Proven Icon: Lexus GX 460 (2011 -- 2023)
The previous generation GX 460 represents the classic Lexus formula, earning its reputation as a bulletproof, go-anywhere luxury machine.
-
Legendary V8 Engine: Under the hood of the most recent GX 460 is the iconic 4.6L V8 engine, delivering 301 horsepower and 329 lb-ft of torque. While less powerful than the new twin-turbo V6, this naturally aspirated V8 is renowned for its effortless smoothness, distinctive exhaust note, and proven long-term reliability.

-
Exceptional Value: A Certified Pre-Owned GX 460 offers an incredible entry point into a full-frame, luxury SUV with the full backing of the Lexus CPO warranty.
Key Strengths of the Certified Preowned GX 460
-
Dedicated Off-Road Trims: The introduction of the Overtrail and Overtrail+ trims brings factory-equipped off-road capability, including available Electronic Kinetic
-
Dynamic Suspension System and electronic locking rear differential: The GX 550 has more tools for off-roading. For the GX 460, modifications were often needed to achieve this level of performance.
-
Rear Liftgate: The GX 460 has a side-swing rear door while the GX 550 adopts a modern power liftgate with a lift-up glass hatch—a convenience upgrade many drivers in Phoenix will appreciate.

Wider Stance: The GX 550 is nearly four inches wider than the outgoing GX 460, giving it a more planted, modern look and improved stability on and off the pavement.
New King: 2026 Lexus GX 550
The 2026 GX 550 is an entirely new machine, built from the ground up to revolutionize the segment. It maintains the body-on-frame toughness of its predecessor but updates virtually every aspect for the modern era.
GX 550: The Generational Leap
The differences between the two models are substantial, highlighting the massive leaps in performance, technology, and capability.
1. Performance and Power: Turbocharged Dominance
The biggest change lies in the engine bay. GX 550 models have a 3.4L twin turbo V6 that generates 349 horsepower. That’s an extra 48 horsepower compared to the naturally aspirated V8 that powers the GX 460. The torque rate jumps by 150 lb-ft to 479 lb-ft of torque when you choose the newest edition.
GX 460 models have six speed automatic transmissions while the new GX 500 models have a 10-speed direct shift automatic. Four additional gears help the GX 500 driver harness extra horsepower and torque. It ensures quicker, smoother shifting, enhancing the Lexus driving experience.
In fact, the GX 550 delivers 45% more torque at significantly lower RPMs, providing immediate, authoritative power that the GX 460 simply cannot match. This increase in capability and power results in a higher towing capacity. The GX 460 can pull up to 6,500 lbs. However, the 2026 GX 550 can claim a class-leading tow rating of 9,063 lbs.
2. Design and Capability: Rugged Sophistication
The GX 550 features a boxy, muscular design that proudly asserts its off-road DNA, combined with features that enhance its dual-purpose nature.
3. Technology and Comfort: A Giant Leap
Interior technology represents another distinction between the two generations. Later models of the GX 460 could boast a 10.3-in touchscreen. Yet the GX 550 dashboard has much bigger bragging rights. Drivers will appreciate the pairing of a 14-in touchscreen and a 12.3-in digital display.
With Lexus Safety System+ 2.5, late model GX460 models have plenty of driver assistance technology. However, the 2026 GX 550 is equipped with the ultramodern Lexus Safety System 3.0.
Furthermore, you can get more luxuries on the GX 550 than the well-equipped GX 460. For instance, you can get heated and ventilated front seats on certain GX 460 models. Those same seats in the GX 550 can also have a massage capability.
