Tackling the road in style is possible in both SUVs, but the new INFINITI QX80 works harder for you. Available in either 2WD or 4WD drivetrains, the QX80 powers down the road with the help of a 450-horsepower 3.5-liter V-6 twin-turbo engine, getting you up to speed with 516 pound-feet of torque. This strength pairs with a nine-speed automatic transmission and lets you pull up to 8,500 pounds when properly equipped.
The Lexus powertrain is still potent but outclassed. It has a 3.4-liter V-6 twin-turbo engine that produces only 349 horsepower and 479 pound-feet of torque, coupled to a 10-speed automatic transmission. The towing specs are less certain on the Lexus GX: Some versions, like the Overtrail, offer a 9,096-pound towing limit,2 while the Luxury+ trim has a less impressive 7,601-pound capacity.2
INFINITI QX80 vs. Lexus GX Design
What kind of SUV are these engines pulling? The Lexus GX prefers to be seen as rugged and durable. Its blocky, almost appliance-like exterior is businesslike and straightforward. It meshes well with darker colors to make a promising exterior.
The INFINITI QX80 feels like the next step in that design process. A square and businesslike exterior is evident, but the front is more curved, with headlights turning upwards. Instead of a rigid and organized vehicle, this more aerodynamic shape adds to its personality, with a grill that molds upwards into an expressive chassis. It feels more modern and prestigious when side by side with the Lexus GX.

That outdoorsy, blocky look of the Lexus GX does feature more maneuverable stats, but at a cost. The Lexus GX is more than a foot shorter than the INFINITI QX80, giving it more space to drive. However, if you want your family to be comfortable while storing gear – with plenty of room to spare – the QX80 provides a much better experience. You'll get more than two inches of extra front and second-row legroom, nearly 12 more cubic feet of trunk space, and over 24 cubic feet of additional maximum cargo volume when comparing three-row iterations.
Look at INFINITI QX80 vs. Lexus GX seating, and you'll see that the INFINITI SUV lets you seat seven passengers on any trim and eight seats with the Split-Bench Seat Package. The Lexus has seven seats by default. However, the rough-terrain Overtrail and Overtrail+ trims lose the third row – and still only get 90.5 cubic feet of maximum cargo capacity.
Lexus GX vs. INFINITI QX80 Interior
Compare INFINITI QX80 and Lexus GX cabins further – you'll see how close the feature matchup is. The Lexus model sports a 14-inch touchscreen for your infotainment. The Luxury and Luxury+ variants are the only GX models without their NuLuxe synthetic leather seating trim, limiting your options if you want an authentic leather interior. The Lexus Safety System+ 3.0 offers a swathe of safety systems, such as Lane Departure Alert and Lane Tracing Assist, that nudge you in the right direction.
What's on the inside of the more robust model? In your QX80, you'll be welcomed into synthetic leather, leather, or quilted semi-aniline leather, depending on the trim type. Standard on all QX80 levels is a 14.3-inch infotainment console, allowing easy access to Bluetooth® services and Amazon Alexa® Built-In. Safety won't be a concern with standard INFINITI ProPILOT Assist 1.1, which includes Active Lane Keep Assist, Driver Attention Alert, and much more to keep you centered in your lane while cruising down the freeway, alerting you if your attention drifts.
