Choosing between a body-on-frame off-roader and a refined crossover comes down to how you actually plan to drive. The 2026 Lexus GX vs. Mazda CX-90 comparison depends on whether you need a three-row SUV that can tow a boat and climb a fire road, or one built primarily for pavement. If you want to see the GX in person, you can browse our new Lexus GX inventory at Lexus Stevens Creek before reading further.
Both vehicles compete in the midsize three-row SUV space, though only the GX carries a luxury badge, and they take different paths to get there. The GX leans on rugged, truck-based engineering, riding on the same GA-F ladder frame platform as the flagship Lexus LX, while the CX-90 prioritizes on-road refinement and efficiency with a unibody design. That distinction shapes nearly every part of this comparison.
Trim Value: What You Get for Your Money
Trim value is where the GX's engineering priorities become clear. Rather than listing dollar figures, it helps to look at what each trim tier includes standard, since that's where the real comparison happens.
Lexus GX 550 Trim Lineup
The GX 550 comes in six trim grades: Premium, Premium+, Luxury, Luxury+, Overtrail, and Overtrail+. Even the base Premium trim includes Lexus Safety System+ 3.0, a 14-inch touchscreen, and full-time 4WD with a locking center differential. The 21-speaker, 1,800-watt Mark Levinson audio system becomes standard on the Luxury+ trim. Those weighing financing options can get pre-approved online before visiting the showroom.
Mazda CX-90 Trim Lineup
Mazda structures the CX-90 lineup to appeal to a wider price range, with the 3.3 Turbo Select as an accessible entry point and the 3.3 Turbo S Premium Plus at the top. New for 2026, the 3.3 Turbo S Premium Sport trim brings the sportier appearance package to the high-output engine, and Alexa Built-In is now standard across the lineup.
The two SUVs stack up like this on core performance specs:
| Spec | Lexus GX 550 | Mazda CX-90 |
|---|---|---|
| Engine/Powertrain | 3.4L twin-turbo V6 | 3.3L turbo inline-6 with 48V mild hybrid; PHEV available |
| Drivetrain | Full-time 4WD | i-ACTIV AWD |
| Transmission | 10-speed automatic | 8-speed automatic |
| Horsepower/Torque | 349 hp / 479 lb-ft | 280 hp / 332 lb-ft standard; 340 hp / 369 lb-ft on Turbo S with premium fuel |
| Towing Capacity | 9,096 lbs on Overtrail, 9,063 lbs on Premium, Premium+ and Overtrail+, lower on Luxury grades | 3,500 lbs standard; 5,000 lbs with the Towing Package on Premium Sport and above |
| Fuel Economy | 15 city / 21 highway / 17 combined MPG, premium recommended | 23 city / 28 highway / 25 combined MPG on regular fuel |
The 2026 Lexus GX: Rugged Luxury and Proven Capability
The GX rides on the GA-F platform with genuine body-on-frame construction, seating up to seven and sharing its underpinnings with the Toyota Land Cruiser Prado sold globally. That foundation gives the GX a durability profile that unibody crossovers simply can't replicate, and it's a big reason we see so many long-term GX owners return to Lexus Stevens Creek for service rather than trade in early.
Powertrain, Towing, and Off-Road Prowess
Under the hood, the GX 550's twin-turbo V6 produces 349 hp and 479 lb-ft of torque. Towing varies more by grade than most shoppers expect: 9,096 lbs on the Overtrail, 9,063 lbs on Premium, Premium+ and Overtrail+, then 7,844 lbs on Luxury and 7,611 lbs on Luxury+. Confirm the number for the trim you're considering before you plan around it.
Even at the conservative end, that's well beyond the CX-90's 5,000 lb ceiling on Premium Sport and above with the Towing Package. For Bay Area owners, that difference isn't abstract: it means pulling a boat up to Tahoe or hauling a trailer into the Santa Cruz Mountains without thinking twice about the load.
Standard full-time 4WD with a locking center differential comes on every GX 550 trim, and the Overtrail and Overtrail+ grades add serious off-road hardware. You get a locking rear differential and adaptive suspension with E-KDSS, plus a standard 1-inch lift that brings ground clearance to 9.84 inches. Throw in 33-inch all-terrain tires, a front skid plate, and a roof rack, and you've got hardware most crossovers in this class simply don't offer. For drivers who want to escape San Jose traffic for a weekend on unpaved trails near the coast or up in the Sierra foothills, that gap matters.
Edmunds independently tested the GX's 0-60 mph time at 6.7 seconds, slightly behind Lexus's own claimed 6.5 seconds but still respectable for a vehicle built with this much off-road capability in mind.
Premium Interior Comfort and Technology
Inside, the GX pairs NuLuxe leatherette or semi-aniline leather upholstery with heated, ventilated, and massaging front seats depending on trim. The 14-inch touchscreen runs alongside a 12.3-inch digital instrument cluster, and wireless Apple CarPlay and Android Auto come standard across the lineup.
