Starting at $48,595 (including $995 destination fee), the BMW X4 xDrive 28i receives a notable $2,050 MSRP increase for 2018. Outfitted with 19-inch wheels and all-season run-flat tires, the 28i also features automatic wipers, adaptive Xenon headlights, LED fog lights, power-folding heated side mirrors with auto-dimming, and a power tailgate as standard.
Interior amenities include keyless ignition, a rearview camera, leatherette seats with 8-way power adjustments in front, 40/20/40-split seats in back, a multifunction Sport leather steering wheel, automatic climate control, a moonroof, an auto-dimming rearview mirror, ambient lighting, a nine-speaker stereo, BMW's iDrive infotainment system, and BMW ConnectedDrive telematics.
A start/stop system, adaptive cruise control, four-mode driving dynamics control, hill descent control, and park distance control are standard technology.
A Cold Weather Package ($950) adds retractable headlight washers and a heat setting for the steering wheel and all seating positions, which strikes us as a bargain. A Driving Assistance Package ($1,700) includes blind spot monitoring, a head-up display, a premium information instrument cluster, and active driving assistant. For an extra $1,200, a Driving Assistance Plus Package updates the active driving assistant and adds pre-collision mitigation. One caveat is that navigation ($1,700), which is available a la carte, must be paired with the Driving Assistance package.
The M Sport Package ($1,700) adds performance run-flat tires and an aerodynamic body kit, special exterior trim, sportier seats, brushed aluminum interior trim, and an M steering wheel. Wheels and tires can be upgraded to 20-inchers with performance rubber for $950. The Premium Package ($2,200) offers lumbar support, SiriusXM radio with a one-year subscription, leather upholstery, and enhanced keyless entry.
A Lighting Package ($1,900) adds LED adaptive headlights and automatic high beams. The Parking Assistance Package ($700) adds a surround-view camera system and parking assistant, which, when traveling at speeds less than 22 mph, will search for available parking spaces as well as steer the vehicle into position.
Separately, heated front seats ($500), wireless charging with Wi-Fi hotspot capability ($400), a premium Harman Kardon sound system ($875), Apple CarPlay-only compatibility ($300), dynamic damper control ($1,000), and blind spot monitoring ($500) can be added piecemeal.
