Questions Madison drivers ask
How far can a Silverado EV 4WT go in a Madison winter?
About 306 miles on a typical January day (19°F) and about 301 in the coldest week of the year (around January 18, 19°F on average), estimated from real EV drives at those temperatures. That's 32–33% below its 450-mile rating, mostly from heating the cabin and the battery. Madison averages 103 days a year below freezing.
How much does it cost to charge a Silverado EV 4WT in Madison?
About $131 a month at home for 38 miles a day, at Wisconsin's average home electricity rate of 19.1¢/kWh: about 11.4¢ a mile. A gas Silverado on the Midwest's average gas ($4.14 a gallon) costs about $282 a month for the same driving.
Can I charge a Silverado EV 4WT on a regular 120 V outlet in Madison?
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 11 hours.
Is it greener to drive electric on Madison's grid?
Yes. Madison's grid (MRO East) is 82% dirtier than the US average, but a Silverado EV 4WT charged on it still makes 28% less CO₂ than a gas Silverado.
