Comment by reviewer notes Ford explains the GTPE delivers full power for about 5 seconds, then ramps it back to limit heating. Long term battery life is the goal.

So...
5 SECONDS of power is what you get, that gets you over 60mph and after that, not so much.

5SOP and then CTJ.

That is, you get "5 Seconds of Power" and then it "Cools The Jets" by design.

I discovered this today in a reply to a comment from the GT PE review / drag runs:

Low 12’s but the mph is so low. Is the computer pulling or does it 60ft that good? Not hating, it looks like my next daily driver and I’ll skip the drags with it. Good review!

The way Ford explained it, it gives full power for about 5 seconds then it ramps back the battery power to limit heating. It's done for long-term battery life in order for Ford to guarantee 70-plus percent battery life for 8 years. My guess is that as the technology improves, so will power.

If this is true, it’s software and not hardware as some have feared. This is good. Perhaps there will be a fix in software, perhaps not.

This fits nicely logically with the existence of Unbridled Extend where the whole point is to drop performance a little bit but be able to do it much longer.

??‍♂ Well, they may want to consider ramping the power down gradually enough that the cheaper, less performance oriented 4X doesn’t have a higher trap speed in the 1/4 mile. It’s an embarrassment and can’t be allowed to go unfixed. Perhaps that’s the power “optimization” that @OutofSpecKyle mentioned in his review.

Edit: and to be clear, I think most of us understood that throttling was occurring based on the data, but, 5 seconds at 100% and then dialing it back is just sad.

They basically, purposely made it the modern day version of a ‘92-93 GMC Syclone or Typhoon. Killer 0-60 and 1/4 ETs and low trap speeds.

A lot of EVs use a timed over boost of power, however European legislation doesn't allow you to market using just the larger over boost number you have to use both, as the European marketing for the GT has no mention of over boost power I guess we now have to add this to the long list of Fords marketing shame.

Now of course motors only need to make the peak power at a certain revs to be legally accurate, so all this 5 seconds of power talk basically says at Ford we cobbled together this EV and have so little faith in our battery pack engineering and testing that we have neutered everything because warranty.

As the battery pack has an 8 year 100000 mile warranty, does that mean once I reach one and it becomes out of warranty will I be presented with a you have now unlocked full power achievement on my center screen, brings new meaning to my commute being the daily grind.

It is also pretty much exactly what I guessed at in the original thread on this topic, like 6 weeks ago or more. Pats self on back.. Some people said I was crazy ;)
You and me both.

Doesn’t mean you’re not crazy, just that you’re right. Take it from a dog most of the other dogs think is crazy because Poodles can spell. ?

I though it was also due to the fact that under full power you might start over heating the motor and inverterter. That was also was explain on Out of Spec that part of is the motors and inverters can start over heating pretty quickly under full power so it backs it off to keep them from over heating as fast.
I can buy them also doing it keep the battery from spiking in local temps way to fast as well and lets it balance it out.

Asking as a non-drag racer, why does anyone care about the trap speed? The winner of the race is the one that crosses the finish line first (ET). ? ?

Trap speed is an indicator for how quick your car is from a “roll”… ie passing power on the highway or roll race. So if you take a GT and a Honda Accord at 70 and punch it at the same time they will have almost the same 70-100 times… so in other words you have the passing power of a Honda Accord. That’s why the Model Y is better at highway passing speeds, higher trap (112-115). Also 10+ MPH difference is about a 150 hp or so difference, so Ford is realllllly limiting power after 5 sec.

But I don't think your example is actually true. The analysis indicates the reason the trap speed is lower than expected is because of the 5 second power limitation. Assuming you didn't just accelerate from 0 to 70 in your highway scenario, the GT would have "full" power on tap and would blow the doors off the Honda.
