Claimed Fuel Consumption on GTI

[sorcam]

Around the city I'm getting low 8's but on the highway I got down to low 6's

[THE_EGG]

But yours was the dud, wasn't it? It SHOULD have been doing much better than that (my older 1.9 TDi Polo does FAR better)

This is true, although VW told me that it still needed to be driven in for a little while to get good consumption figures. But then again they said the gearbox was fine....

Ditto - even got a high 5 on a run down the south coast once

I get 7.5 if I take it easy.. usually not the case so its a bit higher.. still I find it pretty good in comparison to my old dubs..

The figures used for city, highway, and combined are achieved while the vehicle is on a rolling road following a pre-deretmined sequence of speed, acceleration and braking, much like the way vehicle emissions are determined.

This is done so that you can get a true comparison between vehicles.

Now if you ever get the chance to witness a vehicle going through one of these cycles, take up the offer. It will open your eyes to what the particular drive cycle puts a car through. You would hardly think that a vehicle could be driven this way. When I was involved in vehicle emission testing, there were many instances where the trace has to be stopped so that the vehicle could catch up. I am not talking about a tiny engined car. The tests were being done on a 3.3 litre Holden Kingswood.

So the only thing you can ever use these figures for is comparison.

Hybrids cause other issues. You need to measure the energy in the battery banks at the start of the test and then at the end of the test. This then has to be converted to an equivalent volume of petrol and then added to the amount of petrol used. To not do this distorts the results as a hybrid can start the test with full batteries but end it with close to flat batteries. Of course it would give you better results.

Just about to take my GTI in for it's first service. On the highway, I've managed as low as 5.3 and about 5.6 or so seems the norm. Around town it's obviously a lot more variable, but my average when filling the tank (35-40L used) is approx 7.5-7.8. I only use BP Ultimate, if that helps.

prcurrie, I average around town BELLOW the claimed urban figure, I get 7.1l/100kms.

On a trip up to yarrawonga, I averaged 5.6l/100kms untill I hit Winton raceway area, that when I opened up the taps a few times. Even then, 6.0L/100kms for the whole trip.

Coming home was slightly better, more downhill.

[Tigga1]

Road Trip lite shows my average over 10.5k is 7.03L/100km, using BP ultimate.
I tried taking the average consumption of the MFD for a while and noticed consumption went up...probably also the fun factor...(-;
having said that, driving for economy can be fun too

[GraveDilute]

Well I trundle up and down the Ring Rd for about 35kms one way, twice a day.
I fnd the sweet spot for economy is to travel at 90kms/hr. If I get a non stop run to work then I get 5.5-5.9l/100kms.
My total average urban and highway sits on 6.9l.
Can't complain as my Mazda CX7 struggles to get below 13l

[RoknRob]

I've been getting between 7.44 and 7.84. I try to drive as economically as possible, but, geez! It's just too tempting to the open up the throttle!
