Just a week before New York Auto Show unveiling, BMW published the first official photos of its new M4 Cabrio, the car that follows in the footsteps of the old M3 Cabrio.

As its coupe brother, the M4 Cabrio takes the sporty appearance of the current 4 Series and gives it a more aggresive stance with the help of new spoilers, side skirts, bonnet and twin exhaust pipes. The extensive weight-saving measures produce a curb weight of just 4,055 lbs – around 90 pounds less than its predecessor. Among the key contributors here are the aluminium front fenders and hood, with lightweight aluminium construction also a feature of the chassis. Extensive use is also made of a material that is both lightweight and extremely stiff, and therefore durable: carbon-fiber-reinforced plastic (CFRP).

The most important exterior change is the retractable hard-top, that can be used at speeds bellow 18 km/h (11 mph) in just 20 seconds. Inside, the M4 Coupe is just a carbon copy of the M4 Coupe, featuring leather wrapped sport steering wheel, M logos, M sill plated, M stitches and M gear-schitfer. The front seats are new and sporty, promissing good lateral support.

Under the hood, as its other performance brothers, the M4 Cabrio benefits from the same six-cylinder 3.0 liter unit, capable of delivering 431 hp and 550 hp. Coupled to the road through an M dueal-clutch gearbox, the M4 Cabrio can reach 60 mph in just 4.2 seconds and a limited top speed of 155 mph or 250 km/h. The BMW M TwinPower Turbo engine hits maximum revs of 7,600 rpm, in keeping with the typically high-revving character of M engines.

The Launch Control function also integrated into M-DCT enables optimum acceleration off the line.
The standard Active M Differential optimizes traction at the rear axle. The electromechanical steering system, meanwhile, represents a new development from BMW M and is the critical component in the link between driver and car. The integrated Servotronic function electronically adjusts the level of steering assistance according to the car’s speed, providing optimum steering characteristics at all speeds. Three steering settings (COMFORT, SPORT and SPORT+) can be selected at the touch of a button to adjust the level of steering assistance.

The optional Adaptive M suspension likewise comes with COMFORT, SPORT and SPORT+ modes. The BMW M4 Convertible is equipped as standard with M compound brakes, but customers can also order their car with even lighter and more effective M carbon ceramic brakes, which boast the additional visual highlight of gold-painted calipers.
