Who has better emissions
 

I have seen a lot of information and discussion comparing the 6.7 to the 6.2 as far as MPG but what about emissions? :-rip

The 6.2L wins hands down! First they have to make five times as many parts to build a 6.7, then they have to ship it all the way from Mexico, and then you have to drive back and forth to work at least a year longer to pay for it! All kidding aside, a Diesel still produces more of the emissions that some experts allege may possibly lead to global cooling, or something like that, depending on which news channel you watch...
