2026 GMC Sierra EV AT4 / Denali in Omaha, NE
Winter range, charging cost and how far it goes, worked out for Omaha's weather, grid and prices.
In a typical Omaha January (23°F), a Sierra EV AT4 / Denali gets an estimated 317 miles on a charge, 23% less than its 410-mile rating, and about the same in the coldest week of the year (around January 9, when it averages 23°F). By June it's back to about 424. Charging at home at Nebraska's average rate (13.8¢/kWh) costs about $84 a month for 38 miles a day, about a third of the $291 a gas Sierra costs on the Midwest's gas. Omaha's grid (MRO West) is 20% dirtier than the US average, but charging on it still makes 59% 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 Omaha drivers ask
How far can a Sierra EV AT4 / Denali go in a Omaha winter?
About 317 miles on a typical January day (23°F) and about the same in the coldest week of the year (around January 9, 23°F on average), estimated from real EV drives at those temperatures. That's 23% below its 410-mile rating, mostly from heating the cabin and the battery. Omaha averages 82 days a year below freezing.
How much does it cost to charge a Sierra EV AT4 / Denali in Omaha?
About $84 a month at home for 38 miles a day, at Nebraska's average home electricity rate of 13.8¢/kWh: about 7.3¢ a mile. A gas Sierra on the Midwest's average gas ($4.14 a gallon) costs about $291 a month for the same driving.
Can I charge a Sierra EV AT4 / Denali on a regular 120 V outlet in Omaha?
Not at 38 miles a day: a 120 V outlet adds only about 30 miles in 12 hours on an average day (24 in the coldest week). Plan on 240 V, which fills it from 10% in about 17 hours.
Is it greener to drive electric on Omaha's grid?
Yes. Omaha's grid (MRO West) is 20% dirtier than the US average, but a Sierra EV AT4 / Denali charged on it still makes 59% less CO₂ than a gas Sierra.
