ABT's relationship with Audi has been a match made in heaven ever since the large-scale tuning firm started increasing the power outputs of the Ingolstadt-based brand's cars in the early 90s. With its heavy influence in the world of motorsport, the customization company has been able to develop technology that takes cars from the VW Group to the next level.

One of its most recent projects is the Audi RS6-S, based on the C8 generation of the mid-size performance wagon. Thanks to footage and imagery taken by Auditography, we now have a rare opportunity to see this unique custom car in fine detail.

As standard, the Audi RS6 Avant uses a twin-turbocharged 4.0-liter V8 to generate 591 horsepower and 590 lb-ft torque. You might think that this is more than enough for your daily needs but if that's just too subtle, ABT will crank that up to 700 hp and 650 lb-ft. That's just one of its entry-level packages as more exclusive offerings include a tuning revision that will see it generate a whopping 800 hp.

The unit seen here is finished in Tactical Green and bears ABT's body kit, consisting of a front spoiler lip and blades, side blades, side skirts, and a rear spoiler. This is enhanced by the firm's height-adjustable suspension and anti-roll bars.

Auditography confirms that the custom wagon can sprint from 0-62 mph in 3.1 seconds based on a series of acceleration tests. That's not a bad improvement from the standard time of 3.6 seconds. Putting performance aside, we also get to see that the RS6-S has been tailored to create a sporty yet luxurious interior experience thanks to a series of custom trimmings including an ABT-branded sports steering wheel.

For the most part, the custom wagon retains its sleek and subtle appearance, unlike some of ABT's other revisions made to the car. If you have a current-generation RS6 and like what you see here, you can consider fitting the package to your car if you have no less than $47,300 to spare.
