Renault diesel cars emit the highest levels of toxic nitrogen oxides of all the big manufacturers and the French company’s recent models produce nine times the legal limit, tests have found.
Volkswagen, which has paid £15 billion to settle cases in the US over cheating emissions tests, now produces the least-polluting cars, according to Which?, the consumer group.
Jeep, Nissan, Hyundai and Ford scored badly in the Which? tests, producing at least five times the limit.
As engineers the world over have been saying, absolutely everyone has been lying. Because the basics of diesel technology are that you can’t reduce both CO2 and NOX in a cheap diesel engine. Only an expensive one.
Well done to the planners there.
