PSA Peugeot Citroën and Transport & Environment will cooperate to publish real-world fuel economy data

November 23, 2015

In order to continuously improve fuel economy information in the interest of customers, PSA Peugeot Citroën and the NGO Transport & Environment have agreed to work together to measure and publicise real-world fuel economy figures as a first step by spring 2016, and pollutant levels including nitrogen oxides (NOx) as a second step with Euro 6.2 passenger vehicles by spring 2017.

The procedure will measure real-world fuel economy for each of PSA’s main passenger vehicle models with tests on open public roads near Paris in real driving conditions, with segments to include urban, extra-urban and highway driving.

The procedure will be included in PSA’s Quality processes. The process, its correct execution and the tests results’ measurement will be audited and validated by an internationally recognized independent third party. Discussions are underway with Bureau Veritas concerning the execution of this program.

Carlos Tavares, Chairman of PSA’s Managing Board, said: “This innovative initiative is a clear demonstration that a carmaker and independent NGOs can reach agreement for the benefit of customer information. This will also highlight the advanced technologies that PSA Peugeot Citroën is developing to contribute to fuel efficiency.”

Jos Dings, Director at T&E, said: “Real world measurements of CO₂ emissions and fuel economy will help drivers choose the most efficient models benefiting consumers, public health and the environment. We are confident that the work we plan to undertake with PSA can generate transparent robust results that everyone can rely on.”
