Here’s prove that BMW is working on a hot M-version X5 off-roader, likely to be powered by the firm’s 6.0-litre V12 taken from the 760i and delivering 438 bhp.

X plus V = M

We have been aware of a BMW X5 M prototype since it was innitially spotted in the Death Valley in July but news has been sporadic if not completely absent. Multiple rumours about the engines have been surfacing like a twin-turbo V8 (which seems to be finding its way to the next BMW M5). But it is still a safer bet that the V12 engine from BMW's 760i delivering 438 bhp will be powering the X5 M, which would still blow the 272 bhp 3.0 liter in-line six and 355 bhp 4.3 liter V8 found in the regular X5 out of the water. Proof is the 2000 BMW X5 LeMans experimental vehicle which sported the 700 bhp 6.0 liter V12 from the 1999 winning LeMans race car.

And how we can be so sure that this is the BMW X5 M and not just another X5. The two sets of twin exhaust tips are a dead give-away and the front bumper has bigger air-intakes ensuring more efficient colling of both brakes and the engine.
