2024 Honda Prologue in St. Louis, MO
Winter range, charging cost and how far it goes, worked out for St. Louis's weather, grid and prices.
St. Louis'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, about the same as in the coldest week (around January 14, when it averages 32°F). By April it's back to about 268.

St. Louis's grid (SERC Midwest) is 62% dirtier than the US average, but charging on it still makes 58% 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 St. Louis drivers ask
How far can a Prologue go in a St. Louis winter?
About 228 miles on a typical January day (32°F) and about the same in the coldest week of the year (around January 14, 32°F on average), estimated from real EV drives at those temperatures. That's 16% below its 273-mile rating, mostly from heating the cabin and the battery. St. Louis averages 13 days a year below freezing.
How much does it cost to charge a Prologue in St. Louis?
About $72 a month at home for 38 miles a day, at Missouri's average home electricity rate of 16.1¢/kWh: about 6.2¢ a mile. An average standard SUV on the Midwest's average gas ($4.14 a gallon) costs about $282 a month for the same driving.
Can I charge a Prologue on a regular 120 V outlet in St. Louis?
At 38 miles a day, most of the year: a 120 V outlet adds about 42 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 St. Louis's grid?
Yes. St. Louis's grid (SERC Midwest) is 62% dirtier than the US average, but a Prologue charged on it still makes 58% less CO₂ than an average standard SUV.
