The Lexus GX (Japanese: レクサス・GX, Hepburn: Rekusasu GX) is a mid/full-size luxury SUV sold in North American and Eurasian markets by Lexus, a luxury division of Toyota. The GX is based on the Toyota Land Cruiser Prado, from which it derives its off-road capability.

Lexus introduced the first generation, known as the GX 470 in 2002, and subsequently became the third SUV to enter the Lexus lineup. A full-time four-wheel drive system is standard with low-range gearing. The 4.7-liter V8 engine in the GX 470 was the same as used on the larger LX 470. The firm next introduced the second-generation model in 2009, badged GX 460 to reflect the switch to a 4.6-liter V8 engine. Lexus later released a lower displacement GX 400 in 2012 for the Chinese market, with a 4.0-liter V6 engine. The third-generation model introduced in 2023 uses the GX 550 moniker with a twin-turbocharged 3.4-liter V6 engine and GX 550h with a turbocharged hybrid electric 2.4-liter four-cylinder engine.

As of 2024, the GX is positioned between the larger LX or TX and the smaller RX. Though it is thought the GX has always been larger than the RX, from 2015 to 2022, the RX is slightly longer and slightly wider than the GX and therefore the GX was considered smaller. All GX production has occurred at the Tahara plant in Japan, alongside the Land Cruiser Prado and the export-minded Toyota 4Runner.

Some countries classify the GX as a full-size vehicle (e.g., Australia[2]), while some classify it as a mid-size vehicle (e.g., US[3][4][5][6]), depending on local regulations.

The name “GX” stands for “Grand Crossover”. Unlike crossover SUVs, the GX has body-on-frame construction and "Crossover" stands for it being in the middle of the range.[7][8]

Lexus introduced the GX 470 at the North American International Auto Show in January 2002 as a 2003 model, with sales commencing in November 2002. The GX development program began in 1999 following the J120 Toyota Land Cruiser Prado in 1997, with design work by Shoichi Fujiyoshi concluding in the first half of 2000.[9] The suspension shared its layout with the Toyota 4Runner equipped with the rear air suspension, while adding Adaptive Variable Suspension (AVS) and Downhill Assist Control (DAC). AVS could adjust damper firmness continuously while DAC modulated descents down slopes. Power came from a 4.7-liter, 32-valve, four-cam 2UZ-FE V8 engine originally rated at 175 kW (235 hp) at 4,800 rpm and 434 N⋅m (320 lb⋅ft) of torque at 3,400 rpm. Towing capacity was rated at 2,300 kg (5,000 lb) for the 2003 model year. Midway through the 2004 model year, the GX received an upgraded towing capacity of 2,900 kg (6,500 lb) with the addition of a much stronger frame-bolted tubular hitch. Ground clearance measured 211 mm (8.3 in), with an approach angle of 30° and a departure angle of 29° raised (25° normal).[10] The GX 470 carried a drag coefficient of Cd=0.38.[11]

The interior came equipped with two rows of seating, while an optional third row allowed up to eight passengers to be carried. However, the folding third row was tight with only 630 mm (24.9 in) of legroom. A Mark Levinson audio system along with a Rear Seat Entertainment System were available as options. A side-opening rear tailgate was standard.[11]

In 2003, for the 2004 model year, the GX 470's transmission was upgraded to a sealed unit with no dipstick. An optional Kinetic Dynamic Suspension System (KDSS) became available as a late-year addition. KDSS freed and adjusted the vehicle's stabilizer bars for greater articulation allowing the wheels to move with less restriction over uneven terrain, and used front and rear hydraulic pressure-sensing valves and larger stabilizer bars to reduce body roll during on-road conditions.[12] Safety upgrades for 2004 included a roll-sensing feature for the side curtain airbags, a tire pressure monitoring system, and an optional rear backup camera system.[13]

In 2004, for the 2005 model year, the GX 470's engine gained 26 kW (35 hp) with the addition of VVT-i for a total of 201 kW (270 hp).[13] This allowed the SUV to be certified as an Ultra-Low Emission Vehicle II (ULEV II) in the U.S.[14] Other upgrades included an enhanced navigation system, Bluetooth compatibility, and more voice commands. A Sport model joined the lineup, including the Kinetic Dynamic Suspension System and different styling such as smoked bezel headlamps, added chrome trim, and black birdseye maple wood.[15][16]

