Questions Indianapolis drivers ask
How far can a Sierra EV go in a Indianapolis winter?
About 298 miles on a typical January day (29°F) and about 295 in the coldest week of the year (around January 15, 28°F on average), estimated from real EV drives at those temperatures. That's 24% below its 390-mile rating, mostly from heating the cabin and the battery. Indianapolis averages 55 days a year below freezing.
How much does it cost to charge a Sierra EV in Indianapolis?
About $112 a month at home for 38 miles a day, at Indiana's average home electricity rate of 16.7¢/kWh: about 9.7¢ a mile. A gas Sierra on the Midwest's average gas ($4.14 a gallon) costs about $300 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Indianapolis?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (22 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Indianapolis's grid?
Yes. Indianapolis's grid (RFC West) is 19% dirtier than the US average, but a Sierra EV charged on it still makes 57% less CO₂ than a gas Sierra.
