Supporting the transition to WLTP

Project Brief

The New European Drive Cycle test procedure has been in existence for over 25 years and served as the laboratory testing procedure for new car homologation to determine air pollutants and CO2 emissions, fuel consumption, and for electric vehicles, range and energy consumption. The NEDC was replaced with the new Worldwide Harmonized Light Vehicles Test Procedure on 1st September 2017 for new models and all new car registrations on 1st September 2018.  The complete transition to WLTP takes place at the end of 2020. Over the transition period both NEDC and WLTP data will be available to car buyers potentially leading to confusion when comparing both new and second hand cars. Consistency, clarity and harmonization will be required from manufacturers and other stakeholders in the automotive industry responsible for presenting MPG, CO2, and electric range data in consumer information. 
 
The primary UK policy areas that will be affected by the introduction of WLTP are car taxation (VED and BIK), the plug-in car grant and manufacturer consumer information pertaining to CO2 emissions and fuel consumption. Legislative manufacturer consumer information covers the car fuel economy label and posters at dealers and printed marketing material.  WLTP will also have an impact on CO2, fuel economy and electric range data shown on car buying websites. LowCVP will be supporting the transition to WLTP through engaging with Government on relevant policy areas and communicating the introduction of WLTP to the automotive industry and consumers. 
 
LowCVP has created a decided web-portal on WLTP explaining the testing procedure in more detail, presenting timelines for policy transition and various guidance documents.

Objectives

  • To support the Department of Transport with preparing new regulations and guidance pertaining to the transition of WLTP in manufacturer consumer information. This will also include revising new car fuel economy labels for ICE, BEV and PHEVs. 
  • To produce guidance for the Automotive Industry outlining WLTP, UK policy changes and transition dates. This will also cover advice on presenting WLTP and NEDC data in consumer information channels. The audience for the guidance will be manufacturers, dealers, leasing companies and fleet consultants. 
  • To communicate the transition to WLTP to consumers by developing a simple and accessible information campaign engaging with dealers and the motoring media. 
  • To provide recommendations for improving the design of the new car label in 2020 taking into account the complete transition of WLTP in consumer information. This objectives is linked with PCWG project on car buyer research. 

Outputs

  • Recommendations to Government on VCA guidance and changes to the fuel economy and CO2 emissions database
  • Recommendations to Government for revising car fuel economy label to accommodate WLTP data. 
  • Production of guidance notes for the automotive industry.
  • A WLTP leaflet for consumer to be disseminated at dealerships
  • A toolkit for motoring media explaining WLTP introduction and new data. 
  • Recommendations for amending the new car fuel economy fuel economy labels for ICE, BEV and PHEV in 2020.
