What’s new for 2026?

The 2026 GX 550 carries over with no major changes. It’s still got its strong 3.4-liter twin-turbo V6 engine making 349 hp and 479 lb-ft, and gets a predictably lousy 15 city/21 highway/17 combined mpg. It starts around $66,935 including destination, with upper trims reaching the low-$80,000s before options.

What’s it look like?

Visually, the GX 550 looks terrific. It is blocky, upright and unapologetic, with a squared-off nose, high beltline and tough stance, yet it does not appear elephantine The design feels modern without being precious. It has presence without screaming for attention.

Inside, the GX is roomy, functional and properly upscale, though not always as plush as some buyers may expect from the badge. The dashboard is cleanly horizontal, the driving position is excellent, and the available third row gives it true family-hauling ability, rather than “the dog will fit back there.”

Heated and ventilated front seats, a large center screen, available captain’s chairs and available higher-end audio help keep it in the Lexus luxe category.

Tech is centered around a 14-inch touchscreen, a 12.3-inch digital instrument display, wireless Apple CarPlay and Android Auto, available wireless charging and a strong standard safety suite. Lexus Safety System 3.0+ brings adaptive cruise control, lane-centering, road-sign recognition, automatic emergency braking and other electronic watchdogs.

How’s the drive?

On the road, the GX feels powerful, sturdy and confident - but not especially sporty. The twin-turbo V6 has plenty of low-end torque, the steering is steady, and the ride has that big-rig composure. You won’t be compelled to race anyone, or to gun it. It’s happiest covering distance, climbing grades, handling bad roads and making potholes feel invisible.

Room for improvement

Fuel economy is undeniably poor, the vehicle feels heavy and the fanciest off-road hardware is tied to upper trims, so get ready to pony up.

Conclusion: the best thing about the GX 550 is that it knows what it is - what you see is what you get. A lot of modern SUVs try to be everything at once - sports sedan, lounge, tech pod, school bus and weekend warrior. The GX feels expensive, capable and substantial, with enough refinement for daily driving but enough mechanical seriousness to suggest it would not panic at mud, snow, rocks or a badly maintained road.
