While the notion of an M-tuned SUV may have seemed inconceivable just a few years ago, the BMW X5 M and X6 M are by now a reality. And it's already been hinted that the M-powered SUV family is set to gain a new diesel-powered member.
BMW has now released a second clip showing an X6 equipped what we expect is a tri-turbo oil-burner and an M badge on its rump. Follow the jump to watch the intentionally blurry video. We're guessing that the un-blurred real-life version will debut at the Geneva Motor Show in March.
