2025 BMW 3 Series Gets More Power And Modest Styling Updates

For almost 50 years now, the BMW 3 Series has resided at the core of the BMW brand. So even though the 3 Series was facelifted just a few years ago, BMW engineers aren’t resting on their laurels, delivering a few modest upgrades for the 2025 model year which make the Ultimate Driving Machine that much better.

The biggest changes for the 2025 3 Series involve the M340i’s turbocharged 3.0-liter inline-six, which has been upgraded for “sharper power delivery and greater efficiency,” thanks to a new 48V mild hybrid (MHEV) system. The auxilliary electric drive of the 48V starter generator can provide 11 hp of boost to the TwinPower Turbo engine, resulting in a maximum system output of 386 hp @ 5,200-6,250 rpm and 398 lb-ft of torque @ 1,900-4,800 rpm.

The engine is paired with an 8-speed Steptronic Sport transmission to propel the BMW M340i from 0-60 mph in a scant 4.4 seconds (4.1 seconds with xDrive all-wheel drive). The engine’s surge of power is accompanied by an exhilarating soundtrack from the M Sport exhaust. Top speed is electronically limited to 155 mph.

While the less powerful turbocharged 2.0-liter four-cylinder found in the 330i makes the same 255 horsepower and 295 lb-ft of torque as the outgoing model, it still pulls hard, delivering a very engaging experience despite what the numbers might lead you to believe.

BMW says the chassis of the new 3-series benefits from rigorous development work. The blend of sporting flair and ride comfort for which the 3 Series is renowned has been further refined across all models with a series of targeted updates. Stiffer chassis mounts connecting the rear dampers to the body reportedly help to refine the ride quality, while the steering effort has been reduced in Comfort mode to achieve greater steering ease in everyday driving.

Inside, you’ll notice an upgraded infotainment system running BMW Operating System 8.5, which features a new home screen and QuickSelect rapid-access tech, bringing an improved menu structure. There’s also a customizable widget bar, simplified climate controls, improved navigation (continuously displayed on the screen), and an Augmented View function.

Drivers get one of two new steering wheel designs. BMW 330i models come standard with a new two-spoke wheel with a polygonal rim. M340i models and 330i models equipped with the M Sport package feature a new three-spoke flat-bottomed M steering wheel with a subtle stripe at top dead center – black on 330i M Sport models, red on M340i models.

The spectrum of exterior colors for 2025 includes two new colors: Arctic Race Blue metallic and Vegas Red metallic. To take personalization even further, customers may choose from two new BMW Individual shades: Frozen Pure Grey metallic and Frozen Portimao Blue metallic.

Vehicles with the M Sport package (optional on 330i models, standard on M340i models) will be fitted with new 19-inch M alloy wheels in double-spoke design (Style 995M) in either a bi-color or Jet Black finish. Alternatively, new BMW Individual 19-inch alloy wheels in Y-spoke design (Style 1038i) with a bi-color finish are optionally available across all models.

Pricing for the 2025 BMW 330i will start at $46,675, which is $1,180 more than the current model. The 2025 BMW 330i xDrive will start at $48,675. The six-cylinder-powered M340i, meanwhile, will start at $60,775, with the top-spec M340i xDrive starting at $62,775.
