While the four-door M3 is a great car, its the sleeker two-door M4 that will be stealing our attention come next summer. Just like its four-door sibling, the M4 will feature the inline turbocharged six-cylinder that produces a maximum output of 425 hp and 431 lb-ft of torque. When it arrives at dealers you'll be able to get the M4 with a throttle-blipping 6-speed manual or a 7-speed M Double Clutch Transmission which can get the car from 0-60 in just 3.9 seconds. The car also has the carbon-fiber-reinforced plastic roof of the M3 and also gets an integrated rear spoiler made from the same lightweight material. The M4 will hit showrooms alongside the M3 in the summer of 2014.
