I just love my Tig more and more!

Picked her up 2 months ago yesterday, and have put 2070k on the clock. I've only just had to fill her up for the second time this morning (had a full tank when picked up).

Pretty impressed, over 2000km on two tanks.

[Transporter]

That's great; can you give us more details?
Do you do a lot of hwy driving?
And what is it in L/100km? If you keep record, of course.

[NZTiguan]

That's great, the best I've got out of my Tig on a run is 6.6l/100k or 43 mpg (imp) but that won't get you quite 1000 km a tank (tank is 64 litres so you'd have to average 6.4l/100k (over 44 mpg (imp)). Mind you mine was on some pretty windy and hilly roads including crossing the "backbone" of the South Island twice so I guess on flat going it would be readily achievable. Great work though, would be interested to know what your driving conditions were.

Cheers

I assume that's diesel figures you're all quoting.
My 103 TDI does about 7.5l/100km on the run to work in medium traffic but 6.5l/100km on the run home, Consistently. I can't explain the difference, the traffic conditions are a little worse if anything on the return run. It maybe that it uses a lot more fuel when its cold in the morning. Summer's coming, I can check the theory then!

[NZTiguan]

There's no doubt that "accessories" suck up fuel. I saw an interesting doco on sky a while back using a BMW 5 series and comparing fuel usage vs air-con, wipers, heater, headlights, air temp etc etc and when they were running at night in the cold and wet with everything operating it used something like 15% more fuel, the figures were quite a shock. I don't go out of my way to drive economically and so the figures I've got out of the Tiguan have really impressed me.

Cheers

Did a 450km round trip on the weekend 2 days after i picked it up almost half highwway and half city driving and averaged 8.3l/100km

thats in a TSI147

few more tanks and will have a better idea

[WannaTig]

Yep, in a diesel.
Has done a bit of highway driving, trips to the border and back. Also some short runs around the burbs. I'm kind of a nanna driver so maybe that helps go through less juice.
Now I've done the sums: over 2000kms on about 120L of fuel means less than 6L/100km which seems extremely conservative. When I've kept an eye on the consumption bizzo in the MDI it's usually around 6.5-6.8.
Not that I'm complaining!!!

[Sanman]

There are two average fuel meters -
ø1 which records the fuel consumption on that run ( reset if the vehicle stops more than 2 hours) and
ø2 which records the fuel consumption since last reset (or self resets over 9999 hours).
Its not clear in the manual, but ø2 can be reset by holding down the OK button for a few seconds. This means you can use it to record the average over a tank of fuel, or reset it after you've run in the car to get a better idea of the long term economy average (I tend to reset it when I go on longer trips)

[Arctra]

I have an admittedly very heavy foot and at the time of this post am averaging 8.5L/100km's over 10,311km's of driving. God only know's how it'd be with the more powerful petrol... I know the theory goes that because it has more power I might actually be more efficient, but I am honest enough to say that if you give me more power I'll use it anyway, and so am unlikely to be any more efficient.

On both our VW it resets after 99 driving hours, would be great if you could get over a year of driving hours logged.

Must have program for these who record and keep eye on car’s fuel economy and other car expenses. It’s free and it is good, it could also be used as the logbook.You can also use it for more than one car.

We have done just under 1800km and should get at least another 100 - 150km out of this tank. We are averaging 7L/100km. Its mainly highway driving with a little bit of city thrown in. So far I am extremely happy with the consupmtion and only hope that it improves as the motor is run in.

I know the TDi's are good, but 1900k's out of a tank?

[T&M]

Ours is the TDI103, I reset both of the consumption readings yesterday as I was driving the car through city traffic, then non-peak traffic, then the run out to our place a few times, picking up the kids, going to my Wed night sport etc... the best I got the whole day (option2) was 6.4L/100 which includes a bit of hill terrain as well. The best I got out of any one single trip was 5.2L/100 where I was on 80kph roads just cruising along quietly for about 30mins each way. Sink the boot in and keep the turbo on boost for a few minutes and it changes pretty quickly though.

Considering the car has only done 1500km, can't wait to see how it goes fuel economy wise when it has run in.

[donweather]

I must have the V10 version then as I'm down to a qtr of a tank and only done just under 400km. Then again I didn't buy the petrol model for the fuel efficiency.

I'm guessing all you guys quoting the amazing figures have the diesel models.

Although I'm questioning the 1900kms out of one tank....that's down to 3L/100km....can't say I've ever heard of the Tigs (even the diesels) doing those numbers?
