2025 GMC Sierra EV in Worcester, MA
Winter range, charging cost and how far it goes, worked out for Worcester's weather, grid and prices.
In a typical Worcester January (25°F), a Sierra EV gets an estimated 277 miles on a charge, 29% less than its 390-mile rating, and about 274 miles in the coldest week of the year (around January 19, when it averages 24°F). By May it's back to about 384. Power is pricey in Massachusetts (30.5¢/kWh), so charging at home costs about $209 a month for 38 miles a day, still less than the $304 a gas Sierra costs on Massachusetts's gas. And Worcester's grid (NPCC New England), 30% cleaner than the US average, makes it 74% less CO₂ than gas.
Partly estimated. 2 of 5 temperature bands are from 116 real drives of this model; the rest come from 1,548 real drives in EVs at each temperature (and Recurrent's winter study below freezing), applied to its 390-mile rating. Each band switches to its own drives once it has 20 from 3 drivers.

Questions Worcester drivers ask
How far can a Sierra EV go in a Worcester winter?
About 277 miles on a typical January day (25°F) and about 274 in the coldest week of the year (around January 19, 24°F on average), estimated from real EV drives at those temperatures. That's 29–30% below its 390-mile rating, mostly from heating the cabin and the battery. Worcester averages 87 days a year below freezing.
How much does it cost to charge a Sierra EV in Worcester?
About $209 a month at home for 38 miles a day, at Massachusetts's average home electricity rate of 30.5¢/kWh: about 18.0¢ a mile. A gas Sierra on Massachusetts's average gas ($4.20 a gallon) costs about $304 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Worcester?
Not at 38 miles a day: a 120 V outlet adds only about 28 miles in 12 hours on an average day (21 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Worcester's grid?
Yes, more than most places. Worcester's grid (NPCC New England) is 30% cleaner than the US average, so a Sierra EV charged on it makes 74% less CO₂ than a gas Sierra.
