2025 GMC Sierra EV 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 gets an estimated 313 miles, 20% under its 390-mile rating, and about 309 in the coldest week (around December 27, when it averages 31°F). By April it's back to about 377. Charging at home at Utah's average rate (13.1¢/kWh) costs about $87 a month for 38 miles a day, about a third of the $323 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 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 Salt Lake City drivers ask
How far can a Sierra EV go in a Salt Lake City winter?
About 313 miles on a typical January day (31°F) and about 309 in the coldest week of the year (around December 27, 31°F on average), estimated from real EV drives at those temperatures. That's 20–21% below its 390-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 in Salt Lake City?
About $87 a month at home for 38 miles a day, at Utah's average home electricity rate of 13.1¢/kWh: about 7.5¢ 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 Salt Lake City?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (24 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 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 charged on it makes 70% less CO₂ than a gas Sierra.
