We averaged 7.2 in our TSI yesterday, over about 400kays. I was very happy with this as included a fair bit of driving in Brisbane and some stop start on the freeway, plus air con about 1/3 of trip and 115-120 in 110 zones and 108-110 in 100 zones.

This was from the MFD, previous experience shows actual was probably more like 7.5.

I got 4.8 coming down from the Blue Mountains from Mt Tomah Bells Line of Road, Richmond, M7, M4, to Lilyfield. And that was with roof racks on.

Now that is awesome!
Love the smooth downhill runs with limited traffic.

7.4 on the second tank (pump avg). 1st doesn't count as it was filled in by the dealer...

But I can feel the car is running looser now. MFD avg has already dropped to 7.5.

My 125TSI DSG gets about 8ltr/100kms on average, very impressed with that.

Is that babying it?

I gave mine the beans on the way home this morning and maxed at 9 but the average was 8.

Just normal driving, definitely not granny driving though, I reckon the car can do 7.5 if i really drive like a granny...

Granny driving should be able to net you low 7's
The best average i have seen in mine was 6.6 but that was highway driving in 6th gear.

Well I don't know what I'm doing wrong. Did 2 trips to the coast, and the remainder was city driving, and just calculated I did 626km with around 8 litres left in the tank (ie 56 litres of fuel used). So doing the numbers, that comes to around 8.9l/100km. So I'm still dumbfounded as to how some of you guys are achieving under 8l/100km in a TSI for city driving??

[team_v]

Babying it really helps.
If you have the cruise control on and make sure the needle hangs below the 2000RPM mark you can get great figures.

If you really want to get low figures pop it in neutral whenever you are going downhill (probably not safe or anything but the average fuel consumption then is 1.1L/100km lol.)

not only on hills and yes but only part true. On steeper hills you are actually better off leaving it in gear, as on 'full vacuum', the engine mgt system cuts fuel to the motor almost to zero, as is the case in almost all modern cars. So whenever you are free to coast your speed down or on moderate hills better to coast, but on steeper hills better left in gear. However if you could gain all the speed from the descent and coast back to crusijng speed on the flat, then better off in neutral in all cases.

I got 7.3 going into town and back today, including some hills and giving it the gas in third to waive goodbye to a holden ute behind me! This was only about a 9k trip and starting from cold. However I also cruise thru the residential area @ 45-50 in 4th and keep it in fourth down to 40 and I cruise at 55 in the 50 zone in 5th gear. I also roll a bit where it doesn't make a difference (ie going to slow down soon so I just start that a bit earlier and coast down where traffic allows. This driving suits me as makes no real difference to when I get there and most of the time I am constrained by traffic in single lanes anyway, so why rush. But not for everyone.

My local APR guy has quoted me a 10% increase in fuel efficiency if driving 'economically' using their map! I reckon if i sign up now, it will have paid for itself in no time!

I'm currently on an all-time average (city driving mainly) of 9.8, but i have got a 7.8 on a 15km freeway run into town on occasion. And thats not putting it into neutral down hills!

Post APR fuel consumption figures when driven for those conditions are generally better.
Normal driving (no babying but also no flooring it) will net me between 7.3-7.8 for city driving.
Babying it to the max can net me 5.5l/100km lol.
Flooring it will generally give back a 10l/100km result if i am on the gas all the time.

Team V great to see our respective experiences are confirming each others figs. Good job on the city driving av, but assuming your city driving doesn't include much stop/start? I've got those kind of figs in 'city driving' but not with a lot of stop start - which just kills fuel economy.

on the 5.5l/100, can see how it can be done (spot fuel consumption with crusing in 5th @ 55 is in the low to mid 5's) but have you actually got that as an everage for a trip? I always find it ironic that in using the crusing at low speeds in 5th strategy thru country towns (which fits well with normal traffic flow) that my 'hwy economy' actually goes down!!

I must admit, it's surely better than our diesel.
