WHY so many new engines? Why not one or the other?

 

I think both because the 5.0 is for the mustang and f150, while the 6.2 is rumored to replace the v10 in the Superduty's, and come in limited f150 models (raptor/harley).

The 6.2 will probably be a gas hog so why put that in all of the f150 models.

 

The real reason is fuel economy standards. Originally the 6.2 was going in a lot of vehicles. Now probably about 20% at best. The 5.0 gives a decidedly better mpg and amazing torque. Even if only 10% better fuel economy it will be a move towards the mandated 28.5 mpg required of trucks by 2020 (or 2015 in California). The 6.2l has big power and big numbers down low in the rpm range. The svt Raptor R was making over 500 hp with only a computer recal for the hi octane gas available during the running of the Baja 1000. The engineers said the engine was stock, the only change was to optimize the tune.

 

I'm guessing it'll phase out the 4.6 and 5.4 entirely..eventually....however of course now its all speculation.....

 

I'm assuming that the 5.0 will power all Expeditions, Mustang GT's and many qof the F-150's. The 5.0 is as much a Ford signature engine as the 350 was for GM.

The question: The 4.6l 3V in the stang GT makes 305 HP and in the F-150 only 290. When the 5.0 makes it's way onto center stage, what will be the power differences between the car and the truck?

Have u seen one of these 5.0 engines in person yet and have they done any testing yet that u have seen???? Hope this will be my next engine.

 

For 2010 the 4.63v makes 315 in the stang but was 300 before that. I think we can safely assume that the 5.0 will make quite a bit more horsepower in the stang but with probably less torque than the F150 version of the same engine.

These are just my guesses but I can see a 400hp/360 ft lb stang and 340hp/380 ft lb F150. Im just guessing. Im sure the torque curves will be different but Im praying the 5.0 is bullit proof because a lot is riding on this engine. Ford cant afford any screw ups like spark plugs blowing out or anything like that. FWIW, I have always felt the 4.6 was a more reliable piece than the 5.4. I would kill to be a fly on the wall to see what is going on with this engine.

I truely hope the 6.2 will be available to those who really want and need a torque monster. My guess is that the 5.0 will be the biggest seller by a long shot. I think there will be a lot of buyers that are "shaky" about purchasing a EB V6 for the first few years even if it is more powerful and gets better FE. I think durabilty concerns will be the issue.

 

I agree, my concern w/ the EB will be L-T durability. Its an alumium block. For example the new baby 4.4L diesel will have @ 420ft/lb tq and it (like Gms 4.5L diesel) will have compacted graphite iron block to handle tq. Yet the EB will reportidly be @ 400ft lbs tq and be aluminum... Now obviously Ford is designing the EB to handle the power it produces, but given its being used in Flex, Edge, Taurs etc.... it's either overbuilt for the cars or underbuilt for the trucks.

The EB will have so much aftermkt potential. A diff tune, diff turbos, headers will all make real seat of the pants differnece. From what I read the 5.0L might inch up towards the current 5.4ls tq, but I highly doubt it will exceed it. And at what rpm?

What I want to see is all three, no lets include the diesel too, all four engines in a F150 with a 10,000lb trailer, and then race up that hill from hell at Fords proving grounds. That and passing 50-70 with trailer. That will tell me which engine I want.
I suspect the hill climb would be like this:
#1: 6.2L (@ 400 hp/400ftlbs tq)
#2: Diesel (340 hp/420tq)
#3: EB (most unsure of numbers here @ 375hp/400 tq)
distant #4: 5.0L. (@ 360 hp/350 tq)

Turbos pulling up the hill help the EB and diesel distance themselves from 5.0L.

MPG Towing:
#1. Diesel... easy
#2. EB
#3. 5.0L
#4. 6.2L. Big gassers can reeeally pull, but takes fuel.

MPG: 70mph cruise for 3 hours.
#1: EB
#2: Diesel
#3: 5.0L
#4: 6.2L

 

Thanks for the correction. My money stays with the 5.0. I would be very happy to see Ford keep the 4.6L 3V as the base F-150 engine. I too think the 4.6 is more reliable than the 5.4l. I've two of the them and would gladly have another.

I dunno about that. Think about how many people actually keep a truck for more than 5 years. Not as many as there used to be. Peeps keep things till the warranty is getting close, lease is up, then get rid of them.

 

6000lb truck w/ 5.4 is a gas hog, too. 16 MPG combined is terrible.

They're desperately looking/designing for an engine that'll help them meet the upcoming CAFE jump.

We all know My Feelings about the weight of the F150, So I won't go into it. But IMO, they'll have to lighten the truck eventually. Or pay stiff fines to the Gov.

 

You're certainly right about that. Which will force those of us who need lots of towing capacity to move upwards to a heavier, more fuel hungry 3/4 ton. As long as they still make 'em, I'll be happy!

And I don't think they'd be able to get away with stuffing the gas hog 6.2L V8 in regular production F150s. Because a large proportion of buyers would want it, which would mean that Ford's Corporate Average Fuel Economy(CAFE!) would suffer, which would involve millions in fines for not meeting fuel economy goals. Even when the cause would be giving consumers what they want....

 

The F250 5.4 gets virtually the same fuel mileage as the 5.4 F150, and they weigh within 5-600Lb's of each other

 

Right, but the V10 doesn't!

Same engine in a heavier vehicle may do wonders for stability, but really wouldn't be much of an upgrade IMHO. I figure the -250 adds about 1000 lbs over the F150, so it'd need more power to have comparable performance, especially towing.

 

The 250 outweighs the 150 by about 5-600 lbs: Crew 6.5' depending on options.

Not 1000lbs
