Like the M3 and the M4, the M4 Convertible will pack 425 horsepower.

A new report coming out of Germany indicates the 2015 BMW M4 Convertible will be unveiled at next month's New York Motor Show.

BMW is keeping official details about its next droptop under wraps until its official debut but a lone low-resolution screen shot of a sales brochure leaked a few weeks ago gave us a good idea of what to expect from it.

The car pictured wears all of the telltale signs of BMW's next generation M-badged compacts: Beefy tires, large alloy wheels, aggressive bumpers and four exhaust tips integrated into an air diffuser. BMW has likely gone to great lengths to shave as much weight as possible from the regular 4-Series Convertible's three-piece retractable hard top.

As expected, the M4 Convertible will use the same twin-turbocharged 3.0-liter straight-six found in the engine bay of the M4 and the M3. Expect the six-cylinder mill to send 425 horsepower and 405 lb-ft. of torque to the rear wheels either a six-speed manual transmission or an eight-speed automatic unit. All models regardless of gearbox type will come with a limited-slip differential designed by BMW's M division.

The M4 convertible will land in showrooms across the United States shortly after greeting the show-going public in the Big Apple. Full details will emerge in the coming weeks.
