As I don't feel comfortable with doing EOC, I'd prefer having an hybrid which has been conceived to stop&start the ICE when unneeded/needed.
It will depend also on your own routes. If you do a lot of stop&start then the hybrid may be the best.
From the third document cited in the thread "
http://ecomodder.com/forum/showthrea...ions-5083.html", the CO2 numbers are the following :
- 1 liter petrol = 2.32 kg CO2
- 1 liter diesel = 2.54 kg CO2
When a prius consumes 4.3l/100 (55mpg) then a diesel has to consume only 3.9l/100 (60mpg) to not generate more CO2.
Diesel also generate particles, but these are short time; ie when not generated anymore, these disappear rather quickly : in London after a few months of city toll a lot of child had their asthma to regress.
At the other side, if a gasoline isn't well maintained it will generate CO which is rapidly converted to CO2, which takes tens of years to disappear.
We should change our car in 1-2 years. When we'll have chosen the short list, we'll certainly rent these cars to see which one we are more comfortable with. Your car must fit your needs first.
