Land Rover Defender trim comparison
2026 Land Rover Defender 110 P400 X-Dynamic SE vs 110 P500 X-Dynamic SE
The Defender 110 P400 X-Dynamic SE starts at $75,200 while the 110 P500 X-Dynamic SE is $99,100. That $23,900 gap buys 5 meaningful differences.
This trim jump changes the engine from 3.0L I6 mild-hybrid to 5.0L V8. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 5.0L V8 every week, the 110 P500 X-Dynamic SE makes sense. If not, the 110 P400 X-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 110 P500 X-Dynamic SE adds about $421/month on a typical 60-month loan, or around $25,260 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.
