Autospeed:"But if there's one major downfall of the engine it's in its fuel consumption. Despite people telling us how - for a big V8 - the fuel economy of the Gen III is good, we just don't see it that way. On test the Ute achieved an average of 18 litres/100 km - which can only be described as dismal. Unlike many high performance cars, where you can get reasonable fuel economy if you give it an occasional squirt and then drive gently the rest of the time, the 5.7-litre requires incredibly gentle and consistent driving all of the time if it is to get acceptable fuel economy. As in, pull out of the petrol station, get on to the highway, select sixth gear, then not move the throttle more than a few millimetres. That way, yes the economy can be around 10 litres/100 km. But in normal performance car driving, it's simply atrocious. But unlike the Monaro we drove - which had a similar thirst - at least the Ute had excellent performance."
Just read the New Car Test on the Vy SS Ute on Autospeed. This above paragraph caught my attention about fuel consumption being 'average 18 litres/100km' as my next door neighbour who bought a black Vy SS Ute just recently, was telling me the other day that he was getting like 17 litres on average driving. That's like 4-5 litres more than Holdens claimed 13 litres/100km? I'm not flaming no1 here, I'd just like to know(as much as my cousin does who is looking at buying a VT II SS ) your thoughts on this, especially of those here on the forum who own 5.7lt Commodores.
Well the Falcons economy isn't to good either but I don't think they lie about it like Holden do.
From memory the new Xr8 claimed around 16l/100km but the wheels test found it to be more like 20l/100km (with some obvious hard driving)
I don't really think fuel usage play that much a part of the total running cost of a car.
I was reading an artical in the Raa propaganda book saying that fuel cost was about 15% of the running cost of a car.

What sort of figures did Grungy (R.I.P) get Cam?

Clicky clicky here for previous ride! I still miss her!
they both started the same high consumption and than into that same range after a few thousand kms
I dont know how they test these figures. I think the fords would be the same (high initial consumption when you get the car because you change driving style work out the car a little more etc)
Even in my 6.2 I get 16l and 10 country if im not on the pedal all the gime
Who #$%^^^ cares what economy it gets, my theories on this are: you only live once, enjoy it !,,, why save petrol for the Arabs???,,,,,,,,,when im at the lights surrounded by 4 cylinder vehicles, i say to them "thank you for saving petrol so i can burn it in my V8s"

Actually, Ford claim that the XR8 can get 12.5L/100km, and a recent test drive somewhere claimed that this was more like 16L/100km during their test (actually, 15.6L/100km now that I've found the link: http://carpoint.ninemsn.com.au/revie...ry.asp?ID=4680).
This 12.5L/100 that they plaster on the XR8 windscreen is bizarre, because the sticker plastered on an Auto V8 Fairmont windscreen is 14.0L/100km
