BMW X5 trim comparison
2026 BMW X5 xDrive40i vs xDrive50e
The X5 xDrive40i starts at $70,600 while the xDrive50e is $76,000. That $5,400 gap buys 7 meaningful differences.
This trim jump changes the engine from 3.0L I6 mild-hybrid Turbo to 3.0L I6 phev Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 3.0L I6 phev Turbo every week, the xDrive50e makes sense. If not, the xDrive40i 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 xDrive40i to the xDrive50e is about $95/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $5,700 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.
