Questions Birmingham drivers ask
How far can a Sierra EV AT4 / Denali go in a Birmingham winter?
Birmingham's winters are mild: about 387 miles on a typical January day (45°F) and about the same in the coldest week (around January 13, 44°F), estimated from real EV drives at those temperatures. That's within 6% of its 410-mile rating.
How much does it cost to charge a Sierra EV AT4 / Denali in Birmingham?
About $94 a month at home for 38 miles a day, at Alabama's average home electricity rate of 16.4¢/kWh: about 8.1¢ a mile. A gas Sierra on the Gulf Coast's average gas ($3.78 a gallon) costs about $265 a month for the same driving.
Can I charge a Sierra EV AT4 / Denali on a regular 120 V outlet in Birmingham?
Not at 38 miles a day: a 120 V outlet adds only about 32 miles in 12 hours on an average day (30 in the coldest week). Plan on 240 V, which fills it from 10% in about 17 hours.
Is it greener to drive electric on Birmingham's grid?
Yes. Birmingham's grid (SERC South) is 10% dirtier than the US average, but a Sierra EV AT4 / Denali charged on it still makes 65% less CO₂ than a gas Sierra.
