The German firm has developed two power kits that work on modified ECUs boosting output to 370PS and 460Nm (339 lb-ft) in Stage 1 form, and 400PS and 480Nm (356 lb-ft) in Stage 2 trim.
....Just the power upgrades? Surely Abt did some suspension tuning too - and from the look of it, there are different "bumpers" front and back as well.
Anyways, voted.
