2015 BMW M4 Convertible Announced

The topless and well-endowed streak continues

2015 BMW M4 Convertible Details:

  • Arrives in US showrooms late this summer
  • Powered by 425hp M TwinPower Turbo 3.0L inline-six
  • Aluminum and CFRP parts make this open M lighter than the last
  • Makes its world debut at the 2014 New York International Auto Show

We figured it was only a matter of time before BMW announced a convertible version of the M4 Coupe (considering the M3 has had a topless iteration for generations), and sure enough one is on the way, set to make its world debut at the 2014 New York International Auto Show running April 18 to 27. Since it's an M you know it'll be loaded with all kinds of sweet features, chief among them a potent power plant to press you back into your seat as the wind blows through your hair.

The M4 Convertible will floss the same high-revving "TwinPower" turbo 3.0L inline-6 M motor that's used in the latest M3 Sedan and M4 Coupe, tuned to produce 425hp and 406 lb.-ft. of torque at its peak. BMW pegs 0-to-60mph time at an impressive 4.4 seconds with the 6-speed manual gearbox, and an even more remarkable 4.2 ticks when the 7-speed M Double Clutch Transmission (M-DCT) is employed.

That M-DCT is something else, described as combining two transmissions, each with its own clutch, to make gear changes without an interruption in the flow of power. The multi-mode Drivelogic feature lets drivers choose from comfort to economy to sporty, and the M-DCT also comes with a launch control option. An Active M Differential makes sure the M4 Convertible is hooking up.

Other characteristics heightening the driver's experience include three-mode electromechanical steering (each mode offers a different level of steering assistance) and an optional Adaptive M suspension. The open M4 sports standard M compound brakes from the factory but an M carbon ceramic option is available.

Surprisingly, the M4 Convertible is some 90 pounds lighter than the topless M3 it succeeds. This is accomplished through the use of aluminum and carbon fiber reinforced plastic (CFRP) in key areas; you'll find the front fenders and hood fashioned from aluminum, while elements like the drive shaft and front strut brace are made from the composite weave.

Exterior looks reflect both performance and M heritage; go no further than the twin headlights, twin-bar kidney grille with black painted grille bars, large vent openings in the front apron and domed hood to get what we mean. On either side there are newly designed M "gills," integrated with Air Breathers that team up with the Air Curtains up front to help optimize airflow around the wheel arches. If the weather gets nasty, a retractable three-piece hardtop can keep it out.

The cabin houses a host of customary BMW M equipment details including M door sill finishers, an M driver's footrest, M gearshift lever, M-design circular instruments with white graphics, M leather steering wheel with chrome trim, color contrast stitching and electroplated-look shift paddles (M-DCT gearbox only). Motorsports touches also can be found in the forward bucket seats (pimped out with neck warmers) and leather multifunction steering wheel.

While it debuts in New York in a couple weeks, the BMW M4 Convertible won't hit US showrooms in summer 2014 - just in time for topless weather!
