Is Lexus GX fuel efficient?

The Lexus GX is a luxury SUV known for its off-road capabilities and premium features, but it is not considered a fuel-efficient vehicle. The GX's large size, powerful engine, and heavy-duty construction contribute to its relatively low fuel economy compared to other SUVs in its class.


Fuel Economy Ratings for the Lexus GX


According to the U.S. Environmental Protection Agency (EPA), the 2023 Lexus GX 460 has an estimated fuel economy of 16 miles per gallon (mpg) in the city, 19 mpg on the highway, and 17 mpg combined. These ratings are on the lower end for a midsize SUV, with many competitors achieving significantly better fuel efficiency.


Factors Affecting the Lexus GX's Fuel Efficiency


The Lexus GX's poor fuel economy can be attributed to several factors:



  • Large, Powerful Engine: The GX is powered by a 4.6-liter V8 engine that produces 301 horsepower. This large, powerful engine requires more fuel to operate compared to smaller, more efficient engines found in many other SUVs.

  • Heavy-Duty Construction: The Lexus GX is built on a truck-based platform, with a body-on-frame design that is heavier and less aerodynamic than car-based SUVs. This added weight and less streamlined design contribute to the vehicle's lower fuel efficiency.

  • Four-Wheel Drive System: The GX comes standard with a four-wheel drive system, which adds additional weight and mechanical complexity, further reducing fuel economy.


While the Lexus GX may not be the most fuel-efficient SUV on the market, its off-road capabilities, luxurious interior, and Lexus brand reputation make it a popular choice for some buyers who prioritize those features over maximum fuel efficiency.
