Why this number

Charging a 2025 Polestar 2 costs about $15.97 for a full charge (~94 kWh) at the US average rate of 17¢/kWh — roughly $5.64 per 100 miles, or $677 a year at 12,000 miles. The 2 uses 33.2 kWh/100 mi on the EPA combined cycle. The 2’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The Polestar 2 (EPA data for the 2025 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 33.2 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 2 at about $5.64 per 100 miles — 5.64¢ a mile. That is comfortably better than average — 27th most efficient of the 67 current models tracked here — and puts running costs in the range most buyers hope for when they switch.

What a 2 costs to charge at every rate

The same 2 costs $4.10 per 100 miles at Idaho’s 12.35¢ and $17.50 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the 2: EPA’s 33.2 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 2’s 5.64¢ 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 2’s math in full — both formulas, and the electricity rate at which the advantage disappears.

Range: what a “full charge” of the 2 really means

EPA range across the lineup runs 254–314 miles, averaging 283. Multiplying that by the car’s efficiency gives roughly 94 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.

The 2 on a public fast charger

On a public fast charger at about 48¢/kWh the 2 costs $15.94 per 100 miles against $5.64 at home — 2.8× — or roughly $1,912 a year instead of $677 if it never sees a home outlet. Why a session costs more than the posted price for a 2 (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 2’s $677 flat-rate figure.

The 2 in cold weather

A hard winter lifts the 2 from 33.2 to roughly 43.2 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $7.34 per 100 miles instead of $5.64 and an effective range nearer 218 miles than 283. The mechanics behind the 2’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the 2’s $677 annual figure above already averages the seasons.

Where the 2 sits against other EVs

Its nearest neighbors on efficiency are the Kia EV6 (33.2 kWh/100 mi) and the BMW i5 (33.3 kWh/100 mi). The 2 at 33.2 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.

Trims: does the 2 version you pick change the bill?

The EPA rates 5 configurations of the 2025 2, and they are not close: 29.6 kWh/100 mi for the most efficient, 36.9 for the least, a 25% spread. At 12,000 miles that is about $149 a year between the cheapest and most expensive version of the same 2. Bigger wheels, all-wheel drive and performance tunes are usually what separates them — worth knowing before you tick the options box.

How it compares inside the Polestar range

The 2 at 33.2 kWh/100 mi sits among 3 Polestar EVs tracked here, running from 33.2 (2) to 39.7 (4). Also on this site: Polestar 3 , Polestar 4 .

The tax question for the 2, answered plainly

Nothing about the 2 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 2: 33.2 kWh/100 mi ÷ 100 × 17¢ = $5.64 per 100 miles; 283 mi × 33.2 ÷ 100 = 94 kWh, × $0.17 = $15.97 per full charge; $5.64 × 12,000 ÷ 100 = $677 a year. The 2’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
