The European Automobile Manufactures’ Association (ACEA) is calling for a timeline for the introduction of real-world driving emissions tests.

The tests will provide much more realistic emissions and economy figures including nitrogen oxides – the pollutants to blame for the ongoing VW emissions scandal.

The request by the industry association follows a European Commission regulatory body meeting, which has proposed elements needed to bring these tests to fruition

Without what it calls realistic timeframes and conditions, some diesel models could be unaffordable, forcing vehicle makers to withdraw them from sale, it claimed.

This could have repercussions upon consumer choice as well as employment in the wider automotive sector affecting not only passenger cars but also light commercial vehicles, where diesel is presently the technology of choice for operators, the ACEA said.

“Our industry is committed to contributing constructively to the efforts of the Commission and member states to upgrade emissions testing,” explained Erik Jonnaert, ACEA secretary general.

“Clarity and predictability will enable manufacturers to continue investing in technologies that meet even higher standards and contribute to the fight against climate change.”

The first stage of these real-world emissions tests, which applies to brand new vehicles, is due to commence from September 2017.
