1.0L Ecoboost?
 

I see Ford has started offering this engine in the US Focus finally. Surprised me honestly since its a good 40hp drop from the base 2.0L engine.

Pretty much same mileage as the Fiesta 1.0, but you get an extra gear in the Focus. Rated 42 hwy, 43 hwy in the Fiesta.

Anyone have real world results?

Also interested in this. :)

What are the US fuel figures, in Europe we get some stupidly optimistic figures based on an imaginary drive in a closed cell road road in ideal conditions.

Imperial figures
Engine: 1.0T EcoBoost 100ps
Official MPG: 58.9–60.1 mpg
Real MPG Avg.: 40.6 mpg
Real MPG %: 69%

Not interested in DI problems, prefer the 2.0 FFV, KISS

123hp/148lbft
30 city/42 highway for the Focus 6 speed manual (Same as my Mk6 Golf TDI)

I believe 43 highway in the Fiesta 5 speed manual

Isn't the 2.0 FFV also fitted with DI? Even here in Brazil the 2.0 FFV has DI.

I have a sort of Ecoboost, Fiat's 0.875l Twinair 2cyl Turbo.

There's a two sided problem with all these small capacity turbos, boost=fun, but boost also means fuel enrichment (which comes on at very low boost- these cars can't really be driven off boost). Most people will struggle to get near the official NEDC figures, US EPA figures should be easier.

You can look at my fuel graph to see how much my economy improved as the engine wore in (still not fully run in IMO), this is why all the press cars were criticized for such poor economy.

I've managed an 80mpg run of about 14miles, starting and ending at the same point. At around 50mph on 'level' ground I can cruise at 80~100 MPG.

However, UFI is my weekend fun car, so I mix hypermiling with thrashing. My 48MPG 90 day is pretty good considering. We did a run with the Prius and UFI at the same time (switching drivers at half way), UFI beat the Prius by 7 MPG.

Given that UFI's the size of a Geo Metro (but a fair bit taller), and we've seen those hit 100mpg, while UFI's current tank sits at 58mpg -and is pretty close to the limit for this car you can decide if it's good or bad. With the base 4cyl, I expect I'd be knocking on 100mpg, but only with extensive EOC.

So I guess if you like EOC, stick to NA engines, if you don't like to have a bit of fun occasionally and can restrain yourself, these baby boosted models might be for you.

Can't believe how little input I got here

I like the torque curve of the engine; it peaks low and is pretty flat.

Maybe you could post it on facebook?

Have you found any in the Ecomodder garage? Silence is likely an indication of ignorance. Rather than get single anecdotes on a forum, it's more useful to see a compilation of data such as...

My MPG Estimates

Out of only 10 entries, it looks to be averaging 36 MPG.

Ever since gas prices dropped, it's been pretty quiet around here. Even before that, I don't think any regular posters had a 1.0L Ecoboost car. I thought about getting one, a white Fiesta sedan, but went with a Prius instead.

Dont' think anyone has the Focus 1.0 here.

I've driven the Fiesta 1.0 EcoBoost with DCT. Didn't find it any more economical than a decent 1.6, but it was still pretty "green" when I drove it. Perhaps with more miles on the car, it would have been better.

Engine is good. Hate the transmission. A bit lumpy around town. Combined with a throttle that sticks open too long after you let off, it's a bit meh compared to a good traditional automatic like the Mazda2's.

I have had the ecoboost fiesta since October 2014. I have tracked all my fuel purchases since I joined ecomodder in November 2015.

My real-world numbers have been excellent. I typically average about 45-46 mpg during my commute in the spring through fall. When I have to take trips where the drive is all freeway, it easily hits 50 for the trip. Being in Ohio, the cold takes its toll in the winter. Once the temperature drops below 40 F, it is difficult to keep the mpg's up.

My last few tanks have only averaged about 41. We have had a lot of days near 0 F and lots of wind. I have been very happy with the car because of how easy it is to get the good mpg. I have had one tank where the average was below 40 (39.9), which was the first tank I had the car.

I looked over your fuel log, what do you mean by "changed acceleration rates. Seems what works best in the summer is not as good as the winter."?

I started to accelerate more quickly. With the really cold weather, it takes a lot longer to warm up and get into the more efficient zone for the car. Accelerating a little harder helped speed up this process.

I'm considering a Focus 1.0L. Not because the 1.0L is an impressive engine or because it gets good mileage, but because the 5 speed transmission used behind the 2.0L NA engine is awful to drive.

It should work out well. Provided you know how to drive a GTDI engine for fuel mileage.

I haven't been in the Focus yet, but I tested the Fiesta 1.0L a while back. It's an amazing little beast.

I'd be happy to have a Fiesta as a DD, but I'm torn between the tiny three and the ST. So much bang for the buck with the ST. Wicked fun when you're on it and does okay MPG wise if you have the discipline to stay out of the boost.

It's kinda surprising to me that a manual transmission is available for the Focus with the 2.0L there in the States. Here in Brazil it's only available with the 1.6L.

Anyway, since nowadays the 1.0L Ecoboost is the engine of choice in about 25% of the brand-new Ford cars in Europe, there might be a good reason for its availability to be extended to the U.S.-spec Focus too. It has been rumored that it's also coming to the Argentinian Focus, with the engines to be supplied from the Camaçari engine plant.

I'll be looking at a '14 EcoBoost Fiesta later today or later this week.
