740Li xDrive vs 750Li xDrive and MSport/ARS considerations

I need some feedback from those who have driven both the 740Li and 750 Li.

I have placed an ED order for a 2013 740Li xDrive with M sport and Exec Pkge.

I am considering changing the order to a 750Li xDrive. I live in Northern California and drive in the mountains a great deal so xDrive is important. I want "fast" but I also want efficient. The new 750 drive train has become much more efficient, there is no longer a gas guzzler tax. I just got my wife the F30 328i and have enjoyed putting the car in Eco Pro mode and playing a game of driving as fast as I can on the highway while maximizing fuel efficiency.

My questions are:

1). Is the 740 drive train slow? BMW says 0-60 5.6 seconds...is this downhill with a 20 mph tail wind and 110 octane or are these numbers real?

2). Does anybody have any data on the 2013 750Li fuel efficiency...driving 80 mph with AC on, flat conditions limited head wind?

3). I had a 2011 M3-the manual claimed i was electronically limited at 155 mph but I hit 176 mph on the autobahn. What is the difference in the electronic limits of non-MSport vs MSport? I am teetering on MSport-while I like the front end better visually of the MSport, you lose the fog lights and I'm not sure how much faster you can go (BMW claims non MSport limited at 149). The extra $$$ may be worth driving for a week with opportunity to hit 170 mph + on an open autobahn at 6 AM.

4. How noticeable is the ARS in a mountain driving/freeway on ramp situation?

Thanks in advance for your feedback.
