Cloud 9 i think said his was in transport mode.....

It was on Saturday before the dealer even had a chance to prep it. I just went in to take care of the paperwork and the sales manager told me to take it for a spin. It still had the paint protection on it and I noted that in my post I did update it today with my impressions after I was able to "officially" pick it up. I was surprised it wasn't more limited in transport mode.

**maybe you're asking if the OP's car was still in transport mode?**

Why do you keep bringing up Mexico are you racist or something?

It's a running joke. If you ever watch YouTube, you'll see people going way too fast with disclaimers that they're in Mexico.

Mexico is incredibly diverse and depending on where you are looks an awful lot like North Carolina, Salt Lake City, or Wisconsin.

This is where we find out Transport mode has a 100mph limiter. ???? Also known as “Accord is King” mode.

I've been doing some digging and found this PDF from a company that does electrification for vehicles.

Page 7 references this company's IM-225 that has peak power roughly equivalent to the iDM Module (slightly more) and marginally more torque and a max RPM of 12k.

@phidauex do you think this could be a decent approximation of power/torque curves for the iDM modules? I'm reaching the limits of my engineering background (read: None) to really interpret this stuff with any conviction.

¡Viva México, hermanos! I learned a lot about power electronics from a good man from Puebla, so here are some more thoughts on power and voltage.

I think that the graphs you show are probably pretty close in scale and shape to the motors in the MachE. The absolute values are certainly off some, but you are looking at a graph for the same design of motor from the same manufacturer in a similar iDM, so the "shape" is probably representative.

From this, we can tell that power is roughly proportional to voltage (over the constant torque range), and that power at 12kRPM is about 65% of the peak power. Pushing out a bit further to 13.8k RPM you're probably looking at about 55% of peak power.

This makes the voltage point well - I took some measurements on my Premium AWD ER (more detail here: https://www.macheforum.com/site/threads/driving-dynamics-and-charging-data-files.8473/page-2) and it looks like the resting battery voltage is about 387V at 100% SOC, and about 360V at 72% SOC. I also measured an internal resistance of 35.5 mOhms, which you can use to calculate voltage drop at different powers.

So by charging to 100% you'd have about 8% more power to work with, compared to 72%, or about 36hp peak. That isn't enough to explain the trap speed, but it would certainly help. Voltage drop under sustained high power will bleed more off too. At full power the car should be pulling close to 1000A, which would see a voltage drop of about 35 volts, or almost 10%.

I'm looking forward to seeing some more runs with voltage and current data recorded, it should give us a better idea of when things are limiting and why.

This is all new and fascinating to me. As someone who has only owned extremely boring cars before my MME, I've never heard of this service before.

So you can take your car to a race track and they'll time it for you? What's this service called?

It is called drag racing. Any drag race track (just google your area) will provide a time slip for you after each run. If it is your first time, look for days labeled "test and tune" or similar which are open to everyone vs. race days which are competitions for those signed up and qualified for them. Note: given the speed of the Mach-e, you will likely be asked to wear a helmet for your run (this may vary state to state I am not sure). Some tracks will rent them or a Motorcycle helmet will work, as long as it is new enough.

Thanks! I thought drag racing tracks were only for serious competitions. Didn't know you could just walk in off the street and do it.

I can't believe Ford hasn't responded to this at all to either correct it (if it is wrong) or at least try to spin it for PR.

Seriously, all they need to do is come out with a little correction story that says "we did 1/4 mile testing and were well above 100mph on each run."

But no. Instead it's complete silence and no professional reviews.

Or - If this is really the expected performance: "We tuned the Mustang Mach-e GT to provide maximum performance the driving enjoyment on the road and up to any legal speed limit in the US"

I think the major take away here is that the AWD ER did it at something like 104mph (based on what others have said), so I seriously doubt they setup the GT to do a lower trap speed than an AWD. So something is up one way or another. But if the AWD is hitting a higher speed, then that gives me comfort that the GT will be faster once this is all figured out.

Two or three weeks ago I asked Mike Levine outright on Twitter when we could expect reviews. He replied (I love senior managers that engage with fans on Twitter) with "a little while longer". I paid attention to his account over the few days afterwards and they were in the desert doing a Raptor event.

Just yesterday all the automotive sites dropped their articles on that event and the new Raptor.

It's unlikely that Ford would also drop Mach-E news (despite this thread) and distract from the message of the week- The Raptor. My guess is we are still ~2-3 weeks out, because Automotive Journos aren't puppets for Ford, and likely can't run headline stories on Ford products in back to back weeks for obvious reasons.

There are two other ways to explain that though without something being off.

1) The GT was regeared to provide more low end acceleration (better 0-60) at the cost of top end speed. It wouldn't take much of a change.

2) the front motor on the AWD trims has a higher limit and lower torque fall off so that it can pull a little harder on the top end.

It is also odd that it will soon be 2 weeks since first delivery and only 1 has shown some data on the 0-60 and 1/4 mile? Ok, I think there was one other that gave a 0-60 or so but for a group of owners that obviously is buying the GTPE for performance, just seems weird there isn't more data and videos coming out let alone professional reviews.

@0t60-3.5 thanks for posting, we do appreciate it. Regardless of the bickering about the data, I am sure you are loving that car. I have a Premium that I will be trading for the GTPE in a few months and I am loving it.
