BMW released official details and pictures of the M4 Convertible a few days ahead of the car’s world debut at the New York Auto Show. As you’d expect, the car is virtually identical to the M4 Coupe, apart from the roof, which is a folding hardtop, adding the sensation of alfresco motoring to the M4’s poise and balance and speed.

Compared to the previous convertible 3-Series, the new roof arrangement used in the BMW M4 Convertible features a number of design improvements that reduce noise levels for a much quieter interior ambience. Hopefully, the materials are improved as well, as the old model’s rubber seals used to go rather quickly, making an unpleasant noise when you operated the roof.

The M4 Convertible’s three-piece roof converts in 20 seconds, and can also be lowered when the vehicle is travelling at speeds of up to 18 km/h (approx. 11 mph).

The rest of the car is standard M4, which means it is a brilliant sports car. You get a turbocharged inline-six engine developing 425 horsepower and 406 lb-ft of torque. Just like the Coupe, it can be mated to either a 6-speed manual or 7-speed M-DCT transmission. Zero to 60 mph takes 4.4 seconds with the 6-speed manual, and 4.2 seconds with the 7-speed M Double Clutch Transmission. Top speed is limited to 155 mph.

There is standard Active M Differential optimizes traction and electromechanical steering system with three settings (COMFORT, SPORT and SPORT+). The Adaptive M suspension, also with COMFORT, SPORT and SPORT+ modes, is optional.

Compared to the normal 4-Series Convertible upon which the BMW M4 Convertible is based, the M car looks a lot more athletic and desirable thanks to a full M body kit with large air intakes, spoilers, skirts, skirts, and diffuser, and M wheels. Pricing and specs of the car will be released closer to launch later in the year.
