2026 Chevrolet Silverado EV Trail Boss in Boise, ID
Winter range, charging cost and how far it goes, worked out for Boise's weather, grid and prices.
Boise's winters are cool rather than cold: on a typical January day (32°F) a Silverado EV Trail Boss gets an estimated 390 miles, 21% under its 493-mile rating, and about 380 in the coldest week (around December 24, when it averages 31°F). By March it's back to about 458. Charging at home at Idaho's average rate (13.4¢/kWh) costs about $87 a month for 38 miles a day, about a third of the $303 a gas Silverado costs on the Rocky Mountains's gas. And Boise's grid (WECC Northwest), 18% cleaner than the US average, makes it 69% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 117 real drives of this model; the rest come from 2,178 real drives in EVs at each temperature (and Recurrent's winter study below freezing), applied to its 493-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Boise drivers ask
How far can a Silverado EV Trail Boss go in a Boise winter?
About 390 miles on a typical January day (32°F) and about 380 in the coldest week of the year (around December 24, 31°F on average), estimated from real EV drives at those temperatures. That's 21–23% below its 493-mile rating, mostly from heating the cabin and the battery. Boise averages 33 days a year below freezing.
How much does it cost to charge a Silverado EV Trail Boss in Boise?
About $87 a month at home for 38 miles a day, at Idaho's average home electricity rate of 13.4¢/kWh: about 7.5¢ a mile. A gas Silverado on the Rocky Mountains's average gas ($4.46 a gallon) costs about $303 a month for the same driving.
Can I charge a Silverado EV Trail Boss on a regular 120 V outlet in Boise?
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 12 hours.
Is it greener to drive electric on Boise's grid?
Yes, more than most places. Boise's grid (WECC Northwest) is 18% cleaner than the US average, so a Silverado EV Trail Boss charged on it makes 69% less CO₂ than a gas Silverado.
