Lexus RX or TX: which fits Orange County drivers?

Choose the Lexus RX if two rows of seats cover your household and you want the smaller of the two SUVs. Choose the Lexus TX if you regularly carry more people than two rows hold and want a third row.

Tustin Lexus carries both, at 45 Auto Center Dr, Tustin, CA 92782.

Choose the Lexus RX or TX by how many people you carry

The RX seats five on every 2026 trim Lexus lists. The TX seats seven on the TX 350 and TX 350 AWD, six or seven on the Premium and Luxury trims, and six on the F SPORT and hybrid trims.

The third row is the real difference. In the TX 350, third-row legroom is 33.50 inches, compared with 39.50 inches in the second row, according to Lexus’s 2026 specifications. If your household fills all seven seats, the RX cannot carry everyone.

The RX suits couples and smaller households. In a May 2026 Google review, Curtis S. wrote: “We had a very good experience buying our Lexus RX at Tustin Lexus. David was very professional, patient, very knowledgeable and helpful. Barron also with our trade-in. And Greg with the paperwork and financing, he did everything including DMV. We love our new Lexus. A beautiful car. I also appreciate all the help from Lisa who texted with me over a week answering all my questions and setting up an appointment.”

How much longer and wider is the Lexus TX than the RX?

The TX has the longer wheelbase, at 116.14 inches against 112.2 inches for the RX. The TX measures 78.35 inches wide and 70.08 inches tall, and the RX is 192.5 inches long, according to Lexus’s 2026 specifications.

The longer wheelbase is what gives the TX room for a third row. The RX offers five seats, so it has no third row to make room for.

How much cargo space do the Lexus RX and TX have?

The TX offers up to 97 cubic feet of maximum cargo room, according to Lexus’s 2026 specifications. Behind the second row it carries 57.4 cubic feet, and behind the third row it carries 20.2 cubic feet.

Those figures matter most to a household that uses all three rows. A household that only needs two rows does not need the third-row space, and the TX’s cargo figures are the reason to choose it when a family does.

What are the EPA fuel economy ratings for the Lexus RX and TX?

On gasoline, the RX 350 Front-Wheel Drive is rated 22 city, 29 highway and 25 combined. These are EPA certified figures for the 2026 model year.

The hybrids rate higher. The RX 350h AWD is rated 37 city, 34 highway and 36 combined, and the TX 500h AWD is rated 27 city, 28 highway and 27 combined.

Under 40 CFR part 600, subpart D, the EPA combined figure is a harmonic average of city and highway values weighted 0.55 and 0.45. The combined number therefore weighs city driving a little more. For daily driving through Orange County traffic, the RX 350h AWD has the highest combined rating of the RX and TX models listed here.

What does a new Lexus RX cost compared with a TX?

Lexus lists starting MSRPs from $52,775 for the RX 350 Standard FWD to $73,410 for the RX 450h+ Luxury AWD. For the TX, the range runs from $58,490 for the TX 350 to $82,160 for the TX 550h+ Luxury AWD, according to Lexus’s 2026 pricing.

The TX starts above the RX at both ends of the range. Set the starting price against the seats you need: the RX 350 Standard FWD is the entry point for a five-seat household, and the TX 350 is the starting model for seven seats.

What do the RX and TX each offer in seats, cargo, towing and price?

Lexus lists these five 2026 models with their seats and starting MSRP.

The TX 350 tows up to 5,000 lbs, and so do the TX 500h F SPORT Performance trims, according to Lexus’s 2026 specifications. The TX 350 also carries 97 cubic feet of maximum cargo room, and the RX seats five on every trim.

When is the Lexus RX the wrong pick, and when is the TX?

The RX is the wrong pick when your household fills seven seats or regularly needs a third row. The TX 350 seats seven, so it is the right pick for that household.

The TX is also the right pick when you tow. The TX 350 and the TX 500h F SPORT Performance trims carry a 5,000 lbs maximum tow rating in Lexus’s 2026 specifications.

For Orange County drivers, the choice comes down to seats and parking. The RX, at 192.5 inches long, is the more compact of the two, and it fits packed parking structures and tight residential streets more easily. The TX asks for more care in tight garages. Pick the RX for daily driving and two-row needs, and pick the TX when the third row gets regular use.
