WLTP coexisting with NEDC: ‘a mess until 2019’
Even if all new cars homologated after September 1st have to go through the new WLTP emission standards, data from the obsolete NEDC standard will still be in use until 2019. In terms of taxes, NEDC will still be the norm. “It’s as if we made the Belgian franc and the Euro coexist for two years. It’s a mess”, explains the spokesperson of a Japanese importer.
“A transition phase is scheduled and it creates confusion, we knew it”, adds another. Even if the new WLTP emission standard is enforced since September 1st, nothing has changed for consumers. On adverts, the indicated fuel consumption will still be from the NEDC test. It will be the case until 2019.
First WLTP cars in 2018
The WLTP test has been created to give more realistic data than the NEDC. Differences between theoretical fuel consumption and the real one was too important. Since September 1st, all new cars will have to go through the WLTP test to get the European homologation. The first ones will arrive in Belgium by the end of the year, in time for the Brussels Motor Show.
From September 2018, all cars will have to pass the WLTP test. Until then, and even beyond that, data from both standards will have to coexist. Cars’ technical specification sheets will indicate NEDC data with WLTP data in smaller letters until January 1st 2019.
Note that Opel already informs on WLTP data from all its recent models even if they were homologated before September. PSA also provides fuel consumption and CO2 emissions for 60 of its models tested in real driving conditions.
NEDC still in use for taxes
Joost Kaesemans from Febiac ensures that the government wants to keep NEDC – or some sort of NEDC data calculated from WLTP data – as the base for taxes. “The NEDC is still available for all cars”, he says, ”some will say that car makers are hiding more representative data, but this choice was made not to penalize the more evolved and less polluting cars”. No tax raise is currently on the horizon, until 2019.
