Ronnie Fieg's KITH collaboration turned just 150 M4 Competitions into instant collector's pieces, and this is one of them — finished in Frozen Black matte over blacked-out kidney grilles and forged wheels. The S58 twin-turbo inline-six sends 503 horsepower to the rear axle alone, reaching 60 mph in 3.8 seconds with a bark that fills every underpass it meets.

Inside, KITH-badged carbon trim and red-on-black bucket seats set it apart from any other M4 on the road. Adaptive M suspension keeps it composed through the city, and an eight-speed M Steptronic snaps off shifts the moment the road opens up.
