The consumption of fossil fuels by motor vehicles has increased greenhouse gas emissions in the atmosphere. The automotive industry has invested in environmental technologies to reduce these emissions. This study aimed to determine whether in light-duty vehicles deploying environmental technologies met the energy efficiency ratings of the Brazilian Vehicle Labelling Programme (BVLP) in 2013, 2015, and 2017. In 2013, Brazil implemented the ‘INOVAR-AUTO’ regulation to improve vehicle energy efficiency. Based on information from the BVLP database, the actual efficiencies of light-duty vehicles were compared with those mandated by the regulation. The effectiveness of the regulation was assessed using the growth rates of the energy consumption and annual A ratings. The results showed that certain powertrain technologies increased the energy efficiency, resulting in many vehicles with A ratings from the BVLP. The use of three-cylinder engines and variable valve timing (VVT) had the highest positive effects on improving the energy efficiency.
