It's been a while since we last saw prototypes of the 2013 BMW X6 facelift. Now spy photographers have caught it for the first time during cold weather testing in and around Arjeplog, Sweden.

Changes include front and rear bumper fascias, new internal headlamp design with LED DRL corona rings, redesigned kidney grilles with new slats and wider surround bezel, and new LED design tail lamps.

The petrol engines will likely carryover, but rumors suggest a new tri-turbo 3.0-liter six-cylinder diesel in a potential X6 xDrive50d could be added to the lineup. It is expected to produce 350 PS (258 kW / 345 hp) to 400 PS (294 kW / 395 hp). Stepping it up to an M treatment renders the X6 M50d with 381 PS (280 kW / 375 hp) and 740 Nm (546 lb-ft) of torque. This could enable the crossover to accelerate from 0-100 km/h in just 4.9 seconds.

The X6 facelift is expected to be launched in March this year as a 2013 model.
