8. The Chair of the informal working group (IWG) on ACV introduced GRRF‑78‑17 reporting on the outcome of the group’s recent meetings, recalling the completion of the work on ACV and proposing to focus on Modular Vehicle Combinations (MVC).
9. GRRF noted the proposed updated Terms of Reference of the IWG (GRRF‑78‑16), converting its denomination to MVC and expanding its mandate. Following the concerns expressed by the expert from Germany on potential work conflict and/or overlap between the IWG on Regulation No. 55 and the IWG on MVC, GRRF agreed to monitor both informal groups’ progress to avoid such redundancy. Finally, GRRF adopted GRRF‑78‑16 as reproduced in Annex II of the GRRF-78 report.
