BMW M GmbH, previously known as BMW Motorsport GmbH, is the racing subsidiary of BMW initially created to facilitate the company’s Motorsport program during the 1960s and 1970s.
It launched its first production car almost 35 years ago, and has recently revealed its new Concept M4 and will be unveiled at the 2014 Detroit Motor Show in January. It represents a split with the M3 - that nameplate will be reserved for four-door models - and will eventually see the introduction a an M4 cabriolet. In either bodystyle, it will be armed with a 3.0-litre twin-turbocharged straight-six, producing 450bhp and 480lb ft of torque. This will hustle the 1500kg M4 to 62mph in 4.5 seconds and onto a 155mph limited top speed. It will only be available with M’s seven-speed dual-clutch transmission.
