The Cars That Save The Most Fuel And Reduce Costs In 2025, According To The PBEV Of Inmetro. See Which Vehicles Are The Most Efficient, With Detailed Consumption And Performance Comparison!

With the constant rise in fuel prices, energy efficiency has become a crucial factor in choosing a new vehicle. The Brazilian Vehicle Labeling Program (PBEV) from Inmetro provides a detailed rating of cars available in the market, helping consumers make informed decisions. In 2025, this assessment covers 1,174 models and versions from 38 brands, ranking them from “A” to “E” in terms of efficiency.

The PBEV ranking focuses exclusively on models powered by fossil fuels, excluding hybrid and electric vehicles. Efficiency is measured in megajoules per kilometer (MJ/km), with lower values indicating more efficient cars. This article presents the most fuel-efficient cars in Brazil for 2025, highlighting their features and consumption.
