Lexus RX trim comparison
2025 Lexus RX 350 Premium Plus vs 350h F SPORT Design
The RX 350 Premium Plus starts at $54,865 while the 350h F SPORT Design is $56,005. That $1,140 gap buys 8 meaningful differences.
This is a powertrain and drivetrain change. The 350h F SPORT Design gets the 2.5L I4 hybrid and AWD, so the $1,140 is buying a different driving experience, not just nicer trim.
Choose the 350 Premium Plus if the 2.4L I4 Turbo with FWD already covers the way you drive. Move to the 350h F SPORT Design only when the 2.5L I4 hybrid and AWD combo is the reason you are shopping higher, because that is the real hardware split here.
The cleanest way to feel this upgrade is through the payment: about $20/month more over 60 months, or roughly $1,200 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.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
