BMW has confirmed that it will debut an all-new X6 M performance variant of its "sports activity coupe" at the 2009 New York Auto Show next month. A 2009 BMW X6 xDrive 35i is pictured above.

Rumors about a high-performance "M" version of the X6 and X5 have been circulating since last summer and were confirmed in January. The X6 M is expected to wear minor cosmetic changes along with the M division's signature quad tailpipes, and it's expected to ride a bit lower. Under the hood we expect to find a twin-turbocharged version of BMW's 4.4L V-8, likely good for over 500 hp. It's expected to put power down through BMW's xDrive all wheel-drive system, which will be tuned for a rear-bias.

BMW promises that the X6 M will feature a variety of new engine, drivetrain and suspension, likely needed to keep this beast composed with its high power levels. We'll find out all the exact specifications when the car bows in New York.
