2013 BMW X6 M live at New York Auto Show reveal

BMW has treated its high-performance X6 M to a refresh for the 2013 model year, rolling the controversial bad boy out during the New York Auto Show for its first official appearance. Unfortunately, the changes are so subtle that we required an official BMW tour guide to point them out. In lieu of such a service for each of our readers, the next paragraph will have to suffice.

Most obvious is the new 'power bulge' hood, borrowed from the now-defunct BMW X6 Active Hybrid. Less visible are the cosmetic changes to the BMW-signature kidney grill and the new optional LED headlights (active HID bulbs remain standard). Peer inside the 20-inch wheels to spot the painted calipers, now in a distinguished "M" blue (vehicles with optional carbon/ceramic brakes have gold calipers). Lastly, inside the cabin, BMW's active sport seats are now standard.

Unchanged – and rightly so – is the gobsmacking twin-turbocharged 4.4-liter V8 boasting 555 hp and 501 pound-feet of torque. Mated to a six-speed paddleshift automatic and permanent all-wheel drive, the hunchbacked hero will easily crack 60 mph in under than five seconds. By the way, you'll have to make your own arrangements to get the gaudy Olympic sponsorship graphics seen on the vehicle above.
