Questions Memphis drivers ask
How far can a Sierra EV go in a Memphis winter?
Memphis's winters are mild: about 365 miles on a typical January day (42°F) and about the same in the coldest week (around January 9, 42°F), estimated from real EV drives at those temperatures. That's within 7% of its 390-mile rating.
How much does it cost to charge a Sierra EV in Memphis?
About $88 a month at home for 38 miles a day, at Tennessee's average home electricity rate of 13.7¢/kWh: about 7.6¢ 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 Memphis?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (28 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Memphis's grid?
Yes. Memphis's grid (SERC Tennessee Valley) is 17% dirtier than the US average, but a Sierra EV charged on it still makes 59% less CO₂ than a gas Sierra.
