What is the fuel consumption of a Lexus LX 570?

In the United States, the Lexus LX 570 typically records about 13 mpg in the city, 18 mpg on the highway, and around 15 mpg combined for the standard four-wheel-drive version. The vehicle’s large V8 engine and substantial weight contribute to modest efficiency relative to many other SUVs. Real-world mileage varies with driving conditions and cargo, but the EPA numbers provide a reliable baseline for comparison.


Official fuel economy ratings


These figures come from the U.S. Environmental Protection Agency (EPA) tests and reflect the typical ratings for US-spec LX 570 models with standard four-wheel drive. They are useful for year-to-year comparisons and for estimating running costs, though individual results can differ.


How the EPA tests are conducted


The EPA uses separate City and Highway tests to gauge a vehicle’s efficiency. The combined rating is calculated from these two results, offering a single figure for everyday use. Real-world results usually lag behind the city figure and align more with highway performance when driving at steady speeds on open roads.



  • LX 570 (US 4WD): approximately 13 mpg city, 18 mpg highway, 15 mpg combined (figures are representative across most model years).


Note that slight year-to-year variations can occur due to tire size, optional equipment, and testing updates, but the overall pattern remains consistent across LX 570 production years.


Real-world performance


Actual fuel economy you experience will depend on several factors, including how you drive, the load you carry, and where you drive. Owners report a pattern: lower mileage in city traffic and higher mileage on long highway trips, though the numbers generally stay in the low-to-mid teens for mixed driving.



  • Typical real-world ranges: City driving often yields roughly 12–15 mpg; highway cruising can reach about 18–21 mpg depending on speed, wind, and terrain.


In everyday use with a typical mix of passengers and cargo, many LX 570 owners report averages in the mid-teens combined. Terrains with steep grades or frequent stops can push results toward the lower end of that range.


Factors that affect fuel consumption


Several elements influence the LX 570’s mileage beyond the official ratings. Understanding these can help set expectations and guide driving or maintenance choices.



  • Vehicle weight and payload: The LX 570’s substantial curb weight and possible loads reduce efficiency, especially in city driving.

  • Drivetrain and tires: All-wheel drive and tire choice affect rolling resistance and energy use.

  • Terrain and climate: Hilly routes, headwinds, and temperature extremes can alter fuel consumption.

  • Maintenance and driving style: Regular maintenance, tire pressure, and smooth acceleration improve mpg; aggressive driving lowers it.


While these factors can swing mileage, the LX 570 remains oriented toward power and capability rather than high fuel efficiency, a trade-off reflected in its EPA estimates and real-world performance.


Context: LX 570 and its successor


In 2022, Lexus introduced the LX 600 as the successor to the LX 570, moving to a different powertrain and updated design. The LX 600 has a distinct fuel economy profile compared with the LX 570, so the numbers above apply specifically to the LX 570 as a model that spanned roughly the late 2000s through the early 2020s. For current buying or ownership decisions, you’ll be looking at the LX 600 or later models for newer efficiency technology.


Summary


The Lexus LX 570’s fuel economy in the U.S. is centered around 13 mpg city, 18 mpg highway, and 15 mpg combined for typical four-wheel-drive configurations. Real-world results generally fall within the mid-teens for mixed driving, with variations driven by load, terrain, and driving style. The LX 570 has since been succeeded by the LX 600, which brings a newer powertrain and different efficiency characteristics suitable for newer models.
