I didn't pay much attention to this thread initially as I thought the OP just was experiencing bad launch conditions and we would see people posting consistent runs well under 4. My m340i xDrive is no joke off the line and it definitely pulls hard consistently. Having just placed my 550 order I really hope I'm not taking a step back in quickness. It's just surprising that BMWs claim of 0-60 in 3.6 is so far off. C&D was able to get a 2018 model to 60 in 3.8. With a bump of 68hp and 73 lb/ft of torque over the car they tested wouldn't you think the average launch of the new car would consistently be well under 4? Matt Watson of car wow got to 60 in 3.8 in his most recent 550 test and the EU cars have 530 hp.

I just wonder if BMW did something with the 550s transmission. Did they not want it neck snapping fast for the 550 buyer? Something just doesn't add up.

I've had insane launches, but the majority are kind of :meh: 1st gear has a serious torque limiter and the X-drive is designed for stability not fun on this model.

I just drive with traction off, Sport Ind setup how I like and it hauls ass on command now. I've eliminated nearly all of the lag/no power

Hello fine sir. Members of the forum would like to inquire as to whether or not you are in possession of a Dragy.

Ha No I am not, but I have repeatedly seen sub 4. C&D recorded a 3.8 for a RWD 2020 m340i.

I was peeking into the F90 forum, and noticed a post about a limit the number of times you can use Launch Control...I am assuming the G30 has this limit. Just wanted to give you an FYI:

Limit on LC? https://f90.bimmerpost.com/forums/sh....php?t=1798332

Has anyone measured the 0 to 60 speed for a 540 xDrive? If it’s within half a second of the 550 it’s probably not worth the extra fuel consumption, at least for me.

Sorry for taking so long to respond. When they gave the vehicle back to me, they told me there was some kind of stored error of "Pressure Sensor" i have no idea what sensor they are talking about since they did not specify.
Car is back at the dealership right now for same slow Launch and that the iDrive is crashing like crazy. On the way from work (30 min drive) my iDrive crashed 8 times!..

I was so pissed with BMW i actually called BMW of NA, Spoke with some cool guy, i explained to him that i literally bought the car for the advertised numbers, and he said he is surprised him self, he said usually BMW outperforms those reported numbers, he told me to give the dealership another chance to try to find out why its doing what it is doing and to fix the infotainment, if nothing will come out it he asked me to call him back. I have no idea when my car will be ready from the dealer, but I hope they will accomplish something.
besides that i am completely out of ideas at this point...

Coming from 392 Scat myself. You honestly need to get used to Turbo car vs. NA power delivery.
I have the 2020 M550i stg1 bench tune and it kills Hellcats, trackhawk, and took down twin turbod 392 with built motor from dig and roll making 630whp.
I should make low 600s whp.
My Draggy runs were 2.9-3.1 with best 10.8 @129 car rolls out.
I wasn't going to but I might tune on e30mix next. Because I don't feel like dealing with downpipe. But e30 + downpipe and stg2 dyno tune should make 700whp with 720+wtq
But, I dont know how long the engine will handle it... I don't feel like finding out lol
See below for my 0-60+ run



If you think 392 can touch that launch lol.

I wanted to go the RK-Tunes way my self in the future, 2021 Models currently Have locked ECU.
Also very impressive numbers you got.
But back to my issue, Your 2020 In stock will destroy my 2021 in stock in 0 to 60 time. Ive compared it already with other peoples times.

Here is another update, Today i got a call that my car is fixed and that i can come to pick it up.
Upon arrival they said that they found no issues with the launch of the vehicle (but said that field engineer will be in next week and i can show him the car) however they found some codes for the Infotainment system and had reset the whole unit and do some recoding and stuff. They said i should be good moving forward... I took the car from service, and drove around the dealerships lot to look at some vehicles that my wife was interested in, within 3 minutes of driving my Infotainment went black and crashed... I pulled up to the service and it crashed again... ( this is twice in 5 minutes) They took the car back in to service and now it is going to stay there again...


Any suggestions? I have never had such a bad new car experience...

Does a tune remove the first gear, I’m assuming torque limiter? When not using launch control but just going 100% throttle from a stop, there’s such a delay before it finally gets all the power/torque.

I reached out to the sales manager, he is supposed to get back to me. The dealership gave the car back to me and said to drive it till the part comes in. They ordered a new Head Unit for the car, said it should take 2 weeks to come in from Germany . ��

Ran another few times late at night (empty roads and cooler air) but after driving highway speed for over 35 min to get the tires warm.

Couldn't get the car to display the flag for LC. But tried running some with dsc off and all sport plus as some folks on the FB group thought that might help.

More underwhelming numbers.

At this point, I'm going to wait for a bit more warm weather to see if that helps at all.

Also will eventually get around to going in for a service center check on the car, but she drives well in normal driving. Good response and pickup. Just a bit of a dog in a launch from 0.

Did you checked the tyres?
Do you have summer performance or all season?
The last ones are a mix of s*it performance either in winter or hot summer, without the proper grip when you need it.

I have all season run flats, but I've spoken with folks with stock 2020's on AS run flats and they did 3.65-3.75 runs

Its basically a big "FU" from 2021 Models. You got same numbers as i got. I tried gazillion things with the car. I tried changing the "Tire" Settings, Warmer weather, Colder Weather. Don't Matter. I don't think tires matter at all for the launch since i have 0 Wheel-spin. Its simple, Car is cutting power substantially off the launch. And you are absolutely right about 2020 Models doing better times. Whats even better is that m340i stock will murder m550 off the launch for the 2021 models

Does anyone have the "DHP" Package in the M550? may be that package gives you the advertised 0 to 60 times?...

I have DHP. Same issue with weak launches. The car noticeably cuts power at launch.

Well in that case, looks like a Tune is the only option once its released..

In the meantime I'm going back to a dealership in 2 weeks once the new Head Unit arrives from Germany. By the way, i got a call from someone who "teaches" BMW features and what not, and he said "You're probably getting wheel spin that's why your launches are slower than advertised", i told him i don't hear or see it on the dash, he suggested different fuel and stuff but i've tried it all. Oh he also tried to tell me that "Head-unit crashes are normal"

Hmm maybe it's something that could be addressed with a technical update of some sort if it's really just a computer setting messing up the low gears. Would probably need more evidence and complaints to see something happen. I am at just 590 miles but I'll give it a go in another 600 once I'm at 1200.

I have DHP and AS tires .. also have a Dragy. I'll throw down some info too when I'm there.

Without turning this into a full-on review, I will say that overall the car is great but am disappointed with more things than I expected. It's my first German car and my first turbo'd car. I've had only naturally aspirated or supercharged vehicles, so throttle response took some getting used to.

Most recently I've driven a Jeep Trackhawk (AWD, supercharged, auto, 700hp) and a Corvette C4 ZR-1 (RWD, naturally aspirated DOHC V8, manual, 527hp). By comparison, the M550 seems to have double-lag at launch: the throttle tip-in or gas pedal sensor delay + turbo lag, but once the car gets going its on-par with the Trackhawk, and at any speed above 50MPH it's dangerous fast because of how smoothly and quietly it builds up speed.

I think all my problems with it (aside from a million buttons that seem to do the same thing) are related to driving style. I've tried customizing Sport Ind. mode but I can't 'fix' this characteristic of the car.

The best thing about the M550 is it combines alot of what I liked about all my previous cars into 1 great tourer.
