Lexus GX 550 vs Lexus LX
Specs on this page are awaiting verification.
We don't publish numbers we haven't sourced.
Summary
Both third rows are configuration-dependent. The GX 550's Overtrail and Overtrail+ are five-seat two-row builds; the three-row grades offer a seven-seat bench or six-seat captain's chairs. The LX sells as a 7-seat three-row, a 5-seat two-row, or the 4-seat Ultra Luxury two-row — and its second row is a bench in every case.
The specs are far closer than the prices: third-row legroom 31.89 vs 31.1 in, third-row headroom 35.45 vs 35.24, cargo behind row 3 10.3 vs 11 cu ft. The GX out-tows the LX (9,096 vs 8,000 lb — the dataset's highest rating) and carries more with seats folded (76.9 vs 64 cu ft, the dataset's smallest max-cargo figure). The GX spans $68,335–$84,800; the LX spans $108,050–$142,550, both including the $1,550 delivery fee.

Configuration caveats on both sides
The GX 550's third row arrives on Premium, Premium+, Luxury, and Luxury+ — bench for seven or captain's chairs for six — while the Overtrail and Overtrail+ are five-seat two-rows. The LX offers three cabins: a seven-seat three-row, a five-seat two-row, and the four-seat Ultra Luxury two-row. No six-seat LX exists, so its seven-seat second row is always a bench.
Note what that means at the top of the LX ladder: the $142,550 ceiling is the LX 700h Ultra Luxury, a four-seat two-row build. The most expensive LX is not a three-row SUV at all.
Third-row reality
This is the surprise of the comparison: the cheaper truck measures slightly larger. GX third-row legroom is 31.89 in against the LX's 31.1; headroom is 35.45 (the Moon Roof basis — the Luxury+ Dynamic Sky roof reads 35.28) against 35.24. Both gaps are under an inch, so treat the rows as equivalent: occasional-use, not adult-commute.
Child-seat hardware follows the same order. Neither model puts lower anchors in the third row, and the GX's bench has no third-row top tether either — but its captain's-chair configuration adds one on the right-hand third seat. The LX's owner's manual provides tether anchors on the second row only.
Cargo capacity
Behind the third row the two are near-equal: GX 10.3 cu ft — the smallest behind-row-3 figure in this dataset — and LX 11. Folded, they separate: the GX reaches 76.9 cu ft while the LX's three-row configuration tops out at 64, the smallest max-cargo figure in this dataset. The GX's 12.9 cu ft advantage is the difference between a full home-store run fitting or not.
One publication gap to flag: Lexus publishes no behind-row-2 cargo figure for the LX's three-row configuration, so that comparison cell stays honestly empty. The GX's figure is 40.2 cu ft.
Towing capacity
The GX 550 holds the highest tow rating in this dataset: 9,096 lb on the Overtrail grade, with Premium, Premium+, and Overtrail+ published at 9,063. The LX is rated at 8,000 lb with its Towing Package specification.
Worth naming: the GX's headline 9,096 belongs to the two-row Overtrail, but even the published 9,063 lb on three-row-capable grades clears the LX by more than 1,000 lb. On this axis the junior truck simply wins.
Pricing and the hybrid line
The GX 550 spans $68,335 (Premium) to $84,800 (Luxury+). The LX opens at $108,050 for the gas LX 600 Premium and the LX 700h hybrid line rises above it to $142,550 for the Ultra Luxury. All of these figures include Lexus's $1,550 delivery fee, so the floors sit a clean $39,715 apart.
The ladders never touch: a fully loaded GX 550 Luxury+ remains $23,250 below the cheapest LX. What the extra money buys is the flagship badge, the hybrid option, and the Ultra Luxury cabin — not third-row space, cargo, or towing, where the GX matches or beats it.
When each one fits
Lexus GX 550: The rational pick on the data in this comparison — it equals or beats the LX on third-row space, cargo, and towing while starting $39,715 lower. Configure a Premium, Premium+, Luxury, or Luxury+ for the third row, and remember the Overtrail trims are two-row builds.
Lexus LX: The flagship badge, the LX 700h hybrid powertrain, or the four-seat Ultra Luxury cabin is the point — and the third row is occasional enough that 64 cu ft of maximum cargo and no third-row child-seat anchors are acceptable trades at a $108,050-plus price.
