Official Fuel Economy Thread (formerly Highway economy).

[team_v]

Did a highway trip from Northside of brissie to Dreamworld (65km or so each way, 50km each way highway)
Fuel consumption for the day was 7.4l/100km
Best i saw was 6.8l/100km in the 100km/h zone.


This was with 4 adults in the car + esky etc and about 25km of the trip each way in a 110 zone

Hmmm.... long term average calculated from the fuel dockets is the only right indicator of the real life fuel economy.

I understand that.
Just thought i would share the trip average to show that you can still get good figures even with some city driving nad modifications.

From my experience, the trip computer has only been between 0.3 and 0.5l/100km under reading over the life of the car.

I know that, but some people may think that they will get 7.4L/100km and don't realize how many short trips they do for one long one. Just watch the instantaneous fuel consumption while taking off and warming up.

I think that the trip computer is quite accurate in calculating the fuel economy and the error is there because of the discrepancy in the fuel quantity we put in the tank and what we pay for.

I hear you with that.
Instantaneous when you start her up and take off will be around the 20l/100km or so.
The interesting part is watching hte distance until empty reduce by up to 40km when you hit some sort of traffic.

Pretty sure I've posted this up before, but at present my long term average (17000km) is 11.4l/100km. I can easily get less than 7l/100km cruising on the highway, just like team_v .... but .... if you drive enthusiastically everywhere else you will get high consumption ..... I can not get less than 11l/100km on a 20km commute each way .... my wife however can get 9l/100km on pretty much the same commute ....

Same applies to a TDI ..... bottom line is .... if you use the turbo it uses more fuel .... My wife can get 10l/100km in the TDI MV where I get 13-14l/100km on the same 20km commute. I battle to get 500km out of 80l of pricey BP Ultimate Diesel.

In fact to get similar performance, I'd say a TSI is lighter on fuel than than a TDI

As soon as I sit over 100k/h it starts going up. Sit on 100 (true hundred, not what the speedo reads, which in my case I need to be indicating about 107), I can get 7.8, as soon as I push it up to 110 (indicating 118k/h) it increases to 8.2 at best. That's crusing down the Bruce highway, so no hills or silly business. Can't get away from the aerodynamics of an SUV I guess.

Got the Touareg 99.9L/100km when just starting to drive up the hill.
The Tiguan is a bit less, but still scary when you watch it.

... nad modifications...

YOWCH!! Sounds painful! Sorry, couldn't help it...

Just thought i'd chime in with a pretty good rate: A recent run up the Hume & Pacific got me 7.9 over 1350km's in my TSI. 60% at 110 (118 on the cruise = 110 on the GPS), 40% at 80-100. Loaded up removalist style & with a surfboard on the racks!

Also, as suspected by another member here, the long term average DOES (at least on my '10 model) reset itself every 100 hours driving time. 1st time it happened, i thought i had inadvertantly reset it, but i have noticed it happen twice since then. Mine usually makes it's way back to low - mid 9's eventually.
