The Five Most Fuel Efficient Cars In 2021

Saving money on gas is something that most drivers take into account when buying a new car. When it comes to fuel efficiency, there are vehicles that perform better and ones that simply burn more fuel to make most of their engine performance.

In 2021, hybrid and electric vehicles are unmatched when it comes to efficiency, which is why comparing them to gasoline and diesel vehicles is like comparing apples to oranges.

Below, we are listing the five most fuel efficient gasoline and gas-electric (hybrid) vehicles.

The 5 Most Fuel Efficient Gasoline Vehicles

The Mirage and Mirage G4 variants are compact city cars powered by a 1.2 liter three-cylinder engine which is low in horsepower (78hp) but great when it comes to fuel efficiency. The CVT-equipped Mirage hatchback performs great in city, highway, and combined traffic.

2021 Hyundai Elantra (5.7-7.5l/100km)

Second on the list is the new Elantra, which is a sedan that uses a 2.0 liter four-cylinder engine powered by 147 hp and running on a very efficient regime with solid performance. Its fuel efficiency is best seen on highways, where it averages 5.7 on 100km.

2021 Kia Rio (6.0-7.2l/100km)
