What the BMW G02 Is

The BMW G02 designates the second-generation X4, the coupe-profiled counterpart to the G01 X3. Produced from 2019 through 2025, the G02 rides on BMW's CLAR (Cluster Architecture) platform, sharing much of its structure with the G01 X3 while adopting a lower, fastback roofline and a more aggressive stance. Compared to the outgoing F26, the G02 grew slightly in wheelbase and track, sharpened its handling, and refined its cabin with BMW's iDrive and digital instrumentation.

Models & Body Styles in This Generation

In the United States, the G02 X4 was offered in two trims, both exclusively as the five-door SAC (Sports Activity Coupe) body:

• X4 xDrive30i — the volume model, powered by a turbocharged four-cylinder with standard all-wheel drive.
• X4 M40i — the M Performance flagship, built around a turbocharged inline-six for a substantial jump in power and dynamics.

Both models came standard with xDrive all-wheel drive, an eight-speed ZF automatic, and BMW's signature near-50/50 weight balance that defines the brand's driving DNA.

Engines & Drivetrains Offered

The xDrive30i uses BMW's B48 2.0-liter turbocharged four, a smooth and efficient unit shared across much of the modern lineup. The X4 M40i steps up to the B58 3.0-liter turbocharged inline-six, one of BMW's most celebrated modern engines—torque-rich, tunable, and remarkably durable. Both pair with the eight-speed automatic and permanent all-wheel drive, delivering confident year-round traction and quick, seamless shifts.

What It's Like to Own & Buy

The G02 X4 offers everyday usability with genuine driving engagement, particularly in M40i form. The B58-powered cars are prized for their strong performance and long-term reliability, while the B48 xDrive30i is the more economical choice for buyers prioritizing running costs. As with any modern BMW, prioritize a documented service history, verify software and oil-service records, and inspect for curb-rashed wheels and worn run-flat tires. Buyers cross-shopping older BMW performance eras may also look at classic chassis like the E60 5 Series or the E63 6 Series for a different flavor of the brand.

Strengths & Considerations

• Strengths: potent and reliable B58 inline-six, sharp handling, standard xDrive, premium interior.
• Considerations: the coupe roofline trims rear headroom and cargo space versus the X3; run-flat tires firm up the ride.
