As it enters its seventh model year, the 2025 BMW 3 Series sports sedan receives some updates. They are miniature, but they appear everywhere, from the body to the engine. So let’s get to it.
The biggest change is the introduction of 48-volt mild-hybrid assist in every powertrain. The M340i’s 3.0-liter turbocharged six-cylinder engine gets the biggest boost from this change, and quite literally so. When the recent electric motor is engaged, power increases to 386 horsepower and 398 pound-feet of torque, up from 382 and 369 respectively. Although 0-60 mph times remain unchanged. Similarly, the 2.0-liter turbocharged four-cylinder engine has the same power output as before, with 255 horsepower and 295 pound-feet of torque. Interestingly, it is now a Miller cycle engine. That way you’ll have it in your back pocket during car trivia night at the bar.
BMW also says it has made a number of changes to the chassis, but did not go into detail about those changes. Only stiffer rear shock mounts and lighter steering tuning in Comfort mode were highlighted.
Outside, BMW stuck with the usual model-year updates on recent wheels and color options. The interior has been slightly updated with a recent two-spoke steering wheel on the 330i and a three-spoke flat-bottom steering wheel on the M340i and 330i with the M Sport package. The dashboard receives a few minor tweaks, mainly thanks to recent ambient lighting around the center vents. The infotainment system has also been updated with a recent menu structure to make functions easier to access and avoid having to dig through so many submenus. We’ll evaluate it ourselves when we get our hands on the car.
Customers will be able to get their hands on the 3 Series later this year. Production of units intended for the American market begins in August in Mexico. Prices, including a $1,175 destination charge, are listed below. Adding all-wheel drive to either model costs an additional $2,000.
