Even though deliveries of the Audi RS6 have only just begun, looks like a few power-hungry owners have already got bored of its measly 600hp and 800Nm.

Enter ABT – tuner of all things German – and its ‘Power Performance Upgrades’, which consist of a reprogrammed ECU and engine management system as well as a new exhaust.

Compatible with not only the RS6, but the RS7 and RSQ8 too (all of which use the same 4.0-litre twin-turbocharged V8), the ‘ABT Power S’ kit adds almost 100bhp and 80Nm, giving 700hp and 880Nm.

The only way to move your family and possessions around more quickly is by getting an E63 AMG and sending it to Brabus.

ABT claims a top speed of 320km/h, with the limiter removed of course, and a 0-100km/h time of less than 3.4secs, which is 0.2secs quicker than standard.

How much? ABT isn’t telling, but the fact the upgrade doesn’t require many actual hardware changes means your average RS6 owner probably wouldn’t balk at the cost. There are of course skirts, spoilers, bumpers and wheels on offer too, but we’d leave those well alone for maximum stealth.
