If consumers knew which cars consume less fuel and provides better mileage, it would be a lot easier for them to purchase cars, especially if a list is provided to them, in the style of our coverage of the fastest cars in the world. But what makes a car fuel efficient for consumers is measured differently across the globe. Perceptions also vary regarding the fuel efficiency of a car. The most widely interchangeable terms used for fuel efficiency are "fuel economy" and "fuel consumption."
The higher the value in terms of distance traveled per unit of fuel used the better; this is determined when the term "fuel economy" comes to mind, whereas the reciprocal is used in "fuel consumption," in which case the lower the value the better. The former method is prevalent in the U.S. and the U.K., where fuel efficiency is covered using Miles per gallon, whereas kilometers traveled per liter is mostly used as a measure in some parts of Europe and Latin America, as well as some Asian countries like Japan. Cars are also tested based on fuel usage on different road types such as combined (includes city and highway), city and highway. Visit Insider Monkey to see the most fuel efficient cars today.
