson points out that this job was actually pretty simple and straightforward, given the fact that the A4 and S4 share so much in common. His goal here wasn’t just to make his wagon faster, however – rather, he wanted to ensure that the average person couldn’t tell that this isn’t a factory B8 S4 Avant, so he even went to the trouble of swapping over the entire interior and other bits and pieces. Needless to say, it’s an amazing finished product, and one that makes us want to go out and build our own hot rod wagon.

R8 Comparison: 2023 R8 GT vs the Cheapest Audi R8 You Can Buy

2023 R8 GT vs 2009 R8 V82023 R8 GT that is limited to just 333 examples worldwide and costs a little more than $250K. It has a V10 that fires 602 horsepower to the rear wheels via a 7-speed dual-clutch automatic transmission. It is a desirable model that collectors will seek out for years to come. But collectability aside, is it a better sports car than say a 2009 V8 R8 with a manual transmission? What if you consider that the older R8 can be had for roughly a quarter of the price of the new R8 GT?  Does the R8 GT justify its high price compared to even a brand new R8 V10 Performance RWD that is about 100 grand cheaper?

That is what the folks at Throttle House are attempting to determine in their latest video. In one corner they have a 2009 R8 V8 that can be had for $63,995. In the other corner is the 2023 R8 GT wearing a $253,290 MSRP. Neither car is what you would call cheap. But for the price of the R8 GT you could buy the older R8 plus a new S8 performance sedan, AND a new SQ5 for running to the shops. The R8 GT would have to be pretty darn special to justify the price. Well, it is special, but is it special enough?

2017 Audi TT With Turbocharged VR6 Swap Churns Out 700 HP

2017 Audi TT With Turbocharged VR6

A turbocharged VR6 swap makes this 2017 Audi TT incredible quick, but it also looks the part with an array of upgrades.

Now on its way to the proverbial automotive graveyard, the Audi TT certainly gained its fair share of fans over the years, largely thanks to its concept car-like styling and solid performance. For some, however, you can just never have enough power underhood, and that includes the owner of this wild 2017 Audi TT. Rather than spend the time and money upgrading this car’s original turbocharged 2.0-liter inline-four cylinder powerplant, they wound up replacing it altogether with a larger turbocharged 3.6-liter VR6 built by R-Performance and AW-Racing, and the results are quite amazing.

Those companies provided what the owner calls their Stage 2 setup for this particular powerplant, as well as a titanium exhaust and multiple tunes so that he can run different fuels when so desired. On 98-octane, the combination of good for around 600 horsepower, while adding 100-octane helps it make an impressive 740 horsepower, which flows to the wheels via a built DSG DQ500 gearbox.

In terms of how this translates to performance, the owner claims that his swapped 2017 Audi TT will do 0-62 mph in the sub three-second range, and go from 62-124 mph in 4.9 seconds – impressive numbers, indeed. To help manage the car’s newfound power, he also added a set of Bilstein B16 dampers, Eibach sway bars, and a braking system that consists of six-piston calipers and PFC discs up front, as well as 334mm ventilated discs out back.

However, this 2017 Audi TT isn’t just chock full of mechanical upgrades – it also features a full TT RS body kit, along with a large rear wing, Rieger diffuser, and a front splitter and side skirts from Maxton Design. The car rolls on a set of 19×8.5-inch Motec Ultralight wheels wrapped with Pirelli rubber, though the interior was left alone, save for a set of DSG shift paddles.

It’s a tantalizing package for certain, and one that’s actually for sale right now on the Unique Cars For Sale In Europe Facebook page. Problem is, the car is located in Warsaw, Poland, which isn’t great news for U.S.-based buyers. Regardless, it’s a spectacular machine worth taking a closer look at, with an engine swap that makes it truly unique as well.

2023 Audi RS 3, BMW M2 Battle It Out for Small Performance Car Glory

2023 Audi RS 3 vs BMW M2

The brand new BMW M2 may be significantly more powerful, but it’s also less satisfying than the 2023 Audi RS 3.

These days, we live in what one could call the golden age of automotive performance, a time when one can buy all sorts of fast machines. This list covers the entire spectrum of vehicle types, whether we’re talking about traditional high-performance muscle cars and exotics all the way up to pickup trucks and large SUVs, and pretty much everything in between. Those seeking a small performance car with a bit of luxury also have some fantastic vehicles to choose from, with the 2023 Audi RS 3 and BMW M2 being among the best of the best, which is precisely why Throttle House pitted them against each other in a number of ways recently.

The BMW M2 has the benefit of being completely new, following a full redesign for the 2-Series on which it’s based. It’s powered by a twin-turbocharged 3.0-liter inline-six developing 453 horsepower and 406 pound-feet of torque, which flows to the rear wheels via either a six-speed manual or an eight-speed automatic transmission. Right off the bat, Throttle House notes that the manual “feels cumbersome” and the automatic “is dim-witted half the time,” which isn’t a good start.

2023 Audi RS 3 vs BMW M2

In the other lane, we have the 2023 Audi RS 3, which takes a different approach with its turbocharged 2.5-liter inline-five that sends 401 horsepower and 369 pound-feet of torque to all four wheels via a seven-speed dual-clutch gearbox. It tips the scales at around 3,600 pounds, however, which is notably less than the M2’s curb weight of just over 3,800 – quite interesting given the fact that the latter model doesn’t have to deal with the extra weight that AWD components add.

2023 Audi RS 3 vs BMW M2

TH notes that the 2023 Audi RS 3 is a “much more rewarding drive,” but aside from simple driving pleasure, what matters here is how the two stack up in terms of performance. To answer that question, we start out with a series of drag races, which the Audi kicks off with a win thanks to its massive traction advantage. In a roll race, the M2 uses its power advantage to motor ahead and take the win in that style of straight line test, though the car is clearly a bit more difficult to drive in that manner, too.

Out on the track, the RS3 managed a best lap time of 1:11.93, making it the 12th quickest car TH has tested to date, while the M2 wasn’t terribly far ahead at 1:11.19 – quite impressive given the fact that the Audi is down significantly in terms of output. At the end of the day, our hosts reveal that they would still buy the RS3 over the current-gen M2, which has seemingly taken a step back from generation-to-generation – bad news for BMW fans, indeed.
