BMW launched its X4 crossover model in 2014, and gives it the M performance treatment for the Detroit auto show.
A more aggressive fascia gives it that M look.
Benefiting from BMW's innovative technology, the X4 M40i can be had with LED headlights.
Under the hood, the X4 M40i's turbocharged 3-liter inline six-cylinder engine makes 355 horsepower and 343 pound-feet of torque.
The 19-inch wheels are staggered, with Michelin Pilot Super Sport tires front and rear, with the rears featuring 30 millimeters more width.
As further handling help, the X4 M40i gets its all-wheel-drive system tuned for a rear bias.
The rear hatch offers easy access to cargo space, but the fastback rear limits capacity.
The dashboard features M cues here and there.
An eight-speed automatic transmission receives a sport mode that holds the revs high, for enhanced throttle response.
The lack of M buttons on the steering wheel suggests the X4 M40i isn't as hard-core as its performance siblings.
