An investigation into whether Renault was attempting to cheat emission regulations in a similar fashion to its rival Volkswagen (VW) has found no evidence that the company used ‘defeat devices’ in its vehicles.
To cheat environmental regulators, VW was found to have installed software that allowed the vehicles to detect when they were being tested on a flatbed and altered their output accordingly.
When the attempts to evade the regulations were discovered, shares in VW plummeted and the US government filed a civil lawsuit to sue the company for billions of dollars.
When it emerged that Renault was also being investigated over the scandal, its shares took a similar hit, falling by as much as 22 per cent in its worst trading day since they were first listed in 1994.
However, the car manufacturer has announced that the investigations to date found ‘no evidence of a defeat device equipping Renault vehicles’, after which the shares bounced back.
It said fraud investigators were looking at the way it uses exhaust emissions technology in an additional probe of parts and factories that follows an earlier investigation by the French government.
Although VW was the first company to have been found using the devices, the scandal has prompted investigations into other automobile manufacturers to ensure they have abided by regulations.
Diesel vehicles from the likes of Mercedes-Benz, Honda, Mazda and Mitsubishi have all been found to have higher carbon emissions than the authorities believed.
