BMW’s ever-expanding crossover lineup gains another new model in the 355-hp X4 M40i. In the same vein as the M235i coupe, the M40i’s confusing name means that it’s not a full M car, but boasts key performance enhancements to set it apart from the standard BMW X4 xDrive35i.
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.
Also helping the X4 M40i live up to its M badging are chassis tweaks including stiffer springs, adaptive dampers, stickier Michelin Pilot Super Sport tires, and more rear bias for the standard all-wheel-drive system. We’ll have to wait to drive the M40i to see if the unnecessarily heavy steering we noted in our drive of the X4 xDrive35i remains.
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.
