Here are the first official details with the facelifted generation BMW X6, a model which will goon sale in Spring that marks the introduction of a new diesel engine under the M50d badge as part of the MPerformance Series.

This engine is a 3.0-litre inline-six diesel featuring three turbochargers which will deliver 381 HP and 740 Nm (546 lb-ft) of torque at only 2,000 rpm, but which will not be available in the USA.

The USA lineup will include the same power units as before, meaning a 4.4-litre turbocharged V8 rated at 400 HP in the xDrive50i and a 300 HP 3.0-litre turbocharged inline-six, with both engines spinning the wheels via an eight-speed automatic gearbox.

Theperformance version X6 M with its 555 HP V8 will also be available, andin this case we are talking about an M Sport Automatic transmission with six gears.

For those who can not afford the X6 M but still want some extra power, the Bavarian automaker offers the M Performance Package which will enable an extra 15 HP and 30 lb-ft of torque on the xDrive35i and 40 HP and 30 lb-ft on the xDrive50i.

Those living in Europe will have two more options apart from the recently introduced diesel producing 381 HP, and these options include two other 3.0-litre inline-six turbocharged diesels delivering 245 BHP 180 kW and 306 BHP / 225 kW on the xDrive30d and xDrive40d respectively.

In terms of appearance the 2013 BMW X6 Facelift features minimal changes which can barely be spotted by looking at the headlights, the grille, the fog lamps and the LED taillight, plus the automaker added one new exterior colour (Marrakesh Brown) and two new choices for the leather interior (Vermilion Red and Ivory White).
