ABT has revised its power boost program for the Audi RS6 Avant just in time for next month’s Geneva Motor Show.

It was last July when ABT's engineers came up with an upgrade kit for the Audi RS6 Avant which dialed the output of the V8 4.0-liter twin-turbo engine to a devilish 666 HP (490 kW) and 830 Nm (612 lb-ft). Later that year in October, the tuner revisited the kit and upped the ante to 700 HP (515 kW) and 880 Nm (649 lb-ft).

Now, they are back with the third iteration of their package, lifting output of the eight-cylinder engine to no less than 730 HP (537 kW) and 920 Nm (678 lb-ft), a lot more than the standard 560 HP (412 kW) and 700 Nm (516 lb-ft) coming out of Ingolstadt.

To keep it exclusive, ABT says they will only make 25 units and aside from the significant power bump the cars will come with a full body kit and 22-inch alloy wheels wrapped around in 295/25 ZR22 Dunlop tires. The high-performance wagon will also feature a custom stainless steel exhaust system, a height-adjustable spring kit and a tweaked cabin with bespoke floor mats, sports steering wheel (with LED shifting lights and shift paddles), along with red carbon fiber applications and embroidered headrests.

Further info can be found in the attached press release.
