From The Guardian [theguardian.com] :
Mercedes-Benz, Honda, Mazda and Mitsubishi have joined the growing list of manufacturers whose diesel cars are known to emit significantly more pollution on the road than in regulatory tests, according to data obtained by the Guardian.
In more realistic on-road tests, some Honda models emitted six times the regulatory limit of NOx pollution while some unnamed 4x4 models had 20 times the NOx limit coming out of their exhaust pipes.
"The issue is a systemic one" across the industry, said Nick Molden, whose company Emissions Analytics tested the cars. The Guardian revealed last week that diesel cars from Renault, Nissan, Hyundai, Citroen, Fiat, Volvo and Jeep all pumped out significantly more NOx in more realistic driving conditions. NOx pollution is at illegal levels in many parts of the UK and is believed to have caused many thousands of premature deaths and billions of pounds in health costs.
The article goes on to state that the toxic emissions levels [wikipedia.org] are anywhere from 1.5 to 6 times higher in road use than in the lab tests. Of the 200 cars tested only five had emissions levels that matched what their test results. This is a rather distressing fact. It seems that we the public have been lied to (again) for many years now. The "clean diesel" might just be a myth.
Given that these manufacturers come from all over the world, how is it possible that this is an accident? Is there so much incest in the automobile industry that the code from one manufacturer has permeated the industry and the rest of the manufacturers are just waiting to get caught?
