WLTP x Inmetro: how to understand electric car autonomy using SizesGrid
With the accelerated growth of the electric car market, one of the biggest questions consumers have is the vehicles' real range. When researching a model, it is common to find very different numbers depending on the acronym that accompanies them: WLTP or Inmetro. But after all, what do these acronyms mean and why do the values vary so much?
What is the WLTP Cycle?
WLTP (Worldwide Harmonized Light Vehicle Test Procedure) is the global standard used in Europe and several other parts of the world to measure fuel consumption, electric range and pollutant emissions. It was created to replace the old NEDC cycle, seeking to simulate driving conditions closer to reality, including different speeds, accelerations and temperatures.
The Inmetro Standard (PBEV) in Brazil
In Brazil, the body responsible for these measurements is Inmetro, through the Brazilian Vehicle Labeling Program (PBEV). Recently, Inmetro updated its rules for electric cars, applying a "correction factor" that reduces the published autonomy by around 30% in relation to the WLTP cycle. The objective of this reduction is to provide a more conservative and realistic estimate for Brazilian traffic and climate conditions, avoiding frustration for drivers.
Why does the difference matter?
Imagine buying an electric car that advertises 400 km of autonomy in the WLTP standard. When looking at the Inmetro sticker in Brazil, this same car can record around 280 km. This difference does not mean that the car has become worse, but rather that the testing methods and safety margins are different. Knowing how to convert and understand these values is essential for planning trips and daily use.
