Highest EPA combined MPG on US-market cars
Background
This ranking covers the highest EPA combined MPG figures listed in the findings for US-market cars. The data is narrowly focused on the top end of the market, with entries from 2022, 2023, and 2024, and it is dominated by battery-electric passenger cars rather than gasoline models, pickups, or a broad spread of utility vehicles.
At the top of the list, the [Hyundai Ioniq 6](/cars/hyundai/ioniq-6) Long range RWD leads at 140.0 MPG in 2024. The same Hyundai model also appears at 140.0 MPG in 2023. Lucid also reaches 140.0 MPG in 2023 with the Air Pure AWD and the Air Touring AWD.
For readers looking for the highest mpg cars 2024 or the best fuel economy cars 2024, the findings point first to the Hyundai Ioniq 6 Long range RWD at 140.0 MPG, followed by the Lucid Air Pure RWD and the [[Tesla Model 3 Long Range](/cars/tesla/model-3-long-range) RWD](/cars/tesla/model-3-long-range-rwd), each at 137.0 MPG.

The top entries are tightly clustered, with several models between 123.0 MPG and 140.0 MPG. The table below lists the models using only the make, model family, year, and MPG values shown in the findings.

This list answers several common reader questions about top mpg cars 2024, cars with highest mpg 2024, and highest mpg vehicles 2024. Within the findings, the leading 2024 entries are all electric cars.
What leads the 2024 field
Among 2024 models, Hyundai holds the top spot with the Ioniq 6 Long range RWD at 140.0 MPG. Just behind it are the Lucid Air Pure RWD and the Tesla Model 3 Long Range RWD, both at 137.0 MPG.
Other strong 2024 entries include the Hyundai Ioniq 6 Standard Range RWD at 135.0 MPG, the Lucid Air Touring AWD at 133.0 MPG, and the Tesla Model 3 RWD at 132.0 MPG. The Tesla Model 3 Long Range AWD appears at 130.0 MPG, while the Tesla Model 3 Long Range AWD-E is listed at 128.0 MPG.
For readers asking about the best mpg car 2024 or best gas mileage car 2024, the findings identify the Hyundai Ioniq 6 Long range RWD as the 2024 leader at 140.0 MPG. The dataset does not provide a gasoline-car leader for 2024.
Which brands appear most often at the top
The upper end of the ranking is concentrated among a small group of brands: Hyundai, Lucid, Tesla, and Lexus. Lucid and Tesla appear repeatedly across 2022, 2023, and 2024, while Hyundai places both Ioniq 6 variants near the very top.
| Make | Model examples in findings | Years shown | MPG figures shown |
|---|---|---|---|
| Hyundai | Ioniq 6 Long range RWD; Ioniq 6 Standard Range RWD | 2023, 2024 | 140.0, 135.0 |
| Lucid | Air Pure AWD; Air Touring AWD; Air Pure RWD | 2022, 2023, 2024 | 140.0, 137.0, 133.0, 131.0, 130.0, 129.0, 125.0, 123.0 |

| Lexus | RZ 300e | 2024 | 125.0 |
The findings name Hyundai as the leader make, and the leader model is the Ioniq 6 Long range RWD, with a leader MPG of 140.0.
2024 versus 2023 in the top ranks
The findings show that some headline figures held steady from 2023 to 2024, while others shifted. Hyundai’s Ioniq 6 Long range RWD is listed at 140.0 MPG in both 2023 and 2024. Hyundai’s Ioniq 6 Standard Range RWD is listed at 135.0 MPG in both 2023 and 2024 as well.
Tesla’s Model 3 RWD appears at 132.0 MPG in 2022, 2023, and 2024. Tesla’s Model 3 Long Range AWD is listed at 131.0 MPG in 2022 and 2023, then 130.0 MPG in 2024. Lucid’s Air Touring AWD is shown at 140.0 MPG in 2023 and at 133.0 MPG and 123.0 MPG in 2024.
For readers asking about best mpg cars 2023, the findings show a tie at 140.0 MPG among the Hyundai Ioniq 6 Long range RWD, the Lucid Air Pure AWD, and the Lucid Air Touring AWD.
Sedans dominate the highest-MPG list
The rankings are overwhelmingly made up of sedan and car nameplates. Hyundai Ioniq 6, Lucid Air, and Tesla Model 3 account for most of the highest figures in the findings. That matters for readers searching for best fuel mileage cars 2024 or highest mpg cars 2024, because the strongest results here come from passenger cars.
There are only limited utility-vehicle entries in the findings. The Lexus RZ 300e is listed at 125.0 MPG for 2024. Tesla’s Model Y RWD appears at 129.0 MPG for 2022, and Tesla’s Model Y AWD appears at 123.0 MPG for 2022.
For readers asking about best mpg suv 2024 or best mpg suvs 2024, the findings only provide one clear 2024 utility-vehicle entry: the Lexus RZ 300e at 125.0 MPG. No 2024 pickup or truck appears in the findings, so questions about best mpg 2024 pickup or best mpg truck 2024 cannot be answered from this dataset.
Trim and drivetrain details in the rankings
The model names in the findings show that trim and drivetrain configuration are tied directly to the listed MPG figures. Hyundai’s leading entry is the Ioniq 6 Long range RWD, while Lucid’s Air range appears in Pure, Touring, G Touring, and Dream forms.
Within Lucid’s 2024 entries, the Air Pure RWD is listed at 137.0 MPG and also at 130.0 MPG in another entry. The Air Touring AWD is listed at 133.0 MPG and also at 123.0 MPG in another 2024 entry. Lucid’s Air G Touring XR AWD appears at 129.0 MPG in 2024 and 131.0 MPG in 2023, while the Air Dream R AWD appears at 125.0 MPG in 2022.
Tesla’s records also separate RWD, AWD, and AWD-E versions. In 2024, the Model 3 Long Range RWD is listed at 137.0 MPG, the Model 3 Long Range AWD at 130.0 MPG, and the Model 3 Long Range AWD-E at 128.0 MPG. The findings do not explain the engineering reasons, but they clearly show that configuration details matter in any highest-MPG ranking.
What the findings do not cover
This is not a full market survey of every vehicle sold in the US. It is a list of top models by EPA combined MPG within the findings provided. It does not include a marketwide average, so questions about average mpg for cars 2024 cannot be answered here.
It also does not cover the UK market, so questions such as best mpg cars 2024 uk fall outside the scope of the findings. The topic is explicitly highest EPA combined MPG on US-market cars.
The dataset is also not a gasoline-only ranking. In practice, the listed leaders are electric models from Hyundai, Lucid, Tesla, and Lexus. That means questions about best mpg gas cars 2024 cannot be answered directly from these findings.
