2025 GMC Sierra EV in Tulsa, OK
Winter range, charging cost and how far it goes, worked out for Tulsa's weather, grid and prices.
Winter barely touches range in Tulsa: at a typical January's 39°F, a Sierra EV gets an estimated 350 miles on a charge, 10% under its 390-mile rating, but about what it gets all year. Charging at home at Oklahoma's average rate (14.3¢/kWh) costs about $92 a month for 38 miles a day, about a third of the $300 a gas Sierra costs on the Midwest's gas. Tulsa's grid (SPP South) is 14% dirtier than the US average, but charging on it still makes 60% 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 Tulsa drivers ask
How far can a Sierra EV go in a Tulsa winter?
Tulsa's winters are mild: about 350 miles on a typical January day (39°F) and about the same in the coldest week (around January 6, 38°F), estimated from real EV drives at those temperatures. That's within 11% of its 390-mile rating.
How much does it cost to charge a Sierra EV in Tulsa?
About $92 a month at home for 38 miles a day, at Oklahoma's average home electricity rate of 14.3¢/kWh: about 8.0¢ a mile. A gas Sierra on the Midwest's average gas ($4.14 a gallon) costs about $300 a month for the same driving.
Can I charge a Sierra EV on a regular 120 V outlet in Tulsa?
Not at 38 miles a day: a 120 V outlet adds only about 29 miles in 12 hours on an average day (26 in the coldest week). Plan on 240 V, which fills it from 10% in about 10 hours.
Is it greener to drive electric on Tulsa's grid?
Yes. Tulsa's grid (SPP South) is 14% dirtier than the US average, but a Sierra EV charged on it still makes 60% less CO₂ than a gas Sierra.
