BMW has introduced the 2025 3 Series, and the biggest upgrade is to the powertrain — every model has at least a mild hybrid system.
The standard gas and diesel variants have a 48V hybrid assist that improves both efficiency and power delivery. You’ll see the greatest improvement with the performance-oriented M340i (pictured above), where the union of a 3L turbo six-cylinder engine with the electric motor provides 386HP (up slightly from 382HP) and a significantly larger 398ft/lb of torque (increased from 369).
Plug-in hybrid (PHEV) models also deliver a “considerably longer” electric range, BMW said. The 330e Sedan and 330e Touring wagon use a higher-voltage 19.5kWh battery to get between 50 miles to 63 miles of all-electric driving depending on the configuration. That could handle the daily commute and even some longer drives, according to the company.
The PHEV models combine a four-cylinder gas engine with the hybrid motor to output 292HP. They can also charge faster, reaching full capacity in two hours and 15 minutes when using three-phase AC charging.
The interior technology has also received an upgrade through new software. It’s now easier to access many controls directly from the home screen instead of digging through menus. Navigation is simpler and provides more information as you drive. You can sync account details just by scanning a QR code with your phone, and pay for parking or gas in parts of Europe directly from the car.
You get an eSIM for 5G data that’s tied to your BMW account, not the car, and extends your existing phone plan. You can migrate vehicles or travel abroad without losing your always-online access, provided you’re willing to shoulder any costs from your carrier.
Production for the US starts in August. The 330i starts the range at $46,675 including the destination charge, while the M340i costs $60,775. All-wheel drive (aka xDrive) costs an additional $2,000.
The ubiquitous hybrid engines are important for BMW and possibly the industry as a whole. The German badge can now say that its most popular sedan always includes some kind of electrified power plant. The 3 Series is also one of the most recognizable and bestselling luxury sedans worldwide. This potentially gets hybrids to more people and helps ease the transition toward EVs.
