Introduced in 2015, the BMW X4 is a compact crossover vehicle based on the X3 but whose sleek design takes its cue from the larger X6. A second-generation X4 arrived in 2019, and moves into 2021 with no major changes compared to last year.
BMW X4 trims are based around the model’s engine choices. In xDrive30i, power is from a 2.0L turbo four-cylinder, and M40i models get a 3.0L turbocharged six-cylinder. Both engines come with an eight-speed transmission and all-wheel drive.
BMW also makes a performance-focused X4 M that’s covered in a separate buyer’s guide entry.
The BMW X4’s standard features include a heated steering wheel, 20-inch wheels and run-flat tires, tire pressure monitoring, an alarm system, a panoramic sunroof, leather upholstery, auto-dimming side and rearview mirrors, heated front sport seats with power adjustments, automatic climate control, LED fog lights, satellite radio, Apple CarPlay connectivity, and an M sport suspension.
M40i adds 21-inch wheels, active LED headlights, adaptive M suspension, connected package professional, leatherette dashboard trim, automatic high beams, an M aerodynamics package, an M leather steering wheel, and M sport brakes.
A driver assistance package adds a highway driving assist system with active cruise control, lane control assist, and lane change warning.
An M Sport package brings a sport suspension, dynamic damper control, an aerodynamics package, M leather steering wheel, and high-gloss exterior trim.
Premium package essential gains passive keyless entry, ambient lighting, wireless smartphone charging, head-up display, and an integrated garage door remote; an enhanced version of this pack adds automatic high beams, galvanic controls, heated rear seats, full-LED adaptive headlights, and a Harman/Kardon stereo.
As of this writing, BMW hadn’t published fuel consumption estimates for the 2021 X4, but its figures should be similar to those for the 2020 model, which are 10.0/8.2 L/100 km (city/highway) for the xDrive30i, and 11.3/8.7 for the M40i model.
The BMW X4’s main competition comes from the Mercedes-Benz GLC Coupe. You could also cross-shop it against almost any vehicle in the vast compact luxury crossover class, where you’ll find models from just about every premium automaker.
