2017 BMW X4 M40i AWD

Model Highlights

The BMW X4 comes in two basic guises: X4 xDrive28i and X4 M40i. The xDrive28i is powered by a turbocharged 2.0L 4-cylinder engine that produces 240 horsepower, while the M40i utilizes a twin-turbocharged 3.0L 6-cylinder engine producing 355 horsepower. In both cases, power is sent to all four wheels via an 8-speed automatic transmission. The X4 further sets itself apart from the X3 with a unique interior featuring very nice materials and high quality construction throughout. The ride height is lower than in the X3 and it offers drivers a more classically coupe-like view throughout the greenhouse. Handling has been improved over the X3 as well, with the X4 doing a passable impersonation of a sports car on winding roads, thanks to a lower ride height and more aggressively tuned suspension. The X4 comes nicely equipped with both xDrive28i and M40i versions getting a nearly identical set of amenities. Standard equipment includes 18-inch wheels, 8-way power adjustable front seats, a walnut trimmed interior, a powered glass moonroof, a powered tailgate, rear parking sensors, rain sensing wipers, dynamic cruise control and a 9-speaker stereo with satellite radio. In the xDrive35i, a Harman/Kardon surround system is standard. There are two optional packages available on both xDrive28i and M40i models, dubbed 'M Sport' and 'xLine'. Both packages significantly change the exterior of the X4, with the M Sport line deleting various chrome bits and adding more aggressive, body colored exterior enhancements. The M Sport line also includes unique 19-inch wheels and a few interior styling tweaks. The xLine takes the standard X4 in the opposite direction, adding rugged looking exterior enhancements as well as its own set of 19-inch wheels. Safety is enhanced by a full complement of electronic aids as well as by several airbags. Other safety features include a hill start function as well as a mode for descending slippery slopes.
