How comes the hatch has better fuel economy....

Been looking at the Hatch's figures, and noticed that although it's heavier than the 2.0l blob and bug (cozve the 2.5l block i'm assuming), that it has better fuel economy as standard?! 27mpg to the blob/bug's 23mpg claimed fuel consumptions.

Can anyone explain this technicality?

To do with the 2.0l block having a harder job? But then what of the weight difference the 2.5 has to move...hmm..

Modern day engineering I suppose.

I can only dream of 23mpg!!

haha same here mate...17 for me

a 2.5 engine is of same size and almost identical weight to 2.0, the hatch has much longer gearing STI models, full variable cam timing(both inlet and exhaust) also more aerodynamic and has intelligent setting on dial on centre console, driving off boost in this setting i was getting 26mpg and at a steady 70-80mph on motorway 30-32mpg but that was on an engine i built so that says it all

Yup 15-17 is about normal, damn my heavy right foot!!

Haha yeah my right knee needs to be stretched out quite often haha. Suppose you don't buy a Subaru to drive it like a Nissan micra lol

usually mine sits around 26.9 mpg most of the time. give it some stick and will drop to 19 mpg
steady motoway cruise about 70-80 i got an amazing 35.9 mpg dunno how but it did it.

That's really good that!! My combined as I say is 17 so god knows what it is off boost and when I boot it. Guessing prob 26 and 13

Think whatever the differences are this thread shows - a piece of paper could say anything!

where not on about a piece of paper here, mines worked out on miles per litres of fuel used
cant vouch for anyone else how there working theres out

Yes but the bit of paper that came with your car that shows the 'MPG' your car should get, isn't the same as what you get actually driving it - like the 19mpg but the 26.9 is close.....closest I've ever known. I doubt most members on here get the fuel economy their users manual states on a day-day basis. Always depends how you drive, load etc

Like my Landy, pointless trying to work it out as you have to fill the tank then see how much it uses, so I have no doubt at all carrying 90 litres of fuel would make a difference

It said it in the manual :-$ haha

..nah I work it out one of two ways, but usually:

Go to petrol station just when the red light comes on, stick like 30quid in for example and reset odo, see how many miles it's on when the red light comes back on.

Say it's £1.19 a litre i'll divide the £30 by 1.19 so that would be in this case 25.21 litres. OR just look at my fuel receipt to see how many litres :-p

Divide the amount of litres by 4.5 (as roughly 4.5l to the gallon) = # gallons.

Then divide the amount of miles by the amount of gallons = MPG

I just use this as a rough indication of my mpg but it usually always works out between 17 and 18 so i find this method accurate enough for me

iam getting 26.8/28.8 on average useing it as daily drive , getting into 30,s on longer runs

easyest way to work it out fill up the nx time u fill up take mileage convert it into km & divde them by lts of fuel added & times this by 2.825 will give u mpg mine works out between 1or 2 mpg less than what car says

but a scooby the wrong car if u want high mpg get a deisel 4 that of a little 1lt run around

Cool I'll try that method. Ahh I'm not bothered about my fuel consumption mate was just intrigued as to how the hatch can get more mpg that saloon when it's heavier..mr kindon answered it very well..bravo fella cheers
