I don't know how software is going fix the issue if the root cause is a limitation in the cooling system.
Discharging (and charging) extremely rapidly creates heat and unless your cooling system has essentially infinite ability to remove heat that means your batteries are going to get hotter which causes battery degradation.

Which means ALL electric vehicles have a limitation in the cooling system. The question is, how much fun do you let people have before you start pulling the plug in order to preserve the battery in order to prevent warranty claims.

The answer to "Is it software" or "is it cooling" is absolutely 100%: It is both. But there's no hard limit in the cooling system that physically completely prevents the GT from trapping 110. What there is is software programming that's limiting power output to prevent battery degradation. Maybe it's because Ford is being overly cautious or maybe it's because the cooling system they engineered is cheap garbage. Even if it's the latter, they could still uncork it and give us our 115 mph trap speeds. It'd just probably cause a shitload of battery warranty claims 3 years from now or whenever.

I could see rapid discharging and recharging being an issue on track with a combination of hammering the brakes into a corner and regen then accelerating out that it could soon heat things up, in theory this is what unbridled extended should be accounting for by slowing things down to prevent it, mind you if they had upgraded the GTPE to use some actual performance brakes then they could have probably disabled the regen all together and just use friction braking only.

For a quick blast down a 1/4 or even just accelerating to from 0-100 mph, it just makes no sense, so either it really does have a piss poor cooling system not fit for purpose or as you say they just so paranoid about warranty claims the fun is quickly dial back or worse case a combination of both :(

Which really does make me wonder what actual performance testing Ford did, typically a Ford with performance expectations I would have expected someone would have at least got some spy shots of it going around nurburgring like most of the other performance fords have, but nothing for the mach-e.

Maybe with all the delays they got to do so little performance testing that they are using owners data to do it for them and make improvement to the performance over time, or the performance objectives that where set are so low nobody at Ford sees it as a problem..

Cool. I'll give it a listen tomorrow when I get a lull in my work day.
Scanned through to the end, not much in the way of details just goes on about unbridled extend, but GT is supposed to have cooling upgrades, if that is the case then current 1/4 mile trap speeds don't match those cooling upgrades :(.

The interesting point with the unbridled extended is lower point at which cooling kicks in so they pre condition in advance, if that is the case then I can't see why the can't just add a sport+ mode that does the same for normal driving, sure it may reduce the range but I don't think someone launching everywhere they go or doing multiple 1/4 mile runs really cares about range they just want maximum beans from the go pedal.

Still looking to compile a bit more data on rolling/no-load pulls, but early results showed 30-50 not affected (as expected), with 50-70 shaving off .5 sec, and it snoballs from there.... Need a few more days of driving it with no rain and should have good data to share...

It continues to make me sick looking at MYP 0-100 times and they're in the range with our 60-100 times 🤔 🤮
Haha. Yep. As I’ve stated before, I get 1.5s 30-50 and 2.0s 50-70 in my ICE machine with a 3000ft DA, so maybe 1.4/1.9 corrected. So, the GT is noticeably quicker 30-50, essentially even 50-70, but, then my 70-100 of 4.0-4.1s is in the Alderaan System when the GT is still blasting it’s way out of Mos Eisley. Or something.

Sickening is an apt descriptor.

Everybody in the GT engineering group knows/knew exactly what it would trap in the 1/4 mile. Because they had Tesla Ys as benchmarks and I guarantee you they were lined up and dragged. Repeatedly.

And nobody but Porsche and Tesla is currently taking EVs to the Ring because the Green Hell is where EVs go to die with the current tech. But, they should be, because that venue is going to result in breakthroughs.

Not quite. The question is how fast can the car dissipate the heat. Yes, there's a limitation and how much cooling is available will somewhat dictate that limit.

It is not just Porsche and Tesla testing there, from a spy shots perspective there are far more interesting things to be taking pictures and videos of so many may well get ignored but other manufactures use it all the time for EVs



Even if ford never tested at the ring I would be good to know how well the GTPE did around Fords Lommel proving ground, but we may have to wait until the euro realese for that.

I should have been more specific, Porsche and Tesla are the only ones setting full 12.9 mile EV laps and bragging right now. Porsche, Audi, VW, Lambo, Bugatti (Now under Rimac) are all VAG so yeah. And yes, Hyundai N has a permanent spot there since Biermann left BMW M and took the reigns of that program.

With EV's for now just being able to get al the way around before thermal issues set in slowing you down is the main bragging right more than the actual time.

Ford have never really been one to chase the lap time records at the Ring, however it still would have been nice to have seen a the odd spy shot of one going through some development paces giving the thermal management a good work out.

So to add some more numbers to the chart, I had time to take a quick detour during the weekend errands runs and grabbed the racebox from the drawer and stuck it to the windshield and quickly capture some numbers, state of charge was 90% so a fresh home charge. (Ignore the time from my quick phone pics of the the race box display as I never bothered to set the correct time zone in all the time I have owned it)

It is pretty hilly where I live and on the only real flat bit of land is a rather poor surface and undulates up and down and as it is right next to farms is always dusty so a perfect drag strip lol.

I only manged to get in a couple of runs as the section I need to use for a relativity flat 1/4 had a fair amount of wheel slip each time so a pitiful 60ft. My results are as expected and matched everyone else as far as ball park time and trap speeds as the power gets cut pretty much halfway through the run.

I also managed to get a few 0-60 attempts in once things had cooled down and full power was available, I disable 1ft roll out as I find it pointless, best result below, again a tiny bit of wheel slip at the start due to dusty road surface and if you subtract 1ft rollout which is typically around .2 then on the 0-60 front I will say the GTPE will match Fords quoted numbers with rollout but you will need a good surface for the front tires to do it on .

I didn't bother setting the racebox up to capture a 0-100 as we know from the 1/4 time the GTPE does not have a good one as power limit kicks in long before.

This has been terrible

the car is at the dealer. Got the call yesterday.
I’m not excited at all about it now and I haven’t even driven the thing.

Well if you decide to cancel let us South Florida Bros know! Maybe we can pick it up without ADM

What dealer are you with?

Go drive it. In everyday situations it’ll rip. Just go drive it. Nothing to lose 🤷🏻‍♂️

It’s midway Ford

it Is really fast out of the hole. But I see what it means after 65-70 mph

and knowing about it I can’t unsee it
