Dirty Driving: Top 10 Worst Polluters
http://autos.yahoo.com/articles/auto...orst-polluters
The Hummer H2 might be an obvious target for environmentalists, but unless it’s caked in mud, the hulking sport utility vehicle isn’t the filthiest ride on the road. That distinction goes to another SUV: the Volkswagen Touareg V10 TDI. . . . The Volkswagen Touareg V10 TDI has a carbon footprint of 12.4, which means it emits 12.4 tons of greenhouse gases annually, according to the EPA’s standard calculations based on 15,000 miles of driving per year. Burning one gallon of gasoline emits 20 pounds of carbon dioxide, the EPA says.  Is that right? One gallon of gasoline doesn't even weigh 20 pounds, how can it cause 20 pounds of carbon dioxide? Not a very good endorsement for diesel if you ask me.

Yeah I bought my Tourareg because my footprint wasn't large enough

Amazing isn't it, what a little liberal/enviro-nazi spin can do.

Just because it's a diesel, doesn't mean it pollutes excessively. I looked up the CO² emissions (I like this keyboard
 ) for the Touareg and the X5. Here's the data:VW Touareg V6 TDI: 262g/km VW Touareg V10 TDI: 333g/km VW Touareg W12 petrol: 375g/km X5 3.0sd: 216g/km X5 3.0si: 244g/km X5 4.8i: 286g/km

Recalling, hazily, my chemistry, I think the gas/diesel combustion process combines the fuel carbon atoms with the heavier oxygen atoms, (maybe 2 O atoms at at time), and thus the CO2 formed is 3 times as "heavy" coming out the exhaust pipe. I seem to recall that diesel fuel, in some trucks, pumps out nearly 30 lbs of CO2, per gallon of diesel. I have no dog in this fight...and, my "chemistry recall" and arithmetic could be slightly off the mark, but in the ballpark.
