So i scheduled a service visit to BMW, and asked them to do a "break in service" and explained to them that it feels slow on the Launch Control first gear. They took it well, will be taking it in for service next week. Lets hope something changes after the service. Because the advertised performance numbers were the reason i chose this car. Fingers crossed!
Fyi, a friend of mine has an M850i and he does 3.5-3.6 with Launch Control stock. |

Still slower than officials numbers. The M550i should according to Bmw go from 0-60mph in 3.6 seconds and from 0-100km/h (62mph) in 3.8 seconds.
I was expecting numbers like the friends M850i is doing considering the that official acceleration times from Bmw mostly are conservative. |

Going to take mine into the service shop for that smell and these meh performance numbers in a bit. Would love to get this sorted before my new exhaust comes at the end of March... I still want to try a dragy run or two with warmed up tires on a dry piece of road and see if that hets me the 3.4-3.8 I'm hoping for instead of the 4.0-4.2 I've done on wet roads and cold tires. |

I think that it does actually do 0-60 in 3.6 seconds, but people are getting 3.8 because the app or timing equipment people use, register 60 mph as 57 mph, and so you would have to go around 63 mph for it to register as 60 mph, therefore showing the wrong numbers on the app/timing gear.

I just took my 2020 M550i with 1000miles and a full tank and did 2 very and quick brake boost launches with dragy. There is a slight pause once I release the brake and I was in sports+ and traction off.
I’m in Australia and numbers are (not sure how to add a screenshot). 21c DA 532m 3.37% slope 0-100 4.22s 0-50 1.78s - 30mph is 48kmh 0-80 3.08s - equivalent to 50mph I’m not using LC but that’s a fair bit off the claimed 3.8 but I’m guessing LC, less slope should do better. So those numbers are better than the OP with time lost at launch and the increasing slope. My previous run had it at 4.4% on the same stretch as it’s not a consistent slope. I’d agree the OP is losing time at the launch. The time between my 30mph and 50mph is 1.3secs which is similar. I wonder if cold weather means it’s spinning and you can’t feel it?

Disappointed..
Update: i hate when things like these happen... i called my local BMW service center 2 weeks ago, no one ever called me back so i was forced to go there in person. When I went in person to BMW service i asked the service advisor, does the 2021 M550 have a break in service? They answered yes and scheduled me to do it.
Today i show up to that scheduled service, and the new service advisor tells me there is no such thing for M550s and it only applies to to M5. And basically gave me the look of wtf am i doing here? (I wanted to scream WTF!!!) I barely held myself from flipping out.. so i explained to them that the car is very slow off the launch with the first gear and that I want an oil change on top of that. I told them that i bought the car based on the advertised 0 to 60 time, which is no where close to what i was able to acheive. They took the car in, but i have a strong feeling nothing will change... I don't even know what to do at this point, i feel cheated i literally got sold based on those numbers... BTW, i did do more 0 to 60s with Launch Control (before i took the car in for service) since i am above the 1200miles. I had quarter of a tank gas, car was warmed up, Launch Control activated (checkered flag) and best 0 to 60 was 4.1s!!!! |

Did they say anything about the lack of performance from 0-60? |

I have older M550 but thought I’d add that in the iDrive system there is an option to select tires, when I went in there it was set incorrectly. (Most likely because I requested dealer not to do anything except activate the car as North American). It took me half a year to notice it, when I changed it from the wrong tires which were something like 18” 4 season to 19” all summer I think it effected my off the line power… hard to say for certain. Could be a placebo effect, But maybe it’s worth a check if anything is limiting you.
Also, you may need summer tires and warmer weather to get the grip necessary for your cars best times. The current cold weather and all season tires are going to loose some degree of traction. Good luck, and try to enjoy the car, it is amazing |

My 2021 is an absolute dog coming out of corners. It's like 200HP. I have to drive with traction off (quick click of the button) in order to get this thing to be exciting.
It's fast AF, but it's fast AF when it wants to be.
