Will Ford put a 4.4 liter V8 diesel or a Ecoboost in the Expedition and Navigator?

 

Not in 2011

 

I heard Ford was supposed to that. I even saw spy pics of a diesel. I guess that's not on the horizon any more.

 

No diesel for 11.

 

I've got to think an EcoBoost with more hp/torque than the venerable 5.4 and a diesel option with both be compelling options to sophisticated buyers. C'mon Ford!

 

I don't think the SHO motor as it stands today would work well in an Expedition. While it works well in a 3500lb Taurus, a 6000 Expedition is a different animal. Just not enough torque off idle to move it, the Ecoboost motor would need to be spooled up and making boost just off idle and all the time (like a diesel) to be a performer.

 

This argument/request has been going on since 1997. So 14 years later, no diesel.

 

Hopefully whenever they restyle the Expedition and Navigator for 2012 or 2013 Ford will put some fuel efficient engines in it.

 

Yeah, and a tranny that is flawless, leather that doesn't wear, paint that doesn't bubble, Fuel gauges that work correctly, etc.

 

That's just a dream.
I'm considering a turbo V8 Cat with an Allison for my 2000 Navigator after I decide on the frame and suspension mods needed. This might also be just a dream.

 

I know. As time goes on the Expy becomes more fragile as Ford finds more ways to save bucks.

 

2 more weeks!

and repeat as neccessary.

 

Maybe they might unveil a new one at any of the major auto shows next year. I am in the market for one but I am realizing the technology is really old. It's needs a reskin, badly. I'm upset that Ford puts those crappy plastic running boards on those Eddie Bauers and XLTs. It needs stepbars or fiberglass running boards. Something that is better quality and durability. It's a truck. It should have the durable features the F-150 has.

 

the 2005-2006 navigators zf auto 6 speed transmission is very reliable.

 

I haven't driven a new SHO first hand, but I think you're describing the SHO from years ago. My '91 & '95s came alive at 4,000 rpms which, as you said, wouldn't help much in an SUV.

But the new torque "curve" really isn't a curve at all. It peaks under 2,000 rpms and stays up there for a long time. We have a BMW with a twin-turbo Six that's pretty similar and it pulls like a 5.0 Mustang, even from 1500 rpms.
