Passenger car fuel economy statistics: U.S. real-world fuel economy by model year
The EPA’s estimated real-world fuel economy series covers new light-duty vehicles produced for sale in the United States. It is a fleetwide measure, so it describes the mix of vehicle types in each model year rather than passenger cars alone. The selected observations show a rise from 13.1 miles per gallon (mpg) in model year 1975 to 27.2 mpg in model year 2024. Those are final model-year figures. Model-year 2025 is preliminary: its 28.1 mpg estimate uses projected production volumes supplied before vehicles were sold. Model years do not correspond exactly to calendar-year sales and can span parts of adjacent calendar years. EPA, Table 3.1
| Model year | Estimated real-world fuel economy |
|---|---|
| 1975 | 13.1 mpg |
| 1980 | 19.2 mpg |
| 1985 | 21.3 mpg |
| 1990 | 21.2 mpg |
| 1995 | 20.5 mpg |
| 2000 | 19.8 mpg |
| 2005 | 19.9 mpg |
| 2010 | 22.6 mpg |
| 2017 | 24.9 mpg |
| 2024, final | 27.2 mpg |
| 2025, preliminary | 28.1 mpg |
The selected checkpoints describe several phases without filling in unreported years. The fleet estimate rose between the 1975 and 1985 observations, was lower in 1990, 1995, and 2000, and then measured 19.9 mpg in 2005 and 22.6 mpg in 2010. Later selected points are 24.9 mpg in 2017 and 27.2 mpg in 2024. This is a sequence of observations, not a claim that every intervening model year followed a smooth line. EPA, Table 3.1
The report labels 1975–2024 data final and distinguishes the 2025 projection as preliminary. That status matters when reading the most recent estimate: 28.1 mpg is not a final result for model year 2025. EPA estimates real-world fuel economy using 5-cycle testing and a current city/highway weighting of 43%/57%. The report also notes that methodology has evolved over time, a limitation for interpreting comparisons across the full historical span. EPA, Table 3.1 and methodology notes
Passenger car fuel economy statistics: sedan and wagon trends
EPA’s Sedan/Wagon category provides a vehicle-type view. It is not an exact synonym for the regulatory passenger-car class. In the report’s estimates, sedan/wagon real-world fuel economy was 13.5 mpg in 1975, when this type represented 80.6% of new-vehicle production. At selected later points, the measure was 23.0 mpg in 1985, 23.4 mpg in 1995, 22.9 mpg in 2000, and 26.2 mpg in 2010. EPA, Table 3.2
| Model year | Sedan/wagon real-world fuel economy | Sedan/wagon production share |
|---|---|---|
| 1975 | 13.5 mpg | 80.6% |
| 1985 | 23.0 mpg | — |
| 1995 | 23.4 mpg | — |
| 2000 | 22.9 mpg | — |
| 2010 | 26.2 mpg | — |
| 2019 | 30.9 mpg | — |
| 2024, final | 33.5 mpg | 23.7% |
| 2025, preliminary | 36.2 mpg | — |
The long-period comparison pairs a higher category fuel-economy estimate with a smaller production share: 13.5 mpg and 80.6% in 1975, versus 33.5 mpg and 23.7% in 2024. The report’s figures establish these values for their respective model years; they do not by themselves explain why production shares changed. The category’s selected fuel-economy observations include 30.9 mpg in 2019, followed by 33.5 mpg in final 2024 data. EPA, Table 3.2
For model year 2025, the preliminary Sedan/Wagon estimate is 36.2 mpg. As with the fleetwide 2025 figure, it relies on projected production volumes and should be kept distinct from final model-year results. EPA’s type labels are useful for comparing its reported categories, but they should not be substituted for a regulatory classification without checking the relevant definitions. EPA, Table 3.2 and notes
Passenger car fuel economy statistics: car SUV fuel economy
The EPA-defined Car SUV category had a 0.1% production share and an estimated 11.1 mpg of real-world fuel economy in 1975. In the selected observations, its share was 3.7% and its estimate 17.9 mpg in 2000; in 2010, the corresponding measures were 8.2% and 23.0 mpg. The category is distinct from Truck SUV in the report, and the label does not mean that every SUV belongs to the regulatory passenger-car class. EPA, Table 3.2
| Model year | Car SUV production share | Car SUV real-world fuel economy |
|---|---|---|
| 1975 | 0.1% | 11.1 mpg |
| 2000 | 3.7% | 17.9 mpg |
| 2010 | 8.2% | 23.0 mpg |
| 2011 | 10.0% | 23.5 mpg |
| 2019 | 11.7% | 27.5 mpg |
| 2024, final | 10.6% | 39.2 mpg |
| 2025, preliminary | — | 37.6 mpg |
The 2011 estimate was 23.5 mpg with a 10.0% production share. In 2019, the estimate was 27.5 mpg and the share was 11.7%. Final 2024 data show 39.2 mpg and a 10.6% share. These are paired readings of the EPA category’s production mix and fuel-economy estimate; the selected values do not establish the reasons for changes between those years. EPA, Table 3.2
For model year 2025, the preliminary Car SUV estimate is 37.6 mpg. The table does not provide a production-share figure for that preliminary observation in the selected data, so the figure is best read on its own. As a projected rather than final result, it should not be treated as a confirmed value or directly described as a finalized year-over-year change. EPA, Table 3.2
Passenger car fuel economy statistics: manufacturer comparisons
The manufacturer figures below cover new U.S. vehicles in EPA’s Sedan/Wagon category for model year 2024. They are manufacturer-level category estimates, not fuel economy claims for every model or vehicle sold under a brand. In the selected readings, Honda’s Sedan/Wagon production share was 46.0% of its model-year 2024 U.S. production mix across EPA vehicle types; this is a different measure and denominator from its category fuel-economy estimate. EPA, Table 3.4
