Questions San Jose drivers ask
How far can a Sierra EV go in a San Jose winter?
San Jose's winters are mild: about 376 miles on a typical January day (51°F) and about the same in the coldest week (around December 19, 50°F), estimated from real EV drives at those temperatures. That's within 4% of its 390-mile rating.
How much does it cost to charge a Sierra EV in San Jose?
About $211 a month at home for 38 miles a day, at California's average home electricity rate of 33.6¢/kWh: about 18.2¢ a mile. A gas Sierra on California's average gas ($6.03 a gallon) costs about $436 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in San Jose?
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 10 hours.
Is it greener to drive electric on San Jose's grid?
Yes, more than most places. San Jose's grid (WECC California) is 44% cleaner than the US average, so a Sierra EV charged on it makes 81% less CO₂ than a gas Sierra.
