2026 GMC Sierra EV AT4 / Denali in Poughkeepsie, NY
Winter range, charging cost and how far it goes, worked out for Poughkeepsie's weather, grid and prices.
In a typical Poughkeepsie January (27°F), a Sierra EV AT4 / Denali gets an estimated 331 miles on a charge, 19% less than its 410-mile rating, and about 328 miles in the coldest week of the year (around January 21, when it averages 27°F). By June it's back to about 419. Power is pricey in New York (29.9¢/kWh), so charging at home costs about $182 a month for 38 miles a day, still less than the $302 a gas Sierra costs on New York's gas. And Poughkeepsie's grid (NPCC Upstate NY), 68% cleaner than the US average, makes it 89% less CO₂ than gas.

Questions Poughkeepsie drivers ask
How far can a Sierra EV AT4 / Denali go in a Poughkeepsie winter?
About 331 miles on a typical January day (27°F) and about 328 in the coldest week of the year (around January 21, 27°F on average), estimated from real EV drives at those temperatures. That's 19–20% below its 410-mile rating, mostly from heating the cabin and the battery. Poughkeepsie averages 72 days a year below freezing.
How much does it cost to charge a Sierra EV AT4 / Denali in Poughkeepsie?
About $182 a month at home for 38 miles a day, at New York's average home electricity rate of 29.9¢/kWh: about 15.8¢ a mile. A gas Sierra on New York's average gas ($4.31 a gallon) costs about $302 a month for the same driving.
Can I charge a Sierra EV AT4 / Denali on a regular 120 V outlet in Poughkeepsie?
Not at 38 miles a day: a 120 V outlet adds only about 30 miles in 12 hours on an average day (25 in the coldest week). Plan on 240 V, which fills it from 10% in about 17 hours.
Is it greener to drive electric on Poughkeepsie's grid?
Yes, more than most places. Poughkeepsie's grid (NPCC Upstate NY) is 68% cleaner than the US average, so a Sierra EV AT4 / Denali charged on it makes 89% less CO₂ than a gas Sierra.
