Car makers are ramping up their efforts to ensure they are ready for the roll-out of tougher new emissions tests, which must be undertaken by all new cars from 1 September.
After that date, the Worldwide Harmonised Light Vehicle Test Procedure (WLTP) will apply to all new type approvals for cars. The test is designed to be more reflective of real-world driving than the outgoing New European Driving Cycle (NEDC). It will be complemented by a second test called Real Driving Emissions (RDE), which will be compulsory by 2021 and include on-road driving, rather than solely relying on test laboratory assessments.
Many car makers are already adjusting the stated CO2 figures of the models they sell to reflect WLTP. Also, since every model variant has to go through the WLTP test, many are simplifying their ranges.
There is also a push to sell cars that have only been approved under the outgoing NEDC test before September. After that date, only a small percentage of cars approved under the old regime will be allowed to be sold for another 12 months. This is expected to be 5% or 10% of a car maker’s overall sales but has yet to be confirmed by the government.
We spoke to a number of industry bosses to gauge how prepared they are for WLTP.
Jean-Philippe Imparato: Peugeot CEO -
“WLTP will not affect our business. We are [already] publishing our real-world fuel economy results with [French non-governmental organisations] Transport and Environment and France Nature Environnement.
There is no interference from PSA. You will see performance is outstanding for engine efficiency. I’m confident we’ll be fully on track against the best competitors.”
