Questions Seattle drivers ask
How far can a Prologue go in a Seattle winter?
Seattle's winters are mild: about 256 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 273-mile rating.
How much does it cost to charge a Prologue in Seattle?
About $65 a month at home for 38 miles a day, at Washington's average home electricity rate of 14.7¢/kWh: about 5.6¢ a mile. An average standard SUV on Seattle's average gas ($5.53 a gallon) costs about $376 a month for the same driving.
Can I charge a Prologue on a regular 120 V outlet in Seattle?
At 38 miles a day, yes, all year: a 120 V outlet adds about 39 miles in 12 hours even in Seattle's coldest week, and about 41 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 a Prologue charged on it makes 79% less CO₂ than an average standard SUV.
