Worldwide Harmonized Light Vehicles Test Procedure (WLTP)

The Worldwide Harmonized Light Vehicles Test Procedure, or WLTP, is a global standard for measuring fuel consumption, carbon dioxide emissions, and pollutant emissions from passenger cars and light commercial vehicles. Developed under the United Nations framework, it replaced older testing cycles such as the New European Driving Cycle in the European Union. WLTP uses more realistic driving profiles, including higher speeds, stronger acceleration, longer distances, and stricter test conditions. It also accounts for optional equipment that can affect vehicle weight and efficiency. The aim is to provide figures that better reflect real world driving performance and improve comparability across markets.
