2026 GMC Sierra EV AT4 / Denali in Salt Lake City, UT
Winter range, charging cost and how far it goes, worked out for Salt Lake City's weather, grid and prices.
Salt Lake City's winters are cool rather than cold: on a typical January day (31°F) a Sierra EV AT4 / Denali gets an estimated 347 miles, 15% under its 410-mile rating, and about 344 in the coldest week (around December 27, when it averages 31°F). By June it's back to about 424. Charging at home at Utah's average rate (13.1¢/kWh) costs about $79 a month for 38 miles a day, about a third of the $313 a gas Sierra costs on the Rocky Mountains's gas. And Salt Lake City'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 Salt Lake City drivers ask
How far can a Sierra EV AT4 / Denali go in a Salt Lake City winter?
About 347 miles on a typical January day (31°F) and about 344 in the coldest week of the year (around December 27, 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. Salt Lake City averages 41 days a year below freezing.
How much does it cost to charge a Sierra EV AT4 / Denali in Salt Lake City?
About $79 a month at home for 38 miles a day, at Utah's average home electricity rate of 13.1¢/kWh: about 6.8¢ 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 Salt Lake City?
Not at 38 miles a day: a 120 V outlet adds only about 31 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 Salt Lake City's grid?
Yes, more than most places. Salt Lake City'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.
