The Lexus GX is a mid-size sport utility vehicle (SUV) sold in North American and Eurasian markets by Lexus. Lexus introduced the first generation, known as the GX 470 in 2002, and subsequently became the third SUV to enter the Lexus lineup. 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. Now 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.
