If the droptop M4 didn't mean business before, it does now.
Hamann has followed its upgrade for the M4 Coupe with something just as tasty for the BMW M4 Convertible. As you can see, the exterior, finished in Sakhir Orange, gets a body kit made up of a front spoiler, new side sills, rear diffuser, seven-piece rear apron and optional carbon-fiber hood. A range of alloys, dubbed the Formula series, Anodized, Anniversary Evo, Evo Black, and Evo Hyper Black, and Hamann professional, also form part of a new styling package.
Interior mods are limited to sport pedals and aluminum foot rests, while thanks to a power module and sport exhaust system with 90-mm tailpipes and carbon tips, output has been boosted from 425 hp and 406 lb-ft of torque to 517 hp and 516 lb-ft of torque.
