In November, ABT Sportsline announced a special tuning package for the latest RS3 Sportback and Sedan, taking the 2,5-litre turbocharged five-cylinder engine from the stock 294 kW to a tempting 339 kW. At the time, the firm also revealed that it was working on an even more potent version.

And now the German tuner has revealed its flagship upgrade package. Dubbed the “Power R” update, the package boosts the RS3's peak output to 368 kW, with ABT promising that "improved driving dynamics" come along with the added oomph. No word yet on what effect this has on Audi's stock claimed 0-100 km/h time of 4,1 seconds.

The company also offers a suspension upgrade in the form of ABT springs and anti-roll bars, along with a “special damper setup” developed in conjunction with specialist firm, KW.

ABT Sportsline will furthermore gladly sell you a handful of exterior styling elements, including a new front skirt, updated front grille and redesigned rear skirt. An ABT exhaust system with a quartet of menacing (102 mm diameter) pipes in matte black is also available.

Other options include the ABT brake upgrade kit, fresh alloy wheels (offered in 19- or 20-inch guise) and various carbon-fibre bits and bobs for the cabin. The interior can furthermore be decked out with ABT branding on the gearshift and on the start/stop button itself.
