Dieselgate: Five Manufacturers in Court in the UK
Ten years after the initial revelations, the Dieselgate scandal continues to send ripples through the automotive industry. A major new legal proceeding has just been launched in the UK, targeting five major automotive groups accused of equipping their vehicles with illegal devices that artificially reduced pollutant emissions during official tests.
The Automakers Involved
Among the companies targeted by this collective action are the French groups Renault and Stellantis, the latter notably encompassing the brands Peugeot, Citroën, Fiat, and Opel. Three other renowned automakers complete the list of defendants, although their names have not been officially disclosed in the preliminary documents.
This case is a continuation of the global scandal that erupted in 2015 when Volkswagen admitted to rigging emissions test results for eleven million diesel vehicles worldwide. The new British trial represents one of the largest collective actions ever brought in the country concerning unfair commercial practices.
The Allegations Against the Manufacturers
The plaintiffs claim that the manufacturers deliberately designed their diesel engines to detect when they were undergoing laboratory tests and then alter their behavior to comply with emission standards. Under real-world driving conditions, these vehicles allegedly emitted nitrogen oxide (NOx) levels up to forty times higher than the legal limits.
Lawyers representing the hundreds of thousands of affected owners argue that motorists were misled about the vehicles they purchased, both in terms of environmental impact and fuel consumption. They are seeking compensation for the damages suffered, contending that customers would not have bought these vehicles, or would have paid a lower price, had they been properly informed.
The Environmental and Health Impact
NOx emissions from diesel vehicles represent a major public health issue. These pollutants contribute to the formation of urban smog and are associated with various respiratory problems, including asthma and chronic bronchitis. Epidemiological studies have established a link between exposure to nitrogen oxides and an increased risk of cardiovascular diseases.
In the UK, where many cities struggle to meet European air quality standards, public and environmental group anger continues to grow. The revelations about the real emissions of diesel vehicles have accelerated the implementation of low-emission zones and increased consumer distrust of this technology.
Consequences for the Automotive Industry
This new trial comes at a pivotal time for the automotive sector, which is already facing the transition to electric vehicles and new environmental regulations. Manufacturers will not only have to face potential substantial financial penalties but also a further deterioration of their public image.
The case could also set an important legal precedent regarding corporate responsibility for misleading advertising and compliance with environmental standards. The rulings in this trial will likely influence other legal actions being prepared in various European countries.
Outlook and Regulatory Developments
Since Dieselgate, emissions testing procedures have been significantly strengthened with the introduction of Real Driving Emissions (RDE) measurements. New regulations now require vehicles to comply with emission limits not only in the laboratory but also on the road, with a limited margin of error.
Simultaneously, regulatory authorities worldwide have increased their vigilance and investigative capabilities, showing greater severity towards questionable practices. This British case demonstrates that, even a decade after the initial revelations, the legal consequences of the scandal continue to pursue the involved manufacturers.
The trial is expected to begin in the coming months and could last several years, given the technical complexity of the allegations and the large number of parties involved. Its outcome will have lasting repercussions on the commercial practices of the automotive industry and on consumer protection regarding environmental claims.
