Winter range, charging cost and how far it goes, worked out for Raleigh's weather, grid and prices.
Winter barely touches range in Raleigh: at a typical January's 42°F, a Sierra EV gets an estimated 365 miles on a charge, within 7% of its 390-mile rating. Charging at home at North Carolina's average rate (15.2¢/kWh) costs about $97 a month for 38 miles a day, against $279 for a gas Sierra on the Lower Atlantic's gas.

Questions Raleigh drivers ask
How far can a Sierra EV go in a Raleigh winter?
Raleigh's winters are mild: about 365 miles on a typical January day (42°F) and about the same in the coldest week (around January 10, 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 Raleigh?
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 Raleigh?
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 Raleigh's grid?
Yes, more than most places. Raleigh's grid (SERC Virginia/Carolina) is 23% cleaner than the US average, so a Sierra EV charged on it makes 73% less CO₂ than a gas Sierra.
