Several car manufacturers are facing fines in the UK due to possible manipulation of emissions values in diesel vehicles.

British owners of cars with diesel engines filed a lawsuit against some of the world's largest car manufacturers such as Mercedes-Benz and Ford at the High Court in London on Tuesday. The plaintiffs accuse the companies of cheating in emissions tests. A total of 1.5 million lawsuits are involved. The legal disputes could cost the car manufacturers at least six billion pounds (7.1 billion euros), said the plaintiffs' lawyers.

Mercedes-Benz - which is facing around 300,000 lawsuits - said in a statement: "We continue to believe that the lawsuits against Mercedes-Benz are without merit". The Stuttgart-based car manufacturer will vigorously defend itself with the necessary legal means. A Ford spokesman said: "We see no basis for these claims and will defend ourselves vigorously against them. Our vehicles and engines comply with all applicable emissions regulations."

The "Dieselgate" scandal unleashed by Volkswagen in 2015 has already cost the Wolfsburg-based carmaker more than 32 billion euros in retrofits, fines and legal costs. In 2022, Volkswagen agreed to pay 193 million pounds to settle claims from around 91,000 British drivers without admitting liability.
