What is the mileage of a Lexus ES 300h hybrid?
The Lexus ES 300h hybrid typically gets around 40 miles per gallon combined, with about 40 mpg in city driving and 39 mpg on the highway. Exact mileage depends on model year, trim level, wheel size, and driving conditions.
Here is a detailed look at official estimates and the factors that affect real-world efficiency for the ES 300h.
Reported mileage by model year
EPA estimates for the ES 300h in the United States have been fairly consistent across its production years. The following figures reflect the standard front-wheel-drive configuration commonly equipped on most trim levels; all-wheel drive was not offered on the ES 300h.
- 2013–2018 Lexus ES 300h: EPA-estimated 40 mpg city, 39 mpg highway, 40 mpg combined.
- 2019–2020 Lexus ES 300h: EPA-estimated 40 mpg city, 39 mpg highway, 40 mpg combined.
In practice, drivers often report real-world fuel economy close to the EPA numbers under typical highway or city commuting, with sometimes slightly lower results in extreme weather or heavy traffic.
What affects fuel economy
Several factors can push the ES 300h's mileage above or below the EPA estimates. Understanding these helps set realistic expectations for daily driving.
- Driving style: Gentle acceleration, steady speeds, and minimal hard braking improve efficiency.
- Traffic and trip composition: More highway cruising yields better mpg than frequent short trips in stop-and-go traffic.
- Tire size and condition: Properly inflated, low-rolling-resistance tires support higher fuel economy than underinflated or aggressive sporty tires.
- Climate control: Using air conditioning or heating increases load on the engine, reducing mpg.
- Vehicle load and aerodynamics: Extra cargo and roof racks increase drag and lower efficiency.
- Terrain and weather: Hills and cold temperatures can decrease mileage.
To maximize real-world mileage, drivers should monitor tire pressure, use eco-friendly driving modes when available, and plan trips to minimize unnecessary idling or abrupt starts.
Where to verify exact mileage
The most precise source is the EPA fuel economy label on your vehicle’s window sticker for new cars, or the EPA's fueleconomy.gov database for a given model year. If you are shopping used, check the sticker on that specific car or reference the EPA rating for that year and trim.
- New cars: check the window sticker at the dealership, which lists the exact city/highway/combined ratings.
- Used cars: consult fueleconomy.gov for model-year ratings and compare with the specific vehicle's docs.
For additional guidance, consult the owner's manual or ask a Lexus dealer about typical mileage for your chosen ES 300h configuration.
Summary
In summary, the Lexus ES 300h hybrid has long been rated by the EPA around 40 mpg combined, with about 40 mpg in city driving and 39 mpg on the highway for most model years. Real-world mileage varies with driving conditions, tire choice, and climate. Always refer to the window sticker for the exact figure on a given vehicle.
How much does it cost to replace a Lexus ES 300h hybrid battery?
At the dealership, the cost of replacing an ES 300h hybrid battery can range from $3,500 to $5,000, depending on the year and type of battery.
Does the Lexus ES 300h require premium gas?
No, the Lexus ES 300h does not need premium gas; it requires regular unleaded 87-octane gasoline. Most Lexus models, particularly those with turbocharged or high-performance engines, require premium fuel, but the ES 300h hybrid is an exception designed to run on 87 octane.
- Fuel requirement: The Lexus ES 300h is designed to run on regular unleaded 87-octane gasoline.
- Why it's different: Unlike other Lexus models that require premium for their high-compression or turbocharged engines, the ES 300h's hybrid powertrain is optimized for 87 octane.
- Other ES models: The standard ES 250 and ES 350 gas-only models also use regular unleaded 87 octane fuel, according to JM Lexus and Lexus of Freehold.
How many miles per gallon does a Lexus ES 300h hybrid get?
The Lexus ES 300h has an EPA-estimated fuel economy of 43 MPG in the city, 44 MPG on the highway, and 44 MPG combined. These figures are consistent across recent model years, including the 2025, 2024, 2023, and 2022 versions, and are driven by its hybrid powertrain that features a 2.5-liter inline-4 engine and an electric motor.
