PARIS—Shares of French carmaker Renault plunged over 10% on Thursday as environmental officials revealed its diesel engines exceed emissions limits, although unlike the VW scandal, no cheating software had been found in the cars.
France’s Environment Minister Segolene Royal made the announcement after a commission she appointed submitted test results of French and foreign vehicles. The tests found carbon dioxide and nitrogen dioxide emissions in Renault cars to be too high, as were those of several non-French automakers that were not identified.
