BMW 4 Series trim comparison
2025 BMW 4 Series M440i xDrive vs M4
The 4 Series M440i xDrive starts at $66,850 while the M4 is $79,700. That $12,850 gap buys 7 meaningful differences.
This is a powertrain and drivetrain change. The M4 gets the 3.0L I6 Turbo and RWD, so the $12,850 is buying a different driving experience, not just nicer trim.
Choose the M440i xDrive if the 3.0L I6 mild-hybrid Turbo with AWD already covers the way you drive. Move to the M4 only when the 3.0L I6 Turbo and RWD combo is the reason you are shopping higher, because that is the real hardware split here.
Think about this as a monthly tradeoff, not just a sticker gap. The M4 adds about $226/month on a typical 60-month loan, or around $13,560 more overall with interest. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
