Four More Companies Caught Cheating Emissions Standards
From The Guardian :
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 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 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?
VW Says Rogue Engineers, Not Executives, Responsible for Emissions Scandal
Volkswagen's US CEO testified Thursday that the decision to use emissions cheating software was not made at the corporate level. Instead, it was "software engineers who put this in for whatever reason," Michael Horn told a congressional panel that is investigating the scandal.
What's more, Horn told US lawmakers that the German automaker was withdrawing its application to sell 2016 autos with 2.0-liter diesel engines because they don't comply with US emissions standards. Horn testified that the 2016 vehicles were equipped with the same type of software that allowed millions of VW diesel vehicles to cheat pollution tests. "As a result, we have withdrawn the application for certification of our model year 2016 vehicles. We are working with the agencies to continue the certification process," Horn told the House Committee on Energy and Commerce Subcommittee on Oversight and Investigations.
The timing is perfect to throw the engineers under the bus.

When the VW defeat tactic was exposed, I wondered how could others not know. Of course, the EPA was fooled; that was the goal of VW. My impression is that manufacturers in the auto industry closely examine the cars of competitors. If they discovered it and didn't reveal their findings, that might suggest it is a common practice or a potential fallback.
There are circumstances where it might not be discovered: tear-downs are not too extensive; they rely on an EPA-like test; VW was using a different diesel technology than the everyone else (I don't know if that would make it more of less likely for a close examination).
