Nice write up and thanks for all of that info. I've been driving similarly using the different gears but not as extensive as you. When the time IS right, how do I do launch control from a 0-60?

Thanks and good question

So I haven't tried it and when I asked the Delivery Specialist at PCD he didn't even know the X6M has launch control. Understandable, they probably do not see a lot of these cars.

Here's how I *think* it's done although I haven't read manual or tried it yet. I did do it on a Panamera S I test drove a while ago and it seems to be similar.

1. Disable traction control completely (not MDM mode)
2. Put car into full manual mode (I.e., not just sport)
3. Hold brake pedal with one foot and floor it with the other at the same time
4. Revs build up and car gets ready
5. I am not sure how the car indicates its ready; if I recall in the panamera some light turned on. Either way the revs start to level out around 5k or something, again not sure exactly
6. When revs are stable slightly going up down a few hundred RPMs, release the brake and keep flooring it on the gas.
7. Hold on to your horses!!!!

I will update this sequence once I read the manual and/or try it out.

Edit: Disclaimer: Try at your own risk! Make sure road conditions are completely dry and you have a nice clear straight road ahead of you with no grandmas and baby strollers crossing the street, no cows just hanging out on the sidewalk - yes, I actually ran into this very scenario myself on Sunday morning in Parkland, Florida with a cow that got out of a farm somehow - and no airplanes doing an emergency landing, etc., etc.

Well ours is at 1060 miles so still a way to go before we stomp on it. We have been doing mostly city driving and a little highway driving and keeping it under 4k rpm. It has alrady consumed a half a quart of oil so make sure you guys are checking your oil level. I will not run oil less than max on this car given the huge turbos. I will start pushing it harder as I get close to and past 1200 miles.

Good advice! I will check mine also and see where it's at. Although I didn't check it before so I'd have to get a baseline first, then check again in 400-500 miles or so and see if it's burning oil.

Mine was at max from the factory. By 950 miles it had consumed about half a quart. The S63 is known for its oil consumption.

In M mode the truck takes off with quite a jerk, so engine braking may not be necessary for a thrill, but if you do want to engine brake, I would modify steps 5 & 6. Once you get up to your desire engine rpm, let is rip ASAP. This technique is murder on the transmission. Second, from my experience the time to punch the gas is when the first yellow light turns on and let go of the brake as the third light turns on.

Finally, at 120mph, take you foot of the gas and start braking.

Great information sharing, guys. The X6 is a sweet ride, wife almost talked me into it, but my heart is set on the M6. Still trying to get pros / cons on coupe vs. convertible? Thought i did a ton of research, but learning a bunch from u guys, appreciate it.

I test drove both the 650xi and the M6 and I couldn't see the M6 as a daily driver. It was fast as blazes, but the ride was a bit too harsh for my likes. I'll probably get the Dinan engine and suspension tunes to satisfy my need for speed.
