2026 Lexus LX 600 vs 2026 Lexus GX 550: Flagship vs Midsize Luxury Off-Road SUV
The 2026 Lexus LX 600 and 2026 Lexus GX 550 share more than a badge. Both ride on a body-on-frame GA-F platform, and both use a 3.4L twin-turbo V6 with a 10-speed Direct Shift automatic. They still serve different buyers. The LX 600 is the Lexus flagship SUV, with 409 hp and seven seats in the F SPORT Handling grade. The GX 550 Overtrail is a dedicated five-passenger, off-road-focused version of the midsize GX. It tows up to 9,096 lbs and starts at an MSRP about $39,000 below the LX 600 F SPORT Handling.

Which 2026 Lexus SUV Fits Your Life?
