2026 Chevrolet Silverado EV Trail Boss in Honolulu, HI

Winter range, charging cost and how far it goes, worked out for Honolulu's weather, grid and prices.

Winter barely touches range in Honolulu: at a typical January's 74°F, a Silverado EV Trail Boss gets an estimated 427 miles on a charge, 13% under its 493-mile rating, but about what it gets all year. Power is pricey in Hawaii (47.2¢/kWh), so charging at home costs about $310 a month for 38 miles a day, still less than the $331 a gas Silverado costs on the West Coast's gas. Honolulu's grid (HICC Oahu) is 94% dirtier than the US average, but charging on it still makes 27% less CO₂ than gas.

Questions Honolulu drivers ask

How far can a Silverado EV Trail Boss go in a Honolulu winter?

Honolulu's winters are mild: about 427 miles on a typical January day (74°F) and about the same in the coldest week (around January 15, 74°F), estimated from real EV drives at those temperatures. That's within 13% of its 493-mile rating.

How much does it cost to charge a Silverado EV Trail Boss in Honolulu?

About $310 a month at home for 38 miles a day, at Hawaii's average home electricity rate of 47.2¢/kWh: about 26.8¢ a mile. A gas Silverado on the West Coast's average gas ($4.87 a gallon) costs about $331 a month for the same driving.

Can I charge a Silverado EV Trail Boss on a regular 120 V outlet in Honolulu?

Not at 38 miles a day: a 120 V outlet adds only about 27 miles in 12 hours on an average day (27 in the coldest week). Plan on 240 V, which fills it from 10% in about 12 hours.

Is it greener to drive electric on Honolulu's grid?

Yes. Honolulu's grid (HICC Oahu) is 94% dirtier than the US average, but a Silverado EV Trail Boss charged on it still makes 27% less CO₂ than a gas Silverado.
