VW admitting that CO2 and MPG figures on 800,000 gas powered cars could be wrong as well...
apparently quite a few of those are diesels as well (euro only)VW admitting that CO2 and MPG figures on 800,000 gas powered cars could be wrong as well...
Based on the latest version of the GREET model (GREET_2015) for "upstream" emissions (well-to-pump - WTP) and the vehicle emissions (PTW) of the Passat TDI based on the ICCT/WVU study, here is a comparison of the Passat TDI vs. the Passat 1.8T (using certified emissions of the PZEV version)...I wonder what the total 'emissions' footprint is of diesel vs gasoline, when you start from the point of pulling a barrel of oil out of the ground, going through the refining process of creating a gallon of diesel vs gasoline, and adding the comparison of diesel mileage in similar cars - let's say between a Passat TSI and a Passat TDI. Maybe it was already done, but I'd be curious to see the whole picture.
I've seen the charts comparing certified emissions, but I was curious to see the total emissions created from pumping a barrel of oil out of the ground, the refining process to diesel and gas, and the number of barrels per year consumed, sort of like a 'cradle to grave' comparo for a barrel of oil between a TDI and non-TDI.I wonder what the total 'emissions' footprint is of diesel vs gasoline, when you start from the point of pulling a barrel of oil out of the ground, going through the refining process of creating a gallon of diesel vs gasoline, and adding the comparison of diesel mileage in similar cars - let's say between a Passat TSI and a Passat TDI.

Right, this is the thing that makes me the most upset about this whole thing: the regulations are meaningless.My neighbor, who drives a Prius asked me how I felt driving our Golf TDI because it pollutes so much. She said I would be better off driving my Touareg because it uses gasoline.
If she only knew that it has a V8 FSI under the hood that only has to meet emissions standards of a light duty truck ��

If cars can only pollute X but trucks can pollute XXX and there is no restriction on trucks sold vs. cars then this isn't a system that encourages emissions reductions.
Being at TDIParts/IDParts now for almost a decade, I cannot count how many long time customers are workmen and use their Sportwagens as "trucks" instead of an F150 etc.
So, in this system, those who choose to get the Sportwagen to save $$ on fuel are punished versus those who choose to buy the truck. Its actually WORSE - due to CAFE standards they need to sell the fuel-efficient cars, and those who purchase the fuel efficient cars are in a sense subsidizing the sales of pickup trucks. The Sportwagens have been labeled as "polluters" and are required to have complicated and expensive emission systems to meet some arbitrary NOx numbers. Gasoline powered trucks, nope.
What kind of system is this? This isn't a democrat vs. republican thing - if the administration is serious about pollution, be serious about it, don't set up a paper swiss cheese system. Otherwise, just get out of the way and stop punishing the wrong people.
LDT4 emissions are ~4x LDV/LDT1 emissions, which is bad, but they aren't VW with emissions cheat enabled bad (~5x-35x).My neighbor, who drives a Prius asked me how I felt driving our Golf TDI because it pollutes so much. She said I would be better off driving my Touareg because it uses gasoline.

Passenger car and light duty truck emissions standards have been aligned for several years, with the exception being CO2 since that is tied directly to fuel consumption. A carbon tax would level the playing field for CO2, although at the expense of great squawking by pickup truck and SUV commuters.Right, this is the thing that makes me the most upset about this whole thing: the regulations are meaningless.
