I know this bad boy drinks gas, but is this right?

IMHO, The trip computer (ie, the indicated mpg or L/100Km for Canada) is unreliable to use to determine the actual range and gas consumption.

The figures displayed in the dash board are calculated in real time not over the period of one full tank. So one may be traveling over 700km on one tank of gas, occasional peaks in gas consumption can throw the figure up becuase it only shows the rate 'as of now'.

I drove about 150 km on highway showing 730km range initially but as soon as i drove in the city the car gives me over 18L/100km gas consumption, which is about 470km range on one tank at that rate. but since I drove 150km on the highway already, that puts me over 600km range per tank.

Bottom line? Best way to find out how much gas one uses in his or her specific style of driving is to fill up the tank to full, reset the trip-meter to zero and let the gas run out. That way, one can determine exactly how much he or she travelled and how much gas was used for that exact distance.

hope that helps and please lets not panic.

I use this site to keep track of my mileage. You can even keep track of different vehicles. Very iphone friendly.

13.1 MPG on my 2002 M5. (Yikes)

Awaiting a new X5 for comparison.

my current 14mpg SUV gets about 215miles on a full tank so that sounds right.

Welcome to reality! With a bigger engine & heavier body expect lower MPG.

I am getting approx 300 miles on a tank, in a mixed local/hwy driving (70% local / 30% hwy). It was much worse during the first 1000 miles, close to what has been reported in this thread.

It will get better, you need to let it break-in a bit and learn how to drive. I am watching instant MPG gauge, and see 20mpg on local driving if the road is flat.

On a recent trip upstate, I did 310 miles before a fill up, and could go for another 70 miles if not for the fear of not finding a gas station in the mountains on a weekend

uhh, did someone delete my post?

1200 miles and i am averaging 15/16 mpg. but have been light on the go pedal.

Wow 104 is the exact miles i got outta 1/2 tank too. Same driving conditions as you in a 4.8 with 300 on odometer rite now. I checked the trip computer after those 104 miles and was averaging only 11.5-11.6 mpg.

also did you notice how sluggish the car feels on standing starts?? I mentioned it to my salesman and he says all is normal for the break-in period and 1200-2400 miles is when the mad mileage and sluggish starts go away, lets hope he's rite

Speaking for my experience, your salesman is right.

Ditto... It is much more responsive now, and mileage seems to be improving (1800 mi on the odometer)
