2026 Lexus GX: Specs, Towing & Features
The 2026 Lexus GX occupies an interesting place in the luxury SUV market. It offers the upscale cabin, technology, and comfort shoppers expect from Lexus, but underneath that luxury is a body-on-frame SUV designed for serious towing and off-road capability.
For 2026, the GX continues with six grades: Premium, Premium+, Luxury, Luxury+, Overtrail, and Overtrail+. Every model uses a 3.4-liter twin-turbocharged V6 producing 349 horsepower and 479 lb-ft of torque, paired with a 10-speed Direct Shift automatic transmission and full-time four-wheel drive.
The result is an SUV that can handle everyday Southern California driving, family road trips, towing, and considerably more demanding terrain when properly equipped.
If you are researching the 2026 Lexus GX, comparing 2026 Lexus GX specs, or wondering how much the 2026 Lexus GX costs, here is what you should know before shopping.
2026 Lexus GX Specs
One of the biggest strengths of the GX is that Lexus does not reserve its core powertrain for higher trims.
Every 2026 GX 550 receives the same twin-turbocharged engine.
3.4-Liter Twin-Turbo V6
The 3.4-liter twin-turbo V6 produces 349 horsepower and 479 lb-ft of torque.
That torque figure is especially important for an SUV designed around towing and off-road use. The engine delivers the low-end pulling strength needed for trailers while also providing responsive acceleration during everyday driving.
Power is managed through a 10-speed Direct Shift automatic transmission.
Standard Full-Time 4WD
Full-time four-wheel drive is standard across the entire GX lineup.
A Torsen limited slip locking center differential is also standard and can distribute power between the front and rear axles to improve control when traction becomes limited.
That means even the Premium trim receives genuine four-wheel-drive capability rather than requiring buyers to select an expensive off-road package just to get it.
2026 Lexus GX Fuel Economy
The GX is built around capability rather than maximizing fuel economy.
The GX delivers up to an EPA estimated 15 city MPG, 21 highway MPG, and 17 combined MPG.
For shoppers, that efficiency should be viewed alongside the GX's 349-horsepower twin-turbo engine, full-time four-wheel drive, body-on-frame construction, and substantial towing capability.
2026 Lexus GX Towing Capacity
The 2026 Lexus GX towing capacity is one of the SUV's standout specifications.
When properly equipped, the GX can tow up to 9,096 pounds.
That maximum rating belongs to the GX 550 Overtrail. Lexus rates the Overtrail+ at up to 9,063 pounds.
The Premium and Premium+ also provide substantial towing capability, with Lexus listing up to 9,063 pounds for the Premium and Premium+ in its current 2026 product information.
Towing capacity varies by configuration, so buyers planning to tow should always confirm the rating of the exact GX they are considering.
What Can You Tow with a Lexus GX?
A maximum available towing capacity above 9,000 pounds opens the door to a wide range of recreational equipment.
Depending on the weight and configuration, that could potentially include:
- Travel trailers
- Boats
- Utility trailers
- ATVs and side-by-sides
- Personal watercraft
- Camping equipment
- Small equipment trailers
Trailer weight is only one part of safe towing. Passengers, cargo, tongue weight, accessories, and the configuration of the vehicle can affect available capacity.
The standard tow hitch receiver also means towing capability is integrated into the GX's design rather than feeling like an afterthought.

2026 Lexus GX Trims
The six available GX grades can essentially be divided into three groups.
Premium models focus on value and everyday luxury. Luxury models add more upscale appointments. Overtrail models emphasize off-road capability.
GX 550 Premium
Key Perks
Full GX Performance
The Premium uses the same 349-horsepower, 479-lb-ft twin-turbo V6 found throughout the lineup.
Standard Full-Time 4WD
Full-time 4WD and the Torsen limited slip locking center differential give the entry GX legitimate capability from the start.
Seven-Passenger Capability
Premium models can accommodate up to seven passengers, making the GX useful as both an adventure vehicle and family SUV.
Strong Towing Capacity
With towing capability reaching up to 9,063 pounds when properly equipped, the Premium does not require a higher trim simply to unlock serious towing capability.
Ontario Auto Center | Lexus GX 550 Premium
GX 550 Premium+
The Premium+ builds on the standard model with additional comfort and convenience equipment.
It is an appealing middle ground for shoppers who want more interior amenities without moving into the Luxury grades.
Premium+ buyers can also choose between second-row captain's chairs and a 60/40 split-folding bench, allowing the interior to be configured around passenger needs.
For families, that flexibility can make a noticeable difference when deciding between easier second-row access and maximum seating capacity.

