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.
