Our 23 GT was quick to 80mph but then tapered power off somewhat. Our 5.0 Mustang GT would usually catch it and pass by about the same time and would out run it there to higher speeds. At least as high as I wanted to go. Our 2025 Premium, AWD extended range is a nice compromise and got us a range boost and is a nicer ride, less harsh than the MME GT (non magnaride)
The 2025s in general have nicer rides than the prior model cars, excluding the older Magneride cars, which have a pretty nice ride. 😁🐩

2024 Mach E GT w/performance upgrade

The PU doesn't add much to the top end. It's mostly on the low end, from zero to about 35. Yes, it's a little punchier above that, but once in jail bar territory (72+) there's virtually no difference. 🤔🐩
There is a huge difference in top end with the performance upgrade. 114mph trap speed in the 1/4 mile vs 107mph for a non pu 24-25 GT. Or 102mph at best for a 21-23 GT or GTPE. No jail bars on my GT through the entire 1/4 mile run.

The trap speed is mostly due to the 2024+ car being able to hit 60 more quickly with the PU and sticky tires. A rolling race from 70+ would be pretty even. With or without the PU the car has the same horsepower. It just has more peak torque and it's all down low. 🤔🐩

It pulls through the entire 1/4 mile. It's not mostly from hitting 60 faster. 3.3 vs 3.7 seconds to 60mph is from the extra torque, yes. Hitting 60mph quicker by .4 doesn't make up 7mph in the 1/4. The tires also have nothing to do with trap speed. That's about 60ft times and ET. The torque curve is much wider, not low end only. There is a difference at 70 plus. That's where you look at 1/8 mile and 1/4 mile trap speeds and the PU gap between the non pu is evident as it keeps pulling away. 87 to 107 for non pu and 91 to 114 for gt PU. That's a large difference up top. Been racing a long time lol

Question. Does the performance upgrade have any effect on range?

Yup, so have I. In order for a 700 lbs/ft powerplant to make 480 HP, the torque curve needs to drop off prior to 4K RPM since HP = Torque/5252. See the simulation at https://www.automobile-catalog.com/...rd_mustang_mach-e_gt_performance_upgrade.html for an illustration of how fast the torque curve needs to fall off in order to make power the way Ford says the car does. 🤔🐩

I drove a premium AWD ER for 2.5 years and now have a GT w/ PU and summer tires for about a year. The two cars only have the name in common. Acceleration on the highway is vastly different between the two at any speed. I recall kicking it hard from Chicago to Milwaukee with a full vehicle and it performed like a champ. I could have never done the speeds / passes that I did with a premium.

OP owes it to himself to try again. I’d recommend the Pirellis. Don’t wast your time with shitty A/S.

Hmm. The extra 100 lb ft of torque must be FM then. 🙃
There’s an app I use to keep track of my wallet and keys. For some reason it also provides stats about my driving. I average 14 rapid accelerations per week (balls to the wall). During those times, my efficiency goes to shit. But not during other times when I’m driving like a responsible adult. The torque is there, but I’m not using it most of the time. I don’t think there’s much difference between my GT and my premium from an efficiency perspective.

Ok, I just got a 2023 Mach-E Premium AWD extended range rental on vacation and my 2025 GT without PU is absolutely faster at all speeds.

And I only charge my car to 60% so it’s probably not even getting the full power. So not sure what was going on with the one you test drove.

It would be nice to see a real dyno reading from both units and compare. Fords crank hp/tq numbers vs at the wheels don't translate to what is actually going on between the 2 GTs. What i can see is that the GT PU pulls above 70mph over the non pu based on real world drag strip data.
This is from a non pu in the picture example below. Under 19mph gain from 1/8 to 1/4. The GT PU traps 23mph from 1/8 to 1/4. That's significant.

Agree with the above, as someone who has raced both models extensively. The top end pull is much stronger. Here's my '24 with the P/U vs the non P/U shown above.

'23 had 13 MPH less trap speed in the 1/4 than this '24, and like 3 less in the 1/8th, the 24 just pulls harder all around.

And here is a good video vs a 5.0L Mustang during Race Week this year, showing even on the back end the GT with P/U has plenty of pull to hold it off:



In regards to the OP's original post, sounds like the classic mistake was made of thinking Unbridled Extended mode was the fastest. It's a huge power hit (mine goes from running 11.8 1/4 mile to 12.9 1/4 mile during testing).

Ford has never been honest about the power these cars are making. I wish we had a Dyno of a 21-23 GT then a 24 with and without the PU.

I bet what we would find is a 21-23 falling flat on its face at higher rpm’s, the 24 without PU not falling on its face and the 24 with PU making more power at all speeds.

Trap speed is an indicator of horsepower and it doesn’t lie.

No chance a 21-23 (103 mph) 24 (107 mph) and 24 PU (114 mph) make the same horsepower.

If it was just an extra tq boost down low like you suggested, the 24 and 24 PU would have the same trap speed.

That’s evident by the 21-23 GT vs a 21-23 premium 4X. Both have the same trap speed but the GT is about a full second faster in the 1/4 mile and all the gains are below 72 mph.

Don't use Unbridle Extend. That's intended for track use to post consistent lap times, but will actually limit peak power.
Turns out I wound up buying the GT I test drove a couple days after trying it and also a Tesla.
I went through the setup screens and made sure Extended Unbridled was off.


Oh yeah, it wasn't even a subtle difference. About the same at stop signs creeping speeds, but 'mid speeds' 60-80km/hr, more pull than the test drive.


Also noticed I can add the performance upgrade via the Ford app. Must be older model GTs, but I thought the upgrade ones had a larger front motor to match the rear. Guess it was so pre-2024?

Will likely do the upgrade after i have a couple weeks with it as-is, so I can appreciate the boost.
