I was sitting at a stoplight across from a new f150 and when he passed me it said sfe on the bed what package is that? someday im going to upgrade to a screw (fx2) but it looked pretty good just in passing

 

its suppose to get really good gas mileage

here is a link http://www.autospies.com/news/2009-Ford-F150-SFE-34918/

 

hmm i think ill pass on this it looks like to me its just a high geared rear end with a six speed.

ill wait for the fx2

 

ya nothing to fancy about it
the 2010 FX2 and Harley F150 look sick

 

superior fuel efficiency

 

It's just a marketing thing. It was dropped as a trim level for 2010 because all 2WD 4.6L with 3.08 axle are rated for 21mpg highway.

 

SFE 9.75 rear end is 3.15, not sure about the 8.8 rear end.

 

Doh! 3.08 is gone for MY09. 3.15 for both 2wd 3v 4.6L and 5.4L 6-spd combos.

 

Lower gears and low rolling resistance tires.

Means you can't tow worth a damn and you can't get off pavement without getting stuck. If you ride the highway a lot and have to have a truck then buy it, if not then pass. Its just a way for Ford to get there fleet avg a little higher.

 

my 04 4wd with stock wheels & tires and my modifications got 15 - 16 city and 20.4mpg highway, and with a 4spd 3.73....

 

That's the truck you want to pass on

 

The gearing of the 6-spd first 4 gears with 3.15 axle ratio are shorter than all 4 gears of the 4-spd with 4.10 axle ratio. It's like a 2004-2008 truck with two even taller overdrives, which I thin is a little worthless as they cannot hold 70mph at 1500rpm on anything but flat and downhills. Any overpass will cause downshifts.

People with 3.55 and 3.73 axle ratio with this new 6-speed are getting up to the same FE as the EPA rates the SFE, with 18% more torque at the wheels. I see no reason not to get the shortest axle ratio with the 6-spd. And the payload issues would only let me pick the max tow package with 3.73 axle ratio.
