2026 Lexus GX 550 vs 2026 Lexus TX 350: Which Three-Row Lexus SUV Fits Your Family?
Lexus builds two very different three-row SUVs, and both sit in the same showroom. One rides on a rugged, truck-based frame built for real capability. The other uses a car-based platform tuned for a smooth, quiet highway ride. Comparing them shows how Lexus matches engineering to different family routines.
At a Glance: Which One Fits You
| If you… | Better fit |
|---|---|
| Tow more than 5,000 pounds | GX 550 |
| Use the third row every day | TX 350 |
| Want the lowest entry price | TX 350 |

| Want the most cargo room behind the second row | TX 350 |
Why Encino and Tarzana Families Compare the GX 550 and TX 350
San Fernando Valley drivers sit unusually close to open space. Trailheads along the northern edge of the Santa Monica Mountains are minutes away. The Caballero Canyon trailhead sits on Reseda Boulevard in Tarzana. Marvin Braude Mulholland Gateway Park anchors 1,500 acres at the southern end of that same street. Corbin Canyon Park is reachable from the ends of Corbin Avenue and Queen Victoria Road.
Families here need one vehicle for two jobs. It has to handle school drop-offs on Monday and a fully loaded departure on Saturday.
The GX 550: built for the weekend
For households that spend weekends at those trailheads, the 2026 Lexus GX 550 offers real mechanical capability. It is built on the GA-F ladder-frame platform shared with the LX, so a strengthened frame sits under a refined cabin. It suits buyers who want a commanding driving position, serious towing capacity, and hardware that stands up to gear, roof racks, and long distances.
The TX 350: built for the week
The 2026 Lexus TX 350 takes the opposite approach. It is a spacious, road-focused family SUV designed around commuting, errands, and passenger comfort. If you do not need off-road hardware or heavy towing, the TX 350 delivers a relaxed, low-effort drive.
Comparing Price and Trim Value
These two models sit in different tiers of the Lexus SUV range. Their pricing reflects different engineering priorities.
2026 Lexus GX 550 grades and pricing
The GX 550 comes in six grades. Pricing reflects its body-on-frame construction, standard full-time four-wheel drive, and standard twin-turbocharged V6. For a grade-by-grade breakdown, see our 2026 Lexus GX 550 pricing and trim guide. Grade lineup and pricing are published by Lexus in its 2026 GX product release.
| 2026 Lexus GX 550 Grade | Seating | Starting MSRP |
|---|---|---|
| Premium | 7 | $68,335 MSRP |
| Premium+ | 7 | $72,800 MSRP |
| Overtrail | 5 | $75,980 MSRP |
| Luxury | 7 | $80,800 MSRP |
| Overtrail+ | 5 | $83,445 MSRP |
| Luxury+ | 7 | $84,800 MSRP |
2026 Lexus TX 350 grades and pricing
The TX 350 offers a more accessible entry into the three-row luxury segment. It comes in four grades, with front-wheel drive standard on most and all-wheel drive available. Grade lineup and pricing are published by Lexus in its 2026 TX product release.
| 2026 Lexus TX 350 Grade | Drivetrain | Starting MSRP |
|---|---|---|
| TX 350 | FWD standard, AWD available | $58,490 MSRP |
| TX 350 Premium | FWD standard, AWD available | $61,290 MSRP |
| TX 350 Luxury | FWD standard, AWD available | $63,640 MSRP |
| TX 350 F SPORT Handling | AWD standard | $67,760 MSRP |
Manufacturer’s Suggested Retail Price (MSRP) for new vehicles includes manufacturer and distributor options and delivery, process and handling fees, which may be subject to change at any time. MSRP excludes taxes, title, license and dealer installed options, accessories, fees and charges. MSRP is not the dealer advertised price. Dealer price will vary. The dealer sets the final price.
Every GX 550 grade shares the same twin-turbo V6 and 10-speed automatic. The price difference between grades buys interior materials, technology, and off-road hardware rather than performance. The Overtrail and Overtrail+ grades trade the third row for a two-row layout and off-road equipment. The TX 350 is strong value for families who want interior volume, since it opens the three-row unibody luxury segment at a competitive price.
Cargo and Passenger Space for an Active Family
GX 550 cargo and seating
The GX 550 configures its interior differently by grade. Premium, Premium+, Luxury, and Luxury+ seat up to seven. Because the vehicle is body-on-frame, cargo space behind the third row is limited to 10.3 cubic feet. Folding the third row opens 40.2 cubic feet, and dropping both rear rows reaches 76.9 cubic feet.
Buyers who value gear space over passenger count can choose the Overtrail or Overtrail+ grades. These are five-passenger, two-row models with 45.6 cubic feet behind the second row and 90.5 cubic feet with that row folded. Our 2026 Lexus GX 550 overview covers the grade-level differences in more depth.
