The suspension has been swapped out, and a new set of 20-inch ABT wheels are fitted over big brake discs and six-piston calipers. The 2.0-liter turbocharged engine has been tuned to produce 310 horsepower, up from 230 stock horses. That puts it pretty comfortably between the 265 horsepower in the TTS and the 360 of the TT RS. That's a fairly large gap, so it makes good sense for ABT to aim for the middle here. Of course, some people would like a bit more power, so if you bring ABT your TT RS, you can bump that one up to 470 horsepower.
