I was watching a review for the F150 lightning (Redline Reviews - Reviewer has a MME GT) and per the reviewer Ford told them that the F150 does not have the 5 seconds full power limit because it contains a battery from a different supplier that doesn't require it? Anyone else heard anything like this?

wouldn't surprise me... everyone has their own warranties, concerns, etc.

I guess I figured it was more tied to the capacitor than the battery... but who knows.

Yeah I think so, battery manufacturer could be the reason. I have a Chinese version MME GT that contains a battery from BYD. Never heard anyone complain about the 5 sec limit here...There is no unbriddle extend mode in the Chinese version GT neither.

Can you take a photo of your IPC when driving? The driver screen? Do you still have the power and regen bar?

I always thought it was a mix of cooling and the battery. If the 5-second limit is due to the battery supplier and not something that could be changed via OTA down the road, we will be seeing a ton of 1st gen GTPE on the market once they release the Gen 2 that doesn't have this limit.

I fail to understand why the other trims don’t have a 5 second limit then, if it is the battery.

There's gotta be some component in the HV system that can't handle the current load at full power and the 5 Seconds Rule is conservative to prevent damage.

The best description of the theory I've heard is that there's a meter that measures how much current has passed thru the component in a given time window and once exceeded, it restricts the power. That's why GTs have limited power above 80mph because the current load is already high.

I hope we'll see an OTA improvement but kind of doubt it.

Doesn't the GT also have the 5 second limit?
Yes, but the Premium, CA Route 1 and Select do NOT have any kind of 5 second limit at all. Sure, they're slower off the line, but I believe people have posted times of a Premium vs GT/GT PE and the Premium pulls away once the GT throttles.

Would be nice for Ford to finally just shed light on it! Like I've been saying all along, if they at least said WHY it would still suck, but at least we'd have an understanding.

I don't know if that is why, if I baby my GT PE up to 70 and try and gently push up to 100, I'll still probably lose to a Premium as I'll still have gray bars limiting my power, even gently accelerating up to 70.

That sucks! Why call it a GT? My 5.0 GTs, all 6 of them, never have the fuel injection cut out after 5 seconds! Please more time Ford! Or change the trim to MachE Touring as theirs nothing grand about 300 seconds!

The GT draws substantially more current than the other models. not too far from 1000A foot on the floor. You'd think that much current would heat something up.

I saw the same video you are referring to from Sofyan (Redline)....
I am thinking bc this first manufacturer is new to Ford and not enough testing prior to releasing the MME, they want to be cautious as much as possible.

I thought I would hate the 5 sec limiter as well but it has not been the case with my driving it.....

Not to say that I don't want it taken away......Not a deal-breaker with me

The 2016 S550 Shelby GT350 has known overheating problems that causes it to go into limp mode. There's a class action trial next month over it. I know it's not a 5.0 coyote but my point is that the fossil GTs aren't immune to getting nerfed.
