The 2026 Mazda CX-90 3.3 Turbo produces 280 horsepower and 332 lb-ft of torque on regular 87-octane fuel. Its 48-volt M-Hybrid Boost system assists low-speed throttle response without requiring external charging. The 2026 Toyota Grand Highlander gasoline engine is a 2.4-liter turbocharged four-cylinder producing 265 horsepower. Both pair their gasoline engines with eight-speed automatic transmissions; Mazda supplies the stronger standard horsepower figure.
The CX-90 Turbo S raises output to 340 horsepower and 369 lb-ft with recommended 91-octane premium fuel. The Grand Highlander Hybrid MAX delivers 362 combined horsepower and 400 lb-ft through a six-speed automatic. Toyota wins that peak-output comparison. We favor Mazda’s inline-six configuration for customers who want substantial power within a chassis engineered around driving precision.
AWD, Handling, and Towing Capability
Every 2026 Mazda CX-90 includes rear-biased i-Activ AWD. Double-wishbone front suspension, multilink rear suspension, and Kinematic Posture Control work together to manage cornering behavior and suppress body lift. The 2026 Toyota Grand Highlander offers AWD on gasoline and conventional hybrid versions, while Hybrid MAX includes it as standard. We value Mazda’s consistent AWD availability across the lineup, particularly for Missouri’s changeable weather.
Select CX-90 inline-six trims can tow up to 5,000 pounds with the required Mazda Genuine hitch and available Towing mode; other versions are rated at 3,500 pounds. The Grand Highlander gasoline and Hybrid MAX models also reach 5,000 pounds when properly equipped, versus 3,500 pounds for conventional hybrids. Mazda combines comparable maximum towing capability with its distinctive chassis hardware.
Interior Comfort and Cargo Space
The 2026 Mazda CX-90 inline-six lineup accommodates seven or eight occupants, depending on configuration. Available Nappa leather and ventilated second-row captain’s chairs lend the cabin a more tailored atmosphere. The 2026 Toyota Grand Highlander also seats up to eight, with available leather upholstery and ventilated second-row seating. We prefer Mazda’s restrained presentation and material choices for families who appreciate tactile detail.
With both rear rows folded, the CX-90 inline-six provides up to 74.2 cubic feet of cargo space, compared with 97.5 cubic feet in the Grand Highlander. Toyota has the clear advantage in maximum load volume. Mazda’s appeal rests elsewhere: flexible seating, available panoramic glazing, and a cabin whose appointments make everyday journeys feel more considered.
Infotainment and Driver Assistance
The 2026 Mazda CX-90 adds standard Alexa voice commands, while Turbo Preferred and higher trims provide a 12.3-inch display with wireless Apple CarPlay and Android Auto. The 2026 Toyota Grand Highlander supplies a 12.3-inch touchscreen and wireless smartphone integration as standard. Available audio systems differ: Mazda offers 12-speaker Bose sound, while Toyota offers an 11-speaker JBL system.
Standard CX-90 assistance includes Smart Brake Support, Blind Spot Monitoring, and Lane-keep Assist. The Grand Highlander features Toyota Safety Sense 3.0, plus standard blind-spot monitoring and rear cross-traffic alerts. Mazda’s available 360° View Monitor with See-Through View reveals areas normally obstructed by the vehicle’s body during low-speed maneuvering. We appreciate that practical aid when positioning a three-row SUV in confined parking spaces.
Electrification and Our Recommendation
The 2026 Mazda CX-90 inline-six achieves an EPA-estimated 25 mpg combined with standard AWD. The 2026 Toyota Grand Highlander Hybrid offers up to a manufacturer-estimated 36 mpg combined, depending on configuration. Mazda also offers the CX-90 PHEV: 323 horsepower with recommended premium fuel and an EPA-estimated 26-mile electric range on a full charge. Toyota’s Grand Highlander hybrids do not accept external charging.
For drivers comparing the CX-90 and Grand Highlander near St. Louis, we recommend Mazda when cabin craftsmanship, standard AWD, and chassis sophistication lead the decision. Toyota’s larger cargo hold deserves consideration, but Mazda brings the more compelling combination for our driving-focused customers. At Bommarito Mazda West County, we can help match seating arrangements, powertrain preferences, and towing requirements to the appropriate CX-90 configuration.
