I recall this happening to Kyle Conner of Out Of Spec studios during his i5 test drive in Portugal, but I heard him make the same complaint recently on the Batteries Included podcast in defense of the A6/S6 possibly being a better bet….but it made me wonder if anyone has actually experienced this phenomenon in the wild? I for one have not - I’m not exactly trying to track my car, so maybe that’s when it would show up, but it struck me as an interesting yet unanswered question.

Experiences? Thoughts?

I’m curious too. As I recall there were two issues he brought up that I hoped for a follow up on by him or any other reviewer, but there never has been.

1. Drop in performance after pushing it hard, even though that wasn’t supposed to happen (thermal derating?)
2. Cabin noise at head level (where from? The panaramic roof? I already want to avoid the glass roof, so is the car quieter without it? Dealer lot cars all have the glass roof so there’s no way to test drive it)

I have not noticed it. I was driving for 90 minutes each way today. I mainly drove at about 80mph but took it over 100 a few times.

It’s not speed per se, just prolonged hard accelerating and braking. In the video you could see that the top part of the power band was blocked out as the drivetrain (motors and/or battery presumably) exceeded some sort of temperature threshold. 100% power came back after he drove in more of a normal mode for a short period. I’ve not heard any other review or bimmerpost or other forum member replicate this situation.

Here’s the video - the derating starts at ~55:36

I watched this about a month ago and right after tried to search up info, and then tried to see if there was any way to contact out of spec reviews but came up empty (channel website has no contact info)

I know the Mustang Mach E GT Performance has a 5 second limit, then you are locked out for a short period of time. They fixed it in 2024. It could just be software.

Could be a software problem, but I believe Kyle specifically mentions that BMW engineers said it shouldn’t happen. This is kind of a big deal when reviewing a performance car EV that it really needs a follow up. Pulling available power after only a very short spirited drive kills the sport aspect, and would be hugely disappointing if I bought one and found this out.

I see the out of spec studios contact page does have icons at the bottom for the big 4 social media platforms. I briefly checked the facebook and twitter ones. Facebook appears abandoned but twitter seemed active, didn’t look at the others. I don’t have accounts on these anymore because I didn’t enjoy them, so maybe somebody else can try to make contact with Kyle or Out Of Spec on twitter or instagram and request a follow up about the i5 M60 power derating behavior in some future podcast.[

He’s actually been on bimmerpost over the years, it hasn’t posted since the i5 review dropped last year. Pinging kconner5 on the off chance ;-)

Love that he just posted a video where a guy he met at a charger near the Nurburgring agreed to let him post a hot lap of the ring in his EV6 GT just because. Hilarious.

I don’t think that worked.

Hail Mary obv ;-)

[Blue Sky]

So…. Is somebody going to post on one of Out of Spec’s social media pages?

[RichardInCA]

I think the lack of response or of anyone reporting this phenomenon is probably telling. My guess is that this is not a real-world issue.

[Blue Sky]

I’m not so sure. My impression is that this car’s buyers don’t really drive ‘spiritedly’, and don’t rip on canyon backroads, don’t rotate the car with oversteer.

How about the torque lockout except when steering wheel is nearly straightahead as mentioned in this same video at 51:58? You can’t do any drifting if the car manages your inputs. Fine if this is just a setting that needs to be turned off that is there to keep people safe since this is a lot of torque that comes on faster than with an ICE vehicle, but is the car hobbled to prevent eating into M sales?

Kyle also mentions in a Tesla Model 3 Performance review about the i4 also limiting torque based on steering lock (perhaps he confused the i4 and i5 reviews, I dunno).

Yes, I drive a modified F10 M5 in case you were wondering. I’ve been wishing for years that BMW make an M5 EV, but I already knew quite a while ago that they would hang onto ICE for the next one (what we now know as the G90).
