BMW 4 Series trim comparison
2024 BMW 4 Series 430i xDrive vs M440i xDrive
The 4 Series 430i xDrive starts at $60,100 while the M440i xDrive is $71,550. That $11,450 gap buys 7 meaningful differences.
This trim jump changes the engine from 2.0L I4 Turbo to 3.0L I6 mild-hybrid Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 3.0L I6 mild-hybrid Turbo every week, the M440i 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.
Think about this as a monthly tradeoff, not just a sticker gap. The M440i xDrive adds about $202/month on a typical 60-month loan, or around $12,120 more overall with interest. 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.
