Your wife will prob get it lower anyway.

I get 350km from a 65 litre tank normally. If i drive craefully i can stretch it to 450. When my fiance uses my car she can get around 550km.

Dont know how she does it lol

Having owned a 5 pot ST myself fuel consumption went out the door. I tried granny shifting for a week and couldn't take the pain no more even so my consumption wasn't anything to brag about. 5 pot is thirsty and with a small fuel tank in these cars that doesn't help either.

They say a BT will be more efficient than oem because of the late spooling ? But also heavier if your foot is heavy.. is this true on a 5pot ?

Yes it is, a heavy foot means more boost which equates to more air entering the engine and thus more fuel required to in order to keep to the air/ fuel ratio required.

To explain it, when you are not boosting you car will aim to run an AFR (air to fuel ratio) of 14.7. As soon as you start boosting this ratio drops to around 11 to 12 depending. That means that you are already using 25% more fuel by just going into boost, but as soon as you start boosting the airflow will increase as well which now increases your fuel usage to around 40-50%.

Better fuel economy on a BT is bollocks purely because you're going to want to boost ALL-THE-TIME :lol:
Now, I admit that there are two distinguishing features that you can use to tell apart the Audi sedans. One is LEDs. The A4 has roughly seven, while the A8 could guide damaged ships to the mainland.
