BMW X4 Generations: F26 and G02

The BMW X4 has evolved through two main generations, each refining the coupe-SUV formula and introducing new technologies, engines, and safety systems.

F26 (2014–2018)

The first-generation X4, code F26, debuted in 2014 on the CLAR platform, essentially a coupe variant of the X3 F25. Its exterior design emphasized sporty proportions, with a lowered roofline, aggressive front fascia, and sloping rear.

Engines:

• Gasoline: N20 2.0 L, N52 3.0 L, N55 3.0 L

• Diesel: N47 2.0 L

Common Issues:

• Turbocharger failures in N20/N55 engines

• Timing chain wear

• DPF (diesel particulate filter) clogging

• Electrical and iDrive malfunctions

While the F26 brought style and excitement, early models require careful inspection, particularly for engine and electronics issues.

G02 (2018–2024+)

The second-generation X4 (G02) features a modern design with sharper lines, improved cabin ergonomics, and updated infotainment systems. Engine options expanded with the introduction of BMW’s B-series engines and the iX4 fully electric version.

Engines:

• Gasoline: B48 2.0 L, B58 3.0 L

• Diesel: B47/B57 2.0–3.0 L

• Electric: iX4

Variants: M40i and M Performance models deliver high power output but require more attentive maintenance.

Takeaway: Regardless of generation, the BMW X4 requires careful attention to service history, maintenance, and technical condition. This is where a BMW X4 VIN check proves invaluable.
