BMW 3 Series trim comparison
2024 BMW 3 Series 330e xDrive vs M340i xDrive
The 3 Series 330e xDrive starts at $47,600 while the M340i xDrive is $59,600. That $12,000 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.0L I4 phev 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 M340i xDrive makes sense. If not, the 330e xDrive is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
If you are budgeting this move monthly, the jump from the 330e xDrive to the M340i xDrive is about $212/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $12,720 more by the time interest is counted. 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.
