Not really surprising. The 3.5LGTDI has a *ton* of power. You put your foot into it and it is a rocket. Kind of addicting... And definitely not good for fuel mileage.

I think of it more like having the performance of the 6.2L (arguably better) and the fuel economy of the 5.0L (again, better).

If you're trying to decide just drive both. They are very different and the decision should be easy. I am one of many who thought I'd get a v8 hands down until I drove one. They sell themselves.

At least with the ecoboost you have a shot at good MPG and the price is about the same as the 5.0. Its easy to get 10k off MSRP for either.

I honestly would get the EB in your situation. Believe it or not i would also get the 3.55. This coming from someone with the 5.0 and 3.73 ELD. I love my setup but if you want MPG strictly get the EB with a 3.55 or lower diff. You will get the best mpg with that setup. If you have a 5.0 you should be able to see 17-19 mpg regularly out of the 5.0 assuming 55-70 hwy speeds (flat land in Iowa also). I see 16-17 mixed driving in my 5.0 with 3.73 and usually 19-21 on the highway if its strictly a road trip. Hope this helps.

Of all things are equal (gears, tires, truck configuration etc) the mileage difference between the two is not worth any thought. Drive them both (equal as in above) then decide which motor you like driving better. Then decide what truck you want it in.
I'm an Ecoboost owner and I'd have a 5.0 in a second if I didn't love mine so much.

You have obviously been cruising the web when you say you've noticed that EB mpg figures are all over the map. I'm one of the lucky ones who gets reasonable mileage with his EB. A lot of people complain about the EB mileage. A LOT!

Having said that, the V8 posts rarely complain about gas mileage; gas mileage comments on the 5 liter engine are all positive!

Youtube f150 0-60 and view the many short vids of the V8 and the EB - there's not much difference! Maybe that'll help with your decision.

Lucky you: no matter which engine you go with, you win!

Warning: Contrarian here.

Why buy a truck at all if you don't need it to haul or carry something? The VW CC is a good vehicle, no? With good snow tires, traction control and front wheel drive, you should be able to handle most anything but real deep snow. My VW Passat is great in the snow and ice.

Part-time 4 wheel drive found in most trucks only works well under slippery conditions: heavy snow or off-road. Partial/light snow/ice on pavement will over-heat and eventually burn-out the transfer case as the wheels can't slip. They don't have a centre differential like the Torsen.

So ya, if it's deep snow (and steep icy hills) you're worried about, then a 4x4 F150 with the right tires should help. But so would a full-time AWD Suburu, or VW Touareg with 4-Motion (AWD), or Audi Quattro (although only the SUV's will have similar ground clearance to the truck). And these full-time AWD vehicles with a centre differential can handle partial/light snow/ice on pavement as well.

Me, I'm retired, so I just stay home until the snow plow comes by and then get out the snow blower to clear the driveway of deep snow. Got to do that eventually anyway. My 2WD vehicles with snow tires work fine then after a real dump.

Or I go to Florida. Actually that's the best solution, and your VW CC would be a great cruiser for heading South!

I like to modify vehicles to..another reason I went with the ecoboost. Seeing how many rwhp you can add to most turbo vehicles with a tune only and better gas mileage to boot. Heck a tune/dp eco already made 90rwhp more! I forsee a good amount of power coming out of this TT motor.
