Proposal optimises the measurement accuracy requirements for chassis dynamometer equipment and the measurement acquisition of the
intake manifold pressure in system power testing for high-performance vehicles and makes editorial corrections.

The Electric Vehicles and the Environment informal group reported on amendments to UN Global Technical Regulations 21, 22, and 25 governing electrified vehicle power, battery durability for light-duty vehicles, and battery durability for heavy-duty vehicles. Proposed changes include revised test methods, boundary conditions, definitions, and alignment with UN Regulation transposition efforts. Future work includes investigating fuel-cell vehicles, charging power curves, and alternative test methods.
