These two brands are known for quality and creature comforts in every model they release, making the comparison of the 2025 INFINITI QX80 and the Lexus GX a perfect choice.

Who Packs The Most Power Into Their Luxury SUV?
When you look at the engine size in these SUVs, it is a little surprising to discover that the INFINITI QX80 uses a 3.5L V6 Turbo while the Lexus GX has a 3.4L V6 Turbo. The size difference is minimal, but INFINITI manages to coax over 100 more horsepower from that slightly larger engine to deliver a whopping 450 horses compared to the 349 HP delivered by Lexus in the GX. The significantly greater power in the INFINITI QX80 means it easily handles the added vehicle weight of about 600 pounds over the GX and has a payload capacity of an added 350 pounds over the limit of the Lexus.
Equally as impressive is that you can enjoy all that raw power and still see 16 MPG in the city and 20MPG on the highway when tooling around in the QX80. The less powerful GX should rule the fuel economy with the smaller power plant and fewer horsepower. Still, they are losing the battle in the city with only 15MOG and a somewhat dismal win on the highway with only a single added mile per gallon over the INFINITI QX80.
The final straw in this performance comparison is the warranty each manufacturer will provide buyers. While both allow a four-year warranty, INFINITI caps the mileage at 60K to allow you a great deal of driving pleasure while still within the limits of the full warranty. On the other hand, Lexus only allows 50K miles before it yanks the complete warranty and forces consumers to pay for the needed repairs.
Added Bells And Whistles
When you enter the realm of luxury SUVs, there is an abundance of gadgets and gizmos that make driving relaxing and fun. The majority of the top-end features that come standard on these vehicles are not even options for most daily drivers. But there are a few that the INFINITI QX80 includes as standard equipment that the Lexus GX is missing, such as rain-sensing wipers, a panoramic moonroof, and a hands-free motion-activated liftgate.
While all vehicles must conform to certain safety standards, the luxury models tend to go above and beyond in this area. These two large SUVs are very similar in their safety and suspension offerings, with only a few variations. The INFINITI QX80 includes an around-view camera that can provide that extra set of eyes needed for maneuvering in tight spaces. While the ride depends on quality suspension, it can also be seen as a safety feature that automatically smooths the bumpy feel of older roads or, when off-road, adds to the vehicle’s stability. The inclusion of the air suspension and all-weather tires as standard features puts the QX80 just ahead of the Lexus GX, yet again.
Cavernous Capacity, Or Not?
If you are shopping for a full-size SUV, then it is a good bet that size matters to you, in which case, the QX80 is the winner by far. While both vehicles seat seven, the INFINITI QX80 can accommodate an added 22 cubic feet of cargo with those passengers. In comparison, the GX will only carry 10.3 cubic feet of gear or personal items. When you fold down the second row of seats, that capacity jumps to over 100 cubic feet in the INFINITI, while the Lexus can only manage a bit over 76 cubic feet.
Looking at the overall size of these SUVs from the exterior, the INFINITI QX80 is just over five inches wider. The benefit of that few inches can be more appreciated when you realize it adds to the hip and shoulder room for all the passengers. When evaluating the height, the overall size is within an inch from the INFINITI QX80 to the Lexus GX, which makes the headroom a dead heat, showing a fraction of an inch difference. The final comparison is one that is shocking and critical to the stability and safety of these massive SUVs. The wheelbase for the GX is just over 112 inches, while the INFINITI QX80 is just over 121 inches. That added foot adds to the handling, safety, and functionality when taking the QX80 off-road or when navigating any roadway that is not perfectly even or level.
In the end, the cost of the INFINITI QX80 is higher than the Lexus GX, but the added features and capability easily justify the price. You are getting an SUV that is filled with technology, comfort features, and safety that is very well equipped and ready to head off-road, should that be your desire or need. The Question for buyers is, do they want the appearance of a sport utility vehicle that is easy to drive and includes all the creature comforts, or do they want all of that as well as one that is more rugged and ready to take on the less glamour side of the average SUV’s life? Since the birth of this brand, INFINITI has been setting the bar higher and higher in each vehicle class, and the QX80 is no exception.
