It’s astonishing to think that the Lexus GX hasn’t undergone a redesign since 2009. The tough body-on-frame SUV has received some changes in appearance over the years, but now, after 15 years, Lexus has finally unveiled a brand-new GX, now known as the GX 550.
While unibody SUVs have become the standard, the 2024 Lexus GX 550 remains true to its origins and purpose with its body-on-frame platform. The GX has always been the luxurious off-roader in the Lexus lineup, and now it boasts a design that complements its off-road capabilities. The GX now sports a more rugged SUV aesthetic compared to the previous generation. Lexus states that with the arrival of the unibody three-row TX crossover, the GX can now focus more on its rugged nature without prioritizing the desires of families seeking a smooth-riding midsize SUV.
Externally, the GX 550 features a more angular appearance than its predecessor. One interesting design element is the hood creases, which serve to indicate the position of the front wheels, making it slightly easier when navigating obstacles during off-road adventures.
The 2024 GX is an entirely new vehicle built from the ground up and is constructed on the new GA-F platform, which is the same body-on-frame platform utilized by the Lexus LX 600, as well as the Toyota Sequoia, Tundra, Tacoma, and even the new Land Cruiser. Speaking of the Land Cruiser, it’s evident that the GX shares many similarities with the 2024 Land Cruiser.
The previous GX 460 was equipped with an outdated V8 engine producing only 301 horsepower and 329 pound-feet of torque, paired with a six-speed automatic transmission. The GX 550, on the other hand, boasts a more modern 3.4-liter twin-turbo V6 engine that generates more power than the old V8, with 349 hp and 479 lb-ft of torque. The GX 550 now features a 10-speed automatic transmission and can tow over 9,000 pounds, compared to the previous GX’s 6,500-pound towing capacity. It’s also more fuel-efficient, with a rating of 15 mpg in the city, 21 mpg on the highway, and 17 mpg combined. Lexus has confirmed that a hybrid version of the GX is in the works for those seeking even greater fuel efficiency, although no official timing has been announced.
The new V6 engine injects a considerable amount of power into the GX, finally giving it some liveliness. Turbo lag is minimal, and the electric power steering provides more feedback than before. The overall powertrain feels significantly more modern than the outgoing GX. The main distinction between the GX 550 and the new Land Cruiser is that the Land Cruiser is equipped with a turbocharged four-cylinder hybrid powertrain, whereas the Lexus features a V6 engine.
As a true off-roader, the GX comes standard with full-time 4WD and a limited-slip locking center differential. The more rugged Overtail and Overtail+ trim levels are equipped with a locking rear differential, which evenly distributes torque between the rear wheels. Switching between the 4Hi and 4Lo modes is now quicker than before, although the transmission still needs to be put in neutral when doing so.
The GX offers a convenient 360-degree camera system that provides a view of what’s happening underneath the vehicle or a split view for a better look at the road ahead.
The Overtrail models enhance the GX’s off-road capabilities with a standard Electronic Kinetic Dynamic Suspension System (E-KDSS). This system can automatically engage and disengage the front and rear stabilizer bars when more wheel articulation is required. To showcase the GX’s capabilities, Lexus has created an off-road obstacle course to demonstrate how well the GX performs on trails. The GX effortlessly conquers uneven terrain while still providing a comfortable cabin experience.
Speaking of the cabin, the interior of the GX 550 resembles that of other Lexus models, but its dashboard features a horizontal top to improve visibility of the road ahead. The center of the dashboard houses a 14-inch touchscreen, while a 12.3-inch digital gauge cluster sits in front of the driver. A head-up display is available as an option. The infotainment system is familiar, as it is also utilized in other Lexus and Toyota models. The good news is that the GX incorporates physical dials for frequently used controls, such as air conditioning and audio volume.
The overall look and feel of the interior may not be as exciting as the exterior. This is especially true if you opt for the full black interior, which can appear a bit dull. Fortunately, there are appealing two-tone options available. A panoramic sunroof adds some brightness to the cabin, while a standard-sized moonroof is included.
The GX still offers three rows of seats on select trim levels, with the second row configurable as either a bench seat or captain’s chairs. The Overtrail models only provide two rows of seats. The third row is somewhat cramped, so if you require more space in the back, the TX may be a better option.
The pricing for the 2024 GX 550 starts at $65,600 for the base Premium trim level, with the Luxury+ trim level being the most expensive, starting at $82,600. The Overtrail version begins at $70,600.
When comparing it to its biggest rival, the Land Rover Defender, the GX 550’s starting price of $65,600 is higher than the Defender’s $62,075 for the four-door version with a four-cylinder engine.
Lexus anticipates selling 33,000 GX 550 SUVs this year, a number similar to its 2023 sales figures. This low number is likely due to production limitations rather than actual demand, as the response to the new GX has been overwhelmingly positive. Ultimately, the 2024 Lexus GX 550 distinguishes itself in the competitive midsize luxury SUV segment with its rugged exterior and unparalleled capabilities. It’s a vehicle that we wouldn’t mind seeing parked in our driveway someday, particularly in the Nori Green GX 550 Overtrail+ variant.
