WLTP: Impacts and Opportunities for Consumer Information

Developing the frameworks for the transition to WLTP certified vehicle information

Project Brief:

Passenger cars and light vans sold in the UK currently undergo type approval testing using the New European Drive Cycle. This test procedure determines the levels of air pollutants and CO2 emissions, fuel consumption (urban, extra urban, combined), and for plug-in electric and battery electric vehicles, their range and energy consumption. The NEDC will be replaced with the new Worldwide Harmonized Light Vehicles Test Procedure from 1st September 2017 for new models and all registrations from 1st September 2018. The test procedures are currently being developed through the UNECE World Forum for Harmonization of Vehicle Regulations. The European Commission is undertaking work to integrate the WLTP into European regulations.

There are a number of differences between WLTP and the NEDC. One of key differences is that the WLTP cycle has four phases and runs in two load conditions whereas the current NEDC has two phases run over a single load. This will have an implication on how emissions and fuel/energy consumption data will be reported on a vehicle’s certificate of conformity. One of key issues is that the certificate of conformity will show both NEDC and WLTP CO2 and fuel consumption data, this presents various challenges with regards to low carbon car policies and consumer information up to 2020.

The primary UK policy areas that will be affected by the introduction of WLTP are taxation system (VEV and BIK) plug-in car grants and the Passenger Car Regulations which relates to the provision of information regarding CO2 emission and fuel consumption to car buyers at the point of sale. Consumer information will also be affected notably the car fuel economy label and printed marketing material. Consideration will need to be given as to how new WLTP data will be presented on manufacturer’s and independent car buying websites.


Objectives

  • Working in partnership with a range of stakeholders, including Government and manufacturers, to steer a strategic and co-ordinated transition plan to new WLTP derived information taking into account low carbon car policy and the provision of new vehicle performance data.
  • To deliver clear guidance regarding transition to WLTP for car buyers.
