Lexus GX or TX: which fits Orange County drivers?

Choose the TX if you carry passengers and cargo most days, and the GX if you tow. Tustin Lexus on Auto Center Drive sells both, along with the TX Hybrid.

Tustin Lexus is at 45 Auto Center Drive, Tustin, CA 92782. The figures below are Lexus’s 2026 model year specifications and EPA certified ratings, and each one belongs to the trim it names.

Keep reading below, then schedule a test drive in Tustin. Bringing your own numbers to the lot settles this faster than any spec sheet.

Pick the Lexus TX for passengers and cargo, the GX for towing

The TX 350 seats seven and offers 97 cubic feet of maximum cargo room.

For passengers, the TX gives more legroom in all three rows that Lexus measures: 41.68, 39.50 and 33.50 inches. The GX measures 41.18, 36.73 and 31.89 inches. A family that fills the seats and loads luggage most days will find more room in the TX.

If you tow a trailer, the GX is the model to start with. A trailer is an ordinary towing load, and the GX has the higher rating. Tustin Lexus sells both models, so you can sit in each one before you decide.

How do the Lexus GX and TX compare on price, seats, cargo and towing?

The GX 550 Premium starts at $68,335 and the TX 350 starts at $58,490, both as Lexus publishes them for the 2026 model year. The two models split on towing and cargo, and the warranty is the same for both.

The table puts the two trims side by side on the measures that drive the choice. The TX offers twice the cargo behind the third row, and the GX offers the towing rating. The GX starts higher, so the extra cost buys the towing capacity.

How many seats and how much cargo room do the GX and TX have?

The TX 350 seats seven, with 57.4 cubic feet behind row 2 and 20.2 behind row 3. The GX 550 Premium seats seven with the bench or six with captain’s chairs, and it has 10.3 cubic feet behind row 3.

The GX 550 Overtrail is the exception in the GX lineup. It seats five and has 45.6 cubic feet behind row 2, which suits buyers who want cargo space more than a third row.

Consumer Reports requires a three-row SUV to have 46 cubic feet or more of usable cargo room to qualify for its most-cargo-room rankings (Consumer Reports, 2026). Buyers who load the third row often should confirm the cargo measure they care about in the TX before they choose.

How much can the Lexus GX and TX tow?

The GX 550 Overtrail tows 9,096 pounds, the highest towing figure in the 2026 GX lineup. The GX 550 Premium tows 9,063 pounds. The GX 550 Luxury tows 7,844 to 8,020 pounds, depending on seating configuration, and the Luxury+ tows 7,601 to 7,800 pounds on the same basis.

Every TX trim listed in the 2026 specifications tows 5,000 pounds. If your trailer weight is above that, the TX is not the right tow vehicle, and the GX is the model in our lineup for that need.

If towing is the main reason you are shopping, start with the GX 550 Overtrail. It gives the highest rating and the most towing capacity of any GX trim, though it seats five.

What are the EPA fuel economy ratings for the GX, TX and TX Hybrid?

The EPA certifies the GX 550 4-Wheel Drive at 15 city, 21 highway and 17 combined mpg. The TX 350 front-wheel drive is rated 21 city, 27 highway and 23 combined. The TX 500h all-wheel drive hybrid is rated 27, 28 and 27.

Among the three, the TX 500h has the highest combined rating, at 27 mpg. The gasoline TX models sit at 23 combined, and the GX at 17. A driver who wants the best fuel economy in this comparison will look at the TX Hybrid first.

What do the Lexus GX and TX cost to start, and what warranty comes with each?

The GX starts at $68,335 for the GX 550 Premium. The TX starts at $58,490 for the TX 350. Stepping up in the GX lineup reaches $84,800 for the GX 550 Luxury+.

Both models carry the same new-vehicle coverage from Lexus: a basic warranty of 48 months or 50,000 miles, and a powertrain warranty of 72 months or 70,000 miles, whichever occurs first in each case. Corrosion coverage runs 72 months regardless of mileage. Roadside assistance runs 48 months from the in-service date, regardless of mileage.

Because the warranties match, the price gap and the towing and cargo figures are the deciding factors. Buyers who want the towing rating pay more for the GX, and those who want the TX’s cargo room pay less.

When is the Lexus GX or the TX the wrong choice for you?

The TX is the wrong choice if you tow more than 5,000 pounds. The GX is the wrong choice if you need the most cargo room behind the third row, since it offers 10.3 cubic feet there.

If your trailer is heavier than the TX can tow, the GX is the right model, and the GX 550 Overtrail gives the most towing capacity. If you need a full third row and a lot of cargo room behind it, the TX is the right model. If neither model fits the need, Tustin Lexus also sells the NX and RX.
