The rumored BMW X6 //M version was spotted by our Australian fellows at CarAdvice.com.au. Just a couple of days ago, we announced that BMW has registered the X6 M trademark, which was clear sign that the sport version of the X6 is in works already.

Of course, typical BMW, the X6 M has not been officially confirmed, but judging from the spy photos, it is clear that we are dealing here with the Motorsport model. The clues? The typical M dual-exhaust and especially the more obvious side vents.

Rumors have it the the BMW X6M will be powered by a 5.0-litre V10 with 373kW and 520Nm of torque, even though we believe that a twin-turbo engine will be more suitable for the job. The 4.4 V8 Twin-Turbo can be the ideal choice. The car already weighs around 5,000 lbs and placing a heavy V10 engine in it, would not make much sense.

Time will tell again and at this point, everyone can only speculate.
