Introduction
Today, fuel economy is a global priority. It's no longer just about spending less money, but also about protecting the planet.
The most fuel-efficient cars in the world are those that combine technology, design, and efficiency to maximize every liter of gasoline or diesel consumed.
This comprehensive guide presents the top 10 most affordable cars, analyzing their features, advantages, and interesting facts, so you can choose the ideal vehicle.
What is an economy car?
An economical car is defined by its ability to travel the greatest possible distance with the lowest possible fuel consumption. This efficiency is measured in kilometers per liter (km/l) or liters per 100 kilometers (l/100 km).
In addition, these vehicles typically generate fewer polluting emissions, helping the environment.
