An Anonymous Coward offers the following:
Volkswagen has admitted that more models gamed the emissions test, nearly doubling the number of cars affected. This now includes some Audi and Porsche models and other VW brands. From http://www.latimes.com/business/la-fi-volkswagen-problems-expand-20151105-story.html
The latest developments followed Volkswagen's admission Tuesday that it had understated the carbon dioxide emissions for 800,000 cars, widening the scope of the scandal.
Bob Lutz comments on a very toxic management culture at VW and offers his explanation for where things went sideways, http://www.roadandtrack.com/car-culture/a27197/bob-lutz-vw-diesel-fiasco/, suggesting that the management ruled by fear and threats.
And, a quote from a conversation with the dictator (former VW boss Ferdinand Piƫch) about tight (high quality) body panel fits on a VW, Lutz remembers:
...
"Yeah. I wish we could get close to that at Chrysler.""I'll give you the recipe. I called all the body engineers, stamping people, manufacturing, and executives into my conference room. And I said, 'I am tired of all these lousy body fits. You have six weeks to achieve world-class body fits. I have all your names. If we do not have good body fits in six weeks, I will replace all of you. Thank you for your time today.' "
This must really be serious now, none of the articles I saw used "xyz-gate" -- instead calling it a scandal or similar.

Every gas or diesel engine out there would fail the emissions test if it were measured under acceleration. On acceleration the CO & HC peg the meters. Doing a static test at a steady RPM has and always will be bullshit. It needs to be tested in parts per mile in real world road test conditions.

GP didn't say that the standards are impossible to meet, but that cars don't meet the standard during heavy acceleration which is true. They aren't required to meet the emissions targets at WOT and aren't tested for it. Since most people aren't driving with the pedal on the floor all the time it isn't seen as a problem. But one may choose to call it a legal loophole.

I've heard similar...but have not seen a real reference. Care to provide emission test results from WOT operation?

At least Ford and Dodge go full rich when the ECM sees full throttle signal from the TPS,

If they didn't do this, they would go full lean.
The problem would be if they went PAST stoichiometric for that CFM.
For instance, I have an old car. '79 chevy. 350 gen I block, 4 barrel Quadrajet.
I need tailpipe emissions tested annually. At idle (775 RPM +/-) and at 2500 RPM (+/-)
All measurements last time were less than a quarter of the allowable levels. (and quite close to each other at both throttle levels)
