2024 Honda Prologue in Boise, ID
Winter range, charging cost and how far it goes, worked out for Boise's weather, grid and prices.
Boise's winters are cool rather than cold: on a typical January day (32°F) a Prologue gets an estimated 228 miles, 16% under its 273-mile rating, and about 224 in the coldest week (around December 24, when it averages 31°F). By May it's back to about 271. Charging at home at Idaho's average rate (13.7¢/kWh) costs about $62 a month for 38 miles a day, about a third of the $304 an average standard SUV costs on the Rocky Mountains's gas. And Boise's grid (WECC Northwest), 18% cleaner than the US average, makes it 79% less CO₂ than gas.
Partly estimated. 1 of 5 temperature bands are from 83 real drives of this model; the rest come from 1,548 real drives in EVs at each temperature (and Recurrent's winter study below freezing), applied to its 273-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Boise drivers ask
How far can a Prologue go in a Boise winter?
About 228 miles on a typical January day (32°F) and about 224 in the coldest week of the year (around December 24, 31°F on average), estimated from real EV drives at those temperatures. That's 16–18% below its 273-mile rating, mostly from heating the cabin and the battery. Boise averages 33 days a year below freezing.
How much does it cost to charge a Prologue in Boise?
About $62 a month at home for 38 miles a day, at Idaho's average home electricity rate of 13.7¢/kWh: about 5.4¢ a mile. An average standard SUV on the Rocky Mountains's average gas ($4.47 a gallon) costs about $304 a month for the same driving.
Can I charge a Prologue on a regular 120 V outlet in Boise?
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 Boise's grid?
Yes, more than most places. Boise'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.
