> False. This fix does not substantially affect mileage.
What fix? This is not a fix. It doesn't actually bring the car into compliance. If gas cars were allowed to exceed emissions then they also would be more efficient.
> Gassers make just as much particulate, but it's of the most hazardous type, which means their particulate emissions are actually worse than diesel.
That's only true of direct injected gas engines. This is why I said "depending on the car you compare to". Either way, gas cars, even DI ones, are within the legal limits. These Diesels are not, even after the fix.
> Gasoline also has to be refined more than diesel
This isn't true anymore. Diesel is a highly refined product now also. Clean emissions requires clean and homogeneous input fuel and that means more processing.
> Gasoline engines are shit for the environment.
As are Diesels.
> You know that battery electrolyte isn't recycled, right? It's just disposed of and then replaced.
When? Look at the study on 15 year old Priuses, they virtually all have their original batteries. The battery isn't highly recyclable (yet), but the savings on fuel more than makes up for it. You're barking up the wrong tree here. Hybrids are a net win, even with the material of the battery accounted for.
> But I live in the boonies, so I would still have to do most of my driving on liquid fuel. And they are also quite expensive, to boot.
Not everyone is you. And in the US (which this article is about) Diesels aren't cheap either. Oh yeah, and they've been cheating too. They're not going to get cheaper when they add the equipment needed to conform to emissions regulations.
> My prior car was a 300SD, which was a bit better on mileage and which ran on a more environmentally-friendly fuel.
That car is a rolling smog bank and you are trying to talk about how your input fuel was renewable? Seriously, have you looked at the emissions standards it was required to conform? They were a joke in the US and a double joke in Europe. It's far filthier than its contemporary gas cars and really bad compares to any modern car of any sort.
