Questions Chattanooga drivers ask
How far can an Equinox EV go in a Chattanooga winter?
Chattanooga's winters are mild: about 287 miles on a typical January day (42°F) and about the same in the coldest week (around January 11, 41°F), estimated from real EV drives at those temperatures. That's within 7% of its 307-mile rating.

About $52 a month at home for 38 miles a day, at Tennessee's average home electricity rate of 13.7¢/kWh: about 4.5¢ a mile. A gas Equinox on the Midwest's average gas ($4.14 a gallon) costs about $184 a month for the same driving.
Can I charge an Equinox EV on a regular 120 V outlet in Chattanooga?
At 38 miles a day, yes, all year: a 120 V outlet adds about 45 miles in 12 hours even in Chattanooga's coldest week, and about 49 on an average day.
