I have read this too.^^^^
just a couple of years ago. VW said they have a sedan capable of 75 mpg. Turbo diesel I think. It wouldn't pass emissions...here in US.
So a 'detuned' version now making 4045 mpg is here in the States.
Can anyone please explain to me, how two cars going down the same road, where one is using almost half the fuel than the other, will pollute more???
Some have tried to explain to me that the 'formula' to compute emissions is actually based not only on % of pollutants in a sample exaust.... but also factoring in mpg as well.
Therefore, the more the vehicle gets for mpg, the 'cleaner' it must be. (per mile)
If vehicle "A" gets 35 miles per gallon.... and emits (this is just a wild guess here) 2 pounds of 'nasty' per mile
Using the formula that epa has intact means Vehicle "B" that gets 70 mpg must have only 1 pound of nasty per mile.
Which to me make some sense, if half the fuel is being burned per mile, shouldn't it make half the pollution? But to disallow because it is 'dirty' compared to something getting half the ecomomy doesn't make sense.
but then again..... what in gov't makes sense anyway?
Heck, if one car @ the 2 pound level of nasty per mile is good, why not let one in getting double the milage, putting out 1.75??
