The 2026 Lexus GX and 2026 Lexus TX are both three-row luxury SUVs, but they are built on opposite engineering philosophies. The GX is a body-on-frame SUV with standard full-time four-wheel drive, a 349-hp twin-turbo V6, and up to 9,096 pounds of towing capacity. The TX is a unibody crossover offered with gas, hybrid, and plug-in hybrid powertrains, a lower step-in height, and more cargo volume than the GX. Which one fits depends less on which is better and more on what you tow, where you drive, and how much fuel matters.
Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
The GX suits drivers who tow, who load up for weekend trips toward the Sierra Nevada, or who want a traditional truck-based SUV with Lexus refinement. The TX suits households that spend most of their miles on pavement around Fresno, Clovis, and Madera and want three usable rows with efficiency to match.
The 2026 Lexus GX uses body-on-frame construction. Full-time four-wheel drive is standard on every grade, and so is a Torsen limited-slip locking center differential. The Overtrail and Overtrail+ grades add an electronically controlled locking rear differential and a one-inch suspension lift. That lift raises minimum running ground clearance to 9.84 inches. Approach, breakover, and departure angles reach up to 26, 24, and 21 degrees. Premium, Premium+, Luxury, and Luxury+ seat up to seven passengers, with a second row available as captain’s chairs or a 60:40 split bench.
The 2026 Lexus TX uses unibody construction and rides lower, with 7.9 inches of ground clearance. It seats six or seven depending on grade and second-row configuration. That makes it the more natural choice for school runs, highway commutes, and families who prioritize interior volume over trail hardware.
The GX is offered in six grades, all sharing the same powertrain. The TX is offered across three distinct powertrains, which is the structural difference that matters most when comparing the two.
Premium, Premium+, Luxury, Luxury+, Overtrail, and Overtrail+. Every grade uses the 3.4L twin-turbo V6 with full-time four-wheel drive, so the ladder is about equipment and off-road hardware rather than performance.
The TX 350 is available in Standard, Premium, Luxury, and F SPORT Handling AWD configurations with front- or all-wheel drive. The TX 500h F SPORT Performance is offered in Premium and Luxury grades with DIRECT4 all-wheel drive. The TX 550h+ Luxury is the plug-in hybrid, also with DIRECT4 all-wheel drive. Grade and powertrain details come from Lexus.
For a deeper look at how the grades are equipped, see our 2026 Lexus TX trims and pricing guide.
The GX leads on power and towing. The TX counters with three powertrains, two of them electrified.
The 2026 Lexus GX produces 349 horsepower and 479 lb-ft of torque from its 3.4L twin-turbo V6. That full 479 lb-ft arrives at 2,000 rpm, which is what makes the GX pull hard from a standstill with a trailer behind it. A 10-speed Direct Shift automatic transmission handles the gear changes. Towing reaches up to 9,096 pounds on the Overtrail and 9,063 pounds on Premium, Premium+, and Overtrail+ with the standard tow hitch receiver, according to Lexus. If towing is the deciding factor, our 2026 Lexus GX towing capacity guide covers it in more detail.
Maximum towing and payload capacity figures are based on properly equipped vehicles and vary by configuration. Do not exceed any weight rating. See your owner’s manual and the vehicle’s door-jamb label for specific capacities.
The 2026 Lexus TX 350 pairs a 2.4L turbocharged four-cylinder making 275 horsepower and 317 lb-ft with an eight-speed automatic. The TX 500h F SPORT Performance uses a 2.4L turbocharged parallel hybrid system. It is rated at 366 total system horsepower and 406 lb-ft, with a six-speed automatic and DIRECT4 all-wheel drive. The TX 550h+ is a 3.5L V6 plug-in hybrid rated at 404 total system horsepower driving through a two-motor transaxle. Every TX is rated to tow up to 5,000 pounds, which our Lexus TX towing capacity page breaks down further.

The TX carries more cargo. The GX offers a taller, more upright cabin and the hardware to use it off pavement.
In the 2026 Lexus GX, cargo space measures 10 cubic feet behind the third row. That grows to 40 cubic feet behind the second row and 77 cubic feet behind the first. Front headroom is about 40 inches, with roughly 41 inches of front legroom. Second-row headroom is about 42 inches. Third-row passengers get about 35 inches of headroom and 38 inches of legroom.
The 2026 Lexus TX stretches further in every cargo measure. It holds 20.2 cubic feet behind the third row, 57.4 cubic feet with the third row folded, and 97 cubic feet with the second and third rows folded. Second-row headroom measures 38.5 inches with 39.5 inches of legroom.
Efficiency is the clearest separation between these two SUVs, and it widens considerably once the electrified TX models enter the picture.
The 2026 Lexus GX carries an EPA-estimated 15 MPG city, 21 MPG highway, and 17 MPG combined across the lineup. It draws from a 21.1-gallon tank and runs on premium fuel.

The 2026 Lexus TX 350 is EPA-estimated at 21 MPG city, 27 MPG highway, and 23 MPG combined in front-wheel drive. With all-wheel drive it is EPA-estimated at 20 MPG city, 26 MPG highway, and 23 MPG combined. Both draw from a 17.8-gallon tank.

The electrified grades widen the gap. The TX 500h is EPA-estimated at 27 MPG city, 28 MPG highway, and 27 MPG combined. The TX 550h+ plug-in hybrid is EPA-estimated at 29 MPG combined on gasoline once its battery is depleted. It also adds a Lexus-projected 33 miles of electric driving range, which covers a typical Fresno-area commute before the gas engine is needed at all.

Both SUVs share the same core interface. A 14-inch Lexus Interface touchscreen and a 12.3-inch digital multi-information display are standard on the GX and the TX, and wireless Apple CarPlay and Android Auto are standard.
The 2026 Lexus GX pairs a standard 10-speaker premium audio system with an available 21-speaker Mark Levinson Surround Sound system on higher grades. It offers six illuminated charging ports, four on Overtrail and Overtrail+, along with a wireless charger in the front console tray and a 120V AC inverter. A Head-Up Display is available depending on grade. Entry includes a SmartAccess Card Key, plus available Digital Key, which requires an active Remote Connect trial or subscription.
The 2026 Lexus TX offers seven USB ports and up to three power outlets depending on grade, and the 21-speaker Mark Levinson system is available here as well.
Lexus Safety System+ 3.0 is standard on every 2026 Lexus GX and every 2026 Lexus TX. The suite includes the Pre-Collision System with Pedestrian Detection, Risk Avoidance Emergency Steer Assist, Left Turn Oncoming Vehicle Detection and Braking, and Full-speed Dynamic Radar Cruise Control. It also adds Lane Tracing Assist, Lane Departure Alert with Steering Assist, Emergency Driving Stop System, Road Sign Assist, and Proactive Driving Assist.

Yes. The 2026 Lexus GX seats up to seven passengers on Premium, Premium+, Luxury, and Luxury+, with a second row available as captain’s chairs or a 60:40 split bench. The 2026 Lexus TX seats six or seven depending on grade and second-row configuration.
Six: Premium, Premium+, Luxury, Luxury+, Overtrail, and Overtrail+. All six share the same 3.4L twin-turbo V6 and full-time four-wheel drive, so the differences come down to equipment and off-road hardware rather than performance.
Choose the 2026 Lexus GX if you tow. It also fits if you want body-on-frame construction and full-time four-wheel drive, or if the Overtrail hardware matches how you actually use an SUV. Choose the 2026 Lexus TX if you want maximum cargo volume and a lower step-in height. It is also the only one of the two offered as a hybrid or plug-in hybrid for daily driving around the Central Valley.
