Darren Palmer: 5-second limit on full power acceleration will be "changed"

[Stang68]

I’m increasingly worried that the ‘21-23 MME GTs will be left behind on charging and performance improvements. We may learn more on Friday when The MME chief engineer Donna Dickson does an interview with the Batteries Included podcast.

Interesting. Hopefull @OutofSpecKyle and Tom ask her about previous model years.

Well, he did change it……. For the 2024 models. And it is available via OTA…….for the 2024 models.

And yeah, we are still waiting for the 2021-2023. I just hope he didn’t mean “for future models only.” I’m guessing we will know in the next few months.

My guess is the improvements will be limited to 2024+ models because of hardware changes in the cars that are necessary to support the improvements. So, if it turns out I am wrong, it will be great news. I doubt it, though.

The only confirmed hardware change is the new rear motor.

Lucky for us that’s completely unrelated to the power limitations.

If there are some more hardware changes, we are all ears though.

The only thing the lack of a new rear motor means for us is we won’t get 700 peak tq.

The fact that peak horsepower is unchanged is actually good news for us.

I don't think any wife should complain about a 2 second increase.

My wife says the shorter the better.
Oh wait, we're talking about the car aren't we?

Without seeing any specs, I feel that the new motor could and should be more efficient. So this means more oomph with less or equal power. This is easier for heat management.

Also, since there are "product differentiation" issues, I dont think it is in ford's interest to give 21-23 models any 24+ model perks, who would buy new ones then. This is the corporate mindset.

With the melting hvjb's and poor heat management overall, what can they do really.

I think you are right on. Back in January I had a conversation with a VP for the manufacturer of the contactors used in the Lightning. I inquired about the Mach-e contactors and was told Ford is already working on the second and third generations of the HVBJB for the Mach-e. Yes. So.....yeah.....I seriously doubt there will be anything for the 21-23 MY's.

But they promised!

They can give us more power for longer.

We don’t know that the 2024 has any different HVBJB anyways.

The 21-23 cars can’t get the range gains of the 24s because of the heating/cooling loop changes and rear motor.

If the HVBJB and battery pack (with the suspected undersized bus bars) are the same, then it’s possible that older ER pack cars could take advantage of the faster charge times to 80% and the GT could see a change to the 5 Second Rule.

 

[rcechinel]

Yeah pretty much…. Maybe 7 seconds...

Won't you take it with a smile? ?

Isn't the inverter packaged with the motor? I wonder if they have made a change there and just are saying that's part of the new motor? That would make sense to me to be able to support more power if the inverter was changed with the motor.

It’s not coming. Donna punted on Tom’s questioning just now.

Their whole "always on" mantra is just complete BS. They're always on spewing nonsense.

 

[Scooby24]

watched the interview she made a comment - hardware changes in powertrain components that allowed to expand areas of increased temperature - moreso in powertrain controls.

Yeah...we are hardware limited.

That's not what I took away from her comments. She said it was modeling and allowing components to reach higher temps but they weren't concerned about prior years because they're going "all in on the 2024".

 

[Hammered]

Well that is certainly a choice of words by the chief engineer of the product. Nothing like leaving your early adopters in the dust.

She kept harping on about "always on" as in they're tracking the cars telemetry very carefully. Made excuses for not having better information in the IPC like charging, saying they have to program multiple modules. That ignores the fact that the IPC can poll any of the other modules over the bus. We don't need special code to pull the same data from the OBD2 port.
