BMW 4 Series trim comparison
2025 BMW 4 Series 430i xDrive vs M4 Competition xDrive
The 4 Series 430i xDrive starts at $61,150 while the M4 Competition xDrive is $89,000. That $27,850 gap buys 4 meaningful differences.
This trim jump changes the engine from 2.0L I4 mild-hybrid Turbo to 3.0L I6 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 3.0L I6 Turbo every week, the M4 Competition xDrive makes sense. If not, the 430i xDrive is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
The cleanest way to feel this upgrade is through the payment: about $490/month more over 60 months, or roughly $29,400 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.
