Ford does watch this forum like a hawk, which is why I've been so careful to keep the identity of myself and my 'inside man' at Ford a very closely guarded secret, and to keep info leaks conservative and close to their public announcement.

 

Can your guy get copies of the Erin Andrews videos? :happy feet:

Fusion and Mustang will definitely get it.

 

F-150... not 100% sure on that one. As people have mentioned here... F-150 is KIND of a big guy, and no matter how much boost you have, an I4 just might not achieve the efficiencies to make it worth the trouble.

The 5 cylinder from Volvo may just be the ticket for F150...after it got the Ecoboost treatment

A 2.5L EB might overtax the bottom end of the engine----close to, if not over 300hp in heavy load applications might break the engine.

 

Just keep the rpm up. You don't need to red-line the engine. Just move the revs from 1300 rpm to above 2000 rpm. Modern day transmissions have lots of gears to make this posible without over reving the engine. Keep the revs below 3000 rpm and you won't waste fuel.

It'll work just fine in the right application. The truck we use at the dealership to haul body parts to the rural body shops is a 2003 GMC regular cab,long box, 2wd, with a 4.3L V6.

 

That truck will never haul anything close to it's capacity. It just needs to haul the hoods,fenders,bumper fascias, etc. They're not that heavy but they take up space.

 

You don't need 400hp to haul a refrigerator 8 blocks to the customers home.

 

Will it work in a 4x4 Crewcab? No. I don't think it's intended for that.

 

Very good point. I think Ford will try to cut some weight out of the F-150. Add in the weight reduction from using a 4 cylinder. I think it is posible.

and esactly HOW would THAt save gas?

Most cars today rev between 2000 to 3000 rpm 95% when under load. When not under load, then rpm is not an issue and the revs can drop to 1000 rpm. I don't see an issue of fuel efficiency. Unless you need to rev the engine to 6000 to get the power out of it.

simple logic...raise revs at any given speed, consume more gas...........

Not necessarily. If the engine has to do more work (ie generate more horsepower) to maintain a given speed at the lower RPM, it could very well use more fuel. If that wasn't the case, every car would be geared to run just above idle at highway speed.

you had to bring up diesels again didin't you....LOL! ...my point is i just DON"T fathom a 4 eco in BIG, HEAVY vehicles, the stress of inertia and having to rev to produce acceptable results would defeat ecos benefits...MPG's...and raising revs to counter the stress on bottom ends would also defeat the purpose....like I said, at least in a pickup sense, i would rather have a LARGE engine working easy than a small engine working hard.....and i have a feeling a majority of the buying public would agree....6 eco maybe, 4 NO!

I guess that's why the F100 rumors won't go away. OEs are really looking at how people actually use vehicles over what they just say they want, which is always tricky. Dealerships, Home Depot, etc. know exactly what they need so there's definitely a market for a decent sized 4cyl. truck. Plus CAFE rules or $3.50+/gallon gas will may create a market.

me either....although isn't that the engine in the Focus RS?.........

Yes it is. Now, I don't remember what the future is for that plant. Before the announcement of the sale of Volvo, the 5-cyl was looking to be eventually phased out for the Volvo I4 (different animal from the MZR) and 3.2L I6.

Yes. When comparing a 4.0L runing at 1500 rpm or a 2.0L running at 2000 rpm, I don't think you would see much difference in fuel consumption. Mean while a turbo 2.0L can kick out the same power at 3000 rpm as a 4.0L non-turbo. That gives you fuel savings. If you don't need power both engines will run at 1000 rpm. The days of 6000 rpm turbo 4's are over.