In 2005, for the 2006 model year, changes in SAE engine testing procedures resulted in a slight drop in the amount of stated power for the V8 to 196 kW (263 hp), and Lexus Link telematics was offered in North America.[13] For 2007, the GX 470 was largely unchanged, with upgrades for cabin electronics including a new generation navigation system, auxiliary input jack for devices like an iPod, DVD video playback when parked, and larger optional rear entertainment video screen.[14]

Finally, in 2007, for the 2008 model year, the GX 470 received styling updates, including a dark metallic grille, liquid graphite wheels, added exterior and interior chrome, revised turn signal lights, and added wood and body color options.[17]

The Lexus GX has won various awards including "Four Wheeler of the Year" in 2003 and 2004 from Four Wheeler Magazine, and Automobile Magazine All-Star for 2003 in the Mid-Size Sport-Utility category.[18] J.D. Power and Associates named the GX 470 the highest ranked premium luxury SUV in initial quality in 2005,[19] and Kelley Blue Book gave the GX 470 its Best Resale Value Award in 2006.[20]

The GX 460 debuted in China at the Guangzhou International Automobile Exhibition in November 2009. The redesigned model continued with body-on-frame construction, full-time four-wheel drive, an electronically controlled hi-lo transfer case, and a Torsen center locking differential. The Kinetic Dynamic Suspension System (KDSS) became standard. Power came from a new 4.6-liter 1UR-FE V8 engine producing 224 kW (301 hp) and 446 N⋅m (329 lb⋅ft) of torque, mated to a new six-speed automatic transmission. Fuel economy was improved over the prior generation,[22] while maximum towing capacity was 2,950 kg (6,500 lb).[23] The drag coefficient was reduced to Cd=0.35. The rear wiper was hidden under the rear spoiler, and while the tailgate remained side-opening, a flip-up glass panel was added.[24]

The interior added a power-folding, two-passenger third row which folded flat, allowing capacity for up to seven passengers, with the second row sliding or tilting for third-row access. Because the third row was no longer removable and used additional space, cargo capacity declined. A toggle switch replaced the transfer case's floor-mounted shift lever, and the gauge cluster added a steering wheel angle display for off-road situations.[23] Similar to before, a Mark Levinson sound system and two-display Rear Seat Entertainment System (RSES) were optional, while three-zone climate control, semi-aniline leather, and heated second-row seats and steering wheel were new options.[24]

Like its predecessor, Rear Adjustable Height Control (AHC) air suspension was offered on the GX 460 with an Adaptive Variable Suspension (AVS) system and Hill-start Assist Control (HAC). Additional electronic aids included the LX 570's Crawl Control system, Downhill Assist Control (DAC), and Active Traction Control (A-TRAC). The Torsen differential distributed a variable torque split when left unlocked, including a 40:60 (front: rear) ratio under normal driving conditions, a 30:70 ratio during cornering, and a 50:50 ratio when rear-wheel slippage was detected.[24]

Added safety features included whiplash-reducing active headrests and ten airbags, including front knee airbags and rear side torso airbags. New safety options include a Pre-Collision System, Driver Monitoring System, lane departure warning system, and Lexus Enform with Safety Connect telematics. Optional cameras located at the rear door, rear-view mirror, and passenger-side mirror provided views of the vehicle's sides.[23][25] Low-beam HID headlamp projectors were offered with an Intelligent High Beam feature which automatically dimmed the high beams depending on traffic conditions and an Adaptive Front lighting System (AFS) that swiveled the headlamps in corners.[24]

On May 28, 2012, Lexus China announced the market launch of the GX 400, which replaces the GX 460 in China. The engine option is now changed to the 4.0-liter 1GR-FE V6 engine that outputs 202 kW (271 hp) combined with a five-speed automatic transmission. Due to the power reduction, it takes 9.8 seconds for the GX 400 to accelerate from 0 to 100 km/h (0 to 62 mph). Compared with the outgoing GX 460, most standard equipment on GX 400 remains the same.[26] However, in November 2017, the GX 400 was discontinued in Chinese markets.[27]

