WLTP
A standardised testing procedure is stipulated by law to measure the consumption and the CO2 emissions of a car. Since 1 September 2017, passenger cars have been assessed using the new Worldwide Harmonised Light-Duty Vehicles Test Procedure (WLTP). This replaces the previous NEDC (New European Driving Cycle) process. More detailed information about the introduction of the procedure can be found in the FAQs.
