Guys tracking/auto-xing Model 3s - what's your battery degradation like?

Just wondering. Events/year & mileage might also help put things into perspective.

Random anecdote - I've noticed that driving uphill sometimes seems to draw more energy than bouts of spirited driving.

I only ever use % so I have no idea. It's good for my mental health

Seems to be a negligible affect. Was sitting at ~10% on both 2018's, but that kind of seems par for the course.

Word. I think wheel configuration might impact it, also.

On the bright side, it's definitely not having any sort of detrimental affect, so that's certainly good news!

Yeah, your wheel config does change the estimated range, and Tesla has also tweaked these models between SW releases.
The only real way is looking at the BMS estimate of max energy, but that needs connections and tools most people don't have. Even that can get off unless it's seen near zero and full charge states recently.

I have noticed that tracking the car seems to make that estimate drift more. I've had it stop charging at 98%, or go for an hour at 100%. Letting the car get near zero and then fully charge seems to recalibrate it.

What I want to know is what kind of energy usage do people get on the track and AutoX?
I personally run just a bit above 2000 wh/mi during AutoX. I've been surprised that tires don't make that much different (stock PS4S. 265 PS4S, 265 RE71, 275 Hoosiers)

14% loss 75,000 miles, 2 years. This is with probably close to fifty 1/2 mile runs, probably double that in 1/4 mile runs and the usual beating that all Teslas receive.

I don't track my car, but I'm not shy about driving the car hard day to day. I'm at 46k on my 2018 dual motor and showing 10% loss (280mi vs 310 new).
