How many miles per gallon does a Lexus rx350 get?

The Lexus RX 350 typically delivers in the mid-20s to high-20s miles per gallon combined, with exact numbers depending on the model year and drivetrain. For a precise figure, check the EPA rating for the specific year and configuration you’re considering.


What the numbers look like across recent generations


Fuel economy has shifted slightly with each generation and drivetrain option. Here is a general snapshot for contemporary RX 350 models.



  • RX 350 FWD (front-wheel drive): typically around 26–28 mpg combined.

  • RX 350 AWD (all-wheel drive): typically around 25–27 mpg combined.


Keep in mind that real-world results vary based on tires, driving style, and road conditions. Always verify the exact rating for the year and trim you’re considering.


Factors that influence real-world mpg


Several variables can push your actual fuel economy above or below the official ratings. Understanding these helps set realistic expectations.


Drivetrain and technology


The RX 350’s 3.5-liter V6 paired with an 8-speed automatic is tuned for efficiency, but adding all-wheel drive increases weight and mechanical losses, usually lowering mpg slightly.



  • Vehicle weight and aerodynamics

  • Driving style and speed consistency

  • Tire choice and condition

  • Maintenance status (air filter, spark plugs, oil, etc.)

  • Roof loads and cargo height


These factors combine to influence real-world mpg beyond the EPA’s laboratory estimates.


How to find the exact rating for your RX 350


For the precise miles-per-gallon figure, look up the specific model year, drivetrain, and trim on the EPA’s fueleconomy.gov site, or review the official window sticker and Lexus technical specifications for that year.


Summary


Across recent years, the Lexus RX 350 typically delivers in the mid-20s to high-20s mpg combined, with front-wheel-drive models edging higher than all-wheel-drive variants. For an exact figure, consult the EPA rating for the specific year and configuration you’re evaluating, and consider factors like driving habits, tires, and payload that affect real-world efficiency.

Does the Lexus RX 350 get good gas mileage?


The RX 350 has a 570-mile fuel range in the hybrid trim. Drivers in the 2022 Lexus RX 350 will get an estimated 27 miles per gallon when driving on the highway and 20 miles per gallon around the town to make a combined 23mpg.



How many miles can a Lexus RX 350 get on a full tank of gas?


A Lexus RX 350 can travel approximately 400 to 450 miles on a full tank, depending on the model year, whether it's front-wheel drive (FWD) or all-wheel drive (AWD), and your driving conditions. For the most recent models with EPA ratings of about 22-29 mpg combined and a 17.9-gallon tank, you can expect around 390 to 510 miles. 
Factors affecting your range

  • Model Year: Newer models often have different MPG ratings. For example, a 2024 RX 350 has a combined MPG of approximately 23-24 mpg, while a 2022 model has a combined MPG of around 22.8 mpg. 
  • Drivetrain: FWD models generally have better fuel economy than AWD models. For instance, a 2024 RX 350 FWD model gets 22 mpg city / 29 mpg highway, while an AWD model gets 21 mpg city / 28 mpg highway. 
  • Driving Conditions: City driving with stop-and-go traffic will use more gas than steady highway driving.
  • Driving Habits: Aggressive driving, such as rapid acceleration and hard braking, will reduce your fuel efficiency and range. 
  • Fuel Tank Capacity: While most Lexus RX 350 models have a 17.9-gallon fuel tank, hybrid versions may have different tank capacities. 



Is the Lexus RX 350 a woman's car?


Even though women love this SUV, it's a good buy for men as well, assuming they can put aside their macho tendencies.



What is the weakness of the Lexus RX 350?


Early Lexus RX 350 releases experienced steering issues, notably power steering fluid leaks from the rack and pinion system. Not only is this a massive safety hazard – it can also be costly to repair.
