The 2024 BMW 330e is a plug-in hybrid variant of the popular 3 Series sedan, blending electric power with a traditional gasoline engine for enhanced fuel efficiency and performance. The 330e features a 2.0-liter turbocharged four-cylinder engine paired with an electric motor, delivering a combined output of 288 horsepower and 310 lb-ft of torque. Other engine options for the 2024 3 Series include a 2.0-liter turbocharged four-cylinder (330i), a 3.0-liter turbocharged inline-six (M340i), and high-performance variants of the M3. All engines are paired with an 8-speed automatic transmission. Owners often praise the 330e for its responsive acceleration, comfortable ride, and luxurious interior. Some common dislikes include the relatively small trunk space due to the hybrid battery pack, and the complexity of the infotainment system.
