Lexus GX engines

Lexus GXThe 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 Lexus GX was offered with 3 engines since 2002 (3 petrol). Displacement ranges from 4.0 to 4.7 liters, power output from 230 to 347 hp. 2 use a timing chain and 1 a timing belt. The longest rated lifespan belongs to the Toyota 1GR-FE (about 500,000 km).
