Volkswagen CEO Matthias Müller said his company is considering publishing real-world fuel economy figures for its cars after rival automaker PSA Peugeot-Citroen did the same last week.

VW currently only publishes official NEDC (New European Driving Cycle) test figures that have been realized in a laboratory setting. With the company now trying to reestablish its credibility, it's looking at publishing real-world fuel economy figures for clarity’s sake.

“What PSA did, we are currently also thinking about,” Müller told AutoExpress on the sidelines of the 2017 Geneva Motor Show. “I do assume that in the foreseeable future, there will be something there.”

PSA Peugeot-Citroen’s real-world fuel economy figures, which it published on its international press website last week, were reached by attaching portable emissions kits on its vehicle range and driving the cars on public roads.

“This protocol predicts the real-world fuel consumption of vehicles travelling along a 92.3 km route combining urban, rural and motorway driving,” PSA Peugeot-Citroen said in a statement. “The vehicles tested travel on open routes in normal traffic conditions, with passengers and luggage. The use of air conditioning or heating is also mandatory. The routes selected have gradients representative of real-world usage.”

Müller said the new European emissions test (Worldwide harmonized Light vehicles Test Procedure, or WLTP) is more accurate than the NEDC test that is currently used. He described the new emissions test, which will be implemented this September, as being “more dynamic,” and “practically relevant,” even though some consumers believe it still isn’t stringent enough.
