Land Rover Range Rover Sport trim comparison
2026 Land Rover Range Rover Sport P400 Dynamic SE vs P550e Autobiography
The Range Rover Sport P400 Dynamic SE starts at $90,800 while the P550e Autobiography is $118,700. That $27,900 gap buys 7 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 Dynamic SE 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 P550e Autobiography adds about $491/month on a typical 60-month loan, or around $29,460 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.
