German tuner introduces comprehensive makeover in Geneva.
German BMW specialist AC Schnitzer has delivered such a comprehensive upgrade package for the BMW M4 it’s been given a new name. Dubbed the ACS4 Sport, the coupe benefits from a performance package that ups the turbocharged inline-six unit from 431 hp and 406 lb-ft of torque to 510 hp and 476 lb-ft. A new exhaust protrudes out the back in Racing Evo Carbon trim complete with silencer and valve control, while an adjustable racing suspension will drop the M4 by up to 40 mm.
A carbon-fiber racing body kit includes a front spoiler, front splitter, side wings, rear diffuser, roof spoiler and fixed rear wing. Carbon-fiber mirror caps and a range of alloys, including new 20-inch AC1 BiColor rims, round off the exterior mods, while the cabin has been reworked with lots of aluminum trim and a gear knob with digital display.
