Year over year

What changed

  • BMW's U.S. catalog continues the four-model 330i/M340i roster and does not list a 330e plug-in hybrid.
  • The three M3 drivetrains retain their distinct 473-, 503-, and 523-hp outputs and manual/automatic boundaries.
  • No M3 CS or other 2026 special edition appears in BMW's current U.S. model roster.

Worth knowing

Notable

  • The manual transmission remains exclusive to the 473-hp rear-drive M3.
  • The 523-hp tune and M xDrive remain exclusive to M3 Competition xDrive.

Living with it

Reliability & ownership notes

  • Use the exact 330i, M340i, manual M3, rear-drive Competition, or Competition xDrive identity when selecting powertrain and driveline parts.
  • BMW's Condition Based Service determines many routine service events; the separate 1,200-mile running-in service applies to M models.

Maintenance & service parts

Keep your 2026 3 Series on the road
