What is the MPG for a 2020 Lexus 300h hybrid?

There is no 2020 Lexus 300h hybrid. The 300h badge was used on older Lexus hybrids (notably NX 300h and ES 300h) and Lexus did not offer a 2020 model with that name in the U.S. market. If you're researching a vehicle from around 2020, you’ll likely encounter NX, ES, or RX hybrids with varying MPG ratings.


What the 300h designation refers to


The "300h" label has been used by Lexus to denote a hybrid variant, typically with a powertrain configuration that sits in the 3.0-liter range on paper. In 2020, Lexus reorganized its hybrid lineup and did not market a new model under the 300h name in the United States. The badge remains a reference to earlier hybrid generations.


Where the 300h badge appeared in the past


Past Lexus hybrids that wore the 300h name include the NX 300h (a compact SUV produced roughly from 2014 to 2017) and, in some markets, the ES 300h sedan. Exact fuel economy figures varied by year, drivetrain (front- vs. all-wheel drive) and trim level.


Before listing typical MPG, note that exact numbers vary by year, trim, and driving conditions. Here are representative EPA estimates from older 300h variants:



  • NX 300h (2014–2017): roughly in the low- to mid-30s mpg combined, with variations by drivetrain.

  • ES 300h (2014–2018): around 40 mpg combined, with some years close to 39–41 depending on configuration.

  • IS 300h (Europe/other markets): sometimes used in other markets; mpg figures vary by region and year.


These figures give a sense of how the 300h name correlated with efficiency before 2020. For a 2020 purchase, you’d be looking at other Lexus hybrids rather than a 300h-badged model.


What to look for if you are shopping around 2020 hybrids


If you encounter a listing for a “2020 Lexus 300h,” treat it as a mislabel or a used-vehicle from an older generation. Check the model code, VIN, and EPA paperwork to confirm the exact powertrain. For 2020, common Lexus hybrids you might compare include models in the NX and ES lines, plus the newer plug-in options in the NX lineup.



  • Tip: Always verify EPA fuel economy labels for the specific year and drivetrain when comparing mpg claims.

  • Tip: Consider whether you want a regular hybrid (non-plug-in) or a plug-in hybrid (PHEV) when evaluating options around 2020.


In short, the 2020 lineup did not feature a new “300h” model, so mpg expectations should be based on the actual model you’re considering (NX 300h used timing, ES 300h used timing, or newer NX 450h+ PHEV or ES hybrids).


Summary


The Lexus 300h label was used on older hybrid models, not a 2020 model year in the U.S. market. If you’re researching around 2020, focus on the actual hybrids available that year (such as NX, ES, and RX hybrids) and check the EPA ratings for the exact year, drivetrain, and configuration. For quick reference, older NX 300h mid-30s mpg combined and ES 300h around 40 mpg combined are typical ranges for pre-2020 examples.

How many miles per gallon does the Lexus es300h hybrid get?


The Lexus ES300h's real-world MPG varies by year and driving conditions, but recent models typically achieve around 43-44 MPG combined. The EPA-estimated combined rating for the 2025 model is 44 MPG, with 43 MPG in the city and 44 MPG on the highway. Real-world figures reported by drivers are often in the range of 40-47 MPG, depending on factors like city versus highway driving and weather, says Reddit users. 

Model Year Combined MPG
2025 44 MPG (city: 43, highway: 44)
2024 44 MPG (city: 43, highway: 44)
2023 44 MPG (city: 43, highway: 44)
2022 44 MPG (city: 43, highway: 44)

Factors that can affect MPG:
  • Driving conditions: City driving, with its frequent stops and starts, can result in lower MPG compared to highway driving, though the ES300h's hybrid system is efficient in both scenarios. 
  • Weather: Colder temperatures can negatively impact fuel economy. 
  • Driving habits: Aggressive acceleration and heavy use of air conditioning can lower your MPG. 
  • Vehicle age: Older models may have slightly different fuel economy ratings. For example, the 2013 model is rated at 40 MPG combined.
