Summary:

The growing humanity concern about harmful effects of globalwarming in consequence of greenhouse gases (GHG) emission has beentranslated on CO₂ emission reduction targets for the next years inmany countries. These targets and regulations for exhaust gaspollutants with local effects have led to the introduction of newvehicular technologies as gasoline direct injection or hybridvehicles, for instance. New fuel developments, includingalternative ones, have already been an important contribution.In the United States, up to 2016, all manufacturers shallaccomplish with the average production target of 34.1 mpg, becoming49.6 mpg in 2025. In Europe, the 2015 target is 130 g/km of CO₂average emission by each manufacturer production and reduced for 95g/km in 2020. Japan, China, India and other countries have theirown limits defined for the next years too.In Brazil, the national labeling program informs the energeticefficiency level of each participant model and a classification ofthem but do not establish targets for CO₂ emission mitigation.Particularly, a very detailed discussion must take place regardingethanol participation on the fuel matrix.However, a comparison between contributions of each countrytarget is not direct, since different measurement procedures anddriving cycles are adopted. The USA applies 5 cycles to obtain fueleconomy, in Europe is used the NEDC cycle and Japan has the JC08,all of them looking for simulation of each local traffic condition.In Brazil the FTP-75 for urban path and HWFET for highway path areused, both coming from USA procedures.This work presents an overview of main driving cycles in theworld assessing their characteristics, main available vehiculartechnologies in each market and proposals of correlation betweenthe North American, also adopted in Brazil and the Europeanprocedures, compared to test results performed in the PetrobrasResearch Center (CENPES)
