WLTPtestiä

WLTPtestiä refers to tests conducted according to the Worldwide Harmonised Light Vehicles Test Procedure (WLTP). The WLTP is a global standard for determining the levels of polluting and non-polluting emissions, as well as fuel consumption and electric range of new cars and vans. It replaced the older New European Driving Cycle (NEDC) test procedure in Europe and other regions. The WLTP aims to provide more accurate and representative measurements of real-world driving conditions.

The WLTP test cycle is divided into four parts, each representing different driving speeds: low, medium, high, and extra-high. These parts are weighted differently to simulate a typical journey. The test also incorporates factors like varying acceleration and braking, different ambient temperatures, and the use of vehicle accessories. This comprehensive approach is designed to better reflect how vehicles are actually driven by consumers.

The primary goals of WLTPtestiä are to improve accuracy in reporting fuel economy and emissions figures, and to provide consumers with more comparable data across different vehicle models and manufacturers. The introduction of WLTP has also influenced the development of stricter emission standards and incentivized manufacturers to produce more fuel-efficient and lower-emission vehicles. The data generated from WLTPtestiä is used for regulatory purposes, vehicle labeling, and as a basis for environmental taxes in many countries.