| Manufacturer | Sedan/wagon real-world fuel economy, 2024 |
|---|---|
| BMW | 33.3 mpg |
| Ford | 21.9 mpg |
| GM | 28.7 mpg |
| Honda | 33.6 mpg |
| Hyundai | 35.9 mpg |
| Kia | 32.8 mpg |
| Nissan | 34.3 mpg |
| Toyota | 36 mpg |
| VW | 28 mpg |
| Tesla | 125.5 mpg |
Among these selected conventional-brand readings, Ford’s value is 21.9 mpg and Toyota’s is 36 mpg. The list also includes Tesla at 125.5 mpg. EPA’s reported fleet mpg values include battery-electric and plug-in hybrid values measured in miles per gallon equivalent (mpge), unless stated otherwise. That accounting distinction is essential: Tesla’s number should not be interpreted as a gasoline vehicle’s miles per gallon. EPA, Table 3.4 and fuel-economy definitions
The separate Car SUV figures show the same category and model year for four manufacturers: Ford was 44.3 mpg, Honda 34.8 mpg, and Tesla 113.7 mpg. These values also include the report’s treatment of electric-vehicle mpge where applicable. The manufacturer comparisons describe reported vehicle-type aggregates; they do not isolate the performance of a specific model, trim, or driving pattern. EPA, Table 3.4
Passenger car fuel economy statistics: hybrid and electric vehicle trends
Powertrain shares help explain what the vehicle-type averages include. In model year 2024, 30% of Car SUVs were battery-electric vehicles (BEVs), with another 3% plug-in hybrid electric vehicles (PHEVs). For Sedan/Wagon, 7% were BEVs and 1% were PHEVs. Those shares refer to new U.S. production within each EPA vehicle type, not to all vehicles on the road. EPA, section 3, p. 19
The report also states that Truck SUV fuel economy was 1.0 mpg higher due to 4% BEVs and 4% PHEVs in model year 2024. For pickups, fuel economy was 0.3 mpg higher due to 2% BEVs and no PHEVs. These are EPA’s stated contributions and powertrain shares for those categories; they do not describe Car SUVs or sedans, and the figures should retain their stated vehicle-type scope. EPA, section 3, p. 19
Across all new light-duty vehicles produced for sale in the United States, hybrids reached 15% of production in model year 2024, which the report describes as a new high. Mild hybrids accounted for about 35% of hybrid production in that model year. The first percentage is of all new vehicles; the second is of hybrid production only. Keeping those denominators separate avoids reading the mild-hybrid figure as a share of the entire new-vehicle market. EPA, section 4, “Hybrids,” pp. 64–65
Electric-vehicle efficiency enters this article’s mpg comparisons through EPA’s use of mpge for BEVs and PHEVs, which is included in fleetwide mpg figures unless the report says otherwise. That makes category and manufacturer aggregates broader than gasoline-only fuel economy. The production shares and the reported aggregate efficiency values answer related but distinct questions: one identifies the mix of powertrains, while the other reports an efficiency measure for a category or fleet. EPA, sections 3–4 and definitions
Passenger car fuel economy statistics: comparing fuel economy measures
EPA’s estimated real-world fuel economy is not interchangeable with a vehicle’s individual window label or a direct measurement of every driver’s fuel use. The report calculates the series using 5-cycle testing with current city/highway weighting of 43%/57%. It also cautions that the methodology has evolved over time. The figures are therefore best compared within their stated population, category, model year, and measure, with care when interpreting long-term changes. EPA, report methodology
Preliminary estimates can change when final production information is available. EPA’s comparison table shows both directions of revision. For model year 2024, fleetwide real-world fuel economy moved from a preliminary 28.0 mpg estimate to a final 27.2 mpg, a reported final-minus-preliminary difference of -0.8 mpg. For model year 2023, the preliminary estimate was 26.9 mpg and the final figure was 27.1 mpg, a +0.2 mpg difference. EPA, Table A.1
| Model year | Preliminary estimate | Final estimate | Final minus preliminary |
|---|---|---|---|
| 2024 | 28.0 mpg | 27.2 mpg | -0.8 mpg |
| 2023 | 26.9 mpg | 27.1 mpg | +0.2 mpg |
| 2022 | 26.4 mpg | 26.0 mpg | -0.4 mpg |
| 2021 | 25.3 mpg | 25.4 mpg | +0.1 mpg |
For model year 2022, the estimate changed from 26.4 mpg preliminary to 26.0 mpg final, a -0.4 mpg difference. For 2021, it changed from 25.3 mpg to 25.4 mpg, a +0.1 mpg difference. Earlier selected comparisons also show final values below preliminary ones: 24.9 mpg versus 25.5 mpg for 2019, and 24.7 mpg versus 25.6 mpg for 2016. In 2013, the final 24.2 mpg exceeded the preliminary 24.0 mpg. These are historical revisions to fleetwide estimates, not additional measurements of individual passenger cars. EPA, Table A.1
| Model year | Preliminary estimate | Final estimate |
|---|---|---|
| 2019 | 25.5 mpg | 24.9 mpg |
| 2016 | 25.6 mpg | 24.7 mpg |
| 2013 | 24.0 mpg | 24.2 mpg |
When using passenger car fuel economy statistics, identify whether the figure is fleetwide or specific to an EPA vehicle type, whether the year is final or preliminary, and whether electric-vehicle mpge is included. Those distinctions preserve the population and units behind each statistic and make the reported comparisons interpretable. EPA, Tables 3.1, 3.2, 3.4 and A.1
