AC Schnitzer will be showing us their BMW 4-Series Coupe at the Essen Motor Show which starts tomorrow but we have kindly been given the first set of pictures of this new tuned ride. The black diffuser looks properly epic and the subtle roof spoiler is actually not that subtle. It changes the whole profile of the car and in a very good way. Not sure on performance numbers yet but we will find out tomorrow. Damn this looks good!
