Worldwide Harmonised Light Vehicle Test Procedure (WLTP)
A new test for measuring fuel economy and Carbon Dioxide (CO₂) emissions is being introduced by Government for all vehicle manufacturers. It is called the WLTP (Worldwide Harmonised Light Vehicle Test Procedure).
WLTP introduction began in September 2017 but will not be fully rolled out until 2019.
What is WLTP?
WLTP is a new laboratory test for measuring CO₂ emissions and fuel economy for all new vehicles.
WLTP is replacing the current testing procedure, called NEDC (New European Driving Cycle), which was launched in the 1980s.
The aim of WLTP is to provide CO₂ emissions and fuel economy data which is closer to real world figures than NEDC.
WLTP testing was introduced on new vehicle models from September 2017.
