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
