The 2023 model year

Overview

The 2023 U.S. 3 Series received a substantial mid-cycle update with revised exterior details, BMW Curved Display, and iDrive 8. The 330i, 330e, and M340i each remained available with rear- or all-wheel drive, while the three regular M3 configurations continued and BMW added the North America-exclusive M3 Edition 50 Jahre BMW M.

Year over year

What changed

  • Mid-cycle exterior revisions arrived with the standard BMW Curved Display and iDrive 8.
  • The M340i and M340i xDrive used BMW's 48-volt mild-hybrid inline-six system.
  • The limited M3 Edition 50 Jahre BMW M joined as a North America-exclusive model based on the M3 Competition xDrive.

Worth knowing

Notable

  • First model year for the G20 3 Series mid-cycle design and cockpit update.
  • The M3 Edition 50 Jahre celebrated 50 years of BMW M with five heritage-inspired paint colors.

Living with it

Reliability & ownership notes

  • The 330e high-voltage plug-in hybrid, M340i 48-volt mild hybrid, and M3 S58 require configuration-specific service parts and procedures.
  • Curved Display/iDrive 8 equipment distinguishes the 2023 update; verify software campaigns and service history on used cars.
