Efficiency, Economy, and Sustainability in Brazilian Traffic. Check Out the 10 Favorite Models Set to Conquer the Market in 2025
With the constant increase in fuel prices and the growing concern for sustainability, the search for more economical cars has never been more relevant. According to the National Institute of Metrology, Quality, and Technology (Inmetro), vehicles with the best energy efficiency in 2024 are already emerging as favorites for 2025.
The ranking is based on consumption in megajoules per kilometer (MJ/km) and takes into account performance with both gasoline and ethanol. In addition, the tiebreaker criterion is urban consumption with ethanol, which makes this study essential for those wanting to save daily and make more conscious choices, according to the website Terra Brasil Notícias.
What Characterizes an Economical Car?
Economical cars are those that use less fuel to travel a certain distance. The official classification is carried out by the Brazilian Vehicle Labeling Program (PBEV), coordinated by Inmetro. This program evaluates the energy consumption of vehicles in MJ/km, allowing consumers to compare different models accurately. In 2024, the most efficient cars achieve figures ranging from 10.7 km/l to 18.9 km/l in the city, and 9.2 km/l to 16.4 km/l on the highway. This translates into savings for both the wallet and the environment, with lower pollutant emissions.

In addition to lower consumption, economical cars also have the advantage of lower maintenance costs and less wear on parts. The Inmetro study, which remains relevant from 2023 to 2024, employs a rigorous methodology that takes into account everything from traffic conditions to driving style, ensuring reliable results for the consumer.
