All PSA Group passenger cars are now certified under the incoming lab test for emissions and fuel economy, the manufacturer has said.

The Worldwide Harmonised Light Vehicle Test Procedure (WLTP) is a more rigorous and longer test, developed to better reflect real-world fuel consumption and emissions than the New European Driving Cycle (NEDC) test, which used theoretical driving profiles and is being replaced on September 1.

Gilles Le Borgne, executive vice-president for quality and engineering at the group, which comprises Peugeot, Citroen, DS and Vauxhall, said: “Our technological choices to treat pollutant emissions – such as selective catalytic reduction for all diesel engines launched in 2013 and, more recently, the gasoline particulate filter for gasoline engines with direct injection – allow us to offer our customers compliant and environmentally friendly vehicles, and to keep our leadership on reducing emissions.”

By developing these systems, PSA said it was also aiming to be at the forefront of implementing the more stringent standards to reflect more realistic fuel consumption.

PSA Group has publicly supported the implementation of WLTP since 2015 and has published real-world fuel consumption and emissions figures for more than 1,000 of its vehicles since 2016.
