The high-performance drop-top follows in the footsteps of the new M3 Coupe and M3 Sedan. Like its solid-roof counterparts, the Convertible is powered by a 4.0 liter V8 producing 420 horsepower and 295 pound-feet of torque. The drop-top's main competitors are the Audi RS4 Convertible and the Mercedes CLK 63 AMG.

BMW is also using the convertible to debut its seven-speed M DCT dual-clutch transmission. The seven-speed system promises shifting as smooth as a conventional automatic and faster than a manual gearbox or SMG transmission. Of course, customers can still opt for a regular six-speed manual.

Apart from the body structure, only the doors, the retractable hardtop, the luggage compartment lid, the windows and the rear lights come from the standard open-air version of the BMW 3-Series. The range of brand-new body components, therefore, is virtually the same as in the M3 Coupe.

The rear axle V-bars already featured on the Coupe and Sedan to provide reinforcement have been extended all the way to the side-sills. This configuration enhances chassis stiffness around the rear axle -- critical for a convertible performance car.

Like the other M3 models, the Convertible has high-performance brakes to keep the car's massive power in check. The rotors measure 14.2 inches up front and 13.8 inches at the rear.

As an option, the new BMW M3 Convertible may be equipped with EDC Electronic Damper Control. Adjusting damper forces electrohydraulically, EDC optimises both the car's vertical vibration behaviour as well as its yaw and roll motion in bends and its dynamic axle load distribution when applying the brakes and when accelerating.

The new BMW M3 Convertible is available with a choice of four special M metallic paintwork colors: Melbourne Red metallic, Jerez Black, Interlagos Blue, and the M5/M6-sourced Silverstone.
