Official Fuel Economy Thread (formerly Highway economy).

[Transporter]

HI All

Recently picked up my 118 tsi and driven it about 1500km. Im a little concerned about fuel economy. Ive getting on average about
11.2lt/100km, which is a far cry from the state 6.9lt/100km. I do mainly suburban driving (NOT city grid lock driving), and am averaging about 550km per tank. Im a little dissapointed considering its a 1.4 litre and 2 whel drive and that I am a conservative type of driver. Is this going to improve with more driving?

It really depends from the traffic and how you drive. Remember almost every time when your foot is off the accelerator the engine doesn't use any fuel. The 1500km is too soon to get the best fuel economy for many; it can take 5,000km to 10,000km before you know the car enough to get the best out of it. By then engine will loosen up a bit as well. I'm sure you will get better fuel economy soon. In the mean time, enjoy it.

Thanks guys for your response, given me a little reassurance that better fuel economy is still to come. But despite that, an excellent car to drive. Ill be putting an OEM rear boot handle reverse camera in this Sunday (hopefully) so will try to take some picks of the process as Ive had a bit of a hard time finding info on exactly this type of install, plenty on the badge camera, and I know essentially its the same, but Im sure there are going to be some slight differences Ill have to figure out. Also managed to borrow a vagcom from brother in laws friend, so Im all setup for install.

Left my roof racks on this morning and drove down the coast, averaging 110km on the speedo. Noticed a considerably higher fuel consumption with the roof racks on....at least 1.5-2L/100km more. I was surprised it made such a significant difference.

[MGV]

What type of racks do you have, Don?
I notice a bit of an increase when my racks are loaded up, but negligible when unladen.
OEM looks less aerodynamic than my rhinoceros ones!

Lockable Rolas just like these ones:

Rola Roof Racks - Volkswagen Tiguan Wagon 5dr (05/08 on) - iRacks - Roof Racks and Accessories

Noticed a fair amount of additional noise driving with them on the highway also.....guess that's what makes the fuel consumption go up.

I've had ProRack Whisper bars fitted from day one so can't compare before and after but I don't notice any noise.
First half tank indicates 9.4l/100 which seems good to me

Headed down to Torquay this morning with the behemoth on the roof racks (recently taken up SUPaddling) & managed 7.3l/100k (on the way down)! About 100k's each way, maybe 70 of those doing 90-100kph.



Trip home wasn't quite as good as a northerly headwind had picked up through the day, but still managed 9.1 on the return leg. Sill good considering the additional drag!

Pretty happy with these figures, better than i have gotten before on fairly regular similar trips with a regular 7' surfboard on the roof... I'm wondering if the new hi-flow air filter i have just installed ie 'easier' breathing (& claimed torque gains), would result in slightly better economy?

Recently picked up my 118 tsi and driven it about 1500km. Im a little concerned about fuel economy.

Our 118TSI averages around 9.3L/100 around the suburbs with the leadfoot Mrs doing most of the driving during the week. Over the Easter break with mostly country driving and towing a trailer we got 7.6L/100. As the KMs are clocking up (6200 kms so far) I'm noticing a definite downward trend on the fuel consumption which is nice to see.

Heading to Blueys Beach in 118TSI manual. Mixture of L plate 80kms and me doing 114.
Roof rack with big kayak, 3 people and boot overflowing.
7.0 l/100kms and dropping with only 800kms on clock.
Very impressed. Will cruise in 6th gear at 1800rpm.

[Pinarelloman]

Ours now has 24800km on it. I have checked the economy several times and it always is around 16-18km/ltr. Very good.

[ido09s]

I have 4000klms on my 132TSI DSG Tiguan

Overall i have achieved an average of 10.1 litres to the 100.

Most tanks though will see 600klms from about 60 litres which adds up obviously

Pretty happy with it though i am hoping it does become a little better

Took the Tig out west for a camping trip, fully loaded up managed an average of 8l/100km with stage 2 active, and a mixture of 100/110 zones with slow downs to 60 for small towns.
Also had the aircon on about 30% of the time as it ended up being around 32 degrees.

[Mullos]

I've only had my Tig for a few days and love it....

Just wondering if these fuel consumption figures are taken from your trip computers, or a more detailed analysis is being done - ie recording miles travelled and amount of fuel purchased?


For what it's worth, my first week on the road sees me getting 9.6l/100kms in city traffic according to the trip computer.

Cheers, Steve

earlier posts in this thread have covered, most are probably MFD figs, but Team V's and some others may not be. In my experience from testing over 5-6 tanks the MFD in ours (stage 1) is about 0.2-0.3 optimistic. So a 6.7 MFD is more like 6.9-7.0 l/100. Team V and I have both got into the high 6's and low 7's on hwy trips (MFD), but that's running at 100 or just under, 110 will push it up into the low 8's.

Okay after the first 3 fills of our 155TSI, the fuel consumption after 70% highway driving is as followed:

8.7 l/km
10.0 l/km
9.1 l/km

Those figures were archived with permanent S-Mode, Aircon and overtaking only with WOT.
