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.

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.

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?
As I posted before. It'd be easy to get a Forced induction V6 to put out 300 HP, and still be dependable out to 150K+ miles.

A 3.5L at 14psi is roughly a 7.0L. In real life, it'll depend on a couple other factors...

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.
