The redesigned 3 Series sedan brings new infotainment tech, standard advanced safety features, improved handling, and better fuel economy. The 330i is fitted with a punchy 2.0-liter, turbo four-cylinder engine paired with a smooth and responsive eight-speed automatic transmission. All-wheel drive is available. Handling is nimble, but the ride is firm. Seat comfort and fit and finish are first rate. The iDrive infotainment system is logical to use once mastered. Forward collision warning and city-speed automatic emergency braking with pedestrian and cyclist detection are standard. All-speed AEB, BSW, ACC, and LCA are optional. The M340i, powered by a 3.0-liter turbo six-cylinder, and the 330e plug-in hybrid arrived in 2020. The infotainment system was updated in 2023 with a larger, curved display and touchscreen-based climate controls. 2024 was the last year for the plug-in hybrid version. A 2025 refresh brought styling changes, further infotainment updates, and revised suspension tuning.
