The BMW X4 has been spied in production guise once again, this time wearing slightly less camouflage than on previous occasions.

It will be fully revealed in January at the 2014 NAIAS in Detroit and in terms of design will basically be a smaller X6 riding on the X3 platform. These recent spy photos depict a prototype featuring less disguise and we also get the opportunity of having a look at the X4 with the M Sport package.

Engine choices will include the familiar 2.0-liter 4-cylinder TwinPower Turbo with 240 bhp (179 kW), a 2.0-liter 4-cylinder diesel with 184 bhp (137 kW) and a TwinPower Turbo inline-six outputting 300 bhp (224 kW) and a maximum torque of 406 Nm (300 lb-ft).

The production-ready model will follow a concept showcased by BMW earlier this year during the Shanghai Motor Show. The differences between the two won't be that significant but the car which will reach dealerships will be slightly toned down.
