G01 · X3

What the BMW G01 Is

The BMW G01 is the chassis code for the third-generation X3, built from 2018 through 2024. Riding on BMW's flexible CLAR (Cluster Architecture) platform shared with the 3 Series and 5 Series, the G01 traded the outgoing F25's older bones for a lighter, stiffer structure. The result was sharper steering, better body control, and a noticeable step up in cabin quality — enough to keep the X3 among the most driver-focused compact luxury SUVs of its era.

Models & Drivetrains Offered

In the US market, the G01 X3 was sold in six configurations spanning rear-drive, all-wheel-drive, plug-in hybrid, and performance-oriented trims:

• X3 sDrive30i and X3 sDrive30i SA — rear-wheel-drive four-cylinder base cars.
• X3 xDrive30i and X3 xDrive30i SA — the volume all-wheel-drive versions.
• X3 xDrive30e — the plug-in hybrid, pairing a turbo four with an electric motor for short all-electric commutes.
• X3 M40i — the performance flagship, powered by BMW's turbocharged inline-six.

The 30i trims use BMW's turbocharged 2.0-liter four-cylinder, while the M40i steps up to the smooth, torque-rich B58 inline-six for genuinely quick straight-line pace. All G01 models pair with the excellent ZF eight-speed automatic. To see how these engines trace through BMW's broader lineup, explore the family tree on our BMW DNA page and compare the six-cylinder heritage in the B58 reference.

What It's Like to Own & Buy

The G01 makes a strong used-buy case: it drives like a smaller car, the interior holds up well, and iDrive 6/7 infotainment feels modern years later. The four-cylinder cars deliver respectable efficiency and lower running costs, while the M40i offers real enthusiast appeal without the maintenance burden of a full M car.

As with any modern turbo BMW, prioritize a clean service history — regular oil changes, cooling-system attention, and up-to-date software. The xDrive30e plug-in hybrid adds battery and charging hardware to inspect, so verify electric range and check for any high-voltage service records. Enthusiasts cross-shopping BMW's larger sport heritage often look back at chassis like the E60 5 Series and E63 coupe to appreciate how far the brand's dynamics evolved into the G01 era.

Strengths and Things to Watch

Standout strengths include balanced handling, a premium cabin, a broad engine range, and strong drivetrain durability from the ZF automatic. Buyers should still budget for routine BMW upkeep — cooling components, gaskets, and electronics deserve inspection on higher-mileage examples — and confirm the exact trim and options against the VIN before purchase.
