General TwinAir Thread (including MPG)

Toyota IQ owners, are having even a larger discrepancy in mpg than a TwinAir
and looks to point to the newness of the car. Mid 30's mpg, which frankly for a car so small/light, and SO slow 0-60mph in 15 secs - is very poor.

But anyway, I look forward to TwinAir mpg figures when a few thousand miles are put under the belt 5k+ and when summer hits :)
I'm sure the mpg will go up.

Also maybe the advanced fuel formulations from Shell and BP perform better than the cheapo supermarket fuels.
In the 90's anyway, I always found the supermarket fuels returned less mpg on my same commute -34mpg vs 31mpg. I avoid the stuff now, so don't know if this difference still exists.
 
There is always so much talk regarding mpg on this forum. OK so petrol prices have gone through the roof, but the Fiat 500 is not a cheap car to buy. It's not generally dsiscounted like some other makes. Yet after the initial outlay of purchasing the new car, many owners seem almost paranoid about the need to produce very high mpg figures. It seems that the new twin air engine is pretty good. if I bought one, I'd try not to get too hung up about what initialy, at least, is not great economy. As for "econodriving", I don't think that its necessarily the best way to drive and certainly not the safest.

Just my views, probably not shared by a lot of others.

I agree. If i was that bothered about saving money on petrol i would have just bought a cheaper car and save so much more.
 
The issue is that Fiat lay claim to the most efficient petrol engine in the world with the twin air, which clearly it's actually no where near true.

My 1.2 is more efficient, and that engine is eons old now.

My point exactly. There are people out there, right now, buying 500's with this engine only because they think it'll be more economical and better for the environment than buying a 1.2. In my opinion, those people may well be being mis-sold.

This is a very good point and the total cost of ownership for me has a big impact.

My car is on finance from FIAT, I ordered it in Oct and there was a chance it would have been delivered in December. If that had been the case I would have taken out the finance deal on offer then.

However, because it was delivered in Jan and because it was a TWINAIR I was able to get the finance deal on offer for that model and that period. A quick bit of maths and this saves me £1000 over the three years, presuming I buy the car at the end. This is because FIAT put in £750 and the APR is half the rate quoted in Dec. So I have a car on finance over three years, where the total amount payable by me is less that the curent list price.

I am very happy with that.....

Bingo!

cost per mile (including fuel, depreciation, tax, insurance, servicing) is what matters

And if you buy the car for cash (with a £2000 discount off list price) and keep it for 10+yrs, the numbers look very different - and the fuel cost will be the largest number.
 
most people dont keep the car for 10 years

Which is one reason why there isn't a 'best' engine option that can be universally applied across the board. Each individual's personal circumstances are different, and everyone needs to work out for themselves which choice is right for them.

That's where factual information, based on the real world experiences of all you good folks on this forum, is so helpful - and everyone's story is another useful bit of information we can all use to help us decide what's best for us.

So I'm just posting what I chose to do & why I thought it would work well for me. I can't comment on whether the twinair will or won't achieve its stated mpg - I don't own one - but for those who think it matters, I can confirm that the 1.2, driven carefully, most definitely can - and that information might be useful to someone who's contemplating a purchase.

Umm, efficiency isn't the same as economy. And their actual marketing line is the lowest CO2 emitting petrol engine in the world.
 
I have had another short bash with me and three others in the car,.



:eek::eek::eek:
:devil:

I heard Jezza having a go about it's mpg on top gear last night - not very complimentary.
Trouble is, you stick a hairdryer in a small car and what do you expect? Pound for pound that engine will have to work harder to cover the same journey as something marginally heavier/larger but with a much larger engine on board

I believe the critical point for getting the MPG that Fiat claim is the technique for driving a small capacity, two-cylinder, turbo'd motor- ie, when to upshift for maximum efficiency and finding the balance between low-rpm and turbo spool when accelerating up to speed.

Also, were any of the figures obtained by Journo's and by owners achieved while using the 'Eco' setting?

People often whinge that's it's "impossible" to achieve the official MPG figures, but many drivers in fuel economy/MPG Rally's manage to beat them. So yes, they may not be 'realistic', but they're not impossible.
 
Totally agree that the real improvements will probably be down to developing the correct driving style and I have been experimenting with the eco mode for exactly the reason the D4nny8oy suggests.

However, after a regime of strictly following the change up/down arrows and trying to ignore the urge to change down when the engine seems to really struggle with the gearing I have come to the conclusion that there are more important things to concentrate on.

Although I haven't noticed any improvement in MPG I have noticed a sharp drop in driving satisfaction so from now on fuel consumption will not be my main concern but enjoying the car as a whole.

If only many other owners would focus on enjoying the car and forget about squeezing every last mile out of a gallon of fuel! :worship:

At least now you won't have to leave half an hour early to pootle along at 50mph on the motorway with HGV's up your backside and turn up late for work, just to save £5 a month. :D
