2018 X4 New Car Test Drive
The BMW X4 Sports Activity Coupe is structurally similar to the compact X3, but it's topped by a seductively curved roof that almost sends it into another category.
The X4 has four doors, so it's not really a coupe. Taking the X3 that serves as its foundation, BMW developed a roofline that tapers toward the rear. More intriguing in appearance than its taller cousin, the X4 loses some interior space and functionality.
The X4 was launched as a 2015 model. For the 2017 model year, two versions of are available, the X4 xDrive 28i and the new X4 M40i.
2017 X4 xDrive 28i models now come standard with Wireless charging and a wi-fi hotspot with enhanced USB and Bluetooth. Navigation has been upgraded to iDrive 5.0 on 2017 BMW X4 models. A turbocharged 2.0-liter four-cylinder develops 240 horsepower and 260 pound-feet of torque. Surprisingly spirited, the X4 28i can reach 60 mph in six seconds.
The new BMW X4 M40i model supplants the former xDrive35i. Ranking as an authentically potent performance vehicle, the M40i holds a 3.0-liter turbocharged inline six-cylinder engine that generates 355 horsepower and 343 pound-feet. That one accelerates to 60 mph in a mere 4.7 seconds.
Both engines mate with a smooth-shifting 8-speed automatic transmission and xDrive all-wheel drive. Adhering to BMW tradition, each promises taut, confident handling talents, helped by an independent suspension similar to the one used in the X3. Electronic steering offers variable effort and an alterable ratio. Three driving modes are available: Eco, comfort, and sport.
Befitting its performance qualities, the X4 M40i gets a specially calibrated transmission and xDrive system, as well as quicker steering, 20-inch wheels, and sportier suspension tuning. In order to achieve suitable sounds of power, a resonator sends some engine noise right into the cabin.
Neither the National Highway Traffic Administration nor the Insurance Institute for Highway Safety has crash-tested the X4, though the X3 earned a five-star overall rating.
The 2017 BMW X4 xDrive 28i ($45,550) comes with the 2.0-liter engine, SensaTec simulated-leather upholstery, wood trim, a power liftgate, moonroof, Bluetooth and USB connections, automatic climate control, power front seats, 18-inch wheels, adaptive headlights, paddle shifters, variable sport steering, rear parking sensors, and a leather-wrapped steering wheel.

An xLine group includes 19-inch wheels and copper gloss trim.
M40i ($58,100) comes with the six-cylinder engine, plus a Harman Kardon surround-sound system, the M Sport package, Dynamic Damper Control, keyless access, aluminum interior trim, front/rear parking sensors, and 19-inch wheels.
