I know this is a common-ish question here but here goes. I’ve had this car for less than a week, technically bought used but only had 1000 miles on it. For reference, here are my driving conditions:
Central coast of California where mornings are ~40F and afternoons are ~70F. I commute ~140 miles a day for work. I’ve driven round trip from work twice now. The first time I drove to work was definitely fast (80mph) and then I realized how much speed influences my estimated mileage so I’ve slowed down to ~70mph. My 70-ish mile drive to work has cost me about 100 miles of range with about 2.1mi/kWh efficiency.
Today was only the second time I’ve charged it and after charging to 90% my estimated range was only 214mi. I know that the estimated range changes based on recent driving but being 65 miles below the expected mileage at 90% was concerning. However my efficiency increased a lot on the way home to >3.0 mi/kWh.
Has anyone else experienced this?
Edit: I also want to add that this change happened very suddenly between my morning commute to work and my drive home. My drive to work used almost 100 miles of range with 2.1mi/kWh efficiency. My drive home used about 65 miles of range with 3.2 mi/kWh efficiency.
The displayed range on startup is really just based on your current average efficiency + exterior temperature. It dropping precipitously under those circumstances isn’t concerning.
Overall, I’d focus on how much % SOC you use and get a feel for your commute rather than worrying about displayed range. That’s just the car trying to estimate based on external factors and isn’t worth worrying too much about until you’ve got quite a few miles on the car and it’s got a better estimate of your averages.
