My GT Performance Edition (GTPE) first track launch with videos, timeslip! 0-60 in 4.12s, 1/4 mile in 12.657 @ 100.02 mph

[supared]

Disappointing for a first look. A little screech on launch is fine, but I'd be curious to see what it does with all nannies off and in the right groove (to 60 and 60ft).
Maybe this has been covered, but does the GT even have any track apps? Just wondering if it doesn't have them then what might that suggest about what Ford was really thinking.
Acceleration past the 1/8th just isn't there At All. With bigger motors than the standard models, there definitely is more there. I hope we can crack and tune these things.
As an owner of a supercharged 2016 GT at the limit of the stock motor, I was expecting/needing more.

I really hope that these results aren't reflective of the real maximum potential of this car. I'm not going to pay $70k for a "performance" car that barely traps over 100 mph.

I don't even think there is an embargo in place for journalists, I just don't think Ford has set up a media drive for them to test the vehicle yet. Hopefully, it will be soon, because this thread has me re-evaluating my order.

If it isn't an embargo, then I would have expected those receiving deliveries to be getting requests from the major reviewers to gets hands on and be the first. I haven't seen any indication of that, but maybe folks are keeping it quiet.

Ford's product comms director acknowledged there was an embargo.

It would be even dumber if there wasn't. The first production GTs came off the line over 6 weeks ago it would be absolutely moronic if they hadn't gotten any into the hands of testers at this point.

Well, I haven't seen any teases of a Mach-E GT media drive event that has occurred yet. The Gen 3 Raptor started production at almost the exact same time as the GT. There were a few teasers pics of a media drive at sand dunes somewhere, and now reviews are coming out today. None of that for the Mach-E GT.

Glad to see a Mach E on the track!
Hope to see one at an NMRA event soon!!

In reading this thread, it’s reminding me of a deep dive into the battery pack characteristics I found when first researching the Mach E. IIRC, the Original poster said these runs were at 60% SOC?

Highly technical deep dive, but the important note: “As the SOC and battery voltage drop, the peak current limit will limit motor power as described above. When going to a drag race, start at a full charge - well known advice.”

My guess here is that 60% SOC has a dramatic difference in performance than 85-100%. Unlike a gas car, how full your ”tank” is will impact the results you get out of

That's why I said if. I'm still willing to entertain that there's something wrong with his car or that there's other factors at play but things aren't looking great so far. If it drops off that bad at 72% SoC, whew, what's it gonna be like at 60? 50? 40? I don't know about you but I figure I'll probably be in the 60-75% SoC rather regularly and if it turns the 70k dollar GTPE into something that traps slower than my wife's 27k dollar Accord then it is just not for me.



https://teslamotorsclub.com/tmc/threads/myp-soc-vs-performance-with-dragy.234557/

13.1@100 @ 10% SoC
12.5@107 @ 25% SoC
12.3@110 @ 50% SoC
12.1@113 @ 75% SoC

I think some people don't understand precisely how bad that 99-100 mph trap speed for the GT is but take note that to get a Tesla to run that slow you have to be down to 10% SoC.

This is why I said I'm not sure it's a 12 second car in the other thread.

I’m with you, but I take solace in the 7.99 1/8th mile at 87mph because that’s indicative of a 12.0-12.2 1/4 at 110+ mph.

Come on all of you other 2 GTPE owners, let’s get those Dragys connected and get some more numbers. ??

Sorry I don't have a Dragy, but this is why I questioned whether this was a 12 second car in the 10 mile round trip I had on Saturday. Off the line acceleration is extremely impressive, but like I said it fell off a cliff at rolling highway speeds. I'm hoping to pick it up today, but I'm not sure what the SOC will be since they're moving it between stores to get the tint done.

Any theories on why they might be governing the top end? It doesn't seem consistent with the reports that it's speed limited to 124. All of my past Mustangs pulled hard to the speed limiter, then just flattened acceleration and held at that speed. The limiters were set due to cooling and suspension limitations from what I've read, not the tires. Most of them had tire speed ratings above the factory speed limiter. Again, I am totally unfamiliar with BEVs, so asking a dumb question. Would they limit the top end on the Mach-E due to potential battery cooling issues? With all the stories about battery fires in the Bolt and some Teslas, I'm sure they're being extra cautious.

FYI: I'm posting the Mach E time to the left of my Mustang Ecoboost below.
As you can see the Mach E is very competitive!!

That's not competitive...that's pathetic. It's a 65k+ vehicle with over 600 ft lbs of torque and it would lose and would appear to be driving in reverse at the end of the 1/4.

I'm on the edge of canceling. This is just beyond disappointing.

If you are interested in tenths of seconds difference in acceleration times, battery SOC and thus voltage will matter. 60% to 90% SOC will make about a 30 V difference in battery terminal voltage.

Battery voltage affects the ability of the inverter to push current through the motor windings as the motor speed and motor back emf increase.

The limit for BEVs (those with a single speed gearing) is the rotation speed of the electric motors. They have a much larger range than most ICE engines, but are still limited. Over 100 mph, they are in the 12k to 13k rpm range for the Mach-E. No only is there a rev limit on the motors, but the torque drops off fast with increasing rpms.

I wonder if they geared the GT and/or GT/PE to have more low end torque than the other Mach-e variants at the expense of top end speed.

I wouldn't even bother cancelling, just let the order go through and if you don't like it once you get in it at the dealer then just walk away.

Right now we have one time slip, like most people have said. No professional reviews yet, no one else posting Dragy times, etc.

Makes sense. It felt like grabbing 6th gear in my GT350.......there's almost zero acceleration.

Time for those 2 speed gear box upgrades to come out at your nearest aftermarket Ford shop.

Electric car bench racing. Adorable.

Whatya think it will do with a tune?

First time on a forum?
