The German based automaker BMW is planning to introduce a powerful version of the F20 1-Series, under the M135i name, which is expected to debut next summer, in 2012, with its 320 horsepower from the N55 inline six-cylinder engine.

Besides the impressive M550d tri-turbo diesel which is expected to be launched in 2012, BMW is also planning a powerful version of the 1-Series F20 hatchback in the form of the M135i which is expected to develop a total output of 320 horsepower from the N55 inline six-cylinder engine. According to the, the new model might come under the M135i name, considering the fact that the powerful version of the 5-Series F10 diesel will be named the M550d.

The guys at also say that BMW can “squeeze” an additional 10 kW of output out of the N55 inline six-cylinder engine which would translate to a total of 320 horsepower. There’s no word yet on the transmission, performance or possible price but the German based automaker will have to decide whether it will use two-wheel or all-wheel drive on the future hatchback.

Besides the M135i and the M550d, BMW is also planning to introduce two new crossovers, the X2 and the X4, and the new 3-Series might get a GranTurismo version. The new BMW models might be officially presented to the public sometimes next year, during the Geneva Motor Show or even the Detroit Motor Show.
