Questions Fort Wayne drivers ask
How far can a Sierra EV AT4 / Denali go in a Fort Wayne winter?
About 325 miles on a typical January day (26°F) and about 322 in the coldest week of the year (around January 19, 25°F on average), estimated from real EV drives at those temperatures. That's 21% below its 410-mile rating, mostly from heating the cabin and the battery. Fort Wayne averages 76 days a year below freezing.
How much does it cost to charge a Sierra EV AT4 / Denali in Fort Wayne?
About $102 a month at home for 38 miles a day, at Indiana's average home electricity rate of 16.7¢/kWh: about 8.8¢ a mile. A gas Sierra on the Midwest's average gas ($4.14 a gallon) costs about $291 a month for the same driving.
Can I charge a Sierra EV AT4 / Denali on a regular 120 V outlet in Fort Wayne?
Not at 38 miles a day: a 120 V outlet adds only about 30 miles in 12 hours on an average day (25 in the coldest week). Plan on 240 V, which fills it from 10% in about 17 hours.
Is it greener to drive electric on Fort Wayne's grid?
Yes. Fort Wayne's grid (RFC West) is 19% dirtier than the US average, but a Sierra EV AT4 / Denali charged on it still makes 59% less CO₂ than a gas Sierra.
