Lexus GX
Front-engine, four-wheel-drive

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

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.

Lexus introduced the GX 470 at the

approach angle of 30° and a departure angle of 29° raised (25° normal).[8] The GX 470 carried a drag coefficient of Cd=0.38.[9]

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.[9]

In 2003, for the 2004 model year, the GX 470's transmission was upgraded to a sealed unit with no dipstick. An optional

tire pressure monitoring system, and an optional rear backup camera system.[11]

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).[11] This allowed the SUV to be certified as an Ultra-Low Emission Vehicle II (ULEV II) in the U.S.[12] 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.[13][14]

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.[11] 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.[12]

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.[15]

The Lexus GX has won various awards including "Four Wheeler of the Year" in 2003 and 2004 from Four Wheeler Magazine, and

J.D. Power and Associates named the GX 470 the highest ranked premium luxury SUV in initial quality in 2005,[17] and Kelley Blue Book gave the GX 470 its Best Resale Value Award in 2006.[18]

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,[20] while maximum towing capacity was 2,950 kg (6,500 lb).[21] 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.[22]

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.[21] 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.[22]

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.[22]

Added safety features included whiplash-reducing active headrests and ten airbags, including front

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.[22]

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.[24] However, in November 2017, the GX 400 was discontinued in Chinese markets.[25]

On April 13, 2010,

software fix. The same day, vehicle maker Toyota expressed concern, thanked the magazine, and temporarily suspended GX 460 sales.[27] While noting that the SUV met all U.S. federal requirements,[28] on April 16 Toyota confirmed that its testing had duplicated the results.[29]

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.

Wall Street Journal pointed the lack of VSC a decade ago.[35]

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.[36]
