The Lexus GX is a mid-size luxury SUV sold 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.
