Lexus NX trim comparison
2024 Lexus NX 350h Premium vs 450h+
The NX 350h Premium starts at $46,515 while the 450h+ is $58,755. That $12,240 gap buys 5 meaningful differences.
This trim jump changes the engine from 2.5L I4 hybrid to 2.5L I4 phev. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 2.5L I4 phev every week, the 450h+ makes sense. If not, the 350h Premium 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 $216/month more over 60 months, or roughly $12,960 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.
