maxresdefaultIf you are shopping for a new car, fuel economy is probably one of the first things on your mind. Gas prices in the United States are currently one of the lowest in years, but they will inevitably rise again. The amount of gas your car requires will directly influence your decision to drive it, when you have a choice of transportation. If you drive often, saving on fuel is essential. Most new cars are considerably more fuel-efficient than their predecessors, but what if you didn’t want to pay for gas at all? Here are the top five most fuel-efficient cars in the United States. All of them are electric.

BMW i3 Giga

This a four-seat hatchback with a rear-wheel-drive that is an electric car through and through. The car has an electric motor and an optional two-cylinder engine generator. The driving range on the motor is 75 miles, but it extends up to 130 miles with the optional engine installed. It takes about 4 hours to fully charge on a 240-volt charger. BMW i3 is a stylish-looking midsize electric car that is agile and fun to drive. Its fuel efficiency equivalent is 139 miles per gallon.

Mitsubishi i-MiEV

Mitsubishi managed to make the cheapest electric car currently available on the market. Priced at $22 500, it is definitely more affordable than BMW i3 or Tesla Model S, but it is not the fastest nor most attractive. The car range is just short of 60 miles. It takes a long time to charge: 21 hours on a standard 110-volt charger or 7 hours on a 240-volt charger. Its fuel efficiency is equivalent to 111 miles per gallon.

Ford Focus Electric

One of the most popular compact sedan models, Ford Focus boasts an electric version that has a fuel efficiency equivalent of 107 miles per gallon. The car runs on a 100-kilowatt electric motor. The battery takes less than 4 hours to charge fully for a 240-volt charger. Ford Focus Electric provides a quiet, agile ride with a range of up to 76 miles.

Nissan Leaf

Nissan Leaf is the most famous mass-produced electric car in the United States. Nissan Leaf has a range of 75 miles, just like Ford Focus Electric, but takes longer to charge (6 hours on a 240-volt charger or 16 hours on the standard 110 volts). The Leaf’s fuel efficiency equivalent is 106 miles per gallon. Overall, it is comparable to Ford Focus Electric, both in price and range, but has a more distinct appearance and more standard features.

Chevrolet Volt

The Chevrolet Volt is equipped with an electric motor and an 1.4 liter engine that extends its driving range from meager 35 miles to over 300 miles. The fuel efficiency equivalent in the electric mode is 99 miles per gallon. When driven with gasoline, the Volt’s fuel efficiency is 32 miles per gallon. The Chevrolet Volt is quiet and responds well to handle, but lacks room in the back and in the trunk. It takes 4 hours to fully charge on a 240-volt charger, whereas the standard 110 volts will extend the charging time to 10 hours.
