Lexus RX trim comparison
2024 Lexus RX 350 F SPORT vs 450h+ Luxury
The RX 350 F SPORT starts at $57,200 while the 450h+ Luxury is $69,230. That $12,030 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.4L I4 Turbo to 2.5L I4 phev. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the 350 F SPORT if the 2.4L I4 Turbo 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 $212/month more over 60 months, or roughly $12,720 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.
