Claimed Fuel Consumption on GTI

[prcurrie]

Does anyone ever get the claimed 6.1L / 100km consumption on the GTI? I'm averaging in the 8's!

If it's anything like this lady in the US - I think she's on to something!!!!

It's quite different. When you buy a Hybrid, fuel consumption matters. When you buy a performance vehicle, nobody actually really cares if it averages 2 litres more.

lol, I wouldn't worry about it. That's still pretty good consumption. When I used to drive my Polo TDI DSG - I would only get around 9L/100km in city and about 5.5-6L/100km on highway.

Claimed fuel consumption figures (ADR81) should only be used to compare similar cars.

If you look at the Polo GTI the Urban Figure is 7.7L/100km.

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)

I got a real 6.1L on my Golf GTI after a highway run to the Gold Coast on a 31 degree day and the A/C running - which is bang on the extra urban cycle in the brochue.

How much was due to the APR remap I don't know but they say it makes a difference......

While I don't have my GTI yet, I've test driven three different ones and their consumption has always been in the low to mid 7's (7.1-7.7). I thought that was pretty good considering they're usually driven fairly rough being demos and all.

When buying a car it's best to just go by the urban figure more than anything.

Correct!
The published manufacturer/government fuel consumption figures is a tool that allows one to compare vehicles on a level playing field.

They are not designed to predict (seriously, how is it supposed to do that?) what one particular driver will achieve for their particular journey.

My Aurion ZR6 is rated for 9.9L/100km i'm lucky if i get 16L/100km... I have once got 6.8L/100km driving down the freeway at 100km/h with no AC, fan or radio on at night time - but everyone above is right its going to vary wildly from driver to road to outside conditions.

Used to have an Aurion before the GTI and I always got around the 10 mark. You must have a heavy foot!!!!

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

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

[Karly101]

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.
