IDK if you've ever been through an emissions test (like the ones GM actually goes through), but they're a complete joke as to simulating real world behavior.
Does not matter. Your argument is something like, that by dumb luck auto manufacturers produced good emissions results and terrible results in the field.
As understand it, the EPA is saying that if a manufacture is engaged in your two stage approach, "Optimize for:- Simulated driving conditions, aka the Test Procedure [and achieve high fuel economy] - Real life driving [and achieve high power, low fuel economy]" then they are engaging in systematic fraud and are going to get hit big time.
You seem to think it's just a matter of technicalities in the test condition. I'd like references for that.
No. That's not my argument. It has absolutely nothing to do with dumb luck.
The EPA has a set of standards, and manufacturers optimize for those. That's it.
Cheating != optimization. Cheating is like a kid copying someone else's answers. Optimization is studying before the test. Completely different things. And optimization isn't illegal.
If you still don't get it, I don't know what to say, I can't explain it any further.
OK, I get that you saying "Cheating != optimization". That may be your opinion. It may be true in a moral sense.
However, I have good evident that VW's optimization was considered criminal in this instance. And Indeed, since many manufacturers do this, things are pretty dicey.
"“Developing an engine software to optimize certain aspects of an operation cycle that you know the parameters of is a challenge, but it is very possible,” says Thiruvengadam. “Knowing when to switch to the EPA-favorable cycle is the trick; it could be set up to detect the absence of steering-wheel movement, or, and this is known, we often turn off the traction control for testing purposes.” Either way, the result is the same: it turns the emissions controls on for EPA testing and off for real-world driving. Somewhat ironically, the presumed benefits of turning off the controls for normal driving include improved fuel economy and engine power." [1]