TX 350 cargo and seating
The TX 350 is a study in space efficiency. Its unibody construction allows a lower floor and a more open cabin. Even with all three rows up, it provides 20.2 cubic feet behind the third row. That grows to 57.4 cubic feet with the third row folded and 97 cubic feet with both rear rows down. Groceries, sports gear, and luggage can travel together.
| Specification | 2026 Lexus GX 550 | 2026 Lexus TX 350 |
|---|---|---|
| Seating | 7 (Premium, Premium+, Luxury, Luxury+); 5 (Overtrail, Overtrail+) | Up to 7 |
| Cargo behind third row | 10.3 cu ft | 20.2 cu ft |
| Cargo, third row folded | 40.2 cu ft | 57.4 cu ft |
| Maximum cargo | 76.9 cu ft (three-row grades); 90.5 cu ft (Overtrail, Overtrail+) | 97 cu ft |
If you use the third row daily, the TX 350 gives you more usable cargo room behind it. If you treat your SUV as a basecamp, the two-row GX 550 Overtrail grades offer a more durable hold.
Performance and Driving Feel
GX 550 powertrain and towing
The GX 550 runs a 3.4-liter twin-turbocharged V6 rated at 349 horsepower and 479 lb-ft of torque. It pairs with a 10-speed Direct Shift automatic and standard full-time four-wheel drive. A Torsen limited-slip locking center differential is standard on every grade. It splits power evenly to help you keep control in low-grip conditions.
Properly equipped, the GX 550 tows up to 9,096 pounds in Overtrail configuration. Premium, Premium+, and Overtrail+ configurations are rated at 9,063 pounds.
TX 350 powertrain and towing
The TX 350 is engineered for refined road manners. Its 2.4-liter turbocharged inline-four produces 275 horsepower and 317 lb-ft of torque through an eight-speed Direct Shift automatic. Front-wheel drive is standard on the TX 350, Premium, and Luxury grades, and all-wheel drive is available on each. The F SPORT Handling grade comes standard with all-wheel drive and with Adaptive Variable Suspension. The TX 350 is rated to tow up to 5,000 pounds.
| Specification | 2026 Lexus GX 550 | 2026 Lexus TX 350 |
|---|---|---|
| Engine | 3.4L twin-turbocharged V6 | 2.4L turbocharged inline-4 |
| Horsepower | 349 hp | 275 hp |
| Torque | 479 lb-ft | 317 lb-ft |
| Transmission | 10-speed automatic | 8-speed automatic |
| Drivetrain | Full-time four-wheel drive, standard | Front-wheel drive standard; all-wheel drive available or standard by grade |
| Maximum towing | 9,096 lbs (Overtrail); 9,063 lbs (Premium, Premium+, Overtrail+) | 5,000 lbs |
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 TX 350 is easier to place in tight suburban parking and rides quieter over rough pavement. The GX 550 offers mechanical capability the crossover is not built to match.
Fuel Efficiency for Daily Driving
Not every large SUV asks for the same compromise at the pump. The TX 350 pairs unibody construction with a turbocharged four-cylinder, and the efficiency shows. Front-wheel-drive grades carry an EPA-Estimated 21 city / 27 highway / 23 combined MPG rating. All-wheel-drive configurations are rated at an EPA-Estimated 20 city / 26 highway / 23 combined MPG.
The GX 550 prioritizes capability instead. Between the twin-turbocharged V6, full-time four-wheel drive, and body-on-frame structure, every grade carries an EPA-Estimated 15 city / 21 highway / 17 combined MPG rating. You can compare official ratings for both models at fueleconomy.gov.
| EPA-Estimated Rating | 2026 Lexus GX 550 | 2026 Lexus TX 350 |
|---|---|---|
| EPA-Estimated city MPG | 15 | 21 (FWD); 20 (AWD) |
| EPA-Estimated highway MPG | 21 | 27 (FWD); 26 (AWD) |
| EPA-Estimated combined MPG | 17 | 23 |
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
If you are focused on daily fuel costs across a long commute, the TX 350 is the more economical choice. If you need heavy towing and four-wheel-drive traction, the GX 550 fuel figure is the trade-off for what it can do.
Advanced Safety and Driver Assistance
Standard on both: Lexus Safety System+ 3.0
Both SUVs come standard with Lexus Safety System+ 3.0. It is an integrated suite of active safety and driver-assist technologies. Standard content includes:
- Pre-Collision System with Pedestrian Detection
- Risk Avoidance Emergency Steer Assist
- Left Turn Oncoming Vehicle Detection and Braking
- Dynamic Radar Cruise Control
- Lane Tracing Assist
- Lane Departure Alert with Steering Assist
- Road Sign Assist
- Proactive Driving Assist
- Emergency Driving Stop System
What each model adds
The GX 550 adds the Multi-Terrain Monitor. When Multi-Terrain Select is engaged, it uses four cameras within the Panoramic View Monitor system to show underfloor, front, side, and rear views on the 14-inch display. That helps you judge obstacles and clearance off pavement.
The TX 350 includes a standard Digital Latch system with Safe Exit Assist. It can detect a vehicle or bicycle approaching from behind and help stop an occupant from opening a door into its path.
On both models, Traffic Jam Assist is available rather than standard, and it requires an active Drive Connect trial or subscription. It monitors surrounding traffic in low-speed conditions on limited-access highways. It can move forward and brake to hold a set following distance, with hands-free steering assistance.
Driver-assistance and advanced safety systems are supplemental aids and are not substitutes for safe and attentive driving. Availability, operation, and effectiveness vary by trim and equipment and depend on factors including road, weather, traffic, and vehicle condition. Always keep your hands on the wheel and your eyes on the road. See your owner’s manual for system limitations and details.
