Slate Reality Check · Boston, MA
Slate truck in Boston, MA
Winter range, charging cost and how far it goes, worked out for Boston's weather, grid and prices.
Boston's winters are cool rather than cold: on a typical January day (30°F) a Slate gets an estimated 166 miles, 19% under its 205-mile rating, about the same as in the coldest week (around January 19, when it averages 29°F). By May it's back to about 203. Power is pricey in Massachusetts (30.5¢/kWh), so charging at home costs about $116 a month for 38 miles a day, still less than the $189 a gas Ford Maverick costs on Boston's gas. On the US average grid it makes 67% less CO₂ than gas.
Estimated. Almost no one's driving a Slate yet, so these come from 1,548 real drives in other EVs at each temperature (and Recurrent's winter study below freezing), applied to the Slate's rating. They switch to real Slate drives as owners log them.
