Questions Seattle drivers ask
How far can a Silverado EV 3WT go in a Seattle winter?
Seattle's winters are mild: about 411 miles on a typical January day (42°F) and about the same in the coldest week (around December 19, 41°F), estimated from real EV drives at those temperatures. That's within 5% of its 393-mile rating.
How much does it cost to charge a Silverado EV 3WT in Seattle?
About $84 a month at home for 38 miles a day, at Washington's average home electricity rate of 14.7¢/kWh: about 7.3¢ a mile. A gas Silverado on Seattle's average gas ($5.53 a gallon) costs about $376 a month for the same driving.
Can I charge a Silverado EV 3WT on a regular 120 V outlet in Seattle?
Not at 38 miles a day: a 120 V outlet adds only about 32 miles in 12 hours on an average day (32 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Seattle's grid?
Yes, more than most places. Seattle's grid (WECC Northwest) is 18% cleaner than the US average, so a Silverado EV 3WT charged on it makes 73% less CO₂ than a gas Silverado.
