just driven from outside Belfast to Londonderry in 1.3mjt- average mpg 74.3 return average 74.1 , very pleased with that.
 
OK, so being a sad anorak I have just sat down & done an excel spreadsheet using the official FIAT economy figures on my 1.2 doing55.4mpg & a a deisel doing 67.3mpg for the 275 miles I drive every week.

If I have bought a deisel I would save myself......£2.26 a week, or about £103.96 a year.

So over the course of 3 years ownership I'd save £311.88.

I guess for the mileage I cover the extra £1400 for the deisel is no where near worth it as come resale time there is no way the deisel will be worth £1088.12 (cost difference new minus saving in fuel cost over 3 years) more than the petrol model.

Mark the way I look at it is this. Buying a 1.2 never even crossed my mind as there engine is just too weak to go up the hills in my area. I therefore compare it to the 1.4 its the same price and it has more mpg, better torque and less car tax.
Therefore if dont compare it to a 1.2 (y) and you made the correct and only descision.
Diesel for the win untill a torquey turbo is available :slayer:
 
I got my last fill of diesel for 110.9 I think which saved about 7p a litre. I bought a diesel for the torque and economy. As for trying to better my economy figure I think this would be possible on a really long run staying around 60mph. I read recently that you use 10% more fuel at 70mph than at 60mph.

Thinking longer term. My post on breaking even between the two.





Fuel economy. Using the cheapest fuel stations around my area.
petrol £1.03 Diesel £1.10
Price difference between cars £1400
Fuel economy on the combined stat. 1.2 55.4MPG 1.3 67.3MPG

Now 4.55 litres in a gallon. so with a 7P per litre difference in the price of the more economical fuel. We need to save £1400 pounds in fuel for the premium of the diesel to break even.


Excuse my maths here. :eek:

10,000 miles will use 821.7 litres of fuel in the petrol costing £846.35
10,000 miles will use 676.13 litres of fuel in the diesel costing £743.74
so for every 10,000 miles you claw back £102.61

so the £1400 pounds difference is divided up by the 10,000 mile difference to give the amount of 10,000 chunks you would need to complete before you break even. which is 13.64 so this times 10,000 will give you the mileage you need to do to break even. :cool:


136,438 miles then after that diesel is cheaper. :)


Feel free to correct my maths I know I'm rubbish at it. :(
 
Well im convinced :mad:. There is no real finantial reason to buy a diesel based on price differentials of initial cost and running costs. The resale differential is unkown atm but it is unlikely that we get that much money back so all thats left is the difference in the engine character. I like torque, but is that worth £1400? I guess thats a personal thing ! I have a diesel on order so I made my choice (y)

These arguments can go on forever, depending on your choice! The 1.2 won't go up hills at 2000rpm but how on earth do you think the Italians managed in the original 500, it isn't a flat country you know. Down a couple of gears and a bucketful of revs and up she goes. For a someone who likes a revvy engine the 1.3 doesn't come near touching the 1.4's performance.

It comes far more down to driving style preference than a "correct" decision financially.

If we stay at sensible speeds in the 1.3MJ it always hits above 70mpg, but even gunning it everywhere we only drop down to mid 60's.

Not many cars will go 0-60 in under 9s, hit over a 115mph and still return those king of figures! :D

We have done just shy of 10,000 miles testing and hooning about in it and still I am not bored of it. I went from the Midlands to Chichester, then Gosport then Salisbury before back to the midlands today, yesterday I went to Ripon then Wrexham before goingback to the Midlands and its cost me about £60 in BP Ultimate :)
