The BMW M4 Coupe and the M3 Sedan will soon be joined by a new family member - the 2015 M4 Convertible. Similar to its siblings, the 2015 M4 Convertible is powered by the TwinPower Turbo 3.0 liter inline-six engine. The new convertible is set to make its global debut at the 2014 New York International Auto Show on April 18.

The front of the 2015 BMW M4 Convertible is designed with powerful contours that give the vehicle a strong expressive look. It is equipped with a twin headlight arrangement with the optional LED technology. Situated between the headlights, the vehicle sports a black painted twin-bar kidney grille. The front apron of the convertible is designed with three air intakes to supply cool air to the engine and brakes.

The 2015 BMW M4 Convertible weighs 1,839kg, about 41kg lighter than its predecessor - the M3 Convertible. This is due to the use of aluminum for the front fenders and hood. Moreover, the chassis of the convertible is also made from lightweight aluminum.
