BMW releases its drop top version of the M4 coupe this fall. The very successful M4 has seen stuntastic sales for 2013. Naturally the M4 Convertible left tongues wagging at this year’s New York International Auto Show.

The race-inspired M4 drop top has optional twin LED headlights that accent the sport logo tattooed outside and the in, including on the double-spoke wheels. The longer M4 Convertible’s exterior design has a lot of sexy aerodynamic features like the three large front air intakes and the cool new M gills with air breathers. Front air curtains also direct airflow around the wheels.

The 2014 M4 Convertible weighs only about 4,000 lbs, dropping 90 lbs with the instruction of aluminum components and Carbon Fiber Reinforced Plastic (CFRP). Aluminum was used to construct the chassis, the front fenders, and the power dome hood.  The drive shaft and the engine’s strut brace are composed of CFRP. Thanks to lightweight elements the M4 Convertible offers enhanced rigidity and supreme handling. The M4 Convertible’s lightweight design with its aerodynamic flair also enhances its class leading performance.

The M4 drop top features a 3 liter M4 Twin Power turbo V8 with a 0-60 mph time of only 4.4 seconds with the automatic transmission, and 4.2 seconds with the manual. The new M4 Convertible has a 40% torque increase to boast 406 lb-ft and 425 horsepower. An optional Launch Control Function allows for maximum torque to be delivered from a standing stop. The new M4 Convertible’s twin power engine has Valvetronic variable valve timing and double VANOS continuously variable camshaft timing along with High Precision Direct Injection. All three features work in tandem for smooth power delivery, prompt responses, and fuel savings. [divider]