Cargo capacity reaches 76.90 cubic feet in the three-row configuration, or 90.50 cubic feet in the two-row Overtrail setup, giving families and gear-haulers real flexibility. If you want to experience the cabin firsthand, browse our new Lexus GX inventory to schedule a test drive.
The 2026 Mazda CX-90: A Brief Look at Its Distinctive Features
Mazda positions the CX-90 as an upscale alternative without a luxury badge, competing more directly with the Kia Telluride, Toyota Grand Highlander, and Acura MDX than with traditional luxury SUVs. It's a legitimately well-designed vehicle for buyers who prioritize daily drivability and styling over off-road hardware.
Mazda offers a 3.3L turbocharged inline-6 producing up to 280 hp and 332 lb-ft in standard form, with the Turbo S variant pushing output to 340 hp and 369 lb-ft on premium fuel. A CX-90 PHEV variant adds up to 26 miles of electric-only range for drivers who do a lot of short-distance commuting. The CX-90 earned the 2026 IIHS TOP SAFETY PICK+ award along with a 5-Star NHTSA Overall safety rating, both solid marks that speak to its on-road engineering.
Interior Space, Comfort, and Cargo Capacity Compared
Seating capacity is close between the two, with the CX-90 accommodating 7 to 8 passengers depending on configuration and the GX seating up to 7 on Premium, Premium+, Luxury and Luxury+ grades. Cargo splits the decision.
Behind the third row, the CX-90 is the more practical of the two, offering 14.9 cubic feet with the three-person bench and 15.9 cubic feet in configurations with the two-person third row, against the GX's 10.3. Fold everything down and the order reverses: the CX-90 maxes out at 74.2 to 75.2 cubic feet, while the GX reaches 76.9 in three-row form and 90.5 in the two-row Overtrail setup.
If you regularly carry seven people and their bags, the Mazda wins the week. If you're loading camping gear or off-road equipment with the seats down, the GX has more room to work with.
Technology, Safety, and Driver-Assistance Features
Every GX 550 trim comes standard with Lexus Safety System+ 3.0, which includes a Pre-Collision System with Pedestrian Detection, full-speed Dynamic Radar Cruise Control, Lane Departure Alert with Steering Assist, Lane Tracing Assist, Road Sign Assist, Proactive Driving Assist and the Emergency Driving Stop System. Blind Spot Monitor, Rear Cross-Traffic Alert and parking sensors with automatic braking are also standard across the lineup. Traffic Jam Assist is available as well.
Mazda equips every CX-90 with its i-Activsense suite as standard, and its IIHS TOP SAFETY PICK+ rating and 5-Star NHTSA score confirm it performs well in independent crash testing. Both brands take safety seriously, and the difference is at the margins rather than the fundamentals: features like front cross traffic alert, traffic sign recognition and the 360-degree parking sensors arrive on upper CX-90 trims, while the GX includes its equivalents from the base grade. Traffic Jam Assist on the GX requires an active Drive Connect subscription.
Reliability, Warranty, and Ownership Costs
Long-term ownership costs come down to warranty length and how the vehicle is expected to hold up once that coverage runs out.
Lexus GX Warranty Coverage and Predicted Reliability
The GX comes with a 4-year/50,000-mile basic warranty and a 6-year/70,000-mile powertrain warranty, backed by 6-year unlimited-mileage corrosion protection and 4-year roadside assistance. Lexus consistently ranks near the top of reliability studies from J.D. Power and Consumer Reports, a reputation that plays a real role in resale value and peace of mind.
Our certified service team at Lexus Stevens Creek supports GX owners for the long haul, handling everything from routine maintenance to more involved repair work with factory-trained technicians. You can schedule a service appointment online whenever it's convenient.
Mazda CX-90 Warranty Coverage and Predicted Reliability
Mazda backs the CX-90 with a shorter 3-year/36,000-mile basic warranty and 5-year/60,000-mile powertrain warranty, plus 5-year unlimited-mileage corrosion coverage. The PHEV's battery carries separate 8-year/100,000-mile coverage. RepairPal gives the CX-90 a reliability score of 4.0 out of 5, a solid mark, though it comes with shorter coverage windows than the GX offers across the board.
Why the 2026 Lexus GX Comes Out on Top
Line up the 2026 Lexus GX vs. Mazda CX-90 side by side, and two numbers do most of the talking: warranty length and towing capacity. The GX's 6-year/70,000-mile powertrain warranty outlasts the CX-90's 5-year/60,000-mile coverage, and its towing capacity of up to 9,096 lbs nearly doubles the CX-90's ceiling of 5,000 lbs on upper trims equipped with Mazda Genuine Towing Accessories. Add in Edmunds' 7.3/10 rating, standard safety tech across every trim, and a reliability reputation reinforced by J.D. Power and Consumer Reports, and the GX is the more complete vehicle for buyers who want luxury without giving up genuine capability.
