Mr. Danczyk presented the OICA proposal for plug-in hybrids, as announced at the 14th HDH meeting. The principle proposed is derived from the approach chosen for passenger cars within the WLTP work program. The group concluded that unlike for passenger cars it would be very difficult to develop the UFs for heavy duty vehicles. This is not considered feasible within the current HDH mandate. Mr. Dekker noted that the approach presented is used for passenger cars only with respect to CO2, not for criteria pollutants. This was also confirmed by Mr. Öhlund. Japan made clear that for emission the “worst” case should apply as the driver can choose to drive different modes but emission limits should apply anyhow. The chairman suggested to not handle plug-in hybrids now even though it is in the mandate of the HDH IWG.

It was agreed to not consider a special procedure for plug-in hybrids.
