Lexus RX trim comparison
2025 Lexus RX 350h F SPORT Design vs 450h+ Luxury
The RX 350h F SPORT Design starts at $56,005 while the 450h+ Luxury is $71,260. That $15,255 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.
Start with the 350h F SPORT Design if the 2.5L I4 hybrid already feels sufficient for the way you drive. Step up to the 450h+ Luxury only when the 2.5L I4 phev powertrain is the reason you are moving higher in the lineup.
The cleanest way to feel this upgrade is through the payment: about $269/month more over 60 months, or roughly $16,140 extra all-in once interest is included. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
