2026 GMC Sierra EV AT4 / Denali in Pittsburgh, PA
Winter range, charging cost and how far it goes, worked out for Pittsburgh's weather, grid and prices.
In a typical Pittsburgh January (30°F), a Sierra EV AT4 / Denali gets an estimated 339 miles on a charge, 17% less than its 410-mile rating, and about the same in the coldest week of the year (around January 18, when it averages 29°F). By June it's back to about 421. Charging at home at Pennsylvania's average rate (21.7¢/kWh) costs about $131 a month for 38 miles a day, against $302 for a gas Sierra on the Central Atlantic's gas. Pittsburgh's grid (RFC West) is 19% dirtier than the US average, but charging on it still makes 60% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 117 real drives of this model; the rest come from 1,548 real drives in EVs at each temperature (and Recurrent's winter study below freezing), applied to its 410-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Pittsburgh drivers ask
How far can a Sierra EV AT4 / Denali go in a Pittsburgh winter?
About 339 miles on a typical January day (30°F) and about the same in the coldest week of the year (around January 18, 29°F on average), estimated from real EV drives at those temperatures. That's 17% below its 410-mile rating, mostly from heating the cabin and the battery. Pittsburgh averages 50 days a year below freezing.
How much does it cost to charge a Sierra EV AT4 / Denali in Pittsburgh?
About $131 a month at home for 38 miles a day, at Pennsylvania's average home electricity rate of 21.7¢/kWh: about 11.3¢ a mile. A gas Sierra on the Central Atlantic'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 Pittsburgh?
Not at 38 miles a day: a 120 V outlet adds only about 30 miles in 12 hours on an average day (26 in the coldest week). Plan on 240 V, which fills it from 10% in about 17 hours.
Is it greener to drive electric on Pittsburgh's grid?
Yes. Pittsburgh's grid (RFC West) is 19% dirtier than the US average, but a Sierra EV AT4 / Denali charged on it still makes 60% less CO₂ than a gas Sierra.
