2013 BMW X6

More exciting, of course, is that BMW now will offer M Performance packages for both the turbocharged 3.0-liter six and the twin-turbo 4.4-liter V-8. Additional power comes as a result of cranking up the turbo boost; on the six, output rises from 300 hp and 300 lb-ft of torque to 315 hp and 330 lb-ft. (These are just a shade lower than the 320 hp and 332 lb-ft delivered by the performance edition package in the outgoing 335i, which featured the same engine; the difference is attributable to different intake and exhaust plumbing in the two vehicles.) The M Performance upgrade will increase output in the V-8–toting X6 xDrive50i by 40 hp and 30 lb-ft, for totals of 440 and 480. The package also includes aesthetic touches like 20-inch wheels, black chrome exhaust tips, and dark window trim.
