A report by the French government into emissions by Renault diesel engines omitted details about why the engines emitted at least nine times as much nitrogen oxides as allowed by EU regulations.
Three members of the panel that tested the engines tell the Financial Times some of their findings were not told, including a suspicious automatic “pre-test” purge of the NOx trap in the Renault Captur SUV. The commission’s analysis showed the engine rapidly cleaned its NOx trapping device five times during prescribed test preparations, thereby preparing it to score well in the test itself.
The inquiry says its analysis of the Captur, along with 85 other models from a dozen carmakers, didn’t prove wrongdoing. But the report said further analysis would be necessary to rule out cheating.
France owns 20% of Renault. An unidentified government official tells FT that the state is “sensitive to the brand image of the companies it has invested in.”
