A report by the Automobile Magazine claims that there'll be an even more powerful version of the upcoming BMW M135i.

The M140e will use a modified version of the engine found in the front-wheel-drive M135i but as the 'e' in the name suggests the car will have electric assistance.

The turbocharged 2.0-litre petrol engine Automobile Magazine reports will have water-injection technology (same tech found in the hard-core M4 GTS).

That petrol unit will do the heavy lifting providing 220 kW and an electric motor will provide 80 kW for a total system output of 300 kW and 500 Nm of torque. The M140e will be a Plug-In Hybrid, with an electric range between 80 and 110 kilometres.

The car will come as soon as next year, the report claims.

BMW M Boss, Marcus Flasch told Top Gear that there wouldn't be a 300 kW version of the M135i xDrive. He suggested that the M2 will take on the hot hatches in the 300 kW club, like the RS3 and the A45.
