F90 M5 vs F90 M5
Hi everyone,
Firstly I hope this thread is in the right section. Secondly I'm curious to know if there is any performance variance from a stock M5 F90 to another stock M5 F90? What causes it? Does newer MY models get faster? Regards |

The driver and their skill level.
Aside from that, yes every car will be different and some are faster than others, although the difference will likely be negligible. There can be a lot of different factors, but mostly it's just due to variance in production. BMW does not intentionally make the newer model year any faster than the previous as long as they are the same model and package. A standard M5 will not be as fast as a M5 Comp, but same to same the difference will likely only be noticed when you factor in the drivers ability in the car. |

There will be performance variances. It is impossible for BMW or any manufacturers to make every M5 having the exact same horsepower and drivetrain loss.

Two autobild test on the M6 coupe. One test was in 2014 on the 575HP M6 CP it ran 0-300km in the 30 second range while in 2016 the 600HP M6 CP ran 35 seconds plus. Sure it wasn't tested on the same day but 5 seconds differences? And the 600HP was actually the slower one? I do not believe differences are negligible, there bound to be some cars that are faster or slower. |

I have had a few Monday cars and street bikes and a couple not so. I also believe that a lot has to do with how guys break in the toys. Not so much in cars but when I was riding street bikes they had very strict break in rules that I'm only recently seeing in cars. The problem is that most people will just sit at 2-4k rps and almost wear grooves and smooth spots in those areas. So once the car/bike is broken in it's a bit limited or struggles to be a smooth at the high RPM's as things tighten up. (Set the rings) I'm all for breaking in my toys the way I plan to drive them. With some common sense of course. I don't race them around per say but I make sure to use all of the power band and RPM's but I shift and don't hold high RPM's either. In a perfect world I want my RPM's going up and down as much as possible during break in with cool down periods in between. Turns out, I have in most cases ended up with the "Monday" bike or car over the years. Could be luck, could be how I break them in. Who knows. Just my two pennies Race cars go out on fresh engines constantly, I have also had a few high end sand rails and other custom motors built and they have never told to me take it easy on break in. Maybe I'm wrong which is why I'm still somewhat careful. But, why is it that street bikes have always had break in rules and now faster cars? Why not the 330i? Conspiracy theorist would suggest that it's because they don't want us to kill ourselves in the first week and it gives us time to slowly get used to the car. Which is actually smart!

You may be right about that. Breaking in is more for the driver, not the car? I'm in the racing business and we can put a fresh engine on the dyno with no warm up time except for the oil and it will produce its best numbers right then and there. Modern precision manufacturing and finishing processes I guess.

I broke my car in kinda hard. I was very easy for about 150 miles not revving above 5k.
After that I drove it fairly hard from time to time. Almost just like normal. I even did a couple 1/4 mile runs for baseline numbers. My goal was to keep the RPMs moving up and down. Obviously there is times where it's at one RPM on the freeway for some time but I tried to get on it now and then. Just don't hold a high rpm. Let it wind out and shift
