Compare the2025 Mazda CX-90VS 2025 Infiniti QX80

The CX-90 Premium has a standard Secondary Collision Reduction System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The QX80 doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the CX-90. But it costs extra on the QX80.

When descending a steep, off-road slope, the CX-90’s standard Hill Descent Control allows you to creep down safely. The QX80 doesn’t offer Hill Descent Control.

Both the CX-90 and QX80 have Rear Cross Traffic Alert, but the CX-90 Premium Plus/Turbo S has Rear Cross Traffic Braking (automatically applies the brakes) to better prevent a collision when backing near traffic. The QX80’s Rear Cross Traffic Alert doesn’t automatically brake.

For better protection of the passenger compartment, the CX-90 uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The QX80 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the CX-90 and the QX80 have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors and available around view monitors.

The Mazda CX-90 has achieved the Insurance Institute for Highway Safety’s (IIHS) highest rating of “Top Safety Pick Plus” for the 2024 model year. This distinction is based on its exceptional performance in IIHS’ rigorous battery of safety tests. Specifically, it earned a “Good” rating in the latest, more stringent moderate overlap front crash test, a “Good” result in the updated side impact test, and a “Good” score in the revised pedestrian crash prevention test. The QX80 has not yet been evaluated by the IIHS for 2024.

There are almost 3 times as many Mazda dealers as there are Infiniti dealers, which makes it much easier should you ever need service under the CX-90’s warranty.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Mazda vehicles are more reliable than Infiniti vehicles. J.D. Power ranks Mazda above average in long-term dependability. With 5 more problems per 100 vehicles in the first three years of ownership, Infiniti is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Mazda vehicles are more reliable than Infiniti vehicles. Consumer Reports ranks Mazda 6 places higher in reliability than Infiniti.

On the EPA test cycle the CX-90 running its gasoline engine gets better mileage than the QX80:

The CX-90 PHEV can travel with zero emissions for 26 miles. The QX80 can’t move without running its internal combustion engine.

Regenerative brakes improve the CX-90’s fuel efficiency by converting inertia back into energy instead of wasting it. The QX80 doesn’t offer a regenerative braking system.

To lower fuel costs and make buying fuel easier, the Mazda CX-90 uses regular unleaded gasoline (premium recommended on CX-90 PHEV for maximum performance). The QX80 requires premium, which can cost on average about 84.9 cents more per gallon.

The CX-90 has a standard locking fuel door and a locking charge port which lock and unlock with the power locks. The QX80 doesn’t offer a locking fuel filler door. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank and a locking charge port prevents tampering and damage.

The CX-90’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the QX80’s standard 60 series tires. The CX-90 Premium/Turbo S’ tires have a lower 45 series profile than the QX80 Luxe/Sensory/Autograph’s 50 series tires.

For a smoother ride and more stable handling, the CX-90’s wheelbase is 1.8 inches longer than on the QX80 (122.8 inches vs. 121 inches).

The Mazda CX-90 may be more efficient, handle and accelerate better because it weighs about 850 to 1250 pounds less than the Infiniti QX80.

The CX-90 is 10.4 inches shorter than the QX80, making the CX-90 easier to handle, maneuver and park in tight spaces.

The CX-90 is 8.4 inches shorter in height than the QX80, making the CX-90 much easier to wash and garage and drive (lower center of gravity).

Unibody construction lowers the CX-90’s center of gravity significantly without reducing ground clearance. This contributes to better on the road handling and better off-road performance and stability. In addition, unibody construction makes the chassis stiffer, improving handling and reducing squeaks and rattles. The QX80 doesn’t use unibody construction, but a body-on-frame design.

The CX-90 has .6 inches more front headroom, 1.5 inches more rear headroom, .2 inches more rear legroom and .7 inches more third row headroom than the QX80.

To help drivers see further while navigating curves, the CX-90 Turbo S has standard adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The QX80 doesn’t offer cornering lights.

The Mazda CX-90 outsold the Infiniti QX80 by over two to one during 2023.
