Questions Chattanooga drivers ask
How far can a Silverado EV Trail Boss go in a Chattanooga winter?
Chattanooga's winters are mild: about 457 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 493-mile rating.
How much does it cost to charge a Silverado EV Trail Boss in Chattanooga?
About $85 a month at home for 38 miles a day, at Tennessee's average home electricity rate of 13.4¢/kWh: about 7.3¢ a mile. A gas Silverado on the Midwest's average gas ($4.27 a gallon) costs about $290 a month for the same driving.
Can I charge a Silverado EV Trail Boss on a regular 120 V outlet in Chattanooga?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (29 in the coldest week). Plan on 240 V, which fills it from 10% in about 12 hours.
Is it greener to drive electric on Chattanooga's grid?
Yes. Chattanooga's grid (SERC Tennessee Valley) is 17% dirtier than the US average, but a Silverado EV Trail Boss charged on it still makes 57% less CO₂ than a gas Silverado.
