2015 F150 HD Payload 5.0L vs F250 6.2L

For those who don't want to go the diesel route or are shy of turbos (Ecoboost) I'm wondering how these two 2015 vehicles would stack up to each other towing a 25' 7300lb Airstream?

F150 with HD Payload and Max Trailer, SuperCrew, 157" wb with the 5.0L engine. Payload 2660lbs (real life more like 2300lbs)
385 HP at 5750 rpm
387 ft/lb at 3750 rpm
Base Curb weight 4930lbs for Supercrew 157"wb with 5.0L V8

F250 Crew Cab, 156"wb with the 6.2L. 3000lb payload
385 HP at 5500 rpm
405 ft/lbs at 4500 rpm
Base curb weight 6828lbs for Supercrew 156"wb with 6.2L V8

The engines specs seem similar and even if the 5.0L is slightly less powerful its not having to push almost 1 ton more of weight before even adding the trailer, occupants and cargo. I would hope the fuel mileage, solo and towing, would be better on the 5.0L than 6.2L. I would expect the towing performance of the 5.0L F150 to be better because of the lower curb weight of the F150 vs F250.

Wheel bases are the same so they are both stable towing platforms.
2300lbs of payload for the F150 is plenty for most towing needs. I would expect the F150 even with HD Payload to be a better ride.

When pricing out an XLT in both the F150 HD Payload and F250 are pretty closely MSRP priced however dealers in my area are discounting F250 6.2L more than F150s. Maybe that will change later on in the year.

To get an F150 with HD Payload special order is needed. F250 you might find one the lot.

Your comparison leaves out the most important specification of a towing vehicle, the rear axle ration.

All the power in the world is useless if you are allying it through area rear that was selected for Federal fuel economy standards.

The rear axle ratio you get with HD Payload on the F150 is 3.73. The F250 6.2L is 3.73.

I've done the same comparison with 2014 models. I found like you the F250 itself is much heavier.......(poorer solo mileage, higher insurance and tag?, less maneuverable). Plus I think the 6.2L requires premium fuel for rated power? The other considerations for me were a much roomier cab in most dimensions, taller bed sides, and a smoother ride for a driver in the F150. F250 advantage is payload of course.

Our '13 F150 2wd Crew 5.0 does fine with our FC 27fb. I wish I had 3.73 axle over 3.55, but it does good in the Florida mountains! 😄

If I realize the same towing performance as my Tundra with the F150 5.0L I would be happy. What mpgs do your realize towing or what is the typical towing range?

Thanks

When the Eco-Boost V-6 came out a couple of years ago, one of the truck magazines had 2 rodeo pairs try both the Eco-Boost and the 5.0 in the F-150, both with 3.73 ratios. The 2 pairs hauled a 2 horse trailer with their rodeo gear for about a month. The 5.0 average over 20 mpg towing, while the Eco-Boost was in the 16 mpg range. I used to have that article and it was posted here, but I can't find it now.

If I was towing a 28'+ AS, I would still consider the F-250 with a 4.30 rearend, especially in the mountains. My wife has a Lincoln LT, a fancy F-150 and while I have towed our AS with it, I much prefer the feel of my F-250 when towing.

Pfft..... 16 nor 20, neither possible towing much with an F150 I know anything about. My 5.0 w/3.55 2wd "might" get 21 empty w/cruise set and air off downhill! 😊

Seriously though I get like 17.5 avg doing pretty much anything unloaded and maybe 14 towing our 27fb in the previously mentioned Florida mountains (you know, overpasses).

What I have found recently that I couldn't believe but it's true is that Plus grade fuel helps. I have better towing performance and less downshifting with it (I run in 5th gear anyhow).

I run my Tundra in 5th too and mileage doesn't seem to suffer bit I've never got 14 mpg hand calculated. HD Payload restricts you to 3.73 .Apparently Ford is not even building HD Payload packaged F150s yet. Probably make a decision in late summer.

Most of what I've read is Ford recommend premium when towing. Premium is 20 cents cheaper than diesel in our area. It almost makes the case for diesel.

That HD payload is one of the reasons I skipped Ford, if you want to save the depreciation hit buying used, you'll be looking high and low all over to find one.

And yeah, I'm with ShinyPete on Pappy's 20mpg statement. I'm sorry, but you are terribly mistaken in your misquote. Please provide a source because there is no way an F150 5.0L or Ecoboost is doing 20MPG towing.

If you want to read about the reality of someone's MPG with an ecoboost and a 28ft Airstream, I present you this source: Towing gas mileage | glamourstream

Those guys haul a** while towing. No wonder they have low mpgs. Can your really tow Wolf Creek Pass at 70mph? I haven't been on that stretch of highway for a while.

They must have a heavy foot running solo too.

I tow at around 60mph and solo, drive the speed limits. I haven't hit any 75mph speed limit roads yet driving solo.

I think what my research is showing the towing power of the 2015 F150 5.0L and F250 6.2L will be about the same due to the additional weight of the F250. Towing MPGs may be about the same but solo mpg would be a little better on the F150. Comfort and ride may be better on the F150 despite the HD Payload.

I checked Fuelly.com for 2015 averages. The best averages.

F250
6.2L 15.4 average, 16.7 best
6.7L diesel 17.6 average, 19.0 best

F150
5.0L 16.4 average, 17.1 best
3.5L EB 16.4 average, 17.2 best

Tundra 2010 (my model year)
5.7L 16.8 average, 17.9 best

KJRichie, I'm curious, what's your reluctance to the eco boost? More torque = more tow. The Eco boost has been out several years now and seems to be a proven engine.

I can't add much to your non eco comparison but I am pleased with the towing capability of my 2012 F-150 crew 4x4 Eco boost with HD package (not max). The past fall I pulled our 27' Flying Cloud from Oklahoma, to SD, Wy, CO, AZ and back home. 19 days and 3331 miles in all. I used 263 gal of gas with an MPG average of 12.66. Although most was actual towing I did unhook a couple of times to run around without the trailer. I had no problems towing with the Eco Boost. My non towing MPG here in Okla is around 18. I don't use premium gas but when in Okla it's easy to obtain 100% gas instead of the 10% ethanol in most states. If I had a 2x4 instead of a 4x4 I suspect I would come closer to 20 non towing. When towing I try to keep my speed at 60 although I often catch myself creeping closer to 65.

Hopes this helps a little.

-Wes-

Interestingly, Ford are tooling up more production facilities with 3 centers producing F-Series in the near future - Kentucky, Dearborn and Kansas. Good news for the economy?

This article gives a hint that the F-250 may soon have a new Alu-alloy body like the F-150. I'm guessing with perhaps 800lb weight saving. I look forward to the inevitable debates when this is released.

I found this article. Chevy 6.2L, GMC 6.7L, Ram 5.7L, Tundra 5.7L and Ford 5.0L

2015 Light-Duty V-8 Challenge: Overview - PickupTrucks.com Special Reports

The F150 with 5.0L scored well in all the tests and achieved an overall 3rd place overall rating behind the 6.2L GM trucks.

Correction. 12 I should have said around 12 mpg towing our 27fb, not 14. I'm better on a real keyboard than a touchscreen. Still, I'm very happy with the 5.0 "coyote" V8 from Ford.

When it debuted in the 2010 Mustang GT, it was all that and a bag of chips. It's "detuned" in the truck versus the GT and when mine is out of warranty in the fall I will most likely put in a programmer with custom towing tunes for various grades of fuel. Supposedly that really unlocks the potential of this engine.............
