Questions Sacramento drivers ask
How far can a Sierra EV AT4 / Denali go in a Sacramento winter?
Sacramento's winters are mild: about 393 miles on a typical January day (49°F) and about the same in the coldest week (around December 24, 48°F), estimated from real EV drives at those temperatures. That's within 5% of its 410-mile rating.
How much does it cost to charge a Sierra EV AT4 / Denali in Sacramento?
About $192 a month at home for 38 miles a day, at California's average home electricity rate of 33.6¢/kWh: about 16.6¢ a mile. A gas Sierra on California's average gas ($6.03 a gallon) costs about $423 a month for the same driving.
Can I charge a Sierra EV AT4 / Denali on a regular 120 V outlet in Sacramento?
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 Sacramento's grid?
Yes, more than most places. Sacramento's grid (WECC California) is 44% cleaner than the US average, so a Sierra EV AT4 / Denali charged on it makes 82% less CO₂ than a gas Sierra.
