What charging actually costs here

Filling a GMC Sierra EV from empty in Rhode Island costs $59.32. The car draws 202.9 kWh from the wall for a full 410-mile charge, and Rhode Island residential electricity averages 29.23¢ per kWh. That works out at $14.47 per 100 miles, or $0.14 a mile.

Rhode Island is more expensive than average: 29.23¢ against a national mean of 19.42¢, which ranks it 46 of 51 for electricity price. The same car costs $26.61 to fill in Nevada and $107.00 in Hawaii — a 4.0× spread across the country for identical driving.

This is one of the few places where the sum does not favour electricity. At 29.23¢ per kWh, running the GMC Sierra EV costs $14.47 per 100 miles while a 30 mpg petrol car costs $13.62 — so over 12,000 miles you would spend about $102 more on electricity. Home solar or an off-peak tariff changes that quickly, but the flat residential rate does not.

How much does a GMC Sierra EV cost per mile in Rhode Island?

About $0.14 a mile, or $14.47 per 100 miles. Over 12,000 miles a year that is roughly $1,736 of electricity.

Is charging a GMC Sierra EV cheaper than petrol in Rhode Island?

Not at the flat residential rate. Electricity costs $14.47 per 100 miles here against $13.62 for a 30 mpg petrol car, so you would spend roughly $102 more a year. Rhode Island has the kind of electricity prices where an off-peak tariff or solar makes the difference.

How long does a full charge last?

The EPA rates the GMC Sierra EV at 410 miles combined. Cold weather, motorway speeds and a loaded car all reduce that; the EPA number is a standardised test, not a guarantee.

Does this include charging losses?

Yes. The EPA's 49.5 kWh/100 mi figure is measured at the wall socket, so the energy lost in the charger and cabling is already in the number. No extra efficiency factor is applied.
