I thought the point of the tt v8 was to increase fuel economy?? i guess its worth it to wait and see what the next model does with the transmission and such.

Didn't you know that dumb questions
are not allowed.........:D

Ugly mpg numbers for the XM...
Cool X, lots of power, but those are exotic car/guzzler
numbers. Jeesh, the worst tank I've ever seen in our
'02 Vette was 24. Weight is the tripping point, I suspect.
GL,mD

Not in my case. I'm at 12.5 mpg with the twin turbo V8. I never got that low on my E70. I'm hoping it will get better over time. I don't quite have 2500 miles on the clock.

yea exactly i averaged with mild driving 18 in my 4.8i

Considering the 555 HP I dont think the mileage is all that bad. a mile worse per gallon on average than my E70 4.8. It is what it is. You are not buying this thing for mileage your buying it for driving satisfaction. Still better than a Lancruiser or LX570 or even Sequioa. And I'd like to see any of those things do what my M can do. But I know, there are things that those will do my M can't the difference is I don't need to do any of those...

for those who have the means to buy/lease/finance the X5 M, do you really need to worry about MPG? it's "almost" a supercar.

Look at what mileage owners of the E60 M5 were getting with the naturally aspirated V10. Then add 1000 lbs or whatever the weight premium for the X5 is. I think the twin turbo V8 is showing significantly better mileage than that hypothetical number.

At the end of the day, mileage will be very similar to an E70 4.8, until you put your foot in it. Then all bets are off.

I put my foot in both. Right now with 2500 miles on the clock I'm getting 12.3 on the TT V8 in my 50i X6 with performance upgrade vs 13.8 or so on the E70. I do have 90 more horses. I'm not complaining, just saying. Again, no ///M here, but I do have the TT V8

thats not the point, people like to know.
the biggest "worry" is the inconvinence of stoping at the gas station so often.

I also think that people that can afford a car like this, probably do care about the fuel consumption AND the cost of fuel.
Just because you buy a super, expensive, car doesnt mean you want to waste tons of money on gas.
