The X6 XDrive 50i already has an M-division feel about it, with a 400 horsepower turbo V8 wallop and accompanying raucous exhaust note. Our imaginations reel with the thought of the M5's spectacular V10 finding its way into the X6's engine bay, but that's probably not going to happen. Most likely is a boost tweak for more power, revised suspension tuning, and more aggressive – yet still understated – bodywork. When it's a BMW wearing M badges, it's safe to assume power delivery akin to a solid rocket booster, backed up by handling that will make the X6's avoirdupois dance more gracefully than it already does. Maybe they will find a way to fix the V8's flinty ride while they're at it.
