Providing testing transparency: Opel latest in a long line

One more to be added to the growing list – Opel says it is “committed to providing the testing authorities with transparency.” In a bid to do so, it will “voluntarily” take steps to meet future CO2 and nitrogen oxide (NOx) emissions guidelines by using a “transparent and credible approach.” This comes shortly after both Volkswagen and PSA Peugeot Citroen said they would use third party organisations to carry out real-world tests on their vehicles.

But the German OEM doesn’t plan to use independent tests to clarify fuel consumption and emissions. Instead, it will adopt the worldwide harmonised light vehicle test procedure (WLTP) in Q2 of 2016.
