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.

You sound experienced, nice! And Hahahaha at your disclaimer!

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.

I picked up my X6M at PCD on Thursday and asked several people about this.

Even though our X ///M engines are similar to the new M5's and M6's, the transmissions are obviously completely different. Apparently the M automatic transmission in our cars doesn't need as much babying. There is no 1200 mile service according to techs and the manual. The car does not indicate one in the settings menu, either. That being said I am still thinking I may do an oil change around 3000 miles.

Now, there have been lots of questions (not necessarily in this thread) about our cars being ran on a dyno at the factory to the hilt, etc. I asked about this on the factory tour, as we passed by the place where this happens. It's actually not a dyno, because it does not measure horsepower or torque; however, it's otherwise a similar device. They called it a treadmill. I was told they do not run the cars to redline, they shift early, but they do run it to maximum speed of the car. So our X ///M's were ran to 155mph, apparently.

I am not 100% familiar with the gearing yet, so I am not sure what RPM's it takes to be at 155mph in 6th gear in an X6M - anyone who's tried it, let me know Suffice it to say I was told what they do at the factory doesn't constitute or replace a break-in of the engine how you will be driving it after 1200 miles - lets face it, otherwise we wouldn't have bought an ///M!

For my break-in (completed 1148 miles within 2 days of owning the car and then hit 1200 on the morning of the 4th day ) I went along with their suggestions of

- 5500 rpm max
- don't floor it (avoid "transmission kickdown mode", something I learned on another forum)
- no cruise control or constant speed
- do not exceed 100mph (I have a feeling this is for us, not the car)
- various road conditions, stop and go traffic, mountain roads, used all gears in all RPMs up to max

I did exceed 5500rpm a couple of times accelerating and neither confirm nor deny possibly having exceeded 100mph here and there As I passed the 500 mile mark I started using more heavy throttle down to 3/4 and then, nearer to 1000 miles, close to, but not quite flooring it. Since I was also driving in manual mode the whole time - because why not! - this helped avoid the kick down mode. Always linear buildup of revs in the current selected-by-me gear.

As soon as I hit 1200 miles, I opened her up gradually to 6500 RPMs in 1st and 2nd gears, then 3rd and 4th on the freeway while entering or passing for some brief moments. Holy mother of god! Let us just say that entering and merging onto a freeway is nearly as easy and quick as on my Ducati Diavel 162hp (0-60 in 2.9 seconds, some say 2.5 actually, either way, it's FAST) motorcycle! I still have not really floored it, done a proper 0-60, used launch control, or pinned it for long periods of time. I am gradually introducing some more aggressive driving as the miles tack on.

My car still doesn't feel quite as aggressive as the X6M I drove at the PCD but it's getting there. I got to stomp on that thing in 1st gear to the floor and we devoured the tiny front straight at BMWs handling course in what I could only describe as warp speed. It was unreal. Couldn't even floor it in 2nd completely or we would've been off the track! That car had just over 10,000 miles on it. The PCD guys did confirm that the M cars at the BMW Performance Driving School don't go into full duty until they're at 1200 miles.

All in all, this thing is such a beast that even during break-in there is no shortage of power in almost any gear. Passing almost anyone after a quick downshift from 5th to 4th at 80mph brought my self-defined 100mph "speed warning" chime REAL fast.

In summation, this car freaking rocks!!
Hah! awesome writeup.

Considering I could only put 29 miles on mine after swapping my '11 50i for a '13 Silverstone X5M, this was an entertaining read. Leaving it at the airport for a work trip was not easy.

Miles of goofy smiles ahead tthough.

Also, the manual says not to exceed 5,500rpm for the first 1,200 miles whereas for the 50i limit is 4,500rpm. I thought ///M engines had strict babying rules when new, but it seems to be just the opposite. Any thoughts?

You can always pay for an oil change out of pocket at the dealer.