GX 550 Luxury
The Luxury shifts the GX toward a more premium road-focused experience.
It retains the same twin-turbocharged engine and four-wheel-drive system while adding upscale interior and exterior appointments.
Lexus equips the Luxury grades with 22-inch forged alloy wheels, creating a noticeably different appearance from the rugged 18-inch wheels used on Overtrail models.
For shoppers who expect to spend considerably more time on pavement than trails, the Luxury provides the rugged foundation of the GX with a more upscale personality.
GX 550 Luxury+
Luxury+ moves toward the top of the traditional GX lineup.
This trim is aimed at buyers who want a highly equipped luxury SUV but do not need the specialized off-road equipment of an Overtrail.
Like the Premium+, it can be configured with second-row captain's chairs or a split-folding bench.
Luxury and Luxury+ models remain capable SUVs, but buyers prioritizing maximum towing or off-road performance should pay close attention to configuration. Their towing ratings are lower than the highest-rated Premium and Overtrail models.

GX 550 Overtrail
This is where the personality of the 2026 Lexus GX changes dramatically.
The Overtrail is designed specifically for drivers who intend to use the GX beyond paved roads.
Key Perks
Up to 9,096 Pounds of Towing Capacity
The Overtrail provides the highest maximum towing capacity in the 2026 GX lineup when properly equipped.
Electronic Locking Rear Differential
In addition to the standard Torsen center differential, Overtrail models add an electronically controlled locking rear differential.
That can help distribute power evenly between the rear wheels when navigating low-traction terrain.
Electronic Kinetic Dynamic Suspension System
E-KDSS is standard on Overtrail and Overtrail+ models.
The system can independently lock or unlock the front and rear stabilizer bars depending on conditions, helping balance wheel articulation off-road with stability on pavement.
Additional Ground Clearance
A one-inch suspension lift comes standard on the Overtrail and Overtrail+, increasing minimum running ground clearance to 9.84 inches.
18-Inch Wheels
Instead of oversized luxury wheels, the Overtrail uses 18-inch alloy wheels designed around its more rugged mission.
Ontario Auto Center | Lexus GX Overtrail
GX 550 Overtrail+
The Overtrail+ combines the specialized capability of the Overtrail with additional luxury and convenience.
It retains E-KDSS, the electronically locking rear differential, increased ground clearance, and serious towing capability while creating a more premium environment.
For 2026, Lexus also makes prewired auxiliary switches and an onboard air compressor standard on both Overtrail models.
That onboard compressor can be particularly useful for drivers who adjust tire pressures for different terrain and then need to reinflate their tires before returning to highway driving.

