About Us

Welcome to WLTPfacts.eu, a question-driven website to inform consumers about WLTP, the new lab test for cars. Through a series of educational infographics, this website answers the most common questions about the WLTP test in a clear and simple way.

Besides setting out the benefits of WLTP, providing a transition timeline and explaining the differences between the new and old test, WLTPfacts.eu also addresses pressing consumer concerns related to vehicle taxation and fuel consumption.

This website is an initiative of ACEA, the European Automobile Manufacturers’ Association, which represents the 15 Europe-based car, van, truck and bus makers.
