Questions Las Vegas drivers ask
How far can a Sierra EV go in a Las Vegas winter?
Las Vegas's winters are mild: about 373 miles on a typical January day (49°F) and about 370 in the coldest week (around December 18, 46°F), estimated from real EV drives at those temperatures. That's within 5% of its 390-mile rating. The harder season here is summer: about 361 miles in July, with the air conditioning on.
How much does it cost to charge a Sierra EV in Las Vegas?
About $82 a month at home for 38 miles a day, at Nevada's average home electricity rate of 12.8¢/kWh: about 7.1¢ a mile. A gas Sierra on the West Coast's average gas ($5.01 a gallon) costs about $362 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Las Vegas?
Not at 38 miles a day: a 120 V outlet adds only about 28 miles in 12 hours on an average day (28 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Las Vegas's grid?
Yes. Las Vegas's grid (WECC Southwest) is about the US average, and a Sierra EV charged on it makes 68% less CO₂ than a gas Sierra.