2026 Lexus GX Off-Road Features
The 2026 Lexus GX features go well beyond standard four-wheel drive.
Multi-Terrain Select
Multi-Terrain Select adjusts vehicle systems based on the surface underneath the GX.
In low-range four-wheel drive, available settings include Auto, Sand, Mud, and Rock. In high range, drivers can choose among Auto, Dirt, Sand, Mud, and Deep Snow.
Crawl Control
Crawl Control can manage engine output and braking pressure at one of five driver-selected low-speed settings.
This allows the driver to focus more attention on steering and choosing a path through difficult terrain.
Multi-Terrain Monitor
Four cameras provide views around and underneath the vehicle through the 14-inch center display.
When navigating rocks, narrow trails, or uneven terrain, the ability to see obstacles that would normally be hidden from the driver's seat can be extremely useful.
Overtrail Angles
Lexus lists approach, breakover, and departure angles of up to 26 degrees, 24 degrees, and 21 degrees across the GX lineup depending on configuration.
The Overtrail's additional suspension lift further supports its off-road-focused design.
2026 Lexus GX Interior
Capability is only half of the GX's personality.
Inside, Lexus has designed the SUV to feel much more like a modern luxury vehicle than a traditional rugged off-roader.
Seating for Up to Seven
Premium, Premium+, Luxury, and Luxury+ grades offer seating for up to seven.
Depending on grade, buyers can choose second-row captain's chairs or a 60/40 split-folding bench.
Overtrail models seat five because their configuration prioritizes cargo flexibility and off-road use rather than third-row passenger capacity.
Heated and Ventilated Front Seats
Heated and ventilated front seats are standard, providing additional comfort during both hot Inland Empire summers and colder winter mornings.
Practical Cargo Features
The GX includes two additional storage areas underneath the cargo floor for smaller items.
Lexus also equips the SUV with a 120-volt AC inverter, making it easier to power compatible equipment during camping trips, tailgating, or outdoor activities.
2026 Lexus GX Technology
The 2026 GX combines its rugged hardware with a modern technology package.
14-Inch Lexus Interface Touchscreen
A 14-inch high-definition touchscreen is standard.
The large display serves as the primary interface for navigation, entertainment, vehicle functions, and compatible connected services.
Wireless Smartphone Integration
Wireless Apple CarPlay and Android Auto compatibility are standard.
A digital 12.3-inch Multi-Information Display also places vehicle information directly in front of the driver.
Available Head-Up Display
An available Head-Up Display can project information such as speed, navigation directions, and selected driver-assistance information into the driver's field of view.
Available Mark Levinson Audio
Audiophiles can choose an available 21-speaker Mark Levinson Premium Surround Sound system specifically tuned for the GX cabin.
Available Digital Key
An available Digital Key can allow a compatible smartphone to function as a vehicle key and can be shared with additional registered users through the Lexus app.
Lexus Safety System+ 3.0
Every 2026 GX comes standard with Lexus Safety System+ 3.0.
The suite includes technologies such as:
- Pre-Collision System with Pedestrian Detection
- Full-Speed Dynamic Radar Cruise Control
- Lane Tracing Assist
- Lane Departure Alert with Steering Assist
- Road Sign Assist
- Proactive Driving Assist
- Emergency Driving Stop System
These systems are designed to assist an attentive driver rather than replace driver awareness.
For Southern California drivers dealing with long freeway commutes and changing traffic conditions, the standard driver-assistance suite adds another layer of everyday usefulness to the GX.

Which 2026 Lexus GX Should You Buy?
Choosing the right GX depends on how you intend to use it.
Choose the GX Premium for Overall Value
The Premium already provides the 349-horsepower twin-turbo V6, full-time 4WD, seven-passenger capability, a 14-inch touchscreen, and up to 9,063 pounds of towing capacity when properly equipped.
For many buyers, that is already an impressive combination.
Choose the GX Premium+ for More Everyday Comfort
The Premium+ makes sense for families and daily drivers who want additional amenities and greater seating flexibility without moving into the more expensive Luxury range.
Choose the GX Luxury or Luxury+ for Premium Comfort
These models make the most sense for buyers who want the GX's rugged body-on-frame foundation but expect most of their driving to happen on pavement.
Choose the GX Overtrail for Off-Road Capability
For buyers planning regular trips into the mountains, desert, trails, or remote camping areas, the Overtrail is the standout.
The suspension lift, E-KDSS, locking rear differential, 18-inch wheels, specialized terrain systems, and 9,096-pound maximum towing capacity give it a clear purpose.
Choose the GX Overtrail+ for Capability and Luxury
The Overtrail+ is the choice for shoppers who want serious off-road hardware without sacrificing as many premium amenities.
Is the 2026 Lexus GX a Good Fit for Southern California?
The GX is particularly interesting in Southern California because it can handle several very different lifestyles.
During the week, it offers the comfort, technology, and driver-assistance features expected from a luxury SUV.
On weekends, its towing capability can accommodate recreational equipment, while its four-wheel-drive and Overtrail hardware open opportunities for camping and off-road destinations throughout California.
Families can choose seven-passenger configurations, while buyers more focused on adventure can select a five-passenger Overtrail.
That versatility is ultimately one of the GX's biggest strengths.
