Supercharged Audi A6 Uses Some Unusual Parts to Produce 430 Wheel Horsepower

This unassuming, sleeper of an Audi A6 is quite quick, but it’s also stock-looking and supremely comfortable.

The Audi A6 has long been a popular choice in the luxury sedan segment, offering up plenty of technology, performance, and comfort in a stylish package. Of course, those that crave more performance can opt for the S6 or RS6, while the A6 is more of a plush, soft-riding alternative. However, that doesn’t mean that you can’t give the Audi A6 a serious boost in that regard, and that’s precisely what the owner of this one did – leaving quite an impression on David Patterson of the YouTube channel, That Dude In Blue.

Patterson has driven all kinds of modified rides in his years on the social media platform, but he admits that he has a special place in his heart for sleepers – a category that this Audi A6 certainly falls in. On the outside, it looks like a bone stock example with zero obvious modifications  – not even a clue that this car has been upgraded in significant and in some cases, strange ways underneath its unassuming skin.

This particular car has the optional supercharged 3.0-liter V6 that made a respectable 333 horsepower in factory form, but that wasn’t quite enough for its owner, Nate. Thus, he added a smaller supercharger pulley to up the boost, a stage 2 APR ECU upgrade with an E85 tune, and strangely enough, a cold-air intake designed for a Ford F-150. Regardless, the results are indeed impressive – this A6 now makes 430 horsepower at the wheels, and is capable of ripping off quarter-mile passes of 11.8 seconds. It’s truly a fantastic example of a sleeper, as well as a proper S4 clone in many regards.

The beauty of this combination is that Nate isn’t giving up his car’s comfortable ride or relaxed nature while also gaining that performance. Given the fact that he routinely drives long distances as a competitive golfer, that’s important, but at the same time, he can also enjoy a spirited drive when he wants to – making this modified A6 the perfect all-round daily driver.
