The Lexus GX (Japanese: レクサス・GX, Rekusasu GX) is a full-size luxury SUV sold in North American and Eurasian markets by Lexus, a luxury division of Toyota. The GX is built on the Toyota Land Cruiser Prado platform, 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 five-speed automatic was always standard, as was a full-time four-wheel-drive system 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.
In the Lexus lineup, the GX is positioned between the RX crossover and the premium full-size, off-road capable LX SUV (the Lexus badged Land Cruiser). All GX production has occurred at the Tahara plant in Japan, alongside the Toyota Land Cruiser Prado and the export-minded Toyota 4Runner. Both generations of the GX have been heavily based on the Prado and 4Runner, with updated frontal styling to better integrate with the Lexus lineup.
