95% of diesel cars are breaking emissions limits – Which?

VW has borne the brunt of criticism for its admitted use of defeat devices in order to manipulate test results. However, the latest research from Which? found that many other manufacturers are breaking emission limits too.

Which? tests found that two-thirds of petrol cars break carbon monoxide (CO) limits set back in 2006. One car (Hyundai Veloster) produced more than five times the legal limit. Furthermore, Which? Claims that 95 per cent of diesel cars are breaking limits on nitrogen oxide emissions.

With this in mind, the consumer group has started a “come clean on emissions” campaign, which includes a petition so far signed by over 80,000 people.

Which?’s findings confirm separate reports from the BBC’s Panorama programme, which also concluded that raised questions about Opel/Vauxhall’s emissions results too.
