Winter range, charging cost and how far it goes, worked out for Seattle's weather, grid and prices.
Winter barely touches range in Seattle: at a typical January's 42°F, an Equinox EV gets an estimated 288 miles on a charge, within 6% of its 307-mile rating. Charging at home at Washington's average rate (14.7¢/kWh) costs about $56 a month for 38 miles a day, about a third of the $246 a gas Equinox costs on Seattle's gas.

Questions Seattle drivers ask
How far can an Equinox EV go in a Seattle winter?
Seattle's winters are mild: about 288 miles on a typical January day (42°F) and about the same in the coldest week (around December 19, 41°F), estimated from real EV drives at those temperatures. That's within 7% of its 307-mile rating.
How much does it cost to charge an Equinox EV in Seattle?
About $56 a month at home for 38 miles a day, at Washington's average home electricity rate of 14.7¢/kWh: about 4.9¢ a mile. A gas Equinox on Seattle's average gas ($5.53 a gallon) costs about $246 a month for the same driving.
Can I charge an Equinox EV on a regular 120 V outlet in Seattle?
At 38 miles a day, yes, all year: a 120 V outlet adds about 44 miles in 12 hours even in Seattle's coldest week, and about 48 on an average day.
Is it greener to drive electric on Seattle's grid?
Yes, more than most places. Seattle's grid (WECC Northwest) is 18% cleaner than the US average, so an Equinox EV charged on it makes 72% less CO₂ than a gas Equinox.
