Partly estimated: 117 real drives of this model so far.
Until its owners log enough real drives, range is worked out from 1,548 real drives in EVs (117 of them this model's) at each temperature, as a share of their own EPA ratings, applied to its 410-mile rating. Where PlugLog doesn't have enough cold-weather drives yet, it uses Recurrent's winter range study (30,000+ US EVs over several winters: 78% of ideal-weather range at 32°F, 70% at 20°F), applied to PlugLog's warm-weather drives. Each temperature band switches to real data from this model on its own once it has 20 drives from 3 drivers, and its label changes.

In the cold, most of the range lost goes to heating the cabin and the battery, and a cold battery charges slower until it warms. Precondition before a fast-charging stop.
Your week, on one chargeEstimated
38 mi a day at 20°F, plugging in overnight at home on 240 V the night before a day that would end under 20%. The orange days follow a night plugged in.
At 38 mi a day, a regular wall outlet falls behind at 20°F: plan on 240 V, or some public charging.
