2026 GMC Sierra EV AT4 / Denali in Atlanta, GA
Winter range, charging cost and how far it goes, worked out for Atlanta's weather, grid and prices.
Atlanta's winters are cool rather than cold: on a typical January day (44°F) a Sierra EV AT4 / Denali gets an estimated 386 miles, 6% under its 410-mile rating, about the same as in the coldest week (around January 9, when it averages 43°F). By May it's back to about 421. Charging at home at Georgia's average rate (16.3¢/kWh) costs about $93 a month for 38 miles a day, against $271 for a gas Sierra on the Lower Atlantic's gas. Atlanta's grid (SERC South) is 10% dirtier than the US average, but charging on it still makes 65% 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 Atlanta drivers ask
How far can a Sierra EV AT4 / Denali go in a Atlanta winter?
About 386 miles on a typical January day (44°F) and about the same in the coldest week of the year (around January 9, 43°F on average), estimated from real EV drives at those temperatures. That's 6% below its 410-mile rating, mostly from heating the cabin and the battery.
How much does it cost to charge a Sierra EV AT4 / Denali in Atlanta?
About $93 a month at home for 38 miles a day, at Georgia's average home electricity rate of 16.3¢/kWh: about 8.1¢ a mile. A gas Sierra on the Lower Atlantic's average gas ($3.86 a gallon) costs about $271 a month for the same driving.
Can I charge a Sierra EV AT4 / Denali on a regular 120 V outlet in Atlanta?
Not at 38 miles a day: a 120 V outlet adds only about 31 miles in 12 hours on an average day (29 in the coldest week). Plan on 240 V, which fills it from 10% in about 17 hours.
Is it greener to drive electric on Atlanta's grid?
Yes. Atlanta's grid (SERC South) is 10% dirtier than the US average, but a Sierra EV AT4 / Denali charged on it still makes 65% less CO₂ than a gas Sierra.
