AI-generated summary for informational purposes only. Not legal advice. See the original source for the authoritative text.
This regulation sets the testing and approval framework for light passenger and commercial vehicles under the WLTP system. It covers pollutant emissions, carbon dioxide emissions, fuel consumption, electric energy use, and electric range measurements. Vehicle manufacturers, importers, testing services, and approval authorities need to use these procedures when seeking or granting type approval. The practical effect is more standardized emissions and consumption data for new light-duty vehicles, including combustion, hybrid, and electric models.
