Questions Salt Lake City drivers ask
How far can a Prologue go in a Salt Lake City winter?
About 226 miles on a typical January day (31°F) and about the same in the coldest week of the year (around December 27, 31°F on average), estimated from real EV drives at those temperatures. That's 17% below its 273-mile rating, mostly from heating the cabin and the battery. Salt Lake City averages 41 days a year below freezing.
How much does it cost to charge a Prologue in Salt Lake City?
About $59 a month at home for 38 miles a day, at Utah's average home electricity rate of 13.1¢/kWh: about 5.1¢ a mile. An average standard SUV on the Rocky Mountains's average gas ($4.47 a gallon) costs about $304 a month for the same driving.
Can I charge a Prologue on a regular 120 V outlet in Salt Lake City?
At 38 miles a day, most of the year: a 120 V outlet adds about 41 miles in 12 hours on an average day, but about 35 in the coldest week, so it can fall a little behind then. A 240 V outlet fills it from 10% in about 9 hours.
Is it greener to drive electric on Salt Lake City's grid?
Yes, more than most places. Salt Lake City's grid (WECC Northwest) is 18% cleaner than the US average, so a Prologue charged on it makes 79% less CO₂ than an average standard SUV.
