The Eco Boost is a pretty cool engine when it suits the needs. It has plenty of power and gets good in town mileage. This engines biggest downfall is bigger tires. Like everyone says it is very powerful and efficient when it has boost. When you are putting around town or cruising down the highway you are using minimal boost if any at all. I've seen multiple vehicles attempt 33inch tires on and mileage drops to 11 constantly in town and 14MPG. Changing out gears would be one way to get that back. I have seen multiple people trade in the 3.5 for a 6.2 just because the bad mileage when tire size is increase. Just my opinion on what I see everyday working with them.

I would agree to that but that is not always close to true. The truck plays a major part. I speak from experience with my 2004 F150 FX4 SCrew. I bought new in '03. it was rated for 14 city / 18 highway.

I drove it the same as I do this one. i NEVER saw better than 13.5 on the highway. I would get 10-11 in the city.

So I would disagree that if I drive my vehicles the same they would react the same. At a little over a mph difference, I would never take the chance. My luck the EcoBoost would get 17 or less!

that again is another variable that isn't really a fair match up to toss in there. Different truck completely, different trans, less gears, different gearing rear, smaller tires, less weight, yadda yadda yadda. Going with the identical everything other than the engine, the assumption that if you can drive and get better mpg than sticker on one motor, you're likely to see a higher mpg than sticker on another motor as well. Not necessarily the same exact amount, but Ford does do the same testing and ratings for fuel economy on the same configuration trucks, and if you're getting higher than their rating on that configuration with 1 motor, you're likely to get higher than their rating on that configuration with another motor.

A dyno chart of the 6.2 (non raptor) and 3.5EB would give you an idea too. The 6.2 has tons of power everywhere thanks to it being naturally aspirated. The EB only has a bunch of power when on boost. Being turbo'd, the power is all high up. So unless your on boost, the lack of power may cause low fuel mileage.
Just a thought.

I wouldn't go and say it's tons of power everywhere. The torque does have more of a curve till it peaks, where the 3.5 EB torque curve is more of a table and peaks at a low RPM and sustains that tq throughout the powerband. With how small the turbos are and being two of them they spool pretty fast to be in boost whenever you want. Driving the truck on the road there's very little lag.

It's only a fair for the mileage comparison that if you're adding the larger tires to raptor sizes, to change the gearing to raptor gearing, otherwise the mpg arguements are skewed with only changing half of that. It's the same as going and putting 3.08's or 3.55's in the Raptor and griping the fuel mileage around town went to crap and the 6.2 sucks. It's not the 6.2, it's the gearing. Find results where an EB owner did tires AND gears and it'd be a much more even comparison.

No, the comparison is preposterous. You don't buy a 4x4 for fuel economy, you buy it for capability. Any discussion of 4x4 or even truck mpg is as stupid as discussing whether a Prius is faster than a Honda INSiGHT or a Ford Leaf. If you've bought a Raptor and you figure mpg at every fill-up, you have bought the wrong vehicle because you don't know your own mind.

If you like action-adventure, don't watch Opra.
If admire the brainy type, then don't bother trying to score a date with Megan Fox.
And if fuel economy is your primary automotive concern, then don't buy a 6,000 pound, 411 bhp, 4x4 truck.

When somebody asks me what kind of gas mileage I get with my Raptor, my standard response is, "What a peculiar question!" Because it is.

Now wait, gas mileage isn't my primary concern but i sure as hell would love to get better mileage. Who doesn't want to go to the pump less. I'm not talking about pussifying the Raptor but if they offered one with the same stats that got 25 mpg I would sure as he'll buy that one. Nobody wants to pay more money than they have to. And to say that gas mileage shouldn't be a concern at all on a truck is just obsurd.

One thing that hurts our 6.2 is the comparatively low compression. We would get at least a 2mpg bump if we were running 10.6 vice stock IMO. To appeal to a broader audience, Ford designed the Raptor to run on any octane.

I was disappointed to learn of the valve clearance issues with the XT/R cams as my first engine mod was going to be cams and milled/ported heads.

Keep your head burried in the ground. But if you could care less if your truck got 5 mpg or 35 mpg, then all I can say is it must be nice to have zero money concerns, and there must be some perks to visiting the gas station so frequently that I've never discovered before because I personally can't stand going out of my way to fuel up all the time.

Your analogy to saying it's just as stupid to want to know if a leaf or prius or insight is faster than one another is equally as ignorant. Even those those buyers are more concerned with mpg as a top priority, there's nothing peculiar at all with wanting the faster of the gas sippers. No different with our trucks. Why want a big powerful fast engine on a truck thats not meant for drag racing? Why? Because you can have more than one criteria when looking for features in a vehicle.

If you bought a raptor and you figure mpg at every fillup, has nothing to do with buying the wrong vehicle, what you USE the truck for dictates if it's the right vehicle for you. What you SPEND on fuel has nothing to do with offroading, hauling, towing, etc. It has to do with not being happy with throwing money at the pump.

I don't think ANYBODY on here is saying they wished ford put smaller tires, or lesser aggressive flared fenders, or less hp to get better mileage in their Raptor. NOBODY is saying they wish their raptor was designed more prius-like. Take away the ignorance and you'll understand the viewpoints on it'd be nice if more technology was done to keep what we've got, and improve mileage. And no it's not impossible. Just look at the 5.0's. The old pushrod 5.0's the cars weighed less, had way less power, and crappier fuel economy. The new 5.0's the cars are heavier, have way more power, gobs of modding potential, and better fuel economy. You can have your cake and eat it too.

But hey, keep on doing your thing...

EXACTLY! x1000000000000000000000000. Somebody who gets it.

I've got a feeling that the 5.8 that Ford is developing for the 2013 GT500 will make it's way into the trucks and replace the 6.2. The 6.2 is more closely related in design to the 5.4 and 4.6 that went to the glue factory. I'm pretty sure the 5.8 is going to be more similar in design to the 5.0 as a big brother engine. It'll fit too, so it wouldn't be a big change for Ford to move it into the trucks, since the trucks fit the 5.4, and the GT500 now has the 5.4, goes with a pretty safe bet the 5.8 will swap in to the trucks as well. Just think about the potential, a higher compression N/A 5.8 4 valve similar to the 5.0 for the trucks, it should easily surpass the 6.2 numbers in power and fuel economy. Then coupled with a blower for the GT500's an easy 600+ hp. Sounds like a recipe for a Gen 3 Lightning as well.
