GTPE 0-60 in 3.5? Mine goes 0-60 in about 5.

Seems like my GTPE is slower than it used to be. I did have the HVB issue and it was fixed. Is this just in my head, or could my car actually be slower than it was when I first got it.

State of charge and temperature outside?

Cold temps and low charge could I’m theory make you that slow.

But if it’s not those things….. post a video.

Easiest way I could see if power is missing would be based on traction. My GTPE spins the tires if I floor it at any speed under 30 mph. Does yours?

The grip needs to be there, otherwise it spins, agree.
Slightly wet road, any gravel on the road, colder weather (not ice or snow) etc will spin them up to 70-80 km/h easily if you floor it. Dry road 25c 100% charge and summer tires on, it will still spin if I floor it from standstill and maybe up to ~30 km/h. I have updated the HVB and feel 0 difference before compared to after in terms of acceleration.

Not sure what’s slower. The OPs car or their response time on the forum.

Yes.

Now that my tires are more worn, and its colder and wetter outside, I spin my tires more. Slower? Yes, But much more fun.

Oh I didn't see a question. Thanks for the feedback guys.

So now that you’ve seen the questions (post #2), what are your answers?

Hard to help if we don’t know what’s going on.

Also to get 3.5 seconds you need to be close to 100% charge, or at least above 80%. I have not tested to see where the power limiting starts, but if you want to get the best times you need a full charge.

It doesn't seem like it's spinning tires or cold temps in the tires. What I learned here from the responses is that charge percentage matters and Ford recommends 90% charge when on the track. As my daily driver, I'm around 60% charge so that might be the culprit.

Check for the "jail bars" below your SoC display where the blue/green bars appear to display your power use and regen. If there are little grey bars, this means your power is restricted. As others mentioned, this could be due to external factors like temp but occasionally, I've had mine show up with nearly half the power restricted. After a shutdown + wait a few minutes + restart of the car, things went back to normal.

Yesterday I noticed I had a grey bar at 77% charge.

I've seen similar as well. I always have a couple grey bars (frustrating) but occasionally I have nearly 50% power restriction.

Even with better tires I still spin the front. I drive pretty aggressive. Once my shop is done I'll be dropping the batt and doubling the busbars in it as well as hunting out a way to remove the limits. It will likely require a device to intercept what the vehicle's brains are receiving and trick them into believing that 100% is only 70%. The goal is to decipher the variables being watched and trick it into giving 100% of the power whenever called upon. It's been said the limiting variable is the battery busbars. I'll first install several temp probes on them to see if that's in-fact the issue.

Furthermore, the motors in the MME have a max speed of ~205 mph with the stock tires. Ford sells the motor and other components of the MME so that they can be used in ICE to BEV conversions. The dual motor units have 562hp and 634ftlb of torque capability as they sit in the vehicle, limited by other variables.

Are you serious about modifying the bus bars and BMS operation? I worry about your safety but would love to see a thread on your progress if you want to share it.
