Questions Jacksonville drivers ask
How far can a Sierra EV go in a Jacksonville winter?

About $96 a month at home for 38 miles a day, at Florida's average home electricity rate of 15.0¢/kWh: about 8.3¢ a mile. A gas Sierra on Florida's average gas ($3.98 a gallon) costs about $288 a month for the same driving.
