Even a diesel has poor consumption of you use the turbo excessively. When the turbo makes significant boost the ECU dumps more fuel in ..... and out the window goes fuel savings. I have a friend with a GT TDI Golf and he drives it like he stole it. He gets worse fuel consumption than a female friend who baby's her GTI Golf .....

I once had a 103TDI Golf as a loaner for a day and my average consumption over 90kms was 11.1l/100km ......

I'm finding some of the figures a little confusing too. I have a heavy foot, I admit, and so far am averaging 8.55L/100km's. The best I've seen the Tig do was my girlfriends very sedate driving to Caberra and back which averaged just 6.7L/100km (worked out from the refuel and trip meter, not the onboard computer).

FWIW ,
my best is 6.85l/100k on my returmn trip fromm the gold Coast
average since new 7.38

figure in classic manner using odometer reading and tank fillup anounts total 9779 kms

I know you know what it stands for.

go find hte youtube vid of the topgear back to back tests between the 5-series petrol and 5 series diesel.

[team_v]

Couldn't dfind the topgear review on youtube but i found a 5th gear petrol vs diesel.

This is why i am going the petrol way.
Also the chip increase

By BSFC you mean Brake Specific Fuel Consumption? http://en.wikipedia.org/wiki/Brake_s...el_consumption

And are you referring to this video?

I take it as the time honoured saying ...... boost scr3ws fuel consumption .... it applies no matter what car it is .... diesel/petrol .... all of them use more under boost .....

EDIT ... that 535d used 19l/100km ..... LOL

as Jeremy would say "what a load of bollocks". More Top Gear rubbish. Put those same two beemers head to head on a dry track and the petrol would have been even further ahead - much further ahead.

Yes, TopGear have a bad history of manipulating results of their comparisons ..... Veyron & Maclaren F1 recently prime example ......

This makes sense to me. Most of my driving is inner city and if I drive my 147 the way I like to drive it, my fuel usage, fill up to fill up, is consistently in the 15s l/100kms.

Must be that auto messing with consumption. My 190kw Tiguan driven VERY enthusiastically in the city is about 13l/100km at the moment.

Open road stretches has returned in the 7l/100kms ....

[Pullstarter]

With the chip I also get about the same around town Johan, certainly not driven easily either

P.S. Nulon Pro Strength Octane Booster is gooooooooooooooooooooooood!

Sounds as though you drive similar to me. I just filled up my after first tank. Average consumption (based on computer output not fuel input) was around 12-13 L/100km
