How many miles per gallon does a Lexus ls460l get?

Typical fuel economy for the Lexus LS460L is around 18 miles per gallon combined, with about 16 mpg in city driving and 23 mpg on the highway. Actual results vary by year, trim, maintenance, and driving conditions.


Overview of the LS460L and its efficiency


The LS460L is the long-wheelbase version of Lexus’ flagship LS lineup, designed for rear-seat comfort and a smooth, luxury ride. Powered by a 4.6-liter V8 and an automatic transmission, it emphasizes luxury and performance over ultra-high fuel economy. EPA estimates provide a baseline for typical owners, but real-world mpg can differ based on how the car is used and maintained.


Engine and drivetrain


Most LS460Ls from the late 2000s through the mid-2010s used the 4.6L V8 (engine code 1UR-FSE) paired with a multi-speed automatic transmission. This setup delivers strong acceleration but is not optimized for maximum fuel efficiency, especially in city driving or with heavier loads.


EPA fuel economy estimates


Before listing the typical numbers, note that these figures come from EPA ratings commonly cited for the LS460L models with the 4.6L V8 and the standard automatic transmission. Actual mileage will vary by year, equipment, and driving style.



  • City: 16 mpg

  • Highway: 23 mpg

  • Combined: 18 mpg


Real-world driving often yields numbers near these estimates, but it’s common to see lower results in heavy city traffic or with frequent highway starts and stops.


Year-to-year variations and note on weight


Across its production span, the LS460L’s mpg figures remained clustered around the 16/23/18 range. Some years with additional equipment or heavier configurations could show slight dips (for example, around 15 mpg in city driving). The continuous improvements in tires, aerodynamics, and maintenance practices can also influence observed fuel economy.


Factors that affect mpg in practice


Several factors can cause the LS460L to deviate from the textbook EPA numbers. Understanding these can help set realistic expectations.



  • Driving style and conditions (city vs. highway, aggressive acceleration, frequent braking)

  • Vehicle load and added equipment (passengers, cargo, roof racks)

  • Tire type, width, and inflation pressures

  • Maintenance status (engine tune-ups, oxygen sensors, air filters)

  • Weather and climate (cold starts, air conditioning use)

  • Fuel quality and grade


In practice, a well-maintained LS460L driven primarily on highways at steady speeds is more likely to approach the higher end of the combined range, while city-centric or heavy-load use will typically push mpg downward.


Practical tips to maximize mpg


To improve efficiency from a LS460L without sacrificing comfort and safety, consider these approaches.



  • Keep tires inflated to the manufacturer’s recommended pressure.

  • Reduce weight and remove roof racks when not in use.

  • Drive smoothly: gradual acceleration, steady speeds, and early anticipation of stops.

  • Schedule regular maintenance to maintain engine efficiency (air filters, spark plugs, oxygen sensors).


Even with careful driving and maintenance, luxury sedans like the LS460L typically operate with lower mpg than compact or mid-size sedans, due to weight, aerodynamics, and comfort-focused features.


Summary


The Lexus LS460L generally delivers about 18 miles per gallon combined (roughly 16 mpg city and 23 mpg highway) across its typical production years with the 4.6L V8. Real-world results vary based on year, trim, maintenance, and driving habits. For buyers and current owners, maintaining proper tire pressures, minimizing weight, and practicing smooth driving are the most effective ways to approach the EPA estimates.
