PSA Peugeot Citroen has announced that it will be publishing fuel economy figures for its “main vehicles” based on actual real-world testing conditions. The move is seen as a pre-emptive measure in light of the recent dieselgate scandal that rocked the automotive industry.

As part of the announcement, the French manufacturer also reiterated that none of its vehicles have ever been fitted with any software or device that attempts to dupe emissions tests. This includes systems that are capable of detecting if a vehicle is undergoing testing, triggering a pollution treatment system, including for nitrogen oxides (NOx), that is inactive in normal driving conditions.

The group stated that to ensure compliance, 4,300 vehicles were selected at random off its production lines in 2014 for verification with type approval. PSA also say that it has implemented its “BlueHDi” Selective Catalytic Reduction (SCR) technology across all its diesel Euro 6 passenger vehicles, which it claims as being the most effective NOx treatment technology.

The technology is also said to meet the demands of the upcoming Worldwide harmonized Light vehicles Test Procedures (WLTP) standard, scheduled to be implemented in 2017. The new standard replaces the European NEDC procedure for type approval testing of light-duty vehicles.
