BMW has officially unveiled the second-gen X5 M50d performance diesel SUV having previewed the model while revealing the X5 M Sport back in May. Based on the latest 2014 X5, the sporty oil-burning SUV is a product of BMW's M Performance line motivated by the world's most powerful straight-six diesel unit. The 3.0-liter triple-turbocharged six-cylinder engine is rated at 381 hp and 546 lb-ft of torque, which is sent to all four wheels via an eight-speed automatic box and xDrive AWD system.

0-62 mph is quoted at 5.3 secs, top speed is limited to 155 mph and economy is an impressive 35 mpg. Upgrades befitting an M Performance model include 19-inch M light alloys, a modest aero kit, Adaptive M suspension, while inside we find a sports steering wheel, M badging and metal scuff plates. The BMW X5 M50d will hit European showrooms in November, which is when the 2014 X5 lineup will be rolled out in the US. In the meantime, buyers can contact BMW about its individual program and new accessories for the latest X5. These include unique metallic shades, new wheels, custom interiors, transport bags, all-weather floor mats, and thermally-insulated cup-holders.
