Here are some of the more bad byproducts from them:
Nitrogen oxides (NOx):
Carbon monoxide (CO):
I'm all for reducing pollution, but that is not why this is being done. They are explicitly targeting CO2 because of its alleged link with global
warming (but that is another thread entirely).
These above byproducts are directly related to the level of CO2 emission.
Are they?? As fuel efficiency increases, the level of NOx increases, but IU don't see a levy on NOx, or any penalties being incurred for not reducing
130 g/km is very low indeed. Here are some CO2 figures for cars, and their engine sizes. These are the oine I just know about, but there are many
* Peugeot 107/Citroen C1/Toyota Aygo = 103 g/km. Eng = 3 cyl. 1.0 L. Seats 4, with no luggage space.
* Peugeot 206 = 165 g/km. Eng = 4 cyl. 1.4 L. Seats 5, a bit of luggage space.
No point listing other vehicles - I think you see the immediate problem. The 206 BTW can do 45 MPG easily. The 107/C1/Aygo (same car different badges)
averages 50 MPG but is very impractical.
* Peugeot 407 = 190 g/km. Eng = 6 cyl. 3.0 L diesel.
Average gas milage = 60 MPG.
So............ which car would you buy?? I'd buy the 407 - more fuel economic than the others (including the 107/C1/Aygo). Small does not mean
efficient, even if its CO2 output is higher.
