German car companies are said to be discussing the idea of following Groupe PSA’s lead in publishing more realistic fuel consumption figures that are more reflective of – and closer to – actual real-world conditions, Automotive News reports.

Last month, PSA released what it tagged “real-world fuel consumption” figures for more than 1,000 variants of Peugeot, Citroen and DS vehicles, the new numbers being based on a testing protocol that was developed together with advocacy groups Transport & Environment (T&E) and France Nature Environment.

Now, German automakers are in talks to go the same route, with discussions currently being carried out within the VDA, the domestic industry association. In March, Volkswagen CEO Matthias Mueller revealed that the carmaker is talking with its German competitors in the VDA about a similar action to that taken by the French.

Asked about the matter, the VDA offered no hints on what testing protocol might be employed or whether any consumer and environmental advocacy groups would be invited to participate in discussions. All VDA president Matthias Wissmann said was that the association was “in constructive talks with the Federal Transportation Ministry on the question how we can improve transparency, but we have not concluded the discussions.”

Last month, T&E said that PSA’s new testing protocol indicated that in many cases real world fuel consumption test results were more than 40% higher than the certified figures published under the New European Driving Cycle (NEDC) system. It said the new protocol helped to show that fuel economy measurements can be reliable, representative and reproducible.
