Core summary
Current-generation Lexus GX: a body-on-frame luxury SUV with full-time four-wheel drive and serious off-road hardware.
The Lexus GX is a luxury SUV distinguished from Lexus crossover models by its body-on-frame construction and full-time four-wheel-drive system. The current third generation was revealed in 2023 and entered production in November of that year. It uses the GX 550 name and is also marketed as GX 550h in the supplied reference. The current GX is built on Toyota's GA-F platform, shared with the J250 Land Cruiser Prado, and is larger than the preceding model in width, wheelbase and length.
For the United States, the GX 550 is listed in Premium, Premium+, Luxury, Luxury+, Overtrail and Overtrail+ grades. The Overtrail versions emphasize off-road use with standard 33-inch all-terrain tires and 18-inch wheels. The stated GX 550 powertrain is a 3.4-liter twin-turbocharged V6 producing 349 hp and 479 lb-ft of torque. Full-time four-wheel drive, low-range gearing, an 8,000-pound towing rating and Lexus Safety System+ 3.0 are central current-generation facts.
History & generations
Lexus introduced the GX 470 in 2002 as its third SUV. The first generation used the J120 platform and a 4.7-liter V8. It combined body-on-frame construction with full-time four-wheel drive, low-range gearing and equipment such as Adaptive Variable Suspension and Downhill Assist Control. An optional third row could increase capacity to eight passengers, while a side-opening rear tailgate was standard.
The J150 second generation arrived in 2009 as the GX 460. It retained the basic body-on-frame and four-wheel-drive formula but adopted a 4.6-liter V8, six-speed automatic transmission, standard KDSS and a power-folding third row for up to seven passengers. China also received the GX 400 with a 4.0-liter V6 from 2012 until its discontinuation in 2017. The J150 received facelifts for 2014 and 2020 model years, followed by minor 2022-model-year changes.
The J250 third generation was revealed in 2023, entered production in November 2023 and is the current model. It uses the GA-F platform and introduced the GX 550 name.
GX 470 (J120)
The first GX used a 4.7-liter V8, body-on-frame construction, full-time four-wheel drive and low-range gearing.
GX 460 / GX 400 (J150)
The second generation introduced a 4.6-liter V8, later joined by a China-market 4.0-liter V6 GX 400.
GX 550 / GX 550h (J250)
The current generation moved to the GA-F platform, adopted a squared-off design and introduced the GX 550 twin-turbo V6.
Body, platform & design
The current GX adopts a more squared-off exterior than the second-generation model. This shape is part of a broader redesign rather than a minor facelift. Compared with the preceding generation, the current GX is 95 mm wider, has a 60 mm longer wheelbase and is 70 mm longer overall. The Overtrail version is wider still, with a stated 115 mm increase over the previous model.
The design also establishes a clearer visual distinction between the standard luxury-oriented grades and the Overtrail models. Overtrail and Overtrail+ are the explicitly off-road-oriented versions, identified in the reference by their standard 33-inch all-terrain tires and 18-inch wheels. The supplied images include current GX 550 exterior views in Overtrail, Luxury+ and other named configurations, as well as older J150 and GX 460 vehicles. Those older vehicles belong to the preceding generation and should not be used to represent the current exterior design.
Engine & drivetrain
The current GX 550 uses the V35A-FTS 3.4-liter twin-turbocharged V6. The supplied reference gives outputs of 260 kW, or 349 hp, and 649 N⋅m, or 479 lb-ft of torque. It also states a maximum towing capacity of up to 3,600 kg, or 8,000 lb. The powertrain is paired with the current model's standard full-time four-wheel-drive system and low-range gearing.
The reference identifies the current generation as marketed under both GX 550 and GX 550h names, and describes the GX 550h as using a turbocharged hybrid-electric 2.4-liter four-cylinder engine. However, it provides no output, transmission, economy, battery or market-availability details for that hybrid version. The current GX 550 specification should therefore remain separate from the earlier GX 470 and GX 460 engines. Those older models used 4.7-liter and 4.6-liter V8 engines respectively, while the China-market GX 400 used a 4.0-liter V6.
Trim differences
The supplied reference lists six U.S. GX 550 grades: Premium, Premium+, Luxury, Luxury+, Overtrail and Overtrail+. It describes Overtrail and Overtrail+ as off-road-oriented models, with the Overtrail grade receiving standard 33-inch all-terrain tires and 18-inch wheels.
