Questions Hartford drivers ask
How far can a Prologue go in a Hartford winter?
About 218 miles on a typical January day (29°F) and about the same in the coldest week of the year (around January 21, 28°F on average), estimated from real EV drives at those temperatures. That's 20% below its 273-mile rating, mostly from heating the cabin and the battery. Hartford averages 60 days a year below freezing.
How much does it cost to charge a Prologue in Hartford?
About $110 a month at home for 38 miles a day, at Connecticut's average home electricity rate of 24.2¢/kWh: about 9.6¢ a mile. An average standard SUV on New England's average gas ($4.25 a gallon) costs about $289 a month for the same driving.
Can I charge a Prologue on a regular 120 V outlet in Hartford?
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 33 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 Hartford's grid?
Yes, more than most places. Hartford's grid (NPCC New England) is 30% cleaner than the US average, so a Prologue charged on it makes 82% less CO₂ than an average standard SUV.
