The new emissions tests could have a significant effect on some new vehicle orders.

Although the WLTP (Worldwide Harmonised Light Vehicles Test Procedure) is now in effect for all new vehicles, the Government will continue using its previous system (NEDC – New European Driving Cycle) for taxation purposes until April 2020.

This means cars that have already undergone the WLTP will need their CO₂ emissions figures converted into NEDC figures using a special simulation model. These will be called NEDC-correlated figures; or NEDCc, for short.

The challenge for companies is that these NEDCc figures are likely to be different from those generated by the original NEDC. This could affect taxes, of course, but some businesses also have limits on CO₂ emissions in their company car policies. The difference between NEDCc and NEDC could mean a car that was under the cap when it was ordered is now over the limit. We are currently working with manufacturers to discover the NEDCc figures as soon as possible.

In addition, many manufacturers are experiencing delays and upheavals to their production schedules because of the WLTP changes.