On April 13, 2010, Consumer Reports in the United States urged customers not to buy the 2010 model year GX 460, giving it a "Don't buy, Safety Risk" label, its first such vehicle rating since 2001, following the results of a "lift-off oversteer" emergency test. This label was lifted on May 7, 2010.[28] In the high-speed test, the SUV was quickly turned with no pedal input, causing a sideways slide before the vehicle stability control (VSC) initiated a full stop. Consumer Reports said that the VSC acted too slowly, and if a wheel hit a curb or slid off the pavement, a rollover accident could occur. The shared platform Toyota 4Runner passed the test, and while Consumer Reports said it knew of no actual incidents, it recommended a software fix. The same day, vehicle maker Toyota expressed concern, thanked the magazine, and temporarily suspended GX 460 sales.[29] While noting that the SUV met all U.S. federal requirements,[30] on April 16 Toyota confirmed that its testing had duplicated the results.[31]

On April 19, 2010, a voluntary recall of the GX 460 was issued, along with the left-hand-drive Land Cruiser Prado, for a software update to fix the VSC response.[32][33] With the software update in place, sales resumed on April 29.[34] Vehicle stability control had been criticized by Wheels magazine for slow response speed on such models as the Toyota Kluger (known as the Highlander in North America),[35] while Drive noted that VSC had also been said to intervene too soon.[36] The Wall Street Journal pointed the lack of VSC a decade ago.[37]

In September 2013, the GX received a first facelift with the Lexus spindle grille design, new LED headlamps, and LED daytime running lights standard; LED fog lamps are optional. In the US pricing has been reduced by $4,750.[38]

It offers trims like Premium, Luxury, and off-road-oriented Overtrail models with features such as 33-inch all-terrain tires, increased ground clearance, and a one-inch suspension lift standard on Overtrail variants for 2025. The 2026 model year continues this legacy with intuitive technology like a 14-inch and wireless connectivity, reinforcing the GX's position as a sophisticated for adventure seekers.

Background and development

Origins and naming

The Lexus GX was conceived in the late as Lexus's first dedicated entry into the segment of luxury SUVs, aiming to provide a premium alternative to established competitors in the rugged off-road market. Development was led by Toyota's engineering division, with a focus on blending high-end refinement and off-road prowess to appeal to North American buyers seeking alternatives to British luxury models like the . The vehicle emerged as a luxury interpretation of the , sharing its core platform while incorporating Lexus-specific enhancements in styling, interior quality, and technology. The "GX" designation stands for "Grand Crossover," reflecting its positioning as a versatile, upscale that bridges traditional truck-based utility with crossover-like accessibility, despite its robust construction. This naming aligned with Lexus's broader strategy to differentiate its lineup through descriptive acronyms, where "G" evokes grandeur and "X" signifies crossover versatility. The initial model was badged as the GX 470, with the "470" denoting the approximate displacement of its in cubic centimeters, following Lexus's alphanumeric convention that ties numerical suffixes to engine size for clarity in model identification. Lexus announced the GX 470 on December 17, 2001, and formally debuted it at the 2002 in as a 2003 vehicle. This launch expanded 's SUV portfolio to three models—slotting between the unibody RX 300 and the full-size LX 470—and marked the brand's strategic push into mid-size luxury off-roaders. The GX 470 was positioned as a more durable alternative to the unibody RX models, such as the later RX 330, owing to its direct stablemate relationship with the RX yet featuring a truck-based body-on-frame design that handles abuse better, powered by the ultra-reliable 2UZ-FE V8 engine with fewer reported issues like radiator or transmission failures compared to the unibody RX. Subsequent generations evolved the naming to GX 460 and beyond, maintaining the alphanumeric format as engine technologies advanced, while preserving the "GX" core to emphasize its enduring grand crossover identity.

