Lexus TX trim comparison
2026 Lexus TX 350 vs 550h+ Luxury
The TX 350 starts at $56,440 while the 550h+ Luxury is $80,310. That $23,870 gap buys 7 meaningful differences.
This is a powertrain and drivetrain change. The 550h+ Luxury gets the 3.5L V6 phev and AWD, so the $23,870 is buying a different driving experience, not just nicer trim.
Choose the 350 if the 2.4L I4 Turbo with FWD already covers the way you drive. Move to the 550h+ Luxury only when the 3.5L V6 phev and AWD combo is the reason you are shopping higher, because that is the real hardware split here.
Think about this as a monthly tradeoff, not just a sticker gap. The 550h+ Luxury adds about $420/month on a typical 60-month loan, or around $25,200 more overall with interest. 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.
