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.I don't know how software is going fix the issue if the root cause is a limitation in the cooling system.
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 .Cool. I'll give it a listen tomorrow when I get a lull in my work day.
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.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
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.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..
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.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.
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 EVsEverybody in the GT engineering group knows/knew exactly what it would trap in the 1/4 mile.

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.
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.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.
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.I should have been more specific, Porsche and Tesla are the only ones setting full 12.9 mile EV laps and bragging right now.

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