The Lexus GX is a medium frame SUV that has been in production since 2002. In the manufacturer’s range, the GX sits between the flagship LX and the RX crossover. At the heart of the GX is the well-known Toyota Land Cruiser Prado, which is easy to guess just by looking at the Lexus. External differences from the base model are not as significant as in other Lexus models.
The range of Lexus GX engines is quite simple, it includes only powerful power plants. The first generation was powered by a single 4.7L 2UZ V8, which gave way to a 4.6L 1UR on the updated version. This engine is also a V-shaped eight. For the Chinese market, the GX400 model was produced, with the well-known off-road V6 1GR. Diesel and hybrid models are not yet in the lineup.
The 4.0-liter V6 Toyota 1GR-FE engine has been produced in factories in Japan and the USA since 2002 and is installed in many pickups and SUVs, but is best known for the Land Cruiser Prado. There are two generations of this power unit: with VVT-i and Dual VVT-i type phase regulators.
The 4.6-liter Toyota 1UR-FE engine was introduced in 2006 as a powertrain for SUVs and full-size pickups, as well as executive models for emerging markets. Its main difference from 1UR-FSE is in the power system: distributed injection instead of direct.
The 4.7-liter Toyota 2UZ-FE engine was produced from 1998 to 2012 only at the American plant in Alabama and was installed on the most powerful SUVs and pickup trucks of the concern. At different times, there were two versions of this engine, with and without the VVT-i variable valve timing system.
