2025 GMC Sierra EV 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 gets an estimated 298 miles on a charge, 24% less than its 390-mile rating, and about 294 miles in the coldest week of the year (around December 30, when it averages 28°F). By May it's back to about 386. Charging at home at Utah's average rate (13.1¢/kWh) costs about $88 a month for 38 miles a day, about a third of the $323 a gas Sierra costs on the Rocky Mountains's gas. And Ogden's grid (WECC Northwest), 18% cleaner than the US average, makes it 70% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 116 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 390-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 go in a Ogden winter?
About 298 miles on a typical January day (29°F) and about 294 in the coldest week of the year (around December 30, 28°F on average), estimated from real EV drives at those temperatures. That's 24–25% below its 390-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 in Ogden?
About $88 a month at home for 38 miles a day, at Utah's average home electricity rate of 13.1¢/kWh: about 7.6¢ a mile. A gas Sierra on the Rocky Mountains's average gas ($4.47 a gallon) costs about $323 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Ogden?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (22 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 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 charged on it makes 70% less CO₂ than a gas Sierra.
