Quick model context before comparing photos and trim-level specifications.
Introduced in June 2021, the facelifted BMW X4 (G02) continues to serve as the more dynamically styled sibling to the traditional X3.

BMW X4 (G02) overview
Editorial context for design, cabin, performance, practicality, and buyer notes.
Design
The X4 distinguishes itself from the closely related X3 with a roofline that sits 45 mm lower, a unique mesh-patterned grille, and elongated, narrow taillights. The 2021 restyling sharpens the front fascia with slimmer matrix LED headlights included as standard, merged grille surrounds, and vertical trim elements on the outer edges of the bumper. The rear profile is updated with prominent, trapezoidal-style exhaust finishers. Buyers can also specify laser-phosphor headlight technology for enhanced nighttime visibility.
Interior
Inside, the updated X4 adopts the driver-focused cockpit architecture of the 4 Series. This includes a redesigned center console, updated climate switchgear, and a new steering wheel design. Standard equipment includes sport seats, three-zone automatic climate control, and a 10.25-inch Live Cockpit Plus infotainment system. Upgrading to the Live Cockpit Professional brings a larger 12.3-inch display running BMW Operating System 7, which supports over-the-air updates. Wireless Apple CarPlay and Android Auto allow projecting navigation directly onto the digital instrument cluster and optional head-up display.
Performance
The powertrain lineup relies heavily on the integration of a 48-volt mild-hybrid system, which adds an 11-horsepower boost during acceleration and recovers energy during braking. The gasoline range spans from the 184-hp xDrive20i to the 360-hp M40i, which utilizes a 3.0-liter turbocharged inline-six to reach 100 km/h in 4.9 seconds. Diesel options include the 190-hp xDrive20d, the 286-hp xDrive30d, and the high-output M40d delivering 340 hp and 700 Nm of torque. All configurations are mated to an eight-speed automatic transmission and xDrive all-wheel drive.
Practicality
Despite its sloping roofline, the X4 remains a functional compact crossover. The cabin seats five, and the trunk offers a useful 525 liters of cargo space. Measuring 4,751 mm in length with a 2,864 mm wheelbase, it provides adequate room for passengers while maintaining a manageable footprint for urban environments. The 204 mm of ground clearance ensures it can handle rougher roads or light snow without issue.
Safety and tech
The G02 X4 is available with a comprehensive suite of active safety systems, including the optional Driver Assistant Professional, which operates at speeds up to 210 km/h. Technology highlights include a 360-degree surround-view camera system, Amazon Alexa integration, and an optional 464-watt Harman Kardon audio system. Comfort upgrades such as ventilated front seats with memory functions, heated seating across both rows, and premium Merino leather upholstery are also available.
Buyer notes
When comparing trims, buyers should weigh the efficiency of the 2.0-liter four-cylinder models against the performance-oriented M40i or M40d inline-six variants. Since an eight-speed automatic and all-wheel drive are standard across the board, primary decisions will revolve around engine output and optional tech packages. Features like the M sport rear differential, variable ratio steering, and adaptive suspension are separate options tailored toward improving driving dynamics.
