Opel Group is to begin publishing fuel consumption figures recorded under the proposed new WLTP 'real world' testing cycle from June this year.

"We at Opel strongly believe that the industry has to regain trust by increasing the transparency with customers and authorities. Opel takes this step towards RDE to show it can be done”, said Opel Group CEO Dr. Karl-Thomas Neumann.

“We announced in December in which direction we are going; now we are delivering the details. I ask the European Union as well as the EU member states and other European countries to accelerate alignment on test set-ups and test interpretations on real-driving-measurements to stop the existing uncertainty caused by test results that are hardly comparable.”

From the end of June 2016, and in addition to the official fuel consumption and CO2 information of Opel models, fuel consumption numbers recorded under the WLTP test cycle will be published, starting with the new Astra. These figures, which will show a fuel consumption range with a low and a high number, will first be offered for the model year 2016 Astra and published on a dedicated micro-website, creating more transparency. Figures determined under the WLTP test cycle will be published for further models later this year.

According to EU plans, the “New European Driving Cycle” (NEDC) will be replaced starting in 2017 with the more modern standard “Worldwide Harmonized Light Duty Vehicles Test Procedure” (WLTP). The WLTP is important to maintain standardized, reproducible and comparable results.
