Questions Hartford drivers ask
How far can a Silverado EV 4WT go in a Hartford winter?
About 364 miles on a typical January day (29°F) and about 360 in the coldest week of the year (around January 21, 28°F on average), estimated from real EV drives at those temperatures. That's 19–20% below its 450-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 Silverado EV 4WT in Hartford?
About $158 a month at home for 38 miles a day, at Connecticut's average home electricity rate of 24.2¢/kWh: about 13.6¢ a mile. A gas Silverado on New England's average gas ($4.25 a gallon) costs about $289 a month for the same driving.
Can I charge a Silverado EV 4WT on a regular 120 V outlet in Hartford?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (23 in the coldest week). Plan on 240 V, which fills it from 10% in about 11 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 Silverado EV 4WT charged on it makes 74% less CO₂ than a gas Silverado.
