also, just wanted to add that if you use the power ect switch it does make a considerable difference in gas mileage. i noticed about a 2 MPG loss with the power ect switch on. there is a noticible performance difference with the switch on so im assuming that along with a more aggressive shift pattern it also has a more aggressive fuel and timing maps which uses more gas.

I've got the 250AWD...

All highway I get around 26-27, as high as 29.
50/50 around 21-24

4000 miles so far, car avg says 22.0

I've gotten as low as 18/19- that is using the sport shift about 90% of the time, which means agressive driving, higher rpm's- etc.

I see very similar numbers as shaolin -- about 350-400 miles off a full tank, which means somewhere around 22 MPG. Somehow this isn't surprising, since we live in the same town...

Why doesn't one of the mods just STICKY a MPG thread?!?! Why have this place littered with thrads from the same topic??? Just sticky a MPG thread so people can just all post in that one thread.
