BMW X4 Expert Review
New for 2017
With the X4 xDrive35i engine-upgrade model no longer available, leaving the new-for-2016 BMW X4 M40i as the sole six-cylinder model in the lineup. The M Sport package for the X4 xDrive28i gets a redesigned M leather steering wheel. New options include the latest iDrive 5.0 navigation system, wireless charging, and Wi-Fi hotspot capabilities. Other changes include revised exterior paint and interior color options.
Two engine options are available for the BMW X4, starting with the xDrive28i model's turbocharged 2.0-liter I-4 that's rated 240 hp and 258 lb-ft. Go for the X4 M40i and the coupe-like CUV will be powered by a turbocharged 3.0-liter I-6 rated 355 hp and 343 lb-ft in. Both engines are backed by an eight-speed automatic transmission that routes power through a permanent all-wheel-drive system. The 2.0-liter engine has 2016 EPA ratings of 20/28 mpg city/highway (the 2017 model hasn't yet been rated), while the 3.0-liter engine is rated for 2017 at 19/26 mpg.
When the X4 arrived in 2015 it was available as the xDrive28i and 300-hp xDrive35i. Those two models were joined by the 335 hp M40i in 2016. The xDrive35i is no longer available for the 2017 model year. The X4 xDrive28i is available with the xLine package adds more luxurious touches, while the M Sport package adds a more sporty look. X4 M40i models come standard with the M Sport bits.
BMW's available Active Driving Assistant + Active Cruise Control with Stop & Go includes Pedestrian and Collision Warning with City Braking function, and a Lane Departure Warning. Other available safety tech includes Active Blind Spot Detection and rearview camera with Surround View. The optional Parking Assistant not only alerts the driver to a properly sized parallel parking space, but also steers the vehicle into said?parking spot. The BMW X4 hasn't been evaluated by the NHTSA or IIHS, but the X3 on which it's based received five stars (out of a possible five stars) in an overall NHTSA safety rating.
What We Think
"The tortured logic behind the X4 probably goes something like this," we wrote in an X4 review, "If you think a 3 Series wagon is too carlike, an X3 too much like a boring SUV, a 3 Series Gran Turismo practical but not sporty enough, a 4 Series Gran Coupe sporty but not practical enough, and you definitely don't want to drive a 3 Series sedan like everyone else, then the X4 is the perfect vehicle for you."
In a four-way comparison test of performance luxury crossovers the X4 xDrive35i finished last behind the Audi SQ4, Porsche Macan Turbo, and Mercedes-Benz GLA45 AMG. We concluded that "The BMW X4 is neither a convincing coupe nor a true performance SUV." The now discontinued 300-hp xDrive35i model reached 60 mph in 5.2 seconds in our testing. With BMW's claim that the new M40i model can reach 60 mph in 4.7 seconds, the more powerful 355-hp model could have a better chance in a rematch.
The coupe-like BMW X4 crossover loses less passenger and cargo volume than the X3 it's on which it's based compared to the transition from X5 to the coupe-like X6.
