2026 GMC Sierra EV AT4 / Denali in Colorado Springs, CO
Winter range, charging cost and how far it goes, worked out for Colorado Springs's weather, grid and prices.
Colorado Springs's winters are cool rather than cold: on a typical January day (32°F) a Sierra EV AT4 / Denali gets an estimated 348 miles, 15% under its 410-mile rating, and about 344 in the coldest week (around December 19, when it averages 31°F). By June it's back to about 418. Charging at home at Colorado's average rate (17.0¢/kWh) costs about $103 a month for 38 miles a day, against $300 for a gas Sierra on Colorado's gas. Colorado Springs's grid (WECC Rockies) is 35% dirtier than the US average, but charging on it still makes 54% 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 Colorado Springs drivers ask
How far can a Sierra EV AT4 / Denali go in a Colorado Springs winter?
About 348 miles on a typical January day (32°F) and about 344 in the coldest week of the year (around December 19, 31°F on average), estimated from real EV drives at those temperatures. That's 15–16% below its 410-mile rating, mostly from heating the cabin and the battery. Colorado Springs averages 57 days a year below freezing.
How much does it cost to charge a Sierra EV AT4 / Denali in Colorado Springs?
About $103 a month at home for 38 miles a day, at Colorado's average home electricity rate of 17.0¢/kWh: about 8.9¢ a mile. A gas Sierra on Colorado's average gas ($4.27 a gallon) costs about $300 a month for the same driving.
Can I charge a Sierra EV AT4 / Denali on a regular 120 V outlet in Colorado Springs?
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 Colorado Springs's grid?
Yes. Colorado Springs's grid (WECC Rockies) is 35% dirtier than the US average, but a Sierra EV AT4 / Denali charged on it still makes 54% less CO₂ than a gas Sierra.
