BMW just launched a microsite on the internet announcing that the high-performance M versions of the X5 and X6 will make their debut 30 days from now. Considering the New York Auto Show starts on April 19, that means both models will be revealed ahead of the show.

As revealed in the teaser video, the sport activity vehicles will be powered by a twin scroll turbocharged V8 engine, which just backs up our suspicions of the 500+ hp 4.4-liter twin turbo powerplant making an appearance in these SAVs.
