Ford Ecoboost 3-cyl Summer 2013

Ah. Got it. Thanks. The little 1L generates a little more HP than my 1998 Civic's 1.6, so I'm really curious to test drive the little thing. Would be a bummer if they postponed it.

To get that most of them are decreasing the turbine efficiency as they aren't using VGTs, and building up quite a bit of backpressure in the exhaust (even with electronically controlled wastegates I imagine). A 1 liter engine is probably going to be at high enough load levels on the highway to generate some non-trivial amount of exhaust pressure like this.

To ford's credit, the 1.0 is a closed deck iron block motor and at low load (highway cruising) they can use an open TB, open waste gate strategy that minimizes back pressure most of the time. Essentially functioning like an NA motor. The engine management strategy on most of Ford's ecoboost engine is completely different from the classic cable throttle and boost controlled wastegate we all know and love. That said, I still prefer a normal size 4 cyl non turbo motor with DI. The 2.0 mill in the focus is a descent sounding mill at high revs.

Closed deck iron block? I'm not super well educated on this subject, what does the iron block do for it?

Certainly it's not the classic spring wastegate setup and throttle cable, all manufacturers have ditched at least the throttle cable already, but my question is sorta, how much can the wastegate really relieve pressure? A larger valve makes it harder to accurately manage exhaust pressure under load, so I don't imagine it's much larger than the typical wastegate, it's just that it can be opened before reaching a pressure threshold.

IMO positive displacement SC Miller cycle engines are the answer, but that's just me :P

I think the 1L engine would be perfect for a car similar to what the Volt was originally supposed to be...an electric car with a gas generator to recharge the batteries beyond what regenarative braking can't keep up with.

Ford could do one of those across the whole vehicle lineup.

Honda and Ford should get together.

The 1.0L EcoBoost can do 123 hp and 125 ft-lbs torque.

Add to that the 15 hp and 46 ft-lbs of torque from an IMA motor in a Civic Hybrid, and you've got roughly 140 hp and 170 ft-lbs of torque.

IMA gives torque down low. Assist weakens as RPM climbs; but by then, the turbo is spooled up and boosting nicely.

Gear it low so that it's doing 2,000 RPM at 60. Just barely fast enough to have the turbo going. Those of us who like 55 would be completely out of the turbo on the highway, and our economy would skyrocket.

Even more awesome would be if they could map a zone from 45-55 where the turbo isn't spooled up, and it drops into lean burn.

Sound's complicated, I'd rather have a 8 speeds behind the 1.0 so always a good gear for the task, with a dual disk automated manual so it can change gears faster than me.

Some user input on how I'd like it to shift at light to moderate throttle would be great, floor it, let it rev, make boost, make good noise, and put a smile on my face.

I have to wonder if as the price of fuel goes up, if you will want even higher mileage. Thoughts?

Well, if this 1.0L 3 cyl comes in a 5 or 6 speed manual, I'm sure many many of us on this site would get far more than the EPA ratings almost immediately. If I could double it like I do my Civic, then 90-100 MPG would result.

[thomason2wheels]

90 to 100 mpg in a 4 wheel conveyance that can carry more than one person would bepretty sweet. Makes my little ninja look pretty silly at its paltry 67 mpg.

Another story about the car, this one a driving review:
1.0L EcoBoost 3-Cyl. Shockingly Quiet, Capable | Road Ahead

They claim to have gotten 39mpg (US) while driving it all day like this: "Cruising in the fast lane in sixth gear at 75 mph (120 km/h), the 1.0L Focus happily accepts a downshift all the way to third gear. And just for yucks, run at wide-open throttle until the red line forces a higher gear. The engine responds enthusiastically, without hesitation and as if it’s barely working."
