The 2025 model year

Overview

For 2025 BMW narrowed the U.S. regular 3 Series roster to the 330i and M340i, each offered with rear- or all-wheel drive; the 330e plug-in hybrid was no longer listed. Both engines gained revised 48-volt mild-hybrid systems. The three-model M3 range continued, with the Competition xDrive receiving a 20-hp increase to 523 hp.

Living with it

Reliability & ownership notes

  • The 2025 B48 and B58 mild-hybrid revisions change powertrain applicability from earlier G20 years; order by VIN and exact model year.
  • The 523-hp calibration belongs only to M3 Competition xDrive, not the manual M3 or rear-drive Competition.
