So we all know that colder weather will impact the range/consumption.. It's a fact
We also know that the GOM isn't perfect, it's a tool to help you estimate, nothing more.
People should stop panicking when they see the estimated range and do a real analysis based on numbers they are sure about!
Here's my little fact finding
RWD regular battery, I'm in Canada near Ottawa
Since we got the car in June, my wife had been using it to get to work. 70km trip in total each day and that used up 14% of the battery. By extrapolating the GOM predicted range on a 100% charge I was getting 425-435km.
Recently the temperatures have gone down below freezing in morning and in the 6-10C in the afternoon. The estimated range has dropped drastically to about 300km extrapolated on a 100% charge. That seems really major BUT... the % used for the same daily trip only increased to 16%. Car sleeps in an unheated garage at this time.
It is pretty obvious that the car is trying to adapt its GOM math to the lower temperatures and it is being extra conservative (which in my opinion is a good thing)
In numbers ...
425km... equals a consumption of 16kWh/100km... but the trip actually used only 13.6 (for 14% of the battery)
300km, that's equal to 23kWh/100km but actual consumption at 16% battery usage is only 16kWh/100km
A lot of info, my math brain showing up to the chat but all this to show that the car is highly overestimating the impacts of colder weather on range.
Wanted to share my findings and tell the range anxiety sufferer to look at real data not GOM facts ..
