Thought it was a result worth posting, I just did an economy run from Dunedin to Invers, well not really an economy run but treated the accelerator like an egg shell. Overall average speed was about 100 km/h. It was in a 98 Nissan Primera, SR20VE with aftermarket tune and manual conversion. Not bad for a 200hp, 1370kg Wagon.

That really is quite remarkable. I guess it's running fairly lean. It would be mildly interesting to stop and open the bonnet mid journey (on a dark night) to see how much the headers were glowing.

Not bad at all but in saying that when I grandad my 5.4L 400hp BA XR8 at 2100kg on the same trip I can get 9.1L to 100k's cruising at 110kmph. I think you and I could kill the good results if we put the foot down and pass a dozen or so cars on the way :)

Hmmm.what was you're ACTUAL average speed! Pretty rare in this country to get over 85 on any section of highway that long.

according to eftpos dockets, 2:12 to do 208.2km, 94 average including towns.

How many rpm were you doing at 100km/h! And what size tyres did you have on the car! Those figures are very impressive for a 2.0 litre wagon.

Very hard to average close on 100kph. If I really lean on it from Queenstown to Christchurch I can just about do it but I'm often showing 130 on the straighter bits to offset the twistys, other cars and towns.
Was that a 'brim to brim' fuel check or OBC reading!

With an average speed that high it sounds fine. If I can average over 90 my Falcon will do 7.6 (no egg shells in sight), so 6.2 and taking it easy doesn't sound unreasonable.

That good economy alrite.The roads are good down there,and very little traffic,your not continually having launch pass idiots,so you can maintain your average !

From day 1 to date, Dec 2002 Cooper S (1600cc supercharged) has run at exactly 7.0L/100km.That is all weathers, all traffic conditions (far too much time stuck at traffic lights.).If I could cut out all the frustrating stop start stuff, and getting stuck behind those who womble up the local hills at 40kph, the figure would be really impressive!Yes a generally light foot, but a six speed manual gearbox, used sensibly is a great help too. Freelander 2 diesel, overall to date (3 years 9.0L/100km) would be better if it too was a six speed manual, as the 6 speed auto doesn't shift into top until you are doing about 90kph anyway!
The trick with economy is not just your cruising speed, it is the amount of time you are in anything less than top gear. That is why 105kph in 6th is far more economical than pootling along at 85kph in 4th.Accelerating from rest is the really big killer, (especially uphill) so if you can keep moving, it makes a huge difference. A 2 litre car is often more economical than a 1500cc car too.

more importantly, its the VE engine
not the DE
the wagons are 90 kg heavier than the sedan, & im gettingin the 14 km/L range from my sedan DE primera
hes just touching 16 km/L

Something,s wrong with your figures, it,s more than 208k Dunedin to Invercargill, for a start
he did not say centre to center and has no reason to tell porkies!maybe he started just north of dunners!

Get a six speed conversion and taller diff and you will achieve even better.Andreas Miko on SR20-FORUM suggested this years ago your fuel economy will be even better than what your getting now.Also you can chip the ecu and set it up for a leaner burn in the 16:1 afr range under cruise conditions. I had my vz-r n1 running like this at one stage and even with its short ratio box and final gear it got decent enough economy.
Has nobody on this board heard of the old honda crx hf!
They basically took a run of the mill crx with the 1.5 and changed the gearbox and a few other little bits and it supposedly could do around 60mpg remember this is in 1989. http://en.wikipedia.org/wiki/Honda_CR-X
This guys results could get very close to that crx with the right things done to the car.

it does about 2750 rpm at 100, they were 205/55r15 tyres with 40psi in them and yes it was a brim to brim, could see the fuel level in the filler each time.
If I put the 3.8:1 diff gearbox in it would do better but Id rather it have more get up and go than get that last drop of fuel savings. SR16VE cams would also help with economy because they have less lift and duration on the low-lobes
Sounds like those falcons can be pretty economical too considering they are quite a large car with a big engine.

Interestingly, this wagon got as good of an economy figure was the 1.6L sentra could, its 90hp more and weighs 300kg more too.

Believe me, those mileages are well out, Dunedin to Clinton 96k, I wish. Never mind, just saying.

Its about 150km to dunners and about 60kms to invers from gore so he wasn't /isn't that far off. It depends just where you start counting tho. Plus theres and odd bit at clinton heading south where you do about 5kms in the space of 20m according to the road signs.
