2026 GMC Sierra EV AT4 / Denali in Ogden, UT
Winter range, charging cost and how far it goes, worked out for Ogden's weather, grid and prices.
In a typical Ogden January (29°F), a Sierra EV AT4 / Denali gets an estimated 336 miles on a charge, 18% less than its 410-mile rating, and about the same in the coldest week of the year (around December 30, when it averages 28°F). By June it's back to about 419. Charging at home at Utah's average rate (13.1¢/kWh) costs about $80 a month for 38 miles a day, about a third of the $313 a gas Sierra costs on the Rocky Mountains's gas. And Ogden's grid (WECC Northwest), 18% cleaner than the US average, makes it 72% 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 Ogden drivers ask
How far can a Sierra EV AT4 / Denali go in a Ogden winter?
About 336 miles on a typical January day (29°F) and about the same in the coldest week of the year (around December 30, 28°F on average), estimated from real EV drives at those temperatures. That's 18% below its 410-mile rating, mostly from heating the cabin and the battery. Ogden averages 68 days a year below freezing.
How much does it cost to charge a Sierra EV AT4 / Denali in Ogden?
About $80 a month at home for 38 miles a day, at Utah's average home electricity rate of 13.1¢/kWh: about 6.9¢ a mile. A gas Sierra on the Rocky Mountains's average gas ($4.47 a gallon) costs about $313 a month for the same driving.
Can I charge a Sierra EV AT4 / Denali on a regular 120 V outlet in Ogden?
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 Ogden's grid?
Yes, more than most places. Ogden's grid (WECC Northwest) is 18% cleaner than the US average, so a Sierra EV AT4 / Denali charged on it makes 72% less CO₂ than a gas Sierra.