Platform and engineering foundations

The Lexus GX series is built on adaptations of the platform, providing a robust foundation for its off-road capabilities across all generations. The first-generation GX 470 (2002–2009) utilizes the J120 Prado chassis, the second-generation GX 460 (2009–2023) employs the J150 platform, and the third-generation GX 550 (2023–present) is based on the J250 series, with modifications for enhanced luxury and performance while retaining core Prado engineering elements. Central to the GX's engineering is its construction, featuring a ladder frame chassis designed for superior durability and off-road resilience. This employs high-tensile in strategic areas to boost torsional rigidity without excessive , enabling better handling and stability on uneven terrain. The frame's precision-welded design contributes to overall vehicle stiffness, a hallmark shared from the initial GX 470 through to the latest models. The GX incorporates a full-time four-wheel-drive system as standard, equipped with a limited-slip center differential that automatically distributes torque between the front and rear axles—typically in a 40:60 bias under normal conditions—and includes a locking feature for maximum traction in demanding scenarios. This setup ensures seamless power delivery on both paved roads and trails, with the differential adjusting dynamically to wheel slip for optimal grip. A pivotal off-road technology is the Kinetic Dynamic Suspension System (KDSS), first introduced as an option on the 2004 GX 470 and later standardized on subsequent models, which hydraulically connects the front and rear stabilizer bars to reduce sway bar resistance off-road for greater articulation while maintaining on-road stability. In the third generation, it evolves to the Electronic KDSS (E-KDSS), offering even finer electronic control for improved flexibility over obstacles. Complementing this, the GX maintains consistent engineering benchmarks like a base ground clearance of approximately 8.3 inches and a capacity of up to 6,500 pounds in early iterations, underscoring its foundational capability for heavy-duty tasks.

First generation (J120; 2002–2009)

Design and exterior styling

The first-generation Lexus GX (J120), introduced in 2002, adopted a boxy, angular exterior styling directly inspired by the , which helped establish the model's reputation for rugged luxury in the mid-size segment. This philosophy prioritized a commanding road presence with sharp lines, vertical tail lamps, and prominent fender flares to convey off-road prowess while incorporating upscale elements like chrome accents on the grille, side moldings, and door handles. Standard 17-inch six-spoke alloy wheels in a silver or optional chrome finish complemented the aesthetic, balancing durability with refinement. Measuring 188.2 inches in , 74 inches in width, and 74.6 inches in , the GX offered substantial dimensions that supported its construction for enhanced off-road stability. Unlike the unibody construction of its contemporary stablemate, the Lexus RX 330, this truck-based body-on-frame design provided superior durability, better handling of off-road abuse, and greater resistance to structural stress from heavy loads. Aerodynamic efficiency was achieved through subtle shaping, including a sloped hood and optimized underbody panels, yielding a of 0.38—respectable for a of its boxy proportions and contributing to composed manners. The and grille design evolved minimally from to production, retaining the Prado's functional layout but with refined projector-beam for improved and a bold horizontal chrome grille that integrated seamlessly with the badge, setting a premium tone. Available in a single base trim level, the GX came with various exterior color options such as , Pearl, and Timberland Pearl, while premium packages added features like a power moonroof for enhanced openness.

Interior and features

The first-generation Lexus GX offered a spacious and upscale interior tailored for family use, with three-row seating configured for up to seven passengers when equipped with optional second-row captain's chairs alongside the standard front bucket seats and foldable third-row bench. upholstery was standard on the power-adjustable front seats, which included heating and lumbar support, while genuine wood trim—such as Golden Bird’s-Eye Maple—accented the and panels for a refined luxury feel. The second-row 60/40 split-folding bench provided flexibility, and the third row could be stowed sideways or removed entirely to maximize utility. Cargo capacity behind the third row measured 13.2 cubic feet, expanding to 49.7 cubic feet with the third row stowed and the second row in place, or up to 77.5 cubic feet when both rear rows were folded or removed. This arrangement supported the GX's role as a versatile luxury suitable for both daily errands and longer excursions. Standard amenities underscored its premium positioning, including dual-zone automatic climate control with rear ventilation ducts, a 9-speaker premium AM/FM/cassette audio system with a 6-disc CD changer, and 10-way power-adjustable driver's seat. From the 2004 model year, buyers could opt for a navigation system with and a rear-seat setup featuring a and wireless headphones. An upgraded Mark Levinson audio system, delivering 240 watts through 14 speakers, was also available as an option for enhanced sound quality. The cabin's build quality emphasized comfort and refinement, with effective noise insulation that minimized road and wind intrusion during highway travel, contributing to a serene driving environment. Ride comfort was similarly praised for its smooth handling of paved roads, thanks to the suspension's balance of luxury and capability, making it suitable for long-distance journeys.

and off-road capabilities

The first-generation Lexus GX 470 was powered exclusively by a 4.7-liter V8 engine designated as the 2UZ-FE, producing 235 horsepower at 4,800 rpm and 320 pound-feet of torque at 3,400 rpm in its initial 2003-2004 configuration. For the 2005 model year, the engine received variable valve timing (VVT-i), boosting output to 270 horsepower at 5,400 rpm and 330 pound-feet of torque at 3,400 rpm.
