Questions Des Moines drivers ask
How far can a Silverado EV Trail Boss go in a Des Moines winter?
About 316 miles on a typical January day (22°F) and about 313 in the coldest week of the year (around January 15, 22°F on average), estimated from real EV drives at those temperatures. That's 36–37% below its 493-mile rating, mostly from heating the cabin and the battery. Des Moines averages 87 days a year below freezing.
How much does it cost to charge a Silverado EV Trail Boss in Des Moines?
About $117 a month at home for 38 miles a day, at Iowa's average home electricity rate of 17.1¢/kWh: about 10.1¢ 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 Des Moines?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (20 in the coldest week). Plan on 240 V, which fills it from 10% in about 12 hours.
Is it greener to drive electric on Des Moines's grid?
Yes. Des Moines's grid (MRO West) is 20% dirtier than the US average, but a Silverado EV Trail Boss charged on it still makes 53% less CO₂ than a gas Silverado.
