Questions St. Louis drivers ask
How far can a Silverado EV Trail Boss go in a St. Louis winter?
About 390 miles on a typical January day (32°F) and about 387 in the coldest week of the year (around January 14, 32°F on average), estimated from real EV drives at those temperatures. That's 21–22% below its 493-mile rating, mostly from heating the cabin and the battery. St. Louis averages 13 days a year below freezing.
How much does it cost to charge a Silverado EV Trail Boss in St. Louis?
About $104 a month at home for 38 miles a day, at Missouri's average home electricity rate of 16.0¢/kWh: about 9.0¢ a mile. A gas Silverado on the Midwest's average gas ($4.27 a gallon) costs about $290 a month for the same driving.
Can I charge a Silverado EV Trail Boss on a regular 120 V outlet in St. Louis?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (25 in the coldest week). Plan on 240 V, which fills it from 10% in about 12 hours.
Is it greener to drive electric on St. Louis's grid?
Yes. St. Louis's grid (SERC Midwest) is 62% dirtier than the US average, but a Silverado EV Trail Boss charged on it still makes 40% less CO₂ than a gas Silverado.
