Lexus RX trim comparison
2026 Lexus RX 350 Premium Plus vs 500h F SPORT Performance
The RX 350 Premium Plus starts at $56,190 while the 500h F SPORT Performance is $66,200. That $10,010 gap buys 8 meaningful differences.
This is a powertrain and drivetrain change. The 500h F SPORT Performance gets the 2.4L I4 hybrid Turbo and AWD, so the $10,010 is buying a different driving experience, not just nicer trim.
This is a real hardware fork, not just a trim-label shuffle. The 350 Premium Plus is enough if the 2.4L I4 Turbo with FWD already fits your routine; the 500h F SPORT Performance only earns the jump when the 2.4L I4 hybrid Turbo and AWD setup is the point of the upgrade.
Think about this as a monthly tradeoff, not just a sticker gap. The 500h F SPORT Performance adds about $177/month on a typical 60-month loan, or around $10,620 more overall with interest. 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.
