G20 · 3 Series

What the BMW G20 Is

The BMW G20 is the seventh generation of the iconic 3 Series sports sedan, launched for the 2019 model year and running through 2026. Built on BMW's CLAR (Cluster Architecture) platform, the G20 is stiffer, lighter, and more refined than the F30 it replaced, while retaining the rear-biased balance that made the 3 Series a benchmark. A mid-cycle LCI update brought BMW's curved display and iDrive 8 to the lineup, keeping the car competitive against the latest rivals. If you want to understand where the G20 sits in BMW's lineage, our BMW DNA guide traces the model's evolution.

Models & Body Styles

The G20 generation in the US market is a sedan-only affair, offered in 12 configurations spanning gasoline, plug-in hybrid, and performance trims:

• 330i Sedan — the volume model, rear-wheel drive with the 330i xDrive all-wheel-drive counterpart.
• 330e Sedan — the plug-in hybrid, available in RWD and xDrive, pairing electric range with turbocharged efficiency.
• M340i Sedan — the performance flagship of the standard range, in RWD and xDrive form.

Both "NA" and standard designations appear in BMW's build data across these trims. To confirm exactly which variant, engine, and options a specific car carries, run the numbers through our BMW VIN decoder.

Engines & Drivetrains

The G20 leans on BMW's modular turbocharged family. The 330i uses the B48 2.0-liter turbo four, while the M340i steps up to the potent B58 3.0-liter turbo inline-six—one of BMW's finest modern engines, prized for its smoothness and strong tuning headroom. The 330e combines the B48 with an electric motor for meaningful electric-only commuting. Nearly all G20 models are offered with rear-wheel drive or BMW's xDrive all-wheel-drive system, paired with the ZF 8-speed automatic that has become a hallmark of modern BMWs.

Owning & Buying a G20

The G20 is a compelling used and CPO buy: refined, quick, and packed with technology. Enthusiasts consistently praise the B58-powered M340i for delivering near-M3 performance at a lower price. When shopping, prioritize documented maintenance—regular oil changes matter on these turbocharged engines—and verify software updates on iDrive-equipped cars. Plug-in 330e buyers should assess battery health and charging habits.

Notable Strengths

• Excellent chassis balance and steering feel
• The exceptional B58 six in M340i trim
• Strong tech and comfort after the LCI update

Compared to earlier sport sedans like the E90 generation or BMW's larger cars such as the E60 5 Series, the G20 feels distinctly more digital while keeping the driver engaged—a worthy continuation of the 3 Series legacy.
