Questions Boise drivers ask
How far can a LYRIQ go in a Boise winter?
About 263 miles on a typical January day (32°F) and about 258 in the coldest week of the year (around December 24, 31°F on average), estimated from real EV drives at those temperatures. That's 16–18% below its 314-mile rating, mostly from heating the cabin and the battery. Boise averages 33 days a year below freezing.
How much does it cost to charge a LYRIQ in Boise?
About $61 a month at home for 38 miles a day, at Idaho's average home electricity rate of 13.7¢/kWh: about 5.3¢ a mile. An average small SUV on the Rocky Mountains's average gas ($4.47 a gallon) costs about $199 a month for the same driving.
Can I charge a LYRIQ on a regular 120 V outlet in Boise?
At 38 miles a day, most of the year: a 120 V outlet adds about 45 miles in 12 hours on an average day, but about 34 in the coldest week, so it can fall a little behind then. A 240 V outlet fills it from 10% in about 6 hours.
Is it greener to drive electric on Boise's grid?
Yes, more than most places. Boise's grid (WECC Northwest) is 18% cleaner than the US average, so a LYRIQ charged on it makes 68% less CO₂ than an average small SUV.
