Lexus TX Vs. GX: A Side-By-Side SUV Comparison
Let's compare the Lexus TX vs. GX! The difference between Lexus TX and GX SUVs is woven into the fabric of their beings. While the TX is a luxury family travel companion, the GX proves its worth off-road. They share a few accolades, like placing high on Car and Driver's "Best Midsize 3-Row Luxury SUV" list,1 but in nearly every other way, these automotive siblings couldn't be more unique.
Before you test-drive either model at DARCARS Lexus of Mt. Kisco, let's take a look at each sport-ute in depth, so you can decide which is the best Lexus SUV for your lifestyle.
Lexus TX vs. Lexus GX at a Glance
The TX and GX share the Lexus badge – but almost nothing else. Here's a quick highlight reel of how they stand out:
- The GX is equipped with full-time 4WD.
- The TX achieves better fuel economy.
- Expect better towing capacity with the GX.
- The highest three-row cargo space goes to the TX.
Lexus TX Overview
If a family hauler with three rows in every trim is your druthers, the TX more than answers the call. The entry powertrains of the Lexus TX 350 are gas-only models. Spend a little more on a hybrid powertrain by choosing a Lexus TX 500h trim, and you'll see that your MPG goes up while emissions go down. For maximum travel power, opt for the top-spec PHEV variant.
Throughout the 2026 lineup, Lexus TX towing capacity remains a helpful 5,000 pounds,2 and the Lexus TX cargo space is more than ample at 20.2 cubic feet. Enjoy the following standard amenities:
- Heated steering wheel
- Heated front seats
- Wireless phone charging
- 12.3-inch center display
- Power rear door with kick sensor
We'll explore more about these Lexus TX specs and features below.
Lexus GX Overview
Most Lexus GX competitors are built with a unibody, but the GX goes all-in on off-roading with its more durable body-on-frame construction. While every 2026 GX variant is ready for adventure with a V-6 engine, the Lexus GX 550 Overtrail trim stands out with its 33-inch all-terrain tires.
Other Lexus GX off-road perks include an onboard air compressor and a pre-wired auxiliary switch bank. You'll notice that the Lexus GX 550 interior promises:
- Standard heated leather steering wheel
- Standard ambient illumination
- Standard power tilt-and-slide moonroof
- 14-inch center touchscreen
- Intuitive Parking Assist
We'll dig deeper into the Lexus GX, including the Lexus GX towing capacity, as you scroll.
Head-to-Head: Key Differences of the Lexus TX vs. Lexus GX
Seating Capacities
Every version of the 2026 TX has a three-row cabin, but you can flex its interior by choosing a trim level with captain's chairs rather than a second-row bench, and there's typically more than enough legroom to buckle car seats into any second-row configuration. The GX interior is a bit different: Most trim levels have three rows, but both Overtrail models come with only two.
Trim Levels
We're impressed at how thoughtfully all 10 TX trims are equipped: No need to pay extra for a wireless charging pad, voice command, or Traffic Jam Assist when these amenities come standard.
You'll have six trim options in the GX. NuLuxe upholstery wraps the family in plush, easy-clean comfort, and a 10-speaker premium sound system is also standard. We particularly love the GX 550 Overtrail trim for its available Cool Box that keeps your beverages chilled on long trips.
Fuel Economy
Well-suited for family errands, a gas-powered TX earns an EPA-estimated 23 MPG (Combined)3 and hybrid variants deliver an EPA-estimated 27 MPG (Combined).4 The TX plug-in hybrid setup is fantastic for road trips with an EPA-estimated 76 MPGe (Combined)5 that includes 33 miles of all-electric range.6
The GX doesn't get quite the same level of gas mileage, but this is due to heavier components and equipment that make it better suited for off-roading. Its V-6 engine, standard across all trim levels, earns an EPA-estimated 17 MPG (Combined)7 – but who's counting mileage when you're carving your way down a trail with 479 pound-feet of torque under the hood?
Dimensions & Cargo Space
This year's Lexus TX has the honor of winning the brand's "Which Lexus SUV is the biggest?" crown. Designed for maximum comfort, the TX offers 39.5 inches of legroom in row two. The TX trunk is a roomy 20.2 cubic feet, perfect for suitcases, groceries, and other Mt. Kisco necessities.
In comparison, the new GX has a smaller 10.3 cubic feet of trunk space in its three-row configuration, but this sacrifice in the cargo area means third-row legroom is a comfy 37.89 inches. You can gain far more storage in the GX by choosing a two-row model, and remember that you can also bring along supplies on a trailer.
Towing & Off-Road Capability
Towing and off-roading are not a Lexus TX speciality, though it can trailer up to 5,000 pounds.2 Because the TX is equipped with a multilink suspension and four-wheel power disc brakes, it's most at home on pavement, and its welded-steel unibody gives you the utmost protection in case of a collision.
If carting around motorcycles or ATVs is your version of a dream weekend, the GX offers up to 9,096 pounds of towing strength.2 Ventilated discs on all four wheels generate supreme stopping power, and rocky terrain feels even smoother thanks to features like adaptive variable suspension with gas-pressurized shock absorbers on the Overtrail models.
