That is 9.5l/100 km which is better than the 550 xdrive and better than the 22 mpg C&D is reporting. Of course, if you are hitting launch mode every day, the mileage will suffer. In any event it is beter the the 11 mpg city the E60 M5 was rated at.

As to the N63/S63 fuel economy, BMW engineers have been quoted as saying the there are some design changes in the M5 engine that will filter down to the 550i and other engines next year which will help with fuel economy. The N/S 63 engines don't hae the technology yet.

In any event, I'd pick a stripped (but still very well equipped M5 before I'd get a loaded 550. I'm not really into soft close doors and can live without dash leather on the M5.
And like I said, impossible for the M5 to have better gas mpg than the 550i.

It now officially has a $1,300 gas guzzler tax. Full order guide @ http://f10.m5post.com/forums/showthread.php?t=682808
