The BVRLA is encouraging members to clearly communicate both sets of CO2 data to customers to ensure transparency during the transition from the New European Driving Cycle (NEDC) test to the Worldwide Harmonised Light Vehicles Test (WLTP).
Since September 2017, newly type approved vehicles have undergone a test under the new WLTP. An NEDC figure will also be provided and used for tax purposes including vehicle excise duty and company car tax, until April 2020.
Customers should be made aware that the CO2 figure relating to their vehicle is likely to be different under the two testing schemes and so should consider both at the point of lease.
The NEDC figure is being calculated by converting the WLTP test result back to a NEDC equivalent through a software tool called CO2MPAS.
The BVRLA has produced a factsheet on the new testing regime available here.
