Some just like the big diesels for the sound they make with fully opened 5-" straight exhaust.
I heard some time back that the EcoBoost vehicles qualified for a substantial PZEV tax credit. Was that ever a thing? Is it still a thing?
I first heard of this because of a Porsche that used a combination of combustion chamber design, and special catalysts, and a radiator with a catalytic coating. It was put into a special circular recycling wind tunnel which was filled with air simulating typical city smog levels, and run at 60mph for 1 hour. Before and after tests showed that the air had lower smog level after the vehicle was run, than before. And that's been a few years back.
Surprised they haven't done anything more with this. Probably temporarily squashed by the DOE via EPA
https://en.wikipedia.org/wiki/Mercury_Meta_OneFor those of you thinking that Diesels aren't clean or efficient, this concept vehicle was created with then-current technology in use 12 years ago, and still passes current PZEV levels. Why hasn't this drivetrain been imported? Because DoE, at the "request" of API-PAC, and backed by recent administrations, has blocked it's importation and given incentives to FOMOCO to keep even it's existence quiet.
Even a 1% improvement in average petroleum consumption results in billions of lost revenue in both taxable petro-co revenue, as well as lowered direct tax revenue, as petroleum is taxed per volume sold. (Gallon, in US) They simply will not allow any tech capable of significantly improving overall average MPG, to breach this market, until they finally get FED Tax Revenue to be anchored to
miles driven rather than
gallons consumed.
In California, they tried to pass a bill requiring every car to have a wireless odometer transponder device installed to vehicles, and transceivers at the pumps, so with every fill-up, they track what vehicle filled up where, when, how much fuel and how many miles driven. This didn't even make it through the State House floor, but it was written and is still out there somewhere.
They've even tried to implement a change to pound-mile road tax, which would hit every driver twice, and every person at least once, whether they own a vehicle or not, because of the trucking industry having to pass the enormous tax amount on to their customers, and ultimately to every consumer of anything that is carried by OTR trucks, parcel carriers, currier companies, etc. Only rail and air transportation wouldn't be affected. Fortunately this didn't fly either.
They will never allow us to have our cake, unless they can eat it too.
