To that end, BMW fitted the performance-oriented SUV with a high-output version of the turbocharged 3.0-liter six-cylinder from the non-M-tuned X4. Thanks to tweaks like different spark plugs, more turbo boost, and a high-performance exhaust, the M40i produces 55 extra horsepower and 43 more lb-ft of torque, for totals of 355 hp and 343 lb-ft. Along with different tuning for the eight-speed automatic, BMW says the M40i’s powertrain upgrades lower the X4’s 0-60 mph time by half a second, down to 4.7 seconds.
Visually, it’s hard to tell the 2016 BMW X4 M40i apart from its non-M sibling. Grey trim adorns the mirrors and the grille, while the front and rear fascias boast a few additional vents and aerodynamic elements. The M40i also wears 20-inch wheels and plenty of M badges, as expected. On the inside, there’s an M-specific steering wheel with paddle shifters, and the M40i comes standard with sport seats and leather upholstery.
BMW hasn’t yet announced pricing for the M40i, but it should warrant a premium of a few thousand dollars over the standard 2016 BMW X4 xDrive35i model’s starting price of $50,245. Keep an eye out for more information as we get closer to the M40i’s arrival at U.S. dealerships in February of next year.
