Gray Bar Opinions, Please

[The Black Horse]

It seems like you are more performance-oriented than tech. For that reason, I think you will like the GTPE. You are the first person I would recommend this car to.

I have owned the car for two years now, and at this point, I firmly do not recommend it to most. It's just not worth the hassle of a 60-80k car.

That is very unusual. For me the first gray bar appears at around 77% SoCD. To get maximum power you need a full charge, according to Ford and my car's display.

The other morning I had a single grey bar at 82% SoCD. ?‍? That was a little surprising. Heading back from work in the afternoon I noticed 3 bars at about 79%. I wasn’t hammering the car, just driving like it has a bad HVBJB. ??

Here is where you will see the gray bars:

This is my car sitting in my garage tonight and at very warm temperatures. And I have one bar.

I have measured the WOT current draw at 1 bar and it is still over 1,000 Amps, so one bar isn't significant. But it means the car isn't at full power.

I’ll keep an eye out for it. I’m sure there’s been a gray bar now and again, but I’ve never noticed, possibly because that meter is so small, like @buzznwood mentioned.

I have to assume I would have noticed if there were more than a couple bars and I would have surely noticed 12-15, so it’s still not been a problem for me. And by problem, I mean any noticeable power lag or delay.

The car pretty much does everything I ask it to. (Except PaaK or scheduling charging/departure times from FordPass. Those almost never work.)

And, in case it matters, I am a fairly conservative type of driver. I don’t get all that sporty with my GTPE, outside the occasional quick acceleration from a stop. I usually use Engage or sometimes Whisper if it’s raining heavy or there’s snow.

Even when my car has over 50% gray bars, from a stoplight it is quicker than my wife's XT5. So if you drive conservatively, it is easy to see why you would not have noticed the power limitation. Smash the pedal to the floor and you will instantly know.

Which explains why you won’t really notice nor care about the loss of power.

If all you need is a short burst of acceleration, this car should meet and exceed your expectations.

It’s when you push it a little beyond that or even worse, try to push it hard that you come up wanting.

It’s possible (multiple videos showing it) to make this car slower than pretty much ANY normal new car on the road. (Yes, it would get dusted by a minivan) when you push it hard.

And that’s just sad for a performance car that starts out so ridiculously fast.

I can personally confirm that the MME GTPE is “Mustang GT quick”…smoked an ICE GT from 0-70 at 42% SOC (which I consider low).

Now try a roll race with a Honda Accord at that state of charge.

Your comment just proves more how much this car is a “tale of two beasts.”

Insanely fast from a stop (hangs with or beats about anything you’d find at a stoplight). But from a roll or with gray bars? Oof. Grocery getter sedan or worse.

I know this is an older thread but I have a few comments questions on my 23 GT. First, if you worry about acceleration above 80 mph, that's dangerous territory. Anyway the fun is from 0 - 60 and much much safer. I've also experimented from a stop at full acceleration to 80 mph and haven't noticed any increase of gray bars or loss of power and that's definitely over 5 secs. So is the 5 sec limit only at higher speeds? I am more than happy to keep my fun below 80 mph.

Lots of things will limit acceleration in your GT-

Any speed above 72 mph gray bars show up (even just cruising on the highway).

Lower states of charge.

Battery too hot or too cold.

Repeated acceleration.

In your 0-80 run you definitely lose power above 72.

There’s an old video here somewhere where someone took a GT canyon carving. And after a few minutes of fast driving, acceleration literally slowed to a crawl.

At full throttlenit barely moved. Like 1 mph gain per second (10 seconds to go from 70 to 80 mph). It’s kinda ridiculous.

In normal driving and warm temps? You’ll never have that issue.

Thanks for that info, I'm sure you repeated it more than once, so thanks for the summary. I will experiment a bit more just for curiosity. I didn't see any additional bars above 72, but maybe because there was already one or two bars there. They should offer an option you could buy or subscribe to, that would allow limited hits to 10 sec or so, limited based on the parameters they feel are important to prevent damage. 10 sec would be plenty. I'm sure they use quite a large safety factor when coming up with the 5 sec limit.

They did just that!

For the 2024+ GT models. You pay extra and get about 10 seconds of full power plus an extra 100 lb ft of torque.

And it’s significantly faster.
