20% improvement in fuel economy

[DaveBen]

I can't see why it would NOT drop. It is plain physics. It takes more force to more more weight in the same time frame. So if you are going down the road at 60 mph it will take more power to move more weight. Now, nobody can say how much until they test the engine.

I sometimes wonder if the morons in government who are forcing these emissions standards down our throats have ever considered the concept of reduced emissions through increased fuel economy?

If they want diesels to get 30% fewer emissions, why not build a motor that will achieve 30% better fuel economy. As it is, they are achieving better emmisions with DPF's and so on, but at what cost? How much lousier fuel economy does the 6.4 get than the 6.0 or 7.3? The result being we are nationally using more fuel to feed our "cleaner" diesels.

I totally agree

The World Oil Barons have the price per barrel jacked up, but our own EPA and Congress have had more of an impact on things than the Barons. IMO

Term Limits Anyone ??

Some sort of Intervention.. To gain some sort of "Common Sense" control of the EPA.. Anyone ??
