Enlighten me, how long do you expect a turbocharged V6 lasting in a 5500lb work truck?
I assumed we were talking about trucks, because I don't really care about little cars. This is the F-150 section the last time I checkd.
Well the 4.0 toyota makes simliar hp and torque when compared to 4.6 ford v8. Add a few PSI of boost and I think we would have a good V6 truck engine. Seems like it should last as long as anything else. I don't have the test results to prove this. Do you?

I supposed I should have added SMALL displacement into my question, My bad. I take it that is Fords main idea with the ecoboost. I believe 4.0l is a little larger than they had in mind.
I am surprised that Ford or others for that matter havn't really put direct injection on gassers. The outboard motor industry has been using it for years, that was on 2-strokes though.
Well I tend to think it will be around 3.5 for 4 liters. I would consider that small displacement. Especially if they manage to compete with the 6.0, 5.7 etc. It seems that the big thing is cars and crossover SUV is 3.5 liter V6. I would be very very surprised to see a small displacement engine running high boost in a full size truck.
I believe direct injection is coming soon to ford. You are starting to see it more and more.
I just think we all need to sit back and watch what ford can come up with. I wouldn't worry about a serious flop though. The marketplace is too competetive right now and ford knows that.

Audi has a motor making really good power with GDI..

Remember that boost IS displacement, as far as the volumetric combustion process is concerned. i.e. you're burning the equivlent air/fuel mass as a larger combustion volume.
A 3.5L at 14psi is roughly a 7.0L. In real life, it'll depend on a couple other factors...
80-90% of F150 owners don't need 350 HP. Most are used as daily commuters. They could get away with a 250HP V6. And prolly still get 25 MPG
If Ford offered the option of a 350 HP V8 getting 17 MPG, and a 250 HP V6 getting 25 MPG. What do you think would be the top seller?
Unfortunately, the numbers won't be nearly as nice. At a fixed mass and drag coefficient, you still need a certain amount of power to put this thing into motion and sustain it at highway speeds.
With the V6, you're simply using a greater portion of its max available power. You get a slightly higher mileage due to the slightly higher engine efficiency (less reciprocating mass, less heat loss surfaces).
To get a significant gain like 25 mpg, the only choice would be to use a more efficient combustion process - diesels.
yeah, I don't think the V6 Ecoboost is going to have great MPG gains, especially in our heavy trucks. Here's an excerpt from an article about the new motor:
Ford's 3.5-liter EcoBoost V-6, for example, can deliver upwards of 340-plus lb.-ft. of torque across a wide engine range – 2,000 to 5,000 rpm versus 270 to 310 lb.-ft of torque for a conventional naturally aspirated 4.6-liter V-8 over the same speed range. At the same time, this V-6 gives customers an approximate 2 mpg improvement and emits up to 15 percent fewer CO2 emissions to the environment.
A 2mpg increase is not that much. I think they are comparing it to an Explorer with the 4.6-V8.
A 3.5L at 14psi is roughly a 7.0L. In real life, it'll depend on a couple other factors...
Yah that may be BUT, that is only when your spooled up and are at 14 psi when you are flooring it you would get that much boost, other wise you would be getting little if any boost. So on the high way where all of you big mpg gains are at you would be geting the 3.5L mpg not the 7L the 25mpg+ highway is a real posibility.
Well I still don't think 25+mpg is realistic. The honda ridgeline is 3.5 liters, has a lower areodynamic profile, and is lighter and does not get that on the highway.
