31. [The HDH Chair] focused on the draft amendment to UN GTR No. 4 (GRPE-68-12) by providing details on the definitions, the concept of hybrid powertrain family, the approach considered, the content of Annex 8 (hardware in the loop simulation method) and 9 (powertrains method), as well as amendments aligning UN GTR No. 4 with UN GTR No. 11. The endorsement of GRPE was needed on this last point, since this is beyond the original HDH mandate. |
