Slight Reduction In Acceleration. Has Anyone Else Experienced This Issue.

[Maineiac12]

These statements with zero data are not helpful or accurate.

I have a 2025 Flash with the 130kWh battery. When I first purchased the truck in May, I did a few instrumented acceleration tests with my RaceBox with only 300 miles on the truck. My best 0 to 60 was 3.83 seconds on a sunny 55°F day at 99% SoC.

A week ago with 70.5% SoC, 3 inches of snow on parts of the truck, 31°F temps, and nearly 11,000 miles on the truck I did another 0 to 60 run in the EXACT same location as the May test. The result? A 0 to 60 run in 3.97 seconds.

So, does the trucks performance deteriorate? Did Ford push an update to reduce the performance of the trucks? In my opinion, no.

If you read my post you’d see that I noticed a change between a 23 and 24 model truck, with the 24 being slower from the factory than the 23.

You own a 25 so any change made for 24 would also be present in your truck. I wouldn’t expect you to see any loss of performance.

The OP has a 23 so his experience lines up with mine, yours does not.

Could possibly be the new bug some people including myself have come across since the last round of updates where users report the same symptom and noticed the system had changed from their normal (Sport mode) to Normal mode.

To the best of my knowledge there is ZERO difference in power output between “normal” and “sport.” You can confirm this by looking at the power display on the left side on the instrument cluster. In both modes the target is the same 100%. The only differences are throttle mapping and a slight increase in motor response time.

Again you are sharing thoughts and feelings but not hard data. Do instrumented tests of 0 to 60 at least 2 or 3 times at > 85% SoC. TC off, truck in sport, and brake boost the launch.

1. The numbers will either disprove or validate your claim.

2. This is also evidence that an attorney can use if you were to bring legal action against Ford.

- conjecture and feelings are not good data

- FORD has no way to 'limit' your speed, or how fast you are off the line, etc. They can't 'degrade' the motors, or 'govern' your speed.

- the POWER Scale graph will show less than 100% as your battery gets to certain low points, or
if the truck is experiencing some type of electrical issue/power issue...

No plans to start a class action, just noting my experiences and letting the op know he’s not alone in his feeling. And based on the posts from many others, he’s not alone.

They absolutely can limit your speed. ICE cars have had speed governors for decades. The throttle response is software controlled in this truck. The power curve could easily be changed by software - that’s how the existing drive modes work.

If this issue were brought to court, I hope Judge Judy isn't hearing the case..... suspect she would toss it out with no solid evidence for each scenario (year, trim, battery pack, etc) showing the measured performance data, standing on "seat of my pants" claims wouldn't go anywhere.

 

[ClevelandBeemer]

I don't need #'s to Feel the difference. It is That noticeable and now I have proof with my own eyes what happened. The truck literally changed from sport mode to normal mode on it's own. I mentioned I watched it with my own eyes in my other post, how'd you miss that?

Didn’t miss that at all. Again, going from sport to normal involuntarily or not doesn’t make the truck slower……

Ford can limit your speed. However you’ve presented zero evidence to show that your truck is slower…… Btw the power curve is the same for all drive modes, the main difference is throttle response.

And as soon as I invent time travel I will go back in time to test both my 23, which I no longer own, and my current 24 and update this thread.

You could do that, or you could test your current 2024 truck which you feel is slower. The expected 0 to 60 is a known quantity. Not sure why it’s so difficult.

It’s difficult because the power on takeoff (the throw you back in your seat feeling) feels different in this truck vs my old one. I can’t make a comparison because I don’t have my old truck to test against. I could compare it against others but those won’t necessarily be the same comparison unless it’s the same model year and software level.

Had I test drove my new truck extensively prior to purchase I would have gone back and done some side by sides, but I bought out of state and since I already owned a Lightning, I did the deal without driving in advance of pickup. It is what it is.

I’m not sure why you’re white knighting so hard for Ford here. Manufacturers make small changes all the time from model year to model year. It’s absolutely plausible that small changes in throttle response were made. I’m simply adding another voice to the chorus of others who have noticed similar things.

 

[ClevelandBeemer]

Let me see if I can simplify this so you understand, I was looking at the screen when the truck changed modes from sport to normal, are you with me so far? Ok just so we're clear, the truck changed from sport to normal with no input from me. Glad that's out of the way.

As far as power increase or loss, I never stated that, I stated exactly what the owners manual describes when changing modes, you should read it sometime and save us all a lot of time.

Speaking of reading, you should read my comments to you. Nowhere do I question that the drive mode changed on its own, so not sure why you keep litigating it…..

However what I keep pointing out is there is NO change in available power between normal and sport. However your comment said when you noticed the change and switched back to sport you “felt the same power you felt from day 1.” I don’t know what you felt on day one but both modes deliver the same mount of power. What you’re feeling is a change in throttle mapping…

I’m not white knighting Ford. I’m asking for hard data because your claim has ton of opportunity for error. Again we know how fast 2022, 2023, 2024, and 2025 trucks are supposed to be. So why not validate your theory? It’s pretty easy to show your 2024 is slower than advertised.

I’ll throw this out as well, testing it improving that it’s slower than it should be is also something to bring to your service advisor when you do your warranty claim.

At one point I felt my S1000R was getting slower after a few years of ownership. It turns out, I just became used to the acceleration. As it still runs a faster 1/4 mile than advertised.

 

[ClevelandBeemer]

I have the distinct feeling we're discussing two different things within the same subject matter. Have to say in my case there is no missing power so much as it is misrouted power.

So I went back through the last page or two and I see where the potential misunderstanding is. I take it you’ve edited some of your comments after posting? I swear upon initial read, some of the context currently there was not present.

I’m in total agreement normal and sport absolutely feel different and it would be apparent if you were expecting one mode but were in another. This is also very much what the OP and Maineiac12 are likely feeling.

From personal experience - I have driven and drive in Sport Mode 99% of the time. For fun; I had initially gauged my 0-60mph time after purchasing in March of this year to see how close this '24 Flash was to the advertised 3.8 seconds. This was a pretty consistent 4.1-4.2 second 0-60mph times on a very slight downhill, but even grade. I tested this again yesterday several times and was getting consistent 4.6-4.7 second 0-60mph times. It was in fact colder outside yesterday than when I did this same 'test' in March/April.

This is good stuff right here! So a few things, you’re getting 4.1-4.2 0-60MPH because you’re likely calculating without the 1ft rollout that Ford utilizes. When you remove the 1ft rollout you get a 0-60MPH run in ~4.16 seconds. So in March you were dead on.

Now for your run yesterday, was the road wet or covered in salt? Was SoC > 80%? Given the temperatures was 100% power available in the gauge cluster? Finally was TC off? Colder temps will certainly impact your times but just curious if there were other mitigating factors.

There is also the fact that the Ford numbers are on a prepped (high traction) surface. Traction control will and does pull power when you try to do a hard launch which will show up in the times and vary based on the amount of traction you have. Remember, even if it isn't cold enough to be impacting the battery or motors, cold tires have less traction! If you haven't yet turn it all the way off (press and hold) and then try a hard launch and see what happens. 4 wheel burn outs are fun!
