BMW tuning specialist AC Schnitzer has unveiled a comprehensive aftermarket program for the BMW 4 Series Gran Coupe. Underhood, an array of performance upgrades are available ranging from the BMW 420i that now delivers 245 hp to the 435i that's rated at 360 horses. In line with the added grunt comes a throatier soundtrack thanks to two chromed twin-tailpipes that emit a selection of exhaust notes dependent on the driving mode selection.

Improved handling and ride comfort comes from a sport suspension that lowers the 4er by up to 25 mm, and an adjustable racing suspension that drops it by as much as 40 mm. Enhancing the exterior, AC Schnitzer added a front spoiler, rear diffusor, carbon mirror covers, and chromed-out front grille, while the cabin comes with an aluminum handbrake handle, a gear knob with digital display, and aluminum pedal set. Completing the package is a range of alloys available in a host of finishes and colors.
