Hmmm . As I recall in the 2007 pickuptruck.com 3/4 ton shootout, the F250 V10 weighed 1000lbs more than a Sierra 2500 6.0L gasser. So your sayin then that the F150 wieghs 400-500 lbs more than a Gm 2500 gasser? Or were you not including the V10 in your debate?

And re fuel mileage... Some of the better mpg I've pulled with my F150 on long trips... I just don't think a F250/5.4 would pull them off. Infact I know they wouldn't.

Were you comparing 6.5bx to 6.5 bx? or 6.5 250 to 5.5 150?

yeah, I replied to fonefiddy in a PM, trying to not derail the thread....but I looked it up and the comparable F250 to my current truck, CC 4x4 6.5 bed, weighs 6700 lbs, as opposed to the 5,600 for my F150.

So in order to get comparable towing performance I'd need the bigger engine, which drinks lots more gas.

I really want to see the torque curve on these engines, and know if the blocks are aluminum or cast iron, don't really like aluminum, don't think it would hold up that well in the long run.

I compared an 09 F150 5.4 crew 6.5 max payload@ 5880lbs against a 09 F250 5.4 Crew 6.5 @ 6480lbs. Numbers off Motor Trends site

Give or take a few options, and they weigh within 500-600 lbs of each other

same motor in 150 and 250, but that tourqshift tranny in the 250 does wonders when towing

PickupTruck.Com - Part 1: 2007 PickupTruck.com Heavy Duty Shootout

curb weight of F250 w/V10 = 7,600lbs so even if you discount extra weight of V10 vs V8, ist still min 1000lbs heavier than a F150.

The 5.0 in the Mustang will almost certainly be aluminum. Thats pretty much a given. I have no idea about the F150 version. Im also interested to see the torque curves. You can bet your hind end that as soon as one hits the streets in a stang somebody will drive out of a dealership straight to the drag strip and dyno to ring one out.

Lets hope we are all not let down here. Ford has really improved just about everywhere except engines and they had better bring their "A" game this time around. I have given them the benefit of the doubt in the past but not anymore and Im a Mustang owner as well.

I would really like to see some answers before it is too late to get the 5.4 if I don't like what I am seeing.

The CAFE standards have nothing to do with how many vehicles You sell. It takes the AVERAGE Fuel Economy of every vehicle You produce.
If Ford builds a 60 mpg vehicle in enough volume to qualify as a production vehicle. Then they'll be able to continue offering 16 MPG trucks, without paying the CAFE fines.

Has anyone actually calculated what Ford's overall average MPG's are? I'm sure someone has an idea if they have to meet a corporate minimum MPG by a certain date. Considering that Ford sells more Expy's and F-series than anything else, I'll assume they're probably playing catch-up with GM and possibly Chrysler. The Fiesta and the Fusion Hybrid will def. help.

Fords CAFE in '07 was 28.8 MPG

The new (2011??) standards are shooting for 35 MPG

Here's an interesting read concerning Cafe

Thanks for the link! Needless to say I didn't read all 315 pages but I got the gist of it. I don't see how 35 is doable in the light truck segment. Also, I didn't notice the study separating SUV's from pick-up trucks. I may have missed that. They seemed to blanket a GVWR vs. a body style. With that assumption, Ford would need to build a helluva lot of Escape Hybrids.

How do the crossover SUV's get accounted for in this study?
