Fuel Efficiency

[Rooboy]

140tdi and currently sitting on 5.9 l/100k around Sydney, did a trip yesterday western Syd to hurstville rtn and averaged 5.1 L/100k. I can't believe how economical the 140tdi is and it's only done 1000k's. I really expected mid 6's and tbh if the cars running fine don't care how much fuel it uses.

I doubt there would be much difference between the Tiguan and Passat Alltrack when it comes to fuel economy, very similar weights.

It's not just the weight but the aerodynamic efficiency which puts the Tiguan at a slight disadvantage. The official numbers for the 140tdi are 5.9 in the Tiguan versus 5.4 in the Passat Alltrack.

Have got my Tig in for it's first service today and long term consumption, travelled 14,850Km since pickup, is 10.3/100Km. I track every fuel purchase and KMs in the app Fuelly.

I do a LOT of driving in heavy traffic and short trips so pretty happy with where it's at, plus it's great to be able to give it a blat from time to time and blow out the cobwebs

I also use fuelly to track consumption as I find the car's read out about 5-10% optimistic.

Point taken the Passat appears to be about 30 kgs heavier but is more aerodynamic so that would be a definate advantage. They are both quite frugal in TDI guise, it was a hard choice between the Tig and Passat in the showroom.

Have a 132 Adventure, fuel economy is in the low 9s. Mostly city, start/stop driving with some freeway runs. Aircon run 95% of the time. Driven approx 3000km.

I've done a long trip recently expecting to get around 7-8's for the long trip, as my mk7 gti was around 7 on the same trip. On the way there it was 10L per 100km, on the way back it was 8.9L see attached. No chance of doing it on one tank.

That's not too bad! I've been averaging 15-16L per 100 lol

I think I need foot control.

Yes indeed i have the same issue lol

My diesel does 7.5 to 8ltr/100 when everyone else gets 5.8 to 6

If you find the foot control let me know

This car is getting better economy with age I think, just hit 10K. pushed it to 850km this time.

I have a 2017 162 TSI Highline. On a trip from Sydney to Melbourne using Eco mode I approached a displayed 6.7 ltrs/100km when I filled up in Albury. But when I did the calculations it turned out to be 7.2 ltrs/100km. Still respectable, but 60 litres will not get me from Sydney to Melbourne on 1 tank.

For the first two tanks in my 2nd hand Tig 110TSi Man (now approaching 14,000 kms), I have indicated 6.6 but actually measured 6.8l/100. Still very happy.

I have just done my first monitored refuel of the 140TDI Tig. Total kms - 536, 34.9 litres = 6.5 litres / 100kms.


This involved 300km driving from Canberra to Sydney plus 236 driving around Canberra.


I monitored the trip to/from Sydney uing the AID. For both trips I had ECO set plus I used the ACC set at 110. For the trip to Sydney I achieved 5.6 l/km and from Sydney to Canberra I achieved 6.1 l/km.


This small difference is actually important. The trip to Sydney is downhill. This means there is many more opportunities to use the 'coasting' feature of ECO. I believe the coasting is probably the most significant contributor to ECO fuel consumption. When driving in Canberra it is surprising how many times the car will coast and when it does you can see the average consumption go down.


I think the coasting is more significant than changing up the gears early, and more significant than the start-stop. It would be interesting to hear others experience and comments.


Using 5.6 l/km for the trip to Sydney we can work out that for the 236 km in Canberra there was an average consumption of 7.6, which is probably about right when compared to the average consumptions being displayed on the AID.


Overall I am very happy with the fuel consumption so far.

I get 8.0 in Canberra with my 140tdi. Have done 30k so far.
Canberra Sydney is normally 6.4
