2026 GMC Sierra EV AT4 / Denali in Richmond, VA
Winter range, charging cost and how far it goes, worked out for Richmond's weather, grid and prices.
Richmond's winters are cool rather than cold: on a typical January day (38°F) a Sierra EV AT4 / Denali gets an estimated 372 miles, 9% under its 410-mile rating, about the same as in the coldest week (around January 14, when it averages 38°F). By June it's back to about 429. Charging at home at Virginia's average rate (17.5¢/kWh) costs about $102 a month for 38 miles a day, against $271 for a gas Sierra on the Lower Atlantic's gas. And Richmond's grid (SERC Virginia/Carolina), 23% cleaner than the US average, makes it 75% 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 Richmond drivers ask
How far can a Sierra EV AT4 / Denali go in a Richmond winter?
About 372 miles on a typical January day (38°F) and about the same in the coldest week of the year (around January 14, 38°F on average), estimated from real EV drives at those temperatures. That's 9% 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 Richmond?
About $102 a month at home for 38 miles a day, at Virginia's average home electricity rate of 17.5¢/kWh: about 8.8¢ 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 Richmond?
Not at 38 miles a day: a 120 V outlet adds only about 31 miles in 12 hours on an average day (28 in the coldest week). Plan on 240 V, which fills it from 10% in about 17 hours.
Is it greener to drive electric on Richmond's grid?
Yes, more than most places. Richmond's grid (SERC Virginia/Carolina) is 23% cleaner than the US average, so a Sierra EV AT4 / Denali charged on it makes 75% less CO₂ than a gas Sierra.
