Questions New Haven drivers ask
How far can a Prologue go in a New Haven winter?
About 223 miles on a typical January day (31°F) and about the same in the coldest week of the year (around January 20, 30°F on average), estimated from real EV drives at those temperatures. That's 18% below its 273-mile rating, mostly from heating the cabin and the battery. New Haven averages 43 days a year below freezing.
How much does it cost to charge a Prologue in New Haven?
About $110 a month at home for 38 miles a day, at Connecticut's average home electricity rate of 24.2¢/kWh: about 9.5¢ 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 New Haven?
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 New Haven's grid?
Yes, more than most places. New Haven'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.
