2025 BMW 3-Series Adds More TorqueBMW
  • BMW revealed facts and figures for the lightly revised 3-series, including upgraded power figures.

  • The 2025 M340i adds four horsepower and 29 pound-feet of torque thanks to a revised 48-volt hybrid system—while the four-cylinder remains the same.

  • Pricing for the 2025 3-series starts at $46,675 for the entry 330i and ranges to $62,775 on the top-spec M340i xDrive.

Updates are pretty slim for the 2025 BMW 3-series—which is unsurprising, since it was last facelifted in 2023. BMW revealed the facts and figures for the benchmark sedan, including new output numbers for the turbocharged inline-six and new software for the infotainment system.

The biggest changes for the updated 3-series involve the M340i's turbocharged 3.0-liter inline-six, upgraded for "sharper power delivery and greater efficiency," according to BMW. The already robust powertrain squeezes out an additional four horsepower and 29 pound-feet of torque thanks to a revised version of the 48-volt hybrid system. Total output comes out to 386 horsepower and 398 pound-feet of torque.


The less powerful turbocharged 2.0-liter four-cylinder found in the 330i chugs along with unchanged output according to the manufacturer. Don't be fooled, though: the spunky four-pot still churns out a solid 255 horsepower and 295 pound-feet of torque.

BMW says it put the new 3-series through "rigorous development work" to improve chassis dynamics. Stiffer chassis mounts connecting the dampers to the body reportedly help to refine the ride quality, while the steering effort in Comfort mode is now lighter.

Inside, the new 3-series joins newer BMWs such as the electric i5 in using the brand's iDrive 8.5 interface, which accommodates over-the-air updates. The new system features customizable widgets, while the redesigned home screen continuously displays the navigation system.

Along with two new steering-wheel options, a pair of new paint colors—one red, one blue—and a new set of 19-inch M alloy wheels for the 330i round out the rest of the changes for 2025. Pricing starts at $46,675 for the entry-level 330i and ranges up to $62,775 for the top-spec M340i xDrive.
