Yeah I get it. I understand the desire for better gas mileage. I get an avg of 13 between city and hwy and that w/o a lift or big tires either I accept that for now.

There are a few people on this site who just love to tell others looking for help that the 5.4 is absolute crap. They pass the info off as fact. It is only opinion and I want to ensure, especially to the OP that it is indeed only opinion.

And like you I like the interiors. The interior of my friends' FX2s, FX4s, and my Plat is absolutely freakin, hands down better than an others I've seen in a factory truck. Cheers.

 

I would hope someone would select the 5.0 for reasons other than gas mileage alone. I mean how much real world difference is there really going to be between the 5.4 and the 5.0 anyway, a mile or two per gallon. I'm averaging between 15.8 and 16.0 this winter in Minnesota and in the summer I avg. 18-19 with my 5.4, so I have no real complaints there.

I certainly wouldn't trade my 09 on it and lose my **** just to get slightly better mileage and maybe slightly more power. If on the other hand I was trading in my older high mileage truck and was deciding on whether to buy a 2010 with all of the remaining incentives or pay much more for the 2011... Personally, I would have to pony up and go Ecoboost. I think if gas mileage and or power is going to be your strongest deciding factor why settle for the 5.0 when the EB does everything better.

But that's just me..

 

I'll be glad when the 2011's have been out for a while so the topics start to change... OP, buy whatever the hell you want. I have had two 3V 5.4L, I don't tow anything, never really haul anything in the bed, I just like driving a good looking truck, and being comfortable. Performance is cool, but at the end of the day comfort is the most important thing to me. Getting in and out of a sedan is a b*tch.

IMO, give it more time and see if the EcoBoost proves itself and get that motor. Goodluck with whatever you buy, I am sure you will be happy with either motor.

Cub, if you don't like the Ford Interiors, then I guess you will stick with your current truck, because IMO Ford by far has the nicest interiors esp in the higher end lines. The only truck that comes close is a Denali Sierra.

 

Smart Man.

 

X2 and the 5.0L is pretty much the same motor as in the Mustang. All they did was drop the comp by half a point, changed valve timing to change the torque curve for truck app. and cast manifolds once again for truck app. So if you like to mod this engine is going to be a beast. theres some guys doing some amazing things with this engine. cant wait to see what the aftermarket is going to come out with.

 

I had a chance to buy both a 2010 or a 2011. I was really disappointed in the lack of power that the new 4 Valve 5.0L had compared to my 2008 Sport Trac 4.6L 3 Valve with it's 6 Speed 6R60 and the 2010 F150 5.4L with it's 6R80 6 speed transmission. Both trucks in Crew Cab 4WD drive trim.

While all the boy racers love the high rpm power the 5.0L has, which is better than the much lighter Sport Trac and the 2010 5.4L, the 5.0L does not offer as much power in the normal driving rpms. The 5.4L in comparison is a torque monster next to the 5.0L where you have to wait and wait for the power to finally come in.

The 5.4L has been proven for a very long time. The completely new 5.0L 4 Valve engine has no maturity under it's belt and any owner will be the new engines guinea pig.

By comparison, the 5.4L tow rating with a 3.55 gear axle is 9600 lbs while the 5.0L is only 7700 lbs!! Now put the 5.0L with a 3.73 and it's rating goes up to 9300 lbs, still 300 lbs shy of the 5.4L with worse gearing. Now put that 5.4L with a 3.73 with beefed up components and you'll have 11,300 lbs tow rating. That is with the Max tow package. The 5.0L is not even offered with the Max tow package. The 5.4L replacement is the torqueier 3.5L twin turbo Ecoboost engine.

Also the transmission in the 5.4L is smooth and percise. The 5.0L transmission has new programming and a new clutch. It was chugging back and forth badly while driving in first gear in the parking lot. The 5.4L transmission was smooth as butter. Obviously the 5.0L transmission needs to have some programming updates or hardware updates to get it as smooth. While the same mechanical components except for the clutch, the programming and electronics are new.

Remember the 5.0L was not meant to replace the torquey 5.4L but the 4.6L 3 Valve. The Ecoboost is to replace the 5.4L engine. The 3.7L V6 replaces the 4.6L 2 valve and the new 6.2L is all new and replaces nothing.

I went with the 2010 because I want a truck motor to act like a truck motor, with high torque on demand at low and mid rpms, not with a car motor where all the power is made in the high rpms. I use my truck as a daily driver and to tow my trailer, I don't race it to get it up in the high rpms where the 5.0L power finally comes in.

Now don't get me wrong, there is power in the low and mid rpms from the 5.0L but it's no better than the 4.6L 3 valve (when in a comparable F150).

IMO, you can't go wrong with either, just don't expect a lot of grunt and instant power from the 5.0L like you can from the 5.4L.

If I were to buy a 2011, I would had bought it with the Ecoboost engine. It is only a $750 option and you'll have a lot more torque at low rpms and you'll have 5 more horsepower and 40 lbs more torque! This engine is also uses the 3.55 axle (just like 5.4L) to get it's 9600 lbs tow rating or the 3.73 axle for the Max Tow Package rating of 11,300 lbs.

