2005 F-250 DRAG COEFFICIENT

Does anyone know what the drag coefficient of the f250 is? Or where to find the literature on it? Please no smart azz remarks like barn door or brick or boat anchor. I know its high I just want to know what the round about figure would be.

According to this, a 2012 is 0.45 to 0.425Cd
2012 Ford Super Duty | Folsom
A brick is more like 2.1Cd. so a superduty is way more aerodynamic than a brick.

The current trucks are around .45

Cant find anything on our older trucks.

How close do you think they are in comparison to one another?

It's funny you posted this, a buddy and I were talking about this the other night, after a 60 mile drive straight into a pretty bad head wind. He has a 2009 and his milage dropped about 1.5 and my 2006 only dropped 1.1. I know this means nothing but from looking at both trucks side by side, they 08+ frontend looks quite a bit bigger. We also looked for the drag coefficient of both trucks and could only find the 2012 specs.

Any how I think the 05-07 should be lower than the newer trucks. I could be completely wrong to.

I wouldn't consider the mileage drop too closely, in fact I would have expected a 2009 to drop even more to be honesty given its already a huge fuel hog compared to the 6.0. Having said that I do agree the 2003-2007's do "look" a hell of alot more aerodynamic.
