RDE regulation in Brazil for Light Duty Vehicles will be made effective after Jan/2022. Brazil has some specific conditions and it is necessary to adapt the European RDE procedure in order to attend them: ozone as main pollutant, more than half LDV fleet are flexfuel, able to burn gasoline and ethanol biofuel but with high VOC emission, main big cities altitude close to 1,000 m and high road grade and type approval laboratory cycle based on FTP-75. The objective of this paper is to share advances and concerns about the work of Brazilian specialists in RDE Brazil procedure development. Some changes have already been introduced in the RDE procedure, but some concerns are coming to light, as the correct representativeness of FTP-75 as reference cycle, high ethanol emission at cold start below 20°C, tendency to high hydrocarbon and CO emission when driving at high positive altitude gain and temperatures higher than 30°C.
