BMW 4 Series Gran Coupe trim comparison
2026 BMW 4 Series Gran Coupe 430i xDrive vs M440i
The 4 Series Gran Coupe 430i xDrive starts at $53,200 while the M440i is $65,100. That $11,900 gap buys 7 meaningful differences.
This is a powertrain and drivetrain change. The M440i gets the 3.0L I6 mild-hybrid Turbo and RWD, so the $11,900 is buying a different driving experience, not just nicer trim.
This is a real hardware fork, not just a trim-label shuffle. The 430i xDrive is enough if the 2.0L I4 mild-hybrid Turbo with AWD already fits your routine; the M440i only earns the jump when the 3.0L I6 mild-hybrid Turbo and RWD setup is the point of the upgrade.
The cleanest way to feel this upgrade is through the payment: about $209/month more over 60 months, or roughly $12,540 extra all-in once interest is included. If that different powertrain is not part of your real use case, the cheaper trim keeps more money in your pocket without changing the core experience you need.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