IMO, either the 2010 5.4L or the 2011 Ecoboost are the best builds.

Just my opinion from test driving a 2010 Screw 4X4 XLT 5.4L 3.55 LS axle, 2011 Screw 4X4 XLT 5.0L 3.55 LS Axle, 2010 Scab 4X4 XLT 4.6L 3 Valve 3.55 LS axle, and my previous 2008 Crew Cab Sport Trac with 4.6L 3 Valve 6 speed Trans 3.55 Axle (truck is 700 lbs lighter than my 2010 Screw 5.4L).

Also 2010s had a $6,500 rebate while 2011s only had a $2,500 rebate. Trucks have a depreciation difference of $2000 between a newest year and a left over year when both have the same miles. Research this on several models and found my information. So you'll actually gain $2,000 with a 2010 model.

 

5.0 has 360 hp@5500/380 ft.lbs@4250
5.4 has 310 hp@5000/360 ft.lbs@3500

With the specs out there its clear that the new 5.0 will simply destroy the 5.4 over 4K RPMs. You have to ask yourself how will you be driving your truck? For everyday driving either engine will get the job done but the 5.0 will get slightly better mileage. If you plan on towing the 5.4 may make a little more torque down low. The 5.0 makes more power but you will have to keep that motor revved up where as the 5.4 makes the its power down low. Personally my truck will vary rarely see anything above 4500RPMs and that's only when passing. While towing a trailer the max ill turn is around 4k under normal driving conditions. If your more into performance then get the 5.0 you will be much happier, the 5.4 lacks power up top.

If we were talking sports cars here I would say 5.0 all the way. Since were talking trucks here you have to break it down for what you will be using it for. Everyday driving advantage 5.0. Max towing I have to give the advantage to the 5.4 because you will have to be revving the crap out of the 5.0 to stay in its power band. Max performance advantage 5.0.

If we were talking ecoboost then that motor will blow both of these away. Its not all about peak numbers, its all about where in the power band a truck has its power. In a truck you want lots of torque and the 5.4 will give you more off the line than the 5.0 and the Ecoboost makes tons of torque down low from the turbos.

 

Has anybody found torque curves for both engine to compare.

 

I had about given up on this until I found a video on the web. Sorry but I don't have the URL handy. The video was taken at a ford dealer and in the showroom they had one of those cardboard displays with the torque curve of the 3.7 V6, EB and 5.0 V8 all layered on top of one another. The EB of course destroyed the other vehicles when it comes to the curve but would have destroyed the 5.4 as well.

The Ford 5.0 liter looked like it made about 315 ft/lbs at 2,000 rpm. At the time I was comparing to a 2011 Hemi Ram which put out 350 ft/lbs at the same 2,000 rpm. This weighed heavily in the Dodge's favor. For my truck I need "good enough" torque at the 2,500 range which is the highest I like to tow at steady state running and "good enough" peak hp for passing and the like. I'd estimate the new 5.0 to be putting out 330 foot pounds at 2,500 rpm which is close to the 350 my 2000 F-150 put out and matches the 330 my 1998 Ram put out but at 3,000 rpm. Also, my Dad had a 1993 F-150 that only put out 280 foot pounds at 2,500 rpm and he seemed to tow whatever he wanted just fine. And as far as passing power goes, I think we agree the 5.0 will be just fine.

So if you really are towing around 9,000 pounds you might not like the 5.0. But if I tow more than 5,000 to 6,000 I'd rather have a 3/4 ton anyway. So for me the 5.0 became good enough and who knows, maybe I can crack 20 mpg on the highway.

Did a search and found the video. Go to the 41 second mark.

Ok, explain why the 5.4 can tow more than than the 5.0. Everyone praises the 5.0 yet no one has yet to adequately explain why the tow ratings are so much less. Don't just say it's because Ford doesn't offer the max tow package with the 5.0. Even the Ecoboost has a better tow rating. If the 5.0 is so great, why doesn't Ford offer max tow with it? I don't have a problem with new technology as long as it is actually better.

 

Touche!

I'm willing to accept that the 5.4 actually might tow better than the 5.0, but it's a moot point for me considering I'm buying an EB.

I actually haven't driven a 5.0 yet - I will probably do so once I'm seriously truck shopping in a month or two, just so I know for sure that I want the EB over the 5.0...

 

no here in east tx a ford f150 xlt 5.0 4x4 is $38,000 an a ford f150 lariat 4x4 is $52,000
52,000
38,000
14,000

so there is $14,000 difference

 

That is comparing apples to oranges..,XLT to Lariat...the reason the Lariat is so much more is you are paying for that package. That is like saying an F250 costs more than an F150. If you are going to do a cost comparison, you at least need to use the same package to compare.

 

thats alright im probably going to get a chevrolet silverado 1500 6.2 for $40,000 and save $12,000 instead of paying $52,000 for a ford 6.2
