BMW 4 Series trim comparison
2024 BMW 4 Series M440i xDrive vs M4
The 4 Series M440i xDrive starts at $71,550 while the M4 is $78,100. That $6,550 gap buys 7 meaningful differences.
This is a powertrain and drivetrain change. The M4 gets the 3.0L I6 Turbo and RWD, so the $6,550 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.
The cleanest way to feel this upgrade is through the payment: about $115/month more over 60 months, or roughly $6,900 extra all-in once interest is included. 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.
