PSA Peugeot Citroen has comitted to publishing “real-world” fuel economy figures across its model ranges once the process has been overseen by an independent body.
A statement from the company said: “The plethora of recent reports on emissions testing has underlined the importance of compliance procedures and their proper application.
“In this context, the chairman of the Managing Board of PSA Peugeot Citroën asked the group's engineering teams to carry out verifications in this area and make recommendations for improvement.
“The group conducted an in-depth review of its situation with regards to emissions and fuel efficiency.”
Peugeot Citroen confirmed that after its own internal investigations, “PSA confirms that its vehicles have never been fitted with any software or device that detects emissions testing and triggers a pollution treatment system, including for nitrous oxide (NOx), that is inactive in normal driving conditions”.
The group stressed that its vehicles are compliant and that 4,300 vehicles were selected at random off its production lines in 2014 to verify compliance with type approval.
