After I signed my papers this past Wednesday, the finance manager walked up to me and said the same bullshit. I just let it go.

He also told me that the car was so special, I would need the full warranty, because oil changes are very complicated. "All computers" is what he said... smh... Nice guy, but fuck.

You shouldn't be going high revs on a car that's not warm period.

You aren't going to break anything. But you shouldn't make a habit out of it, and avoid if possible.

I was driving in the rain yesterday, and I had to accelerate to get out into traffic, car lost it and RPMs went over 5.5k. Shit happens.

I am neither for nor against following "recommended" break-in. But my own life experience suggests that:

1. if recommended break-in could be proven to be even mildly effective at limiting factory warranty claims or improving long term reliability ratings, it would not be left up to us idiots to decide whether or not to follow them.

2. In the US, there is a decal permanently applied to your visor because consumers are stupid and don't read the manual. Why would manufacturers trust us to perform a critical break-as outlined in the manual.

3. The most egregious purveyors of "fake science" HowStuffWorks, Popular Mechanics, The Car Connection, AutoEvolution, The Hartford, Engine Labs and even Subaru of America all subscribe to the best recommendations for break-in restrictions but at far shorter periods. As little as a 100 - 500 miles. All while being completely immune from the wrath of outraged Engineers. NOONE is immune from the wrath of outraged engineers EVER.

Once more, I am neither for nor against following "recommended" break-in.

Appreciate the feedback. I think I'll be fine; I was well below the recommended 5500rpm limit and it was a gradual acceleration, steady, but gradual. Not like I stomped the accelerator and went WOT.

Your tach will tell you the max RPMs at your current engine temp. And if I'm not mistaken, you are WAY below the max at 4,800 RPM for an engine not fully warm. So yes, you are being crazy

You guys, let this go. Drive the car. Enjoy it. It will be fine.

Just got back from a test drive, told the salesperson that I was underwhelmed with the power. I was told that they plug something into OBD port and unlock full power at the break-in service.

Sounded reasonable to me, but everyone on these internet forums is calling bullshit.

Does anyone have any actual information about this? Before/after dyno would be interesting and more convincing than a bunch of internet experts incorrecting each other.

I found this, which seems to agree with the "bullshit" angle: https://f87.bimmerpost.com/forums/sh....php?t=1544580

Also found this, which seems entirely reasonable:https://f87.bimmerpost.com/forums/sh...9&postcount=12

I just completed my break in period, did not exceed 5500rpm, did not go full speed LOL, but touched 180kmh a couple of times. Fine. It's called breaking in. Not laming in. This evening my 275km weekly commute, finally right foot touching the carpet, compared to my F80M3, the M2C is scary as shit on the wet. Loving it Already looking forward to Friday going home

Engines don't need a break in period anymore. The rings are set when they run it in at the factory. You're breaking in the rear diff.

Wrong. They don’t break engines in at the factory, they don’t even hot test them. Some samples will be tested for quality control purposes but they are certainly not run in.

There is a reason manufacturers still recommend a 1200 mile break in period. I think BMW’s engineers know more about their engine, it’s materials and manufacturing tolerances than the vast majority of people on the internet!

At the end of the day though it’s your engine so make your own choice.

Hmmm, I'm not so sure "BMW engineers" wrote that requirement. I suspect that a lot of parties were involved - most notably legal and accounting. Cause if you want to put your trust in these "engineers" and they were the ones who "wrote the manual", then they are also the ones saying you can go two years/15K between oil changes*, the trans fluid never needs to be changed, etc.

The fact is, the tolerances are much improved with today's engines and most do not require the "gentle" 1,200 miles that BMW recommends (and then I think they say take it easy for the next 2,000 or so miles or Kms AFTER THAT). A little crazy....

Of note, the brakes however do need to be broken in

But the fact is, too many people go crazy with their brand new cars and end up messing them up big time - I personally think that's the biggest reason for the break-in requirements - alas, it is one of those things that can be a fun and never ending discussion here and on the interwebs.

*early versions of included maintenance only called for oil changes every two years/15K - in fact, as soon as BMW started paying for maintenance, suddenly their requirements changed Of note, my 1995 325i had a 1,200 mile service (as did all BMWs I think) before BMW decided that only M cars would get this. Engineers changing their mind? Or Accountants getting involved

They changed engine oil as well. Whats the use of 5500rpm max if you only break in the rear diff ? Then it should be max speed only to be honest. What I do not understand is that by no means the car was restricted. Pushed a couple of times till full boost to let the torque come in, went like any normal S55.

You aren't going to break anything. But you shouldn't make a habit out of it, and avoid if possible.

I was driving in the rain yesterday, and I had to accelerate to get out into traffic, car lost it and RPMs went over 5.5k. Shit happens.
So I'm one of those idiots who neglected to read the manual and after 200+ miles of driving how I feel the car should be broken in, I have done a few 3rd (mt) wot for a split second pulls up to around 5-6k rpm and about 100-110 mph pulls. I'm now looking into "how to properly break-in" my CS. It doesn't seem like I've punished her to bad yet. So I'll baby it a bit more for the next 1000miles and hope for the best when I go to take it in for required maintenance. But I'll tell you, compared to my stage 2 m240i, the car doesn't seem much quicker right now, but I haven't compared apples to apples yet. I'll provide an update once I'm able to properly open her up. Still the best car I've driven and it feels wonderful.

Here is a dyno graph example of a stage2 tuned M240i. As the graph indicates, a stage 2 B58 has tons of torque. In order to get that kind of head snap you'll likely need to tune your CS.
