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

[ClevelandBeemer]

Without data this post isn’t very productive. Have you timed a zero to 60 run?

The simple answer is you’re more accustomed to the acceleration.

Not saying this is it - but is there any way to tell if your truck was enrolled in a fleet program at any one time? My 2024 flash was on a lot/at a dealer for at least 4-5 months before it was traded to my local dealer for my purchasing.....
Fleet Management Features (Smart Acceleration Truncation): For F-150 Lightning Pro commercial models, Ford offers optional features called Smart Acceleration Truncation and Speed Limitation. These features electronically cap the maximum acceleration rate and top speed, forcing more efficient driving behavior to improve battery efficiency and minimize wear and tear.

You’re not imagining things, or getting used to it.

I traded my 23 XLT for a 24 Flash (both ER) and immediately noticed a difference in acceleration on highway ramps. The 24 didn’t have the same low end torque as the 23 off the line.

I don’t think Ford changed the motors so it’s likely a software change that my new truck had from the factory that got applied to yours at some point.

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.

Thanks for sharing your newly gained knowledge. Don't be surprised if you notice a difference in acceleration in 30 to 60 days.... once the new wears off, they may slip in the change in acceleration to hedge their warranty bet.

Thanks for sharing.

Still no data…….

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.

Happened to me today, I remote started climate and got in about 5 mins or so later, started it up and the first thing I always do without hesitation is bring up the mode screen. Changed it to sport and was fiddling with something when I looked up about the same time and watched it with my own eyes, truck already running, foot on brake it changed from my selected sport mode back to normal.

Changed it back to sport a 2nd time and it stuck this time and I had all the same power I remember from day 1 of finding that sport button. Ghost in the machine? lol Any way I'm glad I caught it or I wouldn't have believed it, so yeah I'm going to blame the software updates of late, got 3 of them back to back in as many days.

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.

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...

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?

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.

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.
