There is a reason why there are a few resounding names when it comes to tuning Bimmers, and also why AC Schnitzer numbers among them.
Their most recent endeavor involves the BMW 4 Series Gran Coupe, for which they have just released a kit.
Regarding the aesthetics, the aftermarket specialist did what you would expect, and so not many changes are visible. They installed a new front splitter, rear diffuser, mirror caps, a chromed front grille and protective film for the skirts. Inside AC Schnitzer installed some nice goodies like a gear knob with digital gear display or an aluminium handbrake handle.
But the build really shines on the performance department. Here, the BMW 4 Series Gran Coupe got an engine rework across the line, both diesel and gasoline. The 428i was upped from 245 Hp to 298 Hp, and the 435i was upgraded from 306 Hp to 350 Hp. As for the diesels, the 420d was raised to 218 Hp, the 430d to 309 Hp and the 435d saw its power increased to 360 Hp.
