There is a new i20 version out now / just about now.

yes that's true this is the one I looked at the'new' i20 I really didn't think about real mpg as to car makers claimed mpg it appears so far apart glad I posted this question

MGP can only be an average, my 4 mile trip to work in a morning averages around 40-42 mpg, the same trip in reverse at 16.30pm I am lucky to get 30mpg so a real average for the trip of 36mpg (Passat 2.0TDI 140) even missing a couple of sets of lights can make quite a difference.
On a motorway it can average 60 mpg so its all down to how, where and when you drive.

The Juke is a better car. Would you be happy driving a shoebox on wheels?

Whatcar suggest the 1.2 petrol is the pick of the range

to answer yes I dont mind driving a shoebox on wheels if I saved money in these challenging times love the analogy you make very funny regards

It all depends on what kind of driving you do, where you do it and how you do it. 13k PA ~ 250/wk. That suggests you have a pretty average commute of about 10 miles each way or just under with the odd long trip thrown in.

A small diesel is unlikely to get warm on a such short trips, increasing fuel consumption. A small diesel is also likely to get DPF (Particulate Filter) problems doing only short, light throttle max economy driving trips. This can be *very* expensive to resolve.

Based on these assumptions I would say your Hyundai is likely to hit ~53mpg on average or about 70% of it's govt figure. Against your 44mpg juke... that difference over a year would be £320. So your total cost to change would be recouped over 2.6 years, but your depreciation loss is already circa £4000 based on current list prices. So you now need to recoupe ~£4835 at £320/yr = 15.1 years before you've "saved" money. (Note this is a gross over simplification as the i20 would have some value and the Juke is depreciating too)

Irony:

New i20 @ £13k, 13k Miles PA at 53mpg worth ~£5k in 3 years = Fuel/depreciation cost of £12685

Old 4.2l V8 Jaguar @ £2k, 13k Miles PA at 20mpg worth ~£500 in 3 years = £13550

Fuel consumption seems the right thing to look at because everyone sees the weekly cost of filling up. Changing a car that does over 40mpg to "save money" is almost certainly a false economy.

thanks for a great reply and time you took,, certainly has given me much to think about however I dont think I would have DPF problems as I do a 27 mile trip daily mixed driving mainly motorways and A roads ( 60mph) but thanks again regards

Great post Chris!

At 27 miles a day trip you should have no DPF problems at all. It's only the "sub 10 mile" kind of work that tends to lead to issues. Good luck with your deliberations.
