Honest "real-world" mpg predictions for the GTI & GTI PP

[Hawaii-Five-O]

Just wanted to get your views of honest "real-world" mpg predictions for the Mk7 GTI.

The official combined mpg figures are as follows:

Manual GTI 47.1mpg
Manual GTI Performance Pack 47.1 mpg

DSG GTI 44.1mpg
DSG GTI Performance Pack 44.1 mpg

What do you honestly think the combined mpg of the the GTI will be with a variety of driving styles (i.e. Motorway, A Roads, B Roads and a bit of a hooligan blast every now and again)?

For example my current cars claimed mpg is 44.8. But after 4 yrs of driving the "actual" figure is 37 mpg. So that's nearly 8 mpg down on what they say it should do. Gets you thinking.

I'm expecting around 25mpg, most of my driving is short journeys and I plan to use the whole rev range whenever possible. 

I expect 35-40mpg on a careful longer run.

You can use this site to find your figures if you don't know them:

Scroll down and do "MPG search for used cars"

Here are my official figures:
EMISSIONS & FUEL ECONOMY
Urban MPG: 35.7 mpg
Extra Urban MPG: 60.1 mpg
Combined MPG: 47.9 mpg

What I actually get in the real world:
Combined MPG: 38.0 mpg

So I'm about 10mpg down on the supposed combined MPG.  To be honest the official figures are a pile of sh!te for my car.  I once spend about an hour trying to optimise my MPG by varying my speed until I found the sweet spot.  I managed to squeeze 50mpg out of it.  That is still 10mpg down on the officially achievable value!

I've also found it makes relatively little difference whether I drive like a saint or throw it around like a madman.  Even pushing the car to the limit gets me 38mpg.  Being sensible... hard to say but 40mpg is probably tops.  The 50 I got was late at night on a straight open road which went on for about 60miles and I could just sit there and focus everything on slight throttle variations while watching that MPG counter.  Could never repeat this if I had to use the brakes for roundabouts or lights or other drivers...


Now, being a  I would love to do, and will be doing, a study into the mpg I can get using a specific fuel, likely Tesco 99 when my GTI arrives.  If anyone wants to join in and stick to a specific fuel and track their figures that would be awesome!  When the darn thing arrives I'll post up what my plans are.

In general I find I get 10mpg less than the manufacturers stated amount.

If the reports of the bad mpg with the 150 TDI engines are anything to go by, it will be much worse than expected. I know when I test drove one for a very short period at actually quite slow speeds it rose to 30, a small blat in 3rd ramped it back down to low 20s.

Try coasting. Seriously. It makes quite a big difference with modern engines. Obviously no use on most motorways but works quite well on undulating A and B roads. I can get a 5-6 mpg difference when I can be arsed to use this method.

I expect an average of somewhere in the mid - high 30's based on my driving and current figures.

Couldn't give a hoot personally.

My current Scirocco is quoted at 37 combined and I obtain 32. With the GTI being quotes at 47 I'd like to see 40 and I think it will be doable..

This will be a sticky in the TDI section when it starts up.
