Fuel economy is a key factor in a vehicle’s operating costs. This is especially notable after years of ownership. Find here the list of the most fuel-efficient vehicles.
To help purchasers make the right car buying decision, Consumer Reports have conducted extensive fuel-economy tests of modern models and selected the bests of each vehicle type.
Fuel efficiency figures are given overall, combined city and highway, in miles per gallon (MPG) or miles per gallon equivalent (MPGe) in the case with electric vehicles.
Well, the most fuel-efficient models – each in its group, are the following:
| Vehicle Type | Model | Overall MPG/MPGe |
| Hatchback | BMWi3 Giga | 139 |
| Subcompact Car | Mitsubishi Mirage ES | 37 |
| Compact Car | Hyundai Elantra Hybrid Blue | 48 |
| Roadster/Sport Car | Mazda MX-5 Miata Club (MT) | 34 |
| Midsized Car | Honda Accord Hybrid EX | 47 |
| Large Car | Toyota Avalon Hybrid XLE | 42 |
| Luxury Car | Tesla Model 3 Long Range | 130 |
| Wagon and Hatchback | Nissan Kicks SV | 32 |
| Small SUV | Tesla Model Y Long Range | 121 |
| Midsized/Large SUV | Tesla Model X 100D | 87 |
| Minivan | Chrysler Pacifica Hybrid | 84 on electricity, 27 on gasoline |
| Pickup | Chevrolet Colorado LT Diesel | 24 |
As we can see, all-electric vehicles hold a distinct advantage in fuel-efficiency rankings. Tesla dominates in the U.S. electric car market – 60-percent share in 2020. Tesla owners benefit not only from excellent fuel economy but from outstanding driving range as well.
By sales in the first half of 2021 in the country, the best-selling Teslas are the Model Y followed by the Model 3. Nevertheless, Americans still prefer non-electric pickup trucks and SUVs despite their mediocre fuel efficiency.
