Well first off it has the old N54 motor with twin turbos , the option for a DCT automatic transmission. It comes tuned with a warranty from BMW with an extra 20 hp and even more torque. It also has the over boost function which bumps the torque up to 370 for about 7 seconds. Comes with its own front and rear bumper and side skirts( similar to an Msport) upgraded interior Msport wheel, shifter and ebrake and black headliner, It also comes with 313 wheels which are pretty sick. Think I covered most of it.
Oh yeah and of course the BMW performance exhaust.
