2026 Chevrolet Silverado EV Trail Boss in Denver, CO
Winter range, charging cost and how far it goes, worked out for Denver's weather, grid and prices.
Denver'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 381 in the coldest week (around December 19, when it averages 31°F). By March it's back to about 457. Charging at home at Colorado's average rate (17.2¢/kWh) costs about $112 a month for 38 miles a day, against $300 for a gas Silverado on Denver's gas. Denver's grid (WECC Rockies) is 35% dirtier than the US average, but charging on it still makes 49% less CO₂ than gas.

Questions Denver drivers ask
How far can a Silverado EV Trail Boss go in a Denver winter?
About 390 miles on a typical January day (32°F) and about 381 in the coldest week of the year (around December 19, 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. Denver averages 29 days a year below freezing.
How much does it cost to charge a Silverado EV Trail Boss in Denver?
About $112 a month at home for 38 miles a day, at Colorado's average home electricity rate of 17.2¢/kWh: about 9.7¢ a mile. A gas Silverado on Denver's average gas ($4.41 a gallon) costs about $300 a month for the same driving.
Can I charge a Silverado EV Trail Boss on a regular 120 V outlet in Denver?
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 Denver's grid?
Yes. Denver's grid (WECC Rockies) is 35% dirtier than the US average, but a Silverado EV Trail Boss charged on it still makes 49% less CO₂ than a gas Silverado.
