Is Lexus LX fuel efficient?

The Lexus LX, a luxury full-size SUV, is not known for its fuel efficiency. As a large, heavy vehicle with a powerful engine, the LX prioritizes performance and off-road capability over fuel economy. However, Lexus has made efforts to improve the LX's efficiency in recent model years.


Fuel Economy Ratings for the Lexus LX


According to the U.S. Environmental Protection Agency (EPA), the 2023 Lexus LX 600 has an estimated fuel economy of 17 miles per gallon (mpg) in the city, 22 mpg on the highway, and 19 mpg combined. These ratings are on the lower end for a full-size SUV, reflecting the LX's large size and powerful 3.5-liter twin-turbo V6 engine.


In comparison, some of the Lexus LX's competitors, such as the Cadillac Escalade and Lincoln Navigator, have slightly better fuel economy ratings, but they still fall short of more fuel-efficient SUVs in the segment.


Factors Affecting the Lexus LX's Fuel Efficiency


The Lexus LX's poor fuel efficiency can be attributed to several factors:



  • Large, Heavy Body: The LX is a full-size SUV with a curb weight of over 5,800 pounds, making it one of the heaviest vehicles in its class. The added weight requires more power and fuel to move the vehicle.

  • Powerful Engine: The LX's 3.5-liter twin-turbo V6 engine produces 409 horsepower and 479 lb-ft of torque, providing impressive performance but at the expense of fuel economy.

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

  • Large Dimensions: The LX's large size and boxy design create more aerodynamic drag, which reduces fuel efficiency at higher speeds.


While the Lexus LX may not be the most fuel-efficient vehicle in its class, the automaker has made efforts to improve its efficiency in recent years, such as the introduction of a hybrid variant. However, for those prioritizing fuel economy, there are more efficient options available in the full-size SUV segment.
