The Worldwide Harmonised Light Vehicle Test Procedure (WLTP) is used to measure CO2 emissions, fuel consumption and pollutants and replaces the outdated New European Driving Cycle (NEDC) test. NEDC was based on theoretical driving, whereas the new test determines values using real-driving data.

The overall aim of the WLTP procedure test process is to present consumers and manufacturers with more accurate information about how a vehicle performs in actual on-the-road conditions, based on current engines. The test is also designed to harmonise testing procedures worldwide, given the importance of CO2 targets.
