Why this number

Charging a 2026 GMC Sierra EV costs about $31.00 for a full charge (~182 kWh) at the US average rate of 17¢/kWh — roughly $8.64 per 100 miles, or $1,036 a year at 12,000 miles. The Sierra EV uses 50.8 kWh/100 mi on the EPA combined cycle. The Sierra EV’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The GMC Sierra EV (EPA data for the 2026 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 50.8 kWh per 100 miles on the EPA combined cycle — the wall-outlet figure, so charging losses are already counted (look up your exact trim at fueleconomy.gov ). At the US average residential rate of 17¢/kWh that puts the Sierra EV at about $8.64 per 100 miles — 8.64¢ a mile. That is among the highest energy use of any EV sold — 66th of 67, counting up from the most efficient. Mass and aerodynamics dominate here, and the electricity bill reflects it. If running cost is your priority, this is the wrong end of the market.

What a Sierra EV costs to charge at every rate

The same Sierra EV costs $6.27 per 100 miles at Idaho’s 12.35¢ and $26.78 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the Sierra EV: EPA’s 50.8 kWh/100 mi is measured at the outlet, charger losses included; quick-fill your state above for your own figure.

That per-mile figure is the one to hold against gasoline: at 17¢/kWh the Sierra EV’s 8.64¢ a mile compares with about 13.6¢ for a 30-mpg gas car at $4.07 a gallon (EIA weekly, Aug 31, 2026). The EV vs gas cost guide works the Sierra EV’s math in full — both formulas, and the electricity rate at which the advantage disappears.

Range: what a “full charge” of the Sierra EV really means

EPA range across the lineup runs 283–410 miles, averaging 359. Multiplying that by the car’s efficiency gives roughly 182 kWh to refill a full range from empty, which is the honest way to think about a ‘full charge’ — battery capacity figures include a buffer you never actually use. That is a long range, and it means the per-charge cost below looks large simply because you are buying more miles at once — the per-mile figure is the one to compare.

The Sierra EV on a public fast charger

On a public fast charger at about 48¢/kWh the Sierra EV costs $24.38 per 100 miles against $8.64 at home — 2.8× — or roughly $2,926 a year instead of $1,036 if it never sees a home outlet. Why a session costs more than the posted price for a Sierra EV (10–80% charging curve, idle fees, per-minute billing) is explained once on the cost-to-charge hub ; the EV time-of-use calculator nets an overnight rate against the Sierra EV’s $1,036 flat-rate figure.

The Sierra EV in cold weather

A hard winter lifts the Sierra EV from 50.8 to roughly 66.0 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $11.23 per 100 miles instead of $8.64 and an effective range nearer 276 miles than 359. The mechanics behind the Sierra EV’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the Sierra EV’s $1,036 annual figure above already averages the seasons.

Where the Sierra EV sits against other EVs

Its nearest neighbors on efficiency are the Chevrolet Silverado EV (49.9 kWh/100 mi) and the GMC Hummer EV (67.8 kWh/100 mi). The Sierra EV at 50.8 kWh/100 mi sits against a set that runs from the Tesla Model Y at 26.9 kWh/100 mi, and the least efficient is the GMC Hummer EV at 67.8 — a spread that changes annual charging cost by $834 a year at 17¢/kWh and 12,000 miles. And if a pickup like the Sierra EV is the fixed requirement, the cheapest pickup to run tracked here is the Tesla Cybertruck at $879 a year — $157 less than the Sierra EV.

Trims: does the Sierra EV version you pick change the bill?

The EPA rates 3 configurations of the 2026 Sierra EV, from 49.5 to 52.4 kWh/100 mi. That is a narrow band — about $59 a year between the best and worst at 12,000 miles — so pick the trim you want and don’t agonise over the running cost.

How it compares inside the GMC range

The Sierra EV at 50.8 kWh/100 mi sits among 2 GMC EVs tracked here, running from 50.8 (Sierra EV) to 67.8 (Hummer EV). Also on this site: GMC Hummer EV .

The tax question for the Sierra EV, answered plainly

Nothing about the Sierra EV changes that: the rules are the same for every EV, and the full 2026 position — §30D, §25E, the ended §30C charger credit, state programs — is in the energy tax credit guide and on the cost-to-charge hub .

Frequently asked questions

How we calculated this

Worked for the Sierra EV: 50.8 kWh/100 mi ÷ 100 × 17¢ = $8.64 per 100 miles; 359 mi × 50.8 ÷ 100 = 182 kWh, × $0.17 = $31.00 per full charge; $8.64 × 12,000 ÷ 100 = $1,036 a year. The Sierra EV’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
