Autovista announces that the first vehicles approved according to the WLTP procedure would discharge 25% more CO2 on average than under the NEDC regime. The company initially forecast a rise of 19%.
Plus 25%! The transition from the NEDC standard to the Worldwide Harmonized Vehicle Test Procedure (WLTP) for new vehicle registration would lead to an average 25% increase in carbon dioxide emissions, according to Autovista.
The automotive data specialist, who initially estimated the potential rise to less than 20%, relied on a sample of 1,000 vehicles from six manufacturers to achieve this result.
We note on this occasion that the transition to the WLTP procedure does not impact all manufacturers in the same way. Of the six actors studied by Autovista, the one who is doing best is seeing the average carbon dioxide emissions from its vehicles increase by only 4%. Conversely, the most penalized shows an average increase of 29%. Autovista preferred not to name the builders so as not to create, we suppose, a slight wind of panic.
The specialist also confirms that the options that are taken into account in the WLTP approval process can affect the results very negatively. Manufacturers will potentially have to revise their policy in this area.
Autovista finally warns countries whose taxation is strongly focused on carbon dioxide. This is the case of France, where the bonus / malus and the TVS (tax on company cars) are indexed on this single data. The tax increase generated by WLTP may be, in the current state of the scales, particularly dissuasive.
