Looking into possibly getting a Fiesta with the new Ecoboost engine, was just wondering if the quoted figures from Ford for MPG is anywhere near accurate. Have seen between 55-70 advertised depending on style of driving etc.

Seems most are around the mid 30's - 40's in the Fiesta's so far, but then again they're not run in at all. Going to be a while unfortunately before true figures come through, so it's either risk it or wait. Either way, it's a nicer engine than the 1.6 Ti-Vct engine it's replaced, and should in theory be lower in fuel consumption once the car hit's that sweet spot in being run in. Titanium's are probably going to get the best MPG due to their cruise control, if you use motorways.

I have had the 1.0 Ecoboost 125 Titanium X for just under two weeks - the mileage is about 600, my average MPG is just under 40.  About half of my miles are motorway (dual carriageway) using cruise control and half are more urban - cross City.  I have tried to drive VERY economically - there is an indicator of your eco status in the menu under Ford Eco and when I was pretty much top for the three areas measured (gear shifting/anticipation/speed) I was still only able to get about 42mpg.  Driving more normally I am achieving about 39.
 
B1g_dav3 mentioned that figures may be lower for cars not yet run in, the book does say to not try and determine fuel economy until you are past 1000 miles, but typically 2000+, so I’m hoping the figures will improve.
 
I moved to this from a Diesel where I was achieving on average just under 50 (the book combined was listed as 55) - I was hoping for about 55 (book states 65 for combined) from the Fiesta but is it really possible that the economy will improve by about 30% after it has been run in?
 
The only other thing to mention is that I upgraded from the standard 16" wheels to the 17" ones - that could affect my economy but I would have only expected to lose 2-3mpg for that?

Hi, any manufacturers quoted mpg aren't accurate to 'real world' motoring and Ford state that on the back page of the brochure. Most cars get to about 80% of the quoted figures http://www.honestjohn.co.uk/realmpg/ Cruise control will never ever give the best mpg either on our roads unless they are totally flat and without any air resistance....

I would be very happy if it ever achieves 80% of the combined figure, that would give me about 52mpg, to be honest even if it only manages 70% (around 47mpg) that would be better than where it seems to be at the moment. 

 

The focus with the same engine claims 56.5mpg (combined) from the Ford figures and Honest John claims an MPG of 40.8 - 72%, so I may achieve near 50 in the Fiesta using those figures. 

 

Time will tell but hoping for an extra 10 :-)

The trip has been reading 40+ mainly back roads town driving, no motorway.

[gregberry]

Had it on 50mpg when I reset my trips after filling up the other day and I was motorway driving. But… I only drive around town usually and keep it in gear for ages so I normally am getting 39mpg which i think is pretty decent considering.

Morning

 

Im at 40.2 MPG, 500 miles in, i do 1 junction of motorway and abit of town per day

 

I used to have a 1.4 05 fiesta zetec, ive got a ecoboost 1.0L zetec now. In the old car i got £25 pound to last me 4/5/6 days on average, currently hitting 8 days with the new one

 

Like others have said i dont think it will get the full effect till 1K possibly 2K

 

How do you reset MPG calculator? going to do it after 1K miles to see improvement or not

 

Josh!

When the average mpg is displayed press and hold the selector on the stalk.

My mpg is increasing still day after day driving now showing 48's. been increasing ever since i filled up with v-power. Fords figures are quoted as been on BP Ultimate. No idea what the car had in it when i got it but so far my current half tank has gone alot further then the half tbe car was supllied with. Anyone else tried using super fuels in the ecoboost? As ford reconmend or just reg?

[Sliveredge]

I stuck vpower in it the other day and it appears to be reading higher mpg by 2 or 3 in the lower 40s now was about 38 before could be engine wearing in but my routes and driving have not differed at all.
