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

[cowboys1870]

I did a fairly unscientific test on Oklahoma roads of my 0-60, and measured kW and motor torque via OBD2 scanner.

BLUF: My 2022 SR is accelerating 0-60 as fast as ever, ~4.6 seconds. I am also putting down 770 lb-ft of torque (Ford adversities 775), and battery was supplying 370 kW (Ford advertises 318 to the motors).

There is a potential for software learning I would suspect, but I also suspect that at least part of it could be that you are not using brand new tires anymore. The stock tires a what many dealerships call 'softies', which are super grippy and soft for extra performance and quiet ride, which make the vehicle easier to sell. If you had great acceleration on new tires, then they wear a bit, performance suffers a bit too..... NASCAR is a good example of this. Even if you do replace your tires, you likely won't use softies, thus changing your grip and performance with it, although they will likely last longer (something the dealership wouldn't care about).
Tires + Software learning = slight delay of sudden acceleration.

You're....

Thank you.

The truck may be just as fast as before, but the best way I'd describe it is that it requires more throttle input to get the same amount of power. It feels like the pedal has been detuned just a little.
For me it's not a problem, just a curiosity. I don't drive mine hard all the time any way.

OP, if there is someone you trust to drive the vehicle, get in the passenger seat.

I don't smash the accelerator from a standstill because I don't like that front end torque steer fight. If you don't have that, indeed your power is cut.

There is also a quick power drop out at around 70 to 80mph and it is a reminiscent feeling of a transmission finally changing a held gear at high RPM.

The only time I noticed any sort of power change is when I forget to hit OK to continue in Sport mode.

You may want to check your drive modes screen to make sure you are not having the issue where you can't select a different drive mode.

Wow, I noticed my '24 Flash was feeling sluggish after I took it in for the GSM recall and had the tech update all modules with pending updates. (this is what almost completely has eliminated the acceleration shudder/stutter) The shudder has been 'tightened' and is much less noticeable for me. I would be willing to guesstimate that this has something to do with it - Who has the Dyno charts from before?

I also think this is just you getting used to the speed and it starting to feel slow. Mine feels a bit slower as well, but so did my previous Model 3 Performance after driving it for years. You just get really used to it and it does not feel as quick. When I have people in the car and I floor it they are all still impressed.

If you want to have a serious conversation about this, numbers are needed. Take it to the drag strip and get some times with some fresh tires. "Feeling" is impossible to quantify and the conversation will just go in circles.

You're....

I wouldn't quite call myself the Grammar Police, but this drives me nuts when I see it. There's a lot that bugs me... like when people use "then" instead of "than", ha ha.

My 23 Lightning has 33k miles and I cannot tell a difference... same insane torque and power. It's just that people get used to it and acceleration feels like it's less than before.

Do you have your fob? When I used my phone as a key without the fob I got limited to 80 mph on the highway. I don't drive it hard so I don't know if it limited my acceleration. I finally found a setting in the big menu that let me turn off child proofing the car and that fixed the 80 mph limit. But I still take the fob when I can remember it.

Total guess - you might get a check of your battery in case a cell is failing. I would expect the truck to warn you but maybe there is just a small voltage drop that it does not alarm on.

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.

 

[blb228]

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…….
