BMW M3 and M4 will be released on December 12

Recently, overseas media reported that BMW will publish official pictures of the M3 and M4 on the Internet on December 12. These two new models will be publicly unveiled at the 2014 Detroit Auto Show that opened in January 2014.

After confirming the release date of the new car, the BMW official also revealed in advance a spy shot of a camouflaged test vehicle for the M3 and M4 production cars, but due to strict disguise, we cannot see the changes in the details of the two new cars. However, with the previous M4 concept car, we can experience previews of some of the sporting improvements in the design of the future M4 production car. As for the M3, it will only wait until December 12th.

In terms of power, the BMW M3 and M4 production cars will all use a 3.0-liter twin turbocharged engine, which is expected to deliver a maximum output of 430 hp (316 kW) and a peak torque of 500 N·m. In addition, M3 and M4 will also use a series of lightweight designs, but the specific weight loss has not yet been officially announced.
