Land Rover Range Rover trim comparison
2024 Land Rover Range Rover P400 SE vs P550e Autobiography
The Range Rover P400 SE starts at $107,400 while the P550e Autobiography is $141,100. That $33,700 gap buys 6 meaningful differences.
This trim jump changes the engine from 3.0L I6 mild-hybrid to 3.0L I6 phev. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 3.0L I6 phev every week, the P550e Autobiography makes sense. If not, the P400 SE 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 $594/month more over 60 months, or roughly $35,640 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.
