Edmunds has a One-Year Road Test fleet. These are vehicles the team test drives for a year, whether it’s tracking it or commuting in it, so they can provide a more accurate review of the model.
One thing that the team at Edmunds noticed? Every single hybrid that they owned for a year lied. More specifically, the hybrids failed to meet their EPA fuel economy estimates. And this trend goes back a long, long time.
Hybrid EPA mpg versus the real mpg
Edmunds recalled a 2004 Toyota Prius the team owned for six years. Even though they loved it, it “didn’t come close to hitting the 46 mpg combined rating as predicted by the EPA.” They averaged 41 mpg instead.
That was over 10 years ago, but the trend continues. The Prius C they acquired in 2012 claimed 50 mpg, but the average they achieved was 45 mpg. The 2016 Prius was a bit closer, averaging 49 mpg, just three miles shy of the estimated 52 mpg.
This is a trend that’s far beyond Prius. Some stats:
- 2025 Honda Civic Hybrid
- EPA rating: 48 mpg
- Reality: 41 mpg
- 2026 Ford Maverick
- EPA rating: 47 mpg
- Reality: 33 mpg
- 2021 Toyota Sienna
- EPA rating: 37 mpg
- Reality: 35 mpg (not bad)
- 2006 Lexus RX 400h
- EPA rating: 26 mpg
- Reality: 20 mpg (almost)
- 2021 Ford F-150 Hybrid
- EPA rating: 24 mpg
- Reality: 19 mpg
- 2025 Toyota 4Runner TRD Pro Hybrid
- EPA rating: 23 mpg
- Reality: 18 mpg
- 2025 Hyundai Sante Fe Hybrid
- EPA rating: 34 mpg
- Reality: 26.7 mpg
- 2025 Toyota Grand Highlander Hybrid
- EPA rating: 27 mpg
- Reality: 23 mpp
- 2021 Honda CR-V Hybrid
- EPA rating: 38 mpg
- Reality: 29.6 mpg
Yikes. However, I can’t say I’m surprised at all.
How does the EPA get those range estimates?
The EPA refers to the U.S. Environmental Protection Agency. This is the branch of government that sends out the official mileage rating for these vehicles. The rating is known to differ from a vehicle’s actual range, since it’s initially based on automakers’ calculated and submitted ranges.
The EPA doesn’t verify every single vehicle, but when it does, it uses strict rules and scenarios, including highway driving, certain speeds, and weather conditions. It’s not going to reflect your specific experiences and situations all the time.
But it’s worth noting that it’s always wrong in the sense that it’s more, not less, than reality.
Recently, my colleague Dave McQuilling test drove the Lucid Gravity Grand Touring. This electric vehicle has an EPA-estimated range of 450 miles. He politely wrote: “I can’t debate the EPA’s figures; the government agency has its own rigorous testing process that’s applied equally to all vehicles. I can, however, say you shouldn’t expect to go 450 miles in a gravity, or any other EV for that matter.”
With an EV, you’re just not going to let it drop below 10% battery, and most brands recommend you don’t charge past 80%. Already, you’re not going to experience the full range. On top of that, the EPA seems to have exaggerated numbers.
Back the hybrids, however. The reason it’s more damning for hybrids is that these are supposed to be the more efficient way to drive with gas. It’s sorta their whole thing. But even with these false ratings, it’s still technically true.
