  • hi all
    just digging up this thread again.. we've done about 1000kms on the tiguan... so far average is about 11.1 L / 100km... this was about 95% driving through suburbia .. tbh i was expecting alot better!!

      I had similar experience with my wife's Mazda 3. It took around 5,000 km for everything to wear in/ loosen up and since then it's been better.

      • I'm still disappointed with my 132 TSI, best I can get is 8.4 ongoing average and that's with 90% highway km's and not thrashing it

        Considering getting a tune just to make things more efficient!

        Edit: I should add that 90% of the time it's just me in the car with no additional luggage or anything and running on BP Ultimate 98..

        • Well I did a reasonable (500km) run on the highway yesterday in my 125TSI with stage 2 tune and returned 9.9l/100km. Though that was sitting at 110km/hr (SA) - economy is worse at higher speeds. Plus it was wet... but not sure how that effects things. I wasn't trying for economy figures - just reset the averages at the start of the trip. Also gave it the occasional spurt just because I can

          I don't think your fuel economy is that bad. Remember you have a 1600kg car and AWD system to lug around so it's pretty reasonable... Plus aero disadvantage with a larger car.

          • Hi Just an interesting one, have never seen my range this high before (Tig MY11, TDI DSG),

            Note I had already done 79 km since fill, I know this can be inaccurate but even so its a big number. Will qualify and say I had done some downhill driving (for those in NSW, Lithgow through to Richmond), but I held 4.7 l/100 average through to the Central Coast (through Castle Hill, Hornsby, not M2)

            • Def thinking of stage 1 for other reasons if it helps the fuel is an added bonus for sure

              • Well on the return journey I achieved 9.3 l/100km. I did drive a little more "conservatively".

                Having said that with a stage 2 tune and an exhaust where you get DSG farts on gear changes it is far more rewarding to give it a few more beans

                • how the hell does it get combined 8.8l / 100km ??

                  no where near that..

                  • Fuel economy is an interesting topic. The largest differences are due to driver input more than anything else.

                    I keep logs of all my cars as well as a mixture of work cars. You will find that city driving is a huge variable as well.

                    What are you describing? Bumper to bumper peak hour city traffic or after hours suburban driving. I have found huge variances for both.

                    TSi engines though tend to give a more stable figure than TDi's in the city.

                    The now permanently wife owned Tiguan 155 will average 12.5l/100km - 13.5l/100km on a short 20min drive to work and back where as in my hands (or rather feet) it will average 11.5 - 12.5, and by granny driving (no offence to any grannies) I can bring that down to 10.5

                    Taking this car on weekend escapes and on carefull applications, I have seen as low as 7.5l/100km over a 1000km distance and can easily go up to mid 9s for a slightly more aggresive driving.

                    The diesel Amarok though will match the Tig on drag racing style city driving (can't help it as if you give someone is Sydney half a chance they will race you to get in front of you) but will easily go below the Tig on country drives.

                    The diesel Caddy though can easily return mid 6's and sometimes even high 5's on easy city driving and mid 8's on bumper traffic.

                    Toyota Hiace diesel will give you quite a wide range of economy figures as well.

                    The only car that had metronomic economy figures was a 1996 Honda Civic, which for some reason whether driven sensibly or thrashed would still return an 8l/100km figure.

                    The key here is turbo and non turbo. Turbo cars (diesel and petrol) will have a large variance in economy depending on how you drive them and on traffic conditions. Remember take off and using only 10-15% throttle applications will make really good figures for economy but how long you can hold out on with other traffic pushing all the time is a different story.

                    Aircon use, usually, raises the economy figure by about 0.8-1l/100km roughly

                    All figures taken with fuel entered and km travelled and not MFD

                    • agree re driver input, tyres will also make quite a difference. I have never bettered our orig tyres (Hankooks) even tho I have tried some 'low roll resistance' tyres since.

                      IN our stage 1 TSI (190kw) I used to be able to readily get into the mid to hi 6's on long drives at a steady 100 without air con (MFD which is optimistic by about 02.-0.3 l/100 in our car) but I struggle to do that now. Our long term mfd av is about 8.5, tho thats with the Mrs driving, it would be under 8 with just me, tho I give it a squirt, I dont use air con much, or go much over 100 on the freeway and I coast where I can, slow down gradually etc, all of which helps with fuel economy.

                      I was also disappointed with our initial economy but after the first 1000 it improved.

                      Speed also makes a huge difference, at around a steady 80 even in the tsi you can manage into hi 5's on the mfd (so hi 5's low 6's real), whereas at 120 (indicated) i'd struggle to get below 9.0, so there's over 50% difference just there. That fuel economy at 80 is great, but unsustainable on long trips esp single lane roads (as apart from our own impatience you'd spend a lot of time pu;;ling over to let others pass or worse.....you become one of those drivers who ignores everyone else and holds everybody up!)

                      • The biggest fuel economy factor after the way you drive it with the Tig is the fact that it's got the aerodynamic efficiency of a brick. On the open highway the fuel consumption figures are subpar in my opinion. I average around 8.4-9l/100km (APR STG1) driving at 110km/h most of the time. I certainly don't recommend this, but as a test I followed a friend very closely on a 250km trip on the open highway, he has a big landcruiser. Anyway, I topped off when we arrived at the destination and I achieved an average consumption of 6.5l/100km. I know when you decrease drag your fuel efficiency improves, but by that much! I have a friend with a 2.0TSI Q3 and he gets about 7.0L/100km real world and it's heavier. This is the sort of figures you expect out of the Tig but it's just not shaped correctly to achieve those numbers.

                          Well today as an experiment I took the roof racks off and got 9.4 l/100 on a 600km trip just driving "normally". I don't think there's a big difference - perhaps a saving of 0.1-0.2 l/100 if you're lucky. Though the racks I have are pretty aero.
