What’s new
Mid way through last year the xDrive35i model was replaced by the more performance-oriented M40i model. For all 2017 models, wireless phone charging and a Wi-Fi hotspot are added to the options list, while the upgraded iDrive interface included with navigation has been updated. Finally, the steering wheel included in the optional M Sport package has a new design.
Vehicle overview
There are reasons people buy SUVs besides cargo capacity, extra ground clearance and access to all-wheel drive. Maybe you like sitting up high. Maybe you think they're cooler than a car. Maybe you've just driven them for years and it's what you prefer. Whatever the reason, the 2017 BMW X4 is one of the choices for those who aren't necessarily looking for a traditional SUV.

Avg. Midsize SUV
The X4 shares most of its componentry with the BMW X3. The cabin design and controls, its base engine, available features and the majority of mechanical bits and pieces are the same. Its most obvious area of difference is the X4's roofline, which slants down in such a way that BMW calls the X4 a coupe. This reduces comfort in the back, as the seat bottom is lower to open up more headroom. Cargo capacity is also compromised by the lower roof, so best to think of it as a trunk, really.
There is another key difference between the X4 and the X3. It's called the M40i. Unique to the X4, this high-performance model builds on the outgoing xDrive35i model. With a whopping 360 horsepower and numerous handling enhancements, it ups the ante in this segment just as compelling new performance entries like the Jaguar F-Pace, Mercedes-Benz GLC43 AMG Coupe and Porsche Macan GTS arrive on the scene for 2017.
In the end, though, it's hard for us to divorce the U from SUV, even if BMW's marketers refer to the X4 as an SAC, or Sport Activity Coupe. Whatever, if it walks like a duck and talks like a duck, who cares if its tail is a little different? As such, we think those well-rounded new competitors are ultimately less compromised. So too are more conventional compact luxury SUVs like BMW's own X3. So although not everyone buys an SUV for the same reasons, the X4's appeal may still be a bit limited.
Every 2017 X4 includes standard antilock disc brakes, traction and stability control, rear parking sensors, active head restraints, front-seat side airbags and full-length side curtain airbags. Also standard is BMW Assist eCall, which includes automatic collision notification and an emergency assistance button.
The Driver Assistance package adds front parking sensors and a rearview camera. The Driver Assistance Plus package adds those items plus active blind-spot monitoring, a surround-view camera system, lane departure warning, forward collision mitigation system with automatic braking and (available at extra cost) adaptive cruise control.
Optional safety equipment includes front parking sensors, a rearview camera, a surround-view camera system, active blind-spot monitoring, lane departure warning and a forward collision mitigation system with automatic braking.
During Edmunds testing, an X4 xDrive 28i came to a stop from 60 mph in 122 feet, an average performance among similarly sized luxury crossovers.
Edmunds' Expert Rating
You might already know that sitting up high and having a commanding view of the road can be a great thing. So if you're looking for a luxury SUV that gives you that sense of security along with a sleek design and strong performance, the uniquely styled 2016 BMW X4 is an interesting alternative.
Driving
There are no complaints when it comes to performance. The "base" turbo four-cylinder packs a real wallop when you put your foot in it, pressing you back in your seat and making a mockery of its claimed 240-hp output. Really, this is more than enough power for most shoppers. Only those desiring overkill should consider the M40i, which is a legitimate high-performance proposition with acceleration numbers that rival high-powered sport SUVs.
Similar accollades can be heaped upon the M40i's prowess around corners, as its steering and road-holding abilities should stand up well to not only the Porsche Macan but also other competitors from Jaguar and Mercedes. The same can't quite be said of the xDrive28i, though, which we've found to be a bit squishy and ponderous for a vehicle bearing the BMW badge. It's more comfort-oriented, which may nevertheless be welcomed by some shoppers.
Interior
The X4's front compartment feels somewhat more intimate than that of the X3, highlighted by a wide center console that creates a sporty, dual-cockpit feel. Top-quality materials are evident throughout and the various tech controls and features are typical for the segment (which means they'll probably be user- friendly enough after a lengthy get-to-know-you process).
The standard front seats provide adequate comfort, but definitely check out the M Sport front seats as their bolsters are much more substantial all around. The back seat may be an issue, though. It's well-shaped for two, but the bottom cushion has been mounted quite low to accommodate the downward sloping roofline. This reduces comfort considerably and headroom for taller passengers can still be tight. The back seats of more conventionally roofed rivals, including the X3, are much better. Even the similarly shaped Mercedes-Benz GLC-Class Coupe has a more spacious and comfortable back seat.
Things don't improve further back. With 17.7 cubic feet of storage behind the rear seat and 49.4 cubic feet with the rear seatbacks folded down, this crossover has less cargo room than the humble Volkswagen Golf hatchback. Now, there's no doubt that many will be fine with diminished practicality if they value the M4's distinctive styling, but just know that virtually every compact luxury SUV is more capable of carrying a big TV box or whatever other bulky items that would normally fit in an SUV. For comparison sake, the X3 maximum measurements are 27.6 cubes and 63.3 cubes, respectively.
2017 BMW X4 models
The 2017 BMW X4 is a four-door, five-passenger compact luxury SUV with a coupelike roofline. There are two trim levels, which correspond with engine choice: xDrive28i and M40i. Both come standard with all-wheel drive and a sport-tuned eight-speed automatic transmission that are optional on the otherwise mechanically related X3.
