2024 Mach E GT performance upgrade OTA

[Mach1E]

I have noticed the pull, from 0 to 60+. It's not night and day, but it's there.

Wondering if made any difference above 60 mph (60-100 for example).

It’s been 3 years and we still have ZERO Dyno numbers for a Mach E GT.

Would be helpful to see a Dyno before and after upgrade to know what’s really happening. Or some acceleration comparisons and we can extrapolate.

However, based on the numbers, we KNOW this-

1 speed transmission.
480h peak either way. 600 vs 700 peak tq.

Since hp= tq x rpm/5252, we know that peak tq is well under 5252 rpm (if you had 700 tq at that rpm, you would have 700 hp).

Based on how my car accelerates, peak torque comes in around 30 mph (around 3000 rpm).

I would expect the 700 peak tq to feel similarly.

We also know that power starts getting pulled on a 2021-2023 at 72mph and above.

We don’t know if the same is true for a 2024 GT without the perf upgrade.

If not, the performance upgrade is really just going to be felt at low speeds (0-40mph or so).

Either way, I would totally pay for this given the option.

60+ seems quicker. Doesn't tank out like others GTs I’ve driven (22s, 23s, 24). I did drive it for a couple weeks without. Sorry I don’t have better data, but it FEELS faster.

One way to know for sure is if someone takes a 2024 GT to the drag strip without the performance upgrade.

If it still traps 103 mph, we know the trickery they’re doing here.

Hi All, this is my first post to the forum. On July 6th we took delivery of a Star White Metallic Tri-coat 2024 MME GT including the performance upgrade for $995. The upgrade hasn't happened yet, but, the dealer says that it will "... in a month or so...". They indicated I will need bring the car back into the dealership in order for them to connect it to their computer for the upgrade. I've asked again for an update, and I will post about this when I know more...

I posted on July 24th that we took delivery of our MME GT on July 6th, and that we had paid for the Performance upgrade at that time. It turns out that we did have to return to the dealer to do the upgrade, but only to clear up the money issue. We did that, and I activated the upgrade there. By the time we returned to our car, the screen read "Performance Upgrade Enabled". So, although I don't know how long it took, it was less than 5 minutes.

The car was fast before, but afterwards, it was mind blowing! It is now scary fast. I took our sales guy for a ride, or I should say, I let him drive me (he's a great driver, and has his own MME). He showed me what the car can do on the freeway, and on curvy roads. We both had huge smiles during and after the ride. Great fun, and soooo fast!!!

My results of my '23 GT/PE vs my '24 GT W/Performance Upgrade.

Side by side the '24 pulls about a length and a half to two lengths to 60mph, then60-75ish it's a slower pull, then past 75 it rips (when the '23 power limits).

60-115ish is night and day vs the '23, it just pulls.

115+ the '24 still power limits.

Sounds about right.

My guess is that if you did a roll race, from 40 to 75 they would be dead even. Only reason you would pull from those speeds is that the 24 was actually going faster already…… or if they changed more power than the stats suggest.

Would still love to see a side by side video of a drag race and roll races from different speeds.

@blueovaltech thanks for posting that data. Now I can analyze it.

If you do the math, the new 2024 is significantly more powerful in the second half of the drag race (above 90 MPH):

• 2024 GT Performance Upgrade:
  • Average acceleration past 660 feet: 7.6  ft/s^2 (5.2 MPH/sec)
  • Estimated horsepower past 660 feet: 330 HP*
• 2023 GTPE:
  • Average acceleration past 660 feet: 4.4  ft/s^2 (3.0 MPH/sec)
  • Estimated horsepower past 660 feet: 180 HP*

*FYI the horsepower figure is based on weight (5200 lb) and acceleration only. It does not include drag, which would be an additional 150 HP at 100 MPH.

And if you do even more math, the estimated gap between the two cars would be 110' at the 1/4 mile.

This supports what I felt when I drove the new GT. SIGNIFICANTLY more top end power because the jail bars don't kick in until after the 1/4 mi.

In other words, the 24 is what the 21 SHOULD have been, and what those of us who pre-ordered a GT or GTPE expected. Good job Ford, just three years too late.

Could someone explain to me what it would entail for ford to at least unlock the extra HP the 21-23 cars have without increasing the torque? Would this be/not be possible? What would consequences be? I’d like to really understand this as technically as I can.

21-23 have a different rear motor than 2024+ that performs differently (different torque curves). The extra performance is tied to a robust unified thermal model they developed. Because the hardware on the 21-23 cars is different, the 2024 thermal model won't work. It would take time and money to go back and develop a model for 21-23 cars, so I don't think it's going to happen.

Hp= tq x rpm/5252.

It’s literally a formula.

The reason the 2024 and 2021-2023 have the same PEAK horsepower is that the extra torque in 2024 models all comes well under 5252 rpm (for practical purposes under 45 mph).

Above that they “should” be nearly identical…… but Ford programmed artificial power limiters that kick in above 72 mph, and after a certain amount of time, and at lower charge percentages as well as at certain temperatures among other things.

What would it entail? A simple programming change.

Consequences? We would be faster but there is a chance our cars would be less reliable.

Why haven’t they done it??? At this point probably because they have frankly moved on to other things, despite the fact they promised they would.