The GX 550 includes Lexus Safety System+ 3.0 and Lexus Interface with a 14-inch multimedia touchscreen as standard according to the extract. Japan began sales on 3 April 2025 with Overtrail+ and Version L grades, and the model received a Modellista styling kit there. These Japanese grades should not be assumed to match the U.S. lineup. The supplied image set includes vehicles identified as Overtrail, Luxury+ and other current GX 550 configurations, plus GX 550h images. Image labels establish the depicted model or grade but do not establish additional equipment.
Interior & seating
The current-generation reference confirms Lexus Interface with a 14-inch multimedia touchscreen as standard on the GX 550. The supplied image set includes three files labeled as GX 550h China-specification interior views, so the existence of interior imagery is clear, but those filenames alone do not establish universal equipment or market-wide interior specifications.
The previous J150 generation used a power-folding two-passenger third row and could carry up to seven passengers. That historical arrangement must not be transferred to the current GX without current-generation evidence. Likewise, earlier features such as Mark Levinson audio, rear-seat entertainment, three-zone climate control and heated second-row seats belong to the J150 description in the reference, not to the current-model specification. The current GX's cabin should therefore be described cautiously: it combines a Lexus luxury position with a 14-inch interface, while detailed seating and trim content varies by market and requires separate confirmation.

Efficiency & range
No consumption, emissions, electric range or official efficiency data is supplied for the GX 550 in the reference.
The current model's stated powertrain is a 3.4-liter twin-turbocharged V6 with 349 hp and 479 lb-ft of torque. That output and the vehicle's body-on-frame construction, full-time four-wheel drive and low-range gearing describe its capability-oriented engineering, but they do not provide a basis for estimating real-world efficiency. The GX 550h is identified as a turbocharged hybrid-electric 2.4-liter four-cylinder model, yet the extract supplies no hybrid output or economy figures. Buyers comparing versions should use market-specific official data rather than infer results from the older V8 models.
Safety & equipment
The current GX 550 includes Lexus Safety System+ 3.0 as standard, according to the supplied reference. The extract does not enumerate every system within that package or provide crash-test results for the current generation, so no additional current-model safety claims are made here.
Earlier GX generations had different safety equipment. The J120 added roll-sensing side-curtain airbags, tire-pressure monitoring and an optional rear camera during its updates. The J150 introduced active head restraints, ten airbags and available systems including pre-collision, driver monitoring and lane-departure warning. A 2010 GX 460 software recall followed an emergency-test concern involving vehicle-stability-control response, after which sales resumed with a software update. Those events are historical J150 information and should not be read as a current GX 550 assessment. Current safety equipment and results remain market-specific beyond the standard package named in the extract.
Strengths
The GX's defining strength is its combination of Lexus positioning with body-on-frame construction, full-time four-wheel drive and low-range gearing. The current GX 550 adds a 349-hp twin-turbocharged V6 and up to 8,000 pounds of stated towing capacity. Those characteristics support both long-distance utility and demanding terrain better than a conventional car-based crossover design.
The current generation also broadens the model's off-road focus through the Overtrail and Overtrail+ grades. The reference specifically identifies standard 33-inch all-terrain tires and 18-inch wheels for the Overtrail grade. Its GA-F platform is shared with the J250 Land Cruiser Prado, connecting the GX to a platform associated in the supplied material with off-road capability. The larger dimensions, current multimedia interface and standard Lexus Safety System+ 3.0 round out the model's functional changes without changing its basic identity.
A larger, more squared-off GX with stronger performance and expanded off-road focus.
Considerations
The GX is not simply a larger crossover. Its body-on-frame construction, full-time four-wheel drive and low-range gearing support off-road and towing duties, but those characteristics also define a more specialized vehicle than the RX.
The current GX is larger than its predecessor, with increases in width, wheelbase and length. Buyers should verify passenger capacity and grade-specific equipment in their market.
The GX 550h is identified in the reference, but its detailed output, availability and efficiency data are not given. The U.S. grades and Japan's grades also differ, so one market's trim names should not be generalized globally.
Recommended use
The current GX is suited to drivers who need a luxury SUV with genuine body-on-frame architecture, standard full-time four-wheel drive and low-range gearing. Its stated 8,000-pound towing capacity gives it a clear utility role, while the 349-hp twin-turbo V6 provides the published performance basis for that work. The Overtrail grades are the most directly aligned with the model's off-road mission because the reference gives them standard 33-inch all-terrain tires and 18-inch wheels.
It can also serve as a premium family or travel vehicle, but the supplied current-generation material does not confirm seating capacity, third-row layout or cargo measurements. Those details should be checked by market and grade. The GX is therefore a stronger fit for owners who value towing, rough-road access and a durable platform than for buyers whose priority is maximum urban efficiency or the packaging advantages of a crossover.
