2020 Lexus GX (J150, facelift 2019) Dimensions, Size & Specs

The 2020 Lexus GX has a curb weight of 2327 kg (5130 lbs). This relatively heavy weight contributes to a stable and solid driving feel, enhances ride comfort, and improves off-road traction. However, it may slightly impact fuel efficiency and acceleration compared to lighter SUVs, as more power is needed to move the vehicle.

The 2020 Lexus GX offers a ride height or ground clearance of 206 mm (8.1 inches). This robust ground clearance is excellent for off-road driving, allowing the SUV to navigate uneven terrain, rocks, and other obstacles with minimal risk of underbody damage. It strikes a good balance for both urban and off-road usage.

With the rear seats folded down, the 2020 Lexus GX offers a generous luggage capacity of 1832 liters (64.6 cubic feet). This expanded cargo space makes the GX practical for carrying large amounts of gear, luggage, or bulky items, making it ideal for family trips or outdoor adventures where flexibility in cargo space is essential.

The 2020 Lexus GX, with a length of 4879 mm (192 inches), width of 1885 mm (74.2 inches), and height of 1875 mm (73.8 inches), generally fits comfortably into a standard residential garage. Standard garages typically offer around 2440 mm (96 inches) width and 4570 mm (180 inches) depth, so while the GX is relatively long, most two-car garages or larger single garages will accommodate it without difficulty, taking care with clearance in tighter spaces.

Compared to the pre-facelift J150 Lexus GX models, the 2020 facelifted GX maintains very similar dimensions, with minor tweaks mainly to exterior styling and technology rather than size. The length, width (1885 mm/74.2 inches), and height (1875 mm/73.8 inches) remained largely consistent. The updates focused on refreshed aesthetics and improved interior tech rather than altering its sizable footprint.

The 2020 Lexus GX stands out in the mid-size luxury SUV category with its substantial dimensions—4879 mm (192 inches) in length and 2327 kg (5130 lbs) curb weight. Compared to competitors like the BMW X5 or Mercedes-Benz GLE, the GX is typically taller with higher ground clearance (206 mm/8.1 inches), emphasizing off-road capability. It offers a more rugged, body-on-frame SUV experience rather than the car-like design of many rivals.

The 2020 Lexus GX is equipped with 18-inch rims sized 7.5J x 18 paired with 265/60 R18 tires. This setup provides a good balance between ride comfort, off-road traction, and handling performance, fitting the GX's dual role as a capable luxury SUV able to handle both highway driving and rugged terrain.

The 2020 Lexus GX has a maximum weight (Gross Vehicle Weight Rating) of 2994 kg (6600 lbs). This figure includes the vehicle, passengers, cargo, and any additional equipment. A higher maximum weight rating is important for users who intend to tow heavy loads or carry many passengers and gear, reinforcing the GX’s utility as a rugged SUV capable of serious off-road and towing tasks.

The Lexus GX (J150, facelift 2019) uniquely blends luxury refinement with serious off-road capability. Its body-on-frame construction, ample ground clearance (206 mm/8.1 inches), and robust curb weight make it well-suited for rugged terrains, unlike many unibody luxury SUVs. At the same time, the interior offers premium materials and advanced technology, ensuring comfort and sophistication uncommon in traditional off-roaders.
