2024 Honda Prologue in Spokane, WA
Winter range, charging cost and how far it goes, worked out for Spokane's weather, grid and prices.
Spokane's winters are cool rather than cold: on a typical January day (32°F) a Prologue gets an estimated 227 miles, 17% under its 273-mile rating, and about 223 in the coldest week (around December 21, when it averages 31°F). By May it's back to about 269. Charging at home at Washington's average rate (14.7¢/kWh) costs about $67 a month for 38 miles a day, about a third of the $363 an average standard SUV costs on Washington's gas. And Spokane's grid (WECC Northwest), 18% cleaner than the US average, makes it 78% less CO₂ than gas.

Questions Spokane drivers ask
How far can a Prologue go in a Spokane winter?
About 227 miles on a typical January day (32°F) and about 223 in the coldest week of the year (around December 21, 31°F on average), estimated from real EV drives at those temperatures. That's 17–18% below its 273-mile rating, mostly from heating the cabin and the battery. Spokane averages 41 days a year below freezing.
How much does it cost to charge a Prologue in Spokane?
About $67 a month at home for 38 miles a day, at Washington's average home electricity rate of 14.7¢/kWh: about 5.8¢ a mile. An average standard SUV on Washington's average gas ($5.33 a gallon) costs about $363 a month for the same driving.
Can I charge a Prologue on a regular 120 V outlet in Spokane?
At 38 miles a day, most of the year: a 120 V outlet adds about 41 miles in 12 hours on an average day, but about 35 in the coldest week, so it can fall a little behind then. A 240 V outlet fills it from 10% in about 9 hours.
Is it greener to drive electric on Spokane's grid?
Yes, more than most places. Spokane's grid (WECC Northwest) is 18% cleaner than the US average, so a Prologue charged on it makes 78% less CO₂ than an average standard SUV.
