Anybody have a solution to get rid of the max 5sec power cut off

Well of course you can make it slower by running in extreme conditions, but what would be the point of that?

Nothing, just a little salty that we haven't been able to try full power yet.

I’m curious, if you try unbridled extend in the cold, are the gray bars still there?

Not sure, haven't tried extend mode yet. Will have to give it a shot!

Class action lawsuit. I would not have bought the GTPE if the 5 second power off was disclosed. Any lawyers on our forum please comment. Remember in disclosure all emails must be produced and the smoking gun would be "keep our power down from any possible loss in sales."

I support this idea

Here in "downstate" NY, temps have been in the teens and 20's- The times I know I'm going out I've been using the pre-conditioning in my unheated garage. Happy to find no or just 1 bar when I go out, with plenty of power on tap... and a warm cabin too. Would recommend the pre-conditioning to any who haven't tried it. Can do it from your FordPass App or in the car.

I thought I heard in one of the munro battery pack disassembly videos that there is a potential thermal bottleneck in the design? Instead of all aluminum they went with plastic and an aluminum strip. I'm sure Ford is just playing it conservative and will increase or reconfigure the limitations for the GTs once they gets some more data- but I can understand the disappointment now for sure.

“Potential thermal bottleneck,” yes. But it’s all speculation at this point as to whether or not it’s really an issue.

Looking at the temp logs on multiple back to back 0-100 mph runs, heat really doesn’t seem to build up…… anywhere. Even the temporary inverter temp spike drops immediately and during the full throttle run.

You can precondition cabin plugged in using the seats and steering wheel as heat source. Heater not recommended plugged in. 15 minutes and cabin is toasty at 20 deg.

I wonder how that temp graph compares to a Tesla model Y performance making those same runs which does not limit power. Would be interesting.

Yeah I’d like to see that too. To see what temps are “normal.”

My hunch is that Ford wants to play it safe with the 5 seconds max power. Keep in mind, the MachE was Ford's very first EV... as the engineers get more comfortable with the power source, I think you'll see the GT improve a lot in this regard.

Most people don't realize how dangerous 480V power is. You make a mistake with 480, you risk turning the car into a 20,000 F fireball. The absolute last thing Ford wants for the brand is a family getting incinerated because dad wanted to show off and push the GT too hard around a curve.

Also, the vast majority of users (myself included) don't care about more than 5s of power. I will be driving this car at 0-40 in the city, and 55-80 on the highway. Under no circumstances will I take this car over 90. The MachE premium performs well at these speeds so while top gear performance might be a moral victory, the vast majority of its customers don't really care about it.

This old wives tale has been repeated here many times.

Show me an electric car that turned into a fireball from full throttle runs.

Any electric car ever would suffice.

This picture is the result of a Chevy Bolt battery fire in a parked garage. You want to argue that the risk of an arc flash fire does not go up when the power draw from the motor is at full load? I work around 480V on a daily basis and every electrician I know would disagree with that statement.

If anything there is probably more safety engineering around what happens to the car while the motor is under full load than while it's in a parked state... so that could be why the fires seemed to happen more in parked cars.

I have yet to see direct evidence of an EV fire started by motor overload. The insulation on windings would melt first, short, and breakers would cut power even if sensors and software didn't. fire contained in the motor case would be unlikely to start the entire car on fire. I've seen old-school inverters without sensors blow capacitors and 'let the smoke out'.... but not start massive fires since there really don't have much fuel to burn.

most of the battery fires I've read thru were started by failed CHARGERS and BMS that failed to terminate charge, batteries went thermal with voltage runaway, vented and started battery fires which are hard to put out. Lithium ion batteries are more volatile than LiFePO4, and there are more connection point with smaller formats making them harder to balance at end of charge.

I agree with you there. What I'm saying is that this is likely due to extra safety measures placed around the motor's current draw which in the MachE's case includes the 5s limit of max power draw.
