Ford's 2003 light truck Powertrain lineup
published: 25 February 2000

date of revision: none

source: internal Ford Motor Company documents



Planned program changes and enhancements:

* An all new 5.4L 3V engine will be used in the F-Series and Expedition replacing the 5.4L 2V
engine.

* An all new 5R100W automatic transmission will replace the 4R100.

* Ford will upgrade the 4R75W to the 4R70W for 5.4L 3V powered F-150's and Expeditions.

* An all new 4.5L Navistar diesel will appear <details>

* An all new R4 manual transmission is scheduled; however, engineering problems might cause its
delay or cancellation <details>



Power increases:

4.2L V6 will utilize mechanical returnless fuel system. 210hp, 260ft-lbs. torque

4.6L 2V will carry forward from U222 with 240hp, 295ft-lbs. torque, IAFM mechanical returnless
fuel system. This engine will be shared between the F150 and Expedition only.

5.4L 3V will feature VCT, dual spark plugs, IAFM, ETC with torque based shift, electronic
returnless fuel system. 305-325hp, 365-385ft-lbs. torque. It will be mated to a 4R75W when used
in the Expedition and to a 4R75W or a 5R100W when used in an F150.

5.4L 3V bi-fuel is another new engine with the same modifications as the 5.4L 3V but can be used
with leaded fuel, NGV as required. It will be mated to a 4R75W transmission when used in an
Expedition and either a 4R75W or 5R100W when used in an F150.

5.4L 4V will be modified for increased output. Horsepower will jump to 325 and 355ft-lbs. of
torque. It will only be used in the Navagator and Blackwood and will feature ETC with torque
based shifting, electronic returnless fuel system and a 5R100W transmission.

I like what I'm seeing here. Those seem like very big HP jumps. I may just keep my 98 and wait out the 2003. Forget buying a 2001, I need more more horses.

Ive read this quite a while ago, and it does seem interesting. Cant wait for that killer 5.4l and 4.6l to jump off the line in 2003!

 

I really like the 5.4L numbers! Looks like I might be trading up again!!

305-325 HP STOCK for an F-150...nice!

------------------
2000 F-150 XLT, 4x2, 5.4L Supercab, Styleside, Black with silver two-tone, 3.55, class III towing package with heavy duty cooling package, 4 wheel disk ABS, overhead console, sliding rear window, keyless entry, dark graphite interior, in dash CD, Pendaliner bedliner, K&N air filter, rubberized undercoating, cabin filtration system, Bugflector II, 5W-30 Mobil 1, engine build 10/4/99

 

I think those figures are somewhere "near" today's Lightning's figures...

Hmmm...

 

Was there any mention of the 6.8 upgrades? I guess I could look, but if anyone already saw it

 

Cool all I need now is a flux capacitor in my truck, so I can go back to the future, and get me one of them trucks now.

I hope to be able to buy a new truck by 2003 if not it will be my next used truck in 2005

AAAAAAAAAAAAWWW! You mean I have to wait 3 MORE YEARS for a new truck? Dangit! I was looking to order one in a few years. Guess I'll wait.

p.s. Is it the intake or the exhuast that gets an additional valve?

 

Mike Lewis,

Yeah they are, but the thing is, the Lightning is getting upgraded to 400hp for the 2001.5 Lightnings.

What's this mechanical returnless fuel system....cause right now I'm having problems with mine and need to replace it and if this thing does anything for power then....

A returnless fuel system looks like an interesting idea. The present FI systems use a "shunt" regulator. It takes fuel at a higher pressure, bleeds off what it doesn't need at the moment, to a return line. So all the costs of the fuel return system are there. In contrast,a series regulator would deliver the fuel pressure needed at the moment, but without a return line. Sounds like they may be figuring out how to design a series regulator that also uses engine vacuum as one of its inputs. Would think that cost is the driving factor to make this work.
Any idea what "IAFM" stands for?

 

The new power numbers confuse me. I remember talking about the 5.4 2V and the 5.4 4V a few months back. It was stated that Ford puts the 4V in the Navigator to differentiate itself from the F-series trucks by giving the
4V version significantly more power (understandable). Why not just put the 4V version into the F-series...the power numbers will be very close.

Engine Horsepower Torque

5.4 (3V) 305-325 365-385
5.4 (4V) 325 355

Why waste your time engineering a new engine when the performance numbers are so close?

I am also disappointed with the 4.6 liter performance gains. Since it's introduction, they have increased HP by 13% (taking 2003 numbers). The 5.4 liter has increased a minimum of 23% (once again, using 2003 numbers). The 4.6 liter is a good engine and I would like to see it get more respect, but its hard if they don't want to give it too many performance upgrades.

 

The 3 valves/cylinder engine will probably be cheaper to make than the 4 valve/cylinder.

Pastmaster - motorcycle engines with 3 valve/cylinder have 2 intake valves and one exhaust valve.

 

Dfolk,

Ditto. If Ford can make a 305 hp 4.6l, they can atleast upgrade the 4.6l in the truck.
