Abstract: Hybrid electric vehicles have the advantages of good fuel economy and low emissions compared with traditional fuel vehicles, so they become the focus of research in present automotive field. Recently promulgated China-VI light-duty vehicle emission regulation introduces real driving emission (RDE) test from European standard. Based on the requirements of the regulation, three hybrid electric vehicles (HEVs) and three gasoline vehicles with same displacement are selected to conduct RDE test, with the pollutant emission characteristics of HEVs analyzed and some suggestions for further improvements of current RDE regulation given.

Key words: HEVs, real driving emission
