Proposal to amend the scope to allow type approval of vehicles of categories M₁, M₂, N₁ and N₂ with a reference mass not exceeding 2,840 kg at the manufacturer’s request as an extension from vehicles with reference mass not exceeding 2,610 kg, and to allow type approval of special purpose vehicles of categories M₁, M₂, N₁ and N₂ regardless of their reference mass at the manufacturer’s request, with the manufacturer demonstrating to the Type Approval Authority that the vehicle in question is a special purpose vehicle.

Proposal to amend the scope to allow type approval of vehicles of categories M₁, M₂, N₁ and N₂ with a reference mass not exceeding 2,840 kg as direct approvals rather than only as extensions based on approved configurations below 2,610 kg. The modification permits manufacturers to obtain type approval for vehicles within the 2,610 kg to 2,840 kg reference mass range regardless of whether lower-mass configurations of the same vehicle type are approved, addressing concerns that the previous restriction created market distortions affecting different manufacturers differently, a concern heightened by fleet electrification.

Proposal to amend para. 1 to clarify that type approval may be granted to vehicles of categories M₁, M₂, and N₁ with a reference mass not exceeding 2,840 kg at the manufacturer’s request, without requiring an existing approval of a configuration below 2,610 kg. The current wording restricts approval between 2,610 kg and 2,840 kg to extensions of existing approvals, creating market distortion. The concern is becoming more relevant with fleet electrification, as electrified vehicles are heavier and require different type designations in emissions-based regulations.
