1. If you were going to buy a fuel-efficient car, which three would you consider? Why?

Ford Fusion, Toyota Corolla and BMW i3

Explanation:

Fuel economy and fuel efficiency is one of the most important thing to consider when buying a car.

In United States, nearly 8 thousand gallons of petroleum are consumed by cars everyday. This cost a lot to the people's purse and most importantly it costs the atmosphere.

When we burn or use more fuel, the atmosphere gets more polluted by the exhaust of the fuel burning, and the world oil supply is depleting faster. This results in the rise of gasoline price. Thus, it is very necessary to plan before buying cars.

I would consider the cars Ford Fusion, Toyota Corolla and the BMW i3 while planning to buy a car because they are the most fuel efficient cars available in the U.S. They are also equipped with latest technology like cruise control which reduces the fuel consumption of the car.

The 2020 Ford fusion is a 6 speed automatic front wheel drive which gives the best driving experience and less energy wastage.
