2024 Honda Prologue in Dayton, OH
Winter range, charging cost and how far it goes, worked out for Dayton's weather, grid and prices.
Dayton's winters are cool rather than cold: on a typical January day (29°F) a Prologue gets an estimated 220 miles, 19% under its 273-mile rating, about the same as in the coldest week (around January 18, when it averages 29°F). By April it's back to about 266. Charging at home at Ohio's average rate (19.4¢/kWh) costs about $88 a month for 38 miles a day, about a third of the $275 an average standard SUV costs on Ohio's gas.

Questions Dayton drivers ask
How far can a Prologue go in a Dayton winter?
About 220 miles on a typical January day (29°F) and about the same in the coldest week of the year (around January 18, 29°F on average), estimated from real EV drives at those temperatures. That's 19% below its 273-mile rating, mostly from heating the cabin and the battery. Dayton averages 48 days a year below freezing.
How much does it cost to charge a Prologue in Dayton?
About $88 a month at home for 38 miles a day, at Ohio's average home electricity rate of 19.4¢/kWh: about 7.6¢ a mile. An average standard SUV on Ohio's average gas ($4.05 a gallon) costs about $275 a month for the same driving.
Can I charge a Prologue on a regular 120 V outlet in Dayton?
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 34 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 Dayton's grid?
Yes. Dayton's grid (RFC West) is 19% dirtier than the US average, but a Prologue charged on it still makes 69% less CO₂ than an average standard SUV.
