Everyone's favourite German autotuners, ABT, have wasted no time getting busy with the next-generation Audi RS6 to once again delivering an aggressive twist on the beloved sleeper.

As is standard operating procedure for ABT, the boost comes in the form of both aesthetics and 'Power Performance Upgrades'. The latter increasing the new RS6's standard 592bhp to an impressive 690bhp by way of a reprogrammed ECU and engine management system. The exhaust - which is already one of the most raucous on the market - has also been tweaked, naturally.

After removing the limiter, ABT's take on the RS6 can now do the 0-100 km/h dash in 3.4 seconds. That's 0.2 seconds quicker than standard.

To match the ferocity under the hood, those up-tuning their RS6's are also privy to an array of external aftermarket options including skirts, spoilers, bumpers, and wheels. The current RS7 and RSQ8 models (all of which use the same 4.0-litre twin-turbocharged V8), can also be upgraded using the same performance package on the RS6 in question today.

But does the ABT once-over detract from the 'sleeper' guise that makes the RS6 so sort-after in the first place? You be the judge in the gallery below.

There's also no set price for this particular upgrade, but those keen to learn more can head to abt-sportline.com.
