Hey Everyone, I just have a quick question regarding efficiency with winter tires/winter driving in general in a model 3.
Post is kinda long so here's the TL;DR
Summer consumption = 130Wh/km
Consumption prior to winter tire switch and update to 2019.36.1 = 170Wh/km
After tire switch and update = 190-200Wh/km
Is this normal?
Full Post:
I have a Model 3 SR+ with 18" wheels (w/ FSD).
I recently installed the factory winter tire package with 18" Aero rims (without cap) and Pirelli Sottozero 2 (Tesla spec) tires.
I noticed my daily commute average consumption just prior to switching to winter tires was roughly 170Wh/km (down from the 130Wh/km in summer).
I switched tires on the same day as getting the 2019.36.1 update which was "supposed to improve efficiency and power in model 3s by up to 5%".
Immediately after the switch, I noticed my consumption has increased to about 190Wh/km and with the recent cold spell in the GTA area over the last couple days, it's hitting nearly 200Wh/km (this is averaged out between morning and evening commute since my morning commute is always more efficienty from driving downhill).
Now, I realize the temperatures have also dropped by a few degrees over the last few days, but it shouldn't explain the sudden 12% increase in consumption, especially since the software update was supposed to increase fuel efficiency.
I plan on getting a car wash this weekend then installing the Aero caps in hopes of lowering the consumption, even if only by a few %.
Just wondering what others on this forum has been getting in terms of consumption after switch over to winter tires, and driving in cold weather in general. Is my consumption increase in the normal range? Or should I be concerned?
Just as a side note: driving back from downtown to richmond hill yesterday yielded an average trip consumption of 230Wh/km. I was hoping even in worst case scenario in winter, I'd get half my range, but at this rate, it seems I'd have even less than half during a bad winter storm.
