Insane energy consumption + estimated range drop

What would cause this sort of spike? Not a track driver, this was on a regular drive on city streets.

What year model Tesla, and version? A spike like that looks to me like a cold battery with resistive heat on.

Or could be a bug. See this Post

2023 Model 3P.

Yeah, that's definitely what it is. Thanks for pointing me in the right direction.

I guess I'll toss my possibilities out there...

1. Routed to a supercharger and the car initiated battery preconditioning.
2. The spike was at the beginning of the drive and HVAC set point commanded cabin heat.
3. The spike happened during the drive because HVAC set point was changed....which commanded cabin heat.
4. You decided to do some extended drag racing.

I'm sure some other possibility will come to mind...

This happened just after 2023.6.8?

I've seen the same thing on occasion. It's real and perfectly fine, it's just that you're looking at a tiny snapshot of ~2 miles of driving where the power consumption was extra high due to some combination of low speed and/or climate/conditioning effects.

Same happens to mine (Model 3 SR+ 2019).
I think it's a bug because before the last software update, my estimated range was always above 100% than the rated range.
Now it's around 60% (20+ kWh/100 km average un the Energy App) and I have not changed my driving, the weather is warming up now here as well.
However, the trip consumption is the same as before the software update (between 9 and 15 kWh/100 km), so that's why I think the Energy App has some kind of bug.

In my case, yes. I think it's a bug.
