It would be better if it was a 5.8 based on the 5.0.

 

That's what I was thinking. 4.0 EB V6, or 4.5 EB V8.

 

I think a 4.5L V8 EB would be PERFECT in the Super Duty!

 

If I'm not mistaken the CAFE standards are going to start applying to the super duty. If that is true then Ford needs to get a very fuel efficient motor in the lineup to even things out. That doesn't necessarily mean big power or towing

 

I highly doubt ANY gasoline engines will be offered in the HD class for 2019. That includes the entire Big 3.
The 3.5 EB is not better on fuel than a V-8 gasser. A 4.5 EB would be a pig.

Expect two diesel offerings from Ford.
One smaller V-8, and a V-6.
Fuel mileage must be better, and the HD line must still maintain some torque for commercial use.

 

There WILL be gas engines available in the big 3. Diesels are too expensive and costly for some people and none of the big 3 will do away with gassers completely in the 3/4+ trucks. Won't happen.

The 3.5EB DOES do better on fuel than a V8. You need to compare the 3.5L to the 6.2L (which is no longer available in the F150) to get a comparison since those two had similar torque and towing numbers. The ratings (and real world numbers) for the 3.5L were several MPG better than the 6.2L. The 3.5 matches closely with the 5.0, but has more torque and tows much better. To compare fuel economy, you need to compare apples to apples.

A 4.5L EB would suck fuel while towing, and likely get similar towing fuel economy to the 6.2L, but it would tow MUCH better with a much flatter torque curve, and likely get an extra MPG or 2 while empty over the 6.2L.

 

Remember the epa doesn't care about real world mpg. All they care about is doing circles on a test track at 55 mph. A 3.5 or 4.5 EB will blow the 6.2 out of the water on that kind of test. Even the 2.7 would do awesome on that sort of test in a super duty.

 

That's a little narrow-minded, don't ya think? How do YOU measure real-wold fuel economy? Do you think it's how I would measure it? Probably not, that's why comparing fuel economy on an internet forum is pointless. Everyone's conditions and driving styles are different.

The only objective way to measure economy is with a common standard applied to everything. Which is, like it or hate it, exactly what the EPA does for fuel economy testing.

 

That's exactly my point with people saying a 3.5 EB wouldn't be better in a super duty. It all depends on how it's used. The heaviest f150 is the same weight as the lightest super duty so why wouldn't it work.

 

Honestly I think it will be more likely the diesels are gone........

 

I completely agree. I remember a few years ago the Excursion forum folks were telling me that the EcoBoost wouldn't do any better than the V10 because it would be working hard. But my F150 got better mileage towing the boat(Combined 9,300 lbs) than the Excursion(7,350 lbs) ever got empty.

 

My 3v 5.4 F350 will out pull my v10 excursion any day of the week with any load. I definitely understand where you are coming from

 

Exactly. There's a reason the Raptor and the new GT both have modified 3.5TT's. The SD is next IMO, and go ahead and rate the max tow option to around 12k or so, I would want it, and many others too. The gas SD's of 2000 5.4/6.8 were rated in F250 at 7400/10000. I remember the 5.4 in SD's back in '99 with the new body, and it worked for many folks. As said, I think the F250 is subject to fuel economy standards soon. The 3.5TT and even the 5.0 blow that motor away.

 

I would like to think that you are right.
But with the current release of smaller Diesel engines in the light trucks, and rumored in the new redesigned Jeep Wrangler coming, the future of fuel efficiency points to diesel IMHO. Diesel will offer the best fuel mileage/torque ratios.
I'm no Nostradamus, but I think the future shows itself sooner rather than later.

 

I hear you on the diesel winning the "Est.MPG bs" , But around here, no one even talks about the Eco-Diesel anymore and in fact it is generally frowned upon. There was hype for the "half ton diesel" but I feel it was short lived, at least in the Ram. However, this is my small sample size of where I live.
