2026 Chevrolet Silverado EV Trail Boss in New Haven, CT
Winter range, charging cost and how far it goes, worked out for New Haven's weather, grid and prices.
New Haven's winters are cool rather than cold: on a typical January day (31°F) a Silverado EV Trail Boss gets an estimated 378 miles, 23% under its 493-mile rating, and about 373 in the coldest week (around January 20, when it averages 30°F). By April it's back to about 459. Power is pricey in Connecticut (24.5¢/kWh), so charging at home costs about $160 a month for 38 miles a day, still less than the $286 a gas Silverado costs on New England's gas. And New Haven's grid (NPCC New England), 30% cleaner than the US average, makes it 74% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 117 real drives of this model; the rest come from 2,178 real drives in EVs at each temperature (and Recurrent's winter study below freezing), applied to its 493-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions New Haven drivers ask
How far can a Silverado EV Trail Boss go in a New Haven winter?
About 378 miles on a typical January day (31°F) and about 373 in the coldest week of the year (around January 20, 30°F on average), estimated from real EV drives at those temperatures. That's 23–24% below its 493-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 Silverado EV Trail Boss in New Haven?
About $160 a month at home for 38 miles a day, at Connecticut's average home electricity rate of 24.5¢/kWh: about 13.8¢ a mile. A gas Silverado on New England's average gas ($4.20 a gallon) costs about $286 a month for the same driving.
Can I charge a Silverado EV Trail Boss on a regular 120 V outlet in New Haven?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (24 in the coldest week). Plan on 240 V, which fills it from 10% in about 12 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 Silverado EV Trail Boss charged on it makes 74% less CO₂ than a gas Silverado.
