There are many factors that play a role in whether a certain car is fuel efficient or not. Things like engine size, vehicle weight, transmission type, and aerodynamics can all affect how much fuel is saved, or in other cases, burned. With fully electric vehicles becoming more of a trend and hybrid vehicles being prominent for over a decade - all is not lost with gasoline-only cars when it comes to efficiency.
You probably don't expect to see gasoline-only cars raking in MPG numbers close to 40, but this is totally possible. Cars like the Mitsubishi Mirage is offered with a range of very small engines, that feature lighter materials, and an overall smaller car to allow for the best possible fuel efficiency while remaining significantly lower priced than most hybrids.
Using information from Fueleconomy.gov, we've compiled a list of the 10 most fuel-efficient non-hybrid cars.
1 Mitsubishi Mirage
Gas Mileage: 39 MPG
The Mitsubishi Mirage, being the most fuel-efficient and affordable non-hybrid car on this list, features a 1.2-liter three-cylinder engine with an automatic CVT (Continuously Variable Transmission). You can also opt for a five-speed manual transmission, however, this will lower the estimated fuel efficiency by approximately three MPG. With a 0-60 mph time of just under 11 seconds, this car is definitely not fast, but that isn't what you want when looking for a fuel-efficient vehicle.
Fuel Economy And Running Costs
| EPA-Estimated Fuel Economy | 39 MPG |
| EPA-Estimated Range | 359 miles |
| Annual Fuel Costs | $1,400 |

On the inside, the interior is probably what you'd expect from a new car that starts around $13,830. It is a four-door car though, and it does offer basic features such as standard automated emergency braking with pedestrian detection, a touch-screen with Android Auto and Apple CarPlay, and around 17 cubic feet of cargo space. Once the rear seats are folded down, this rises to 47 cubic feet of space.
