Lexus RX trim comparison
2026 Lexus RX 350 Premium vs 350h F SPORT Design
The RX 350 Premium starts at $52,700 while the 350h F SPORT Design is $57,330. That $4,630 gap buys 9 meaningful differences.
This is a powertrain and drivetrain change. The 350h F SPORT Design gets the 2.5L I4 hybrid and AWD, so the $4,630 is buying a different driving experience, not just nicer trim.
Choose the 350 Premium 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.
If you are budgeting this move monthly, the jump from the 350 Premium to the 350h F SPORT Design is about $82/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $4,920 more by the time interest is counted. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
