Power boosting on the 2.5 liter TFSI unit comes in two stages, with the first bump being a substantial 80 horsepower over the series 340 PS (250 kW / 335 bhp) and 450 Nm (332 lb-ft) of torque for a new output level of 420 PS (309 kW / 414 bhp).
Abt Sportsline goes even further with an output offering 470 PS (346 kW / 464 bhp) and 630 Nm (465 lb-ft) of torque.
Both editions also get their V-max limiter lifted to 285 km/h (177 mph).
The tuner offers various 19-inch light-alloy rims on the RS3, wrapped in tires sized 255/30R19 for the front wheels and 225/35R19 at the back.
