VW Faking Emissions Values

[postmortemIA]

A couple days ago I saw the first TV ad from a law firm and just today a second, different law firm has a TV ad looking to form a class action lawsuit.

Heh, I just saw ad here on this post

Attention is now turning to the way diesels are tested for NOX emissions after Mercedes, Honda, Mazda, and Mitsubishi cars all failed under real world conditions.

I wonder how many miles were on the cars tested? Older cars usually do not do as sell as the same car new. Its why older cars have more leeway in emission testing.

Meeting the spec is not hard, the problem is it only takes 1 to cheat and the others have to push their numbers to try and compete. So meet spec or get less gas mileage/performance.

So could this mean that VW was simply the first to get caught?

Others only "worked with" regulators to rig the rules.
VW broke the already rigged rules.

Clean diesels are a scam, nothing more nothing less. But in some cases, it's a legalized scam with participation of authorities.

The European test protocol (NEDC) isn't particularly realistic - and features quite gentle acceleration (e.g. 0-31 mph in 26 seconds for the urban cycle and 0-43 in 41 seconds for the extra-urban cycle).

It's not impossible that this protocol simply doesn't result in very high emissions due to the low stresses on the engine. I know that I don't drive like that except in bumper-to-bumper traffic, whereas the overall urban NEDC cycle is much more free flowing.

However, because the cycle is quite stereotyped, it could also be possible to tune the engine most aggressively for the operating envelope of the test cycle, which would also result in higher real world emissions.

The EU legislators have been working on trying to get a "real world" driving cycle introduced, which would be much more complex and feature a much wider pattern of acceleration/deceleration and cruise speed with the aim of more accurately modelling real world driving and making "tuning for the test" much more difficult.

No, none of the others had the cheat software.

The others just pollute more in the real world, vs the emissions test.

Most likely, all cars pollute more in the real world because people don't drive like they are taking an emissions test.

You thought it couldn't get worse, didn't you...

The U.S. Environmental Protection Agency is investigating a second emissions-control software program in Volkswagen AG cars that were rigged to pass pollution tests, one that the automaker may have failed to properly disclose.

This...makes no sense. It's a second defeat device...that VW actually just disclosed to the EPA (they didn't find it, VW brought it up, it seems) - so what is the extra hoopla? We knew they were violating the requirements, and they've now come clean? Am I missing something?
