Covered 420 miles on first full tank of fuel, mixed driving (very slow driving), never been over 4.000 revs yet.

To reach optimum fuel consumption figures, prob best not to calculate until our i20's have covered 2,000 miles+. Otherwise, engines still tight, won't produce best fuel consumption figures.
I don't expect to achieve Hyundai's stated fuel consumption figures (54 mixed driving).
I'm not going to worry too much, until car has covered 2,000 miles.

If you've got a spare 10 mins, this website worth looking at, if your interested in general fuel consumption figures & how calculations are made between manufacturers:- http://www.vcacarfueldata.org.uk/informati...ting-scheme.asp

Just worked out my mpg figures for first 3 full tanks of petrol. 42.4mpg (mixed driving). like a snail.
Will enter fuel figures again, once car covered 2000 miles plus.

Early days yet, as my i20 not covered 2000 miles. Hope to eventually achieve around 50mpg mixed driving, if not. Would be disappointed with fuel consumption figures.

my first "tank" (i used 37 litres, the warning light came on) i did 345 miles, which is about 42MPG if im correct, the trip was saying 38 thou, so not very good

my first tank had the trip computer showing 63mpg when i then filled up though Fuelly gave me ~53mpg which was a bit of a difference but i'm hoping that's just something which will settle out to be more reflective.

compared to the Metro it's still a massive jump and especially nice is having a proper sized fuel tank - got 42l in on the first full fill up compared to the 27l i managed at most to get in the Metro even though it was quoted as a 30 or 33l tank (never worked out in the end how true that was).

however the cold weather isn't going to help with people's mpg figures but as they say it takes a few thousand miles on the clock before things start to ease up and help to give you a more reflective figure. then again i'm just happy for something which does upto 500 miles a tank (as seems to be the case) and is costing me a lot less to run per trip. especially nice is having the additional cost of purchasing a diesel offset by the scrappage scheme so that makes things nicer even if mpg is below quoted figures (would only really expect high 50's at most for mine).

it's definitely one of those things to sit out and wait for things to bed in properly like Boroboy is doing, though it's nice to get an idea of how the mpg will change especially with different driving usage, etc which Fuelly and the other sites allow us to track.

Hi there just so you now I have had 540 miles from my 1.4 desiol and I do 15 miles to work on good long roads doing about 60 speed hoping to try and get it up to 600 but think its going to be hard because 540miles was running very low.

On my first and only tank of diesel, i got 4,7 l/100km.
That is 60mpg in British.

Pretty impressive, especially with studded wintertires

Have now covered just over 2500 miles in six weeks of owning my 1.4CRDi i20 - from first fill up have done 2480 miles and used 48.35 gallons of diesel, which averages 51.29 mpg. That has been nearly wholly made up of daily 80 mile commute which covers mix of country lanes, city roads, dual carriageway and motorway driving so should be fairly good as a general average - would hope to do more on a longer journey.

Have owned a 1.4 petrol i20 for 3 months
now and am very disappointed with fuel
consumption.

The best fuel consumption which I have managed is 44.5 mpg and that was in a
journey of 90 miles at a steady 50mph!!

I have measured this by resetting trip computer
at fill up, recording miles travelled (trip) and
gallons used at next fill.

Around town I am getting approx 38 mpg.

Trip computer is way out and tends to read less
than actual.

I have owned many other makes of car and the
trip computers on these are much more accurate.

Anyone else suffering from poor fuel consumption in
1.4 petrol.

I have a 1.4 comfort as well. Its difficult for me to work out consumption because I mostly do mixed driving but I suppose on average I get about 40-42 mpg, not that close to what Hyundai claim, and I've covered 2600 miles now.

I'm a bit disappointed but perhaps its my heavy right foot!

I think the mpg readout is very optomistic but the miles to empty seems quite accurate.

How can you be disappointed when you suppose you get 40-42 mpg? How do you know you don't get more or less for that matter?

It’s not too hard to brim tank, run car, brim tank and note fuel used plus miles covered between fills and you have quite an accurate value for that test period. (IMG:style_emoticons/default/whistling.gif)

When we had our 107 the forum users often used to quantify their exaggerated mpg by saying £10 took me xyz miles. The snag being £10 could buy different volumes of fuel so the values were way off.

Why am I disappointed by only getting 40-42 mpg? Not what the book says is it! Still its not too bad compared to my old car.

And yes I do brim the tank then work out the comsumption every time. One thing it seems we all keep forgetting, or at least not mentioning, is that when it, eventually, gets warmer and we start using the air con thats going to knock 10% off for a start!

4.245km on the clock, 6,6l/100km
In Britain that's +/- 397 miles and 42.8 MPG

Not bad, never drove less than 600km with a fuel tank. (i20 1.2)
Overal fuel efficiency is 7,06l because I drove often short distances in the city for the first 2000km.

Ah, I took your comment to be a 'gestimate' and I know what you mean about the stated mpg being way out compared to that achieved in practice. (IMG:style_emoticons/default/sad.gif)

To be honnest, I'm not sure it's going to make that much of a difference. The 'killer' seems to be (at least for me) the cold starts were on a 10 miles journey the mpg invariably drops until the engine has warmed up.
It tends to be worst on my way to work were I'm warming up the engine on local city streets . On the return however, it's dual carriageway for the first 3~4 miles so, I am covering more distance in a shorter time while the engine warms up.

Air con uses a fair bit of engine power, they reckon it increases fuel consumption by about 10%. Thats not me making it up, just do a little googling. It will bring mine down to under 40mpg (IMG:style_emoticons/default/ohmy.gif)

I agree the very cold weather is a killer too, luckily I dont often do short runs when its frosty.

One poster is/has getting rid of his i20, partly because of poor fuel economy. Ok its not the best in the world on fuel but its not that bad, ,aybe he should get a moped instead!

Unfortunately have only managed to achieve 43mpg (mixed), driving slowly & never using aircon over my last 1000 miles of owning my petrol engined 1.2, i20. No where near Hyundai's 54mixed mpg driving figures. I certainly don't trust Hyundai's over optimistic fuel consumption figures. Over rated, in my opinion. Very disappointing (IMG:style_emoticons/default/mad.gif)

Not that bad? 20% less than official figures is bad in my opinion. Surely that is the point of buying a fuel
efficient car? Hyundai's claim not mine. Check out the i10 posts on fuel efficiency too.

Where's my moped (IMG:style_emoticons/default/laughing.gif)

You're right of course, its nowhere near what Hyundai claim but we're not the pro drivers that they use! I still think a lot of people are going to be even more disappointed come the summer though.

I have only had my 1.4 petrol comfort for 3 weeks, I have filled her up twice, done just over 600 miles (Nearly all stop/start round town stuff) A/C is on all the time (stops condensation in the damp months !) and the return I'm getting is a massive 30 MPG. This is whats shown on the gauge in the car and what fuelly works out but I havn't checked it myself manually

You will never get down to the official figures under normal driving.
You´ll need the optimal conditions, no ac, no hills, no red lights and drive like Grandma Duck.
You can compare with my previous car.
A 1,3 l Suzuki Swift with 92bhp
I got an average of 42 mpg uk.
The official figures was 46 mpg uk.
