It seems like Teslas get way less range when it’s cold, especially the ones without heat pumps. This is no surprise whatsoever but it’s not well covered by EPA range estimates because combustion engines get free heat. So it’s not something people are used to thinking about.
Seems like where Tesla f’d up is by making a team to lie about it instead of just telling people, “yeah that’s what happens.” As usual it’s the cover-up that worse than the crime. Tesla will probably win the case but will look stupid. Should have just been honest about it.
