Questions Winston-Salem drivers ask
How far can a Sierra EV go in a Winston-Salem winter?
Winston-Salem's winters are mild: about 357 miles on a typical January day (40°F) and about the same in the coldest week (around January 11, 39°F), estimated from real EV drives at those temperatures. That's within 9% of its 390-mile rating.

About $97 a month at home for 38 miles a day, at North Carolina's average home electricity rate of 15.2¢/kWh: about 8.4¢ a mile. A gas Sierra on the Lower Atlantic's average gas ($3.86 a gallon) costs about $279 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Winston-Salem?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (27 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Winston-Salem's grid?
