Fuel efficiency has become a significant consideration for many people when they purchase a new car. The rising cost of gasoline and increasing environmental awareness have led to an increased interest in fuel-efficient and environment-friendly cars. To make things easier for you, we've made a list of top the 10 vehicles that can grab your attention if fuel efficiency is one of the key factors for you when choosing a car.

How Does Fuel-Efficiency Measure? 

Fuel efficiency is a measure of how efficiently a car uses fuel to cover a certain distance. It's typically measured in miles per gallon (MPG) or liters per 100 kilometers (L/100km). However, it should be noted that fuel economy also depends on your driving style. Thus, two identical cars can demonstrate different fuel efficiency when they are driven by two different car owners.
