Guys, I'm sure it's been discussed, but can't find any topics...
How hard do you guys drive your brand new cars? Do you keep them
under 3000RPM for 1000 miles? I always try to avoid a constant speed
with a brand new car, but go sometimes up to 4000-5000RPM...
How careful do I have to be with a 550i?

Congrats on the car! You'll love it. You can't go wrong with Carbon Black!

No my 545 was not sluggish,but my 550 is sluggish compared to my 545.I will quantify better after break in.I made many 0-60 runs below 5 secs in my 545.I will be very disappointed if I can not better my 545 times.I am speaking of the throttle response in the 550 from a start.It does not respond as quickly as my 545.I expect this to improve with more miles.
I now run it in manual sport mode a lot. Starting in 1st, it is very nice off the line but still not as quick a throttle as the 650i was or my '02 M5.
Re break in, I have posted before that I did an "accelerated" break in with the 550i. I stayed below 4500RPM for 500 miles but began to have a little fun with it on a mountain trip. By 80 miles I was hitting 5500 RPMs occasionally and still allowing the car to vary RPMs and load in the mountains. Bt the time I got back home the car had 1200 miles on it and felt very good. It still does.
Also, once I passed 1200 miles, I didn't let all heck break loose and take it to redline every shift. I waited for a track day at 3000 miles for that

I don't know how you're establishing your 0-60 times, and what errors are in the data, but just a thought about the throttle response of your 550 from a start. Do you have the automatic trans? Try the comparison in manual mode, if you haven't already. I didn't realize iinitially, but in automatic mode you're starting off in 2nd gear, not first.

I do have the step trans and always use the manual mode for testing.I am aware that the step sometimes starts in 2nd gear,but thats not what I am talking about.I mean it is sluggish for about 2 seconds and then seems to go to full throttle in any gear.It may be just a function of break in.

only in normal "D" mode. In sport mode ("D" + sport button) it is entirely different car, very responsive and feels definitely faster than 545i.

In D mode, for sure, you're starting in 2nd, hence the difference.

I've done only 250 miles so far. Hope it just needs more miles to break-in.
