Questions Knoxville drivers ask
How far can a Silverado EV Trail Boss go in a Knoxville winter?
Knoxville's winters are mild: about 443 miles on a typical January day (39°F) and about 440 in the coldest week (around January 10, 39°F), estimated from real EV drives at those temperatures. That's within 11% of its 493-mile rating.

About $85 a month at home for 38 miles a day, at Tennessee's average home electricity rate of 13.4¢/kWh: about 7.4¢ 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 Knoxville?
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 12 hours.
Is it greener to drive electric on Knoxville's grid?
Yes. Knoxville'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.
