Why this number

Charging a 2026 Honda Prologue costs about $17.05 for a full charge (~100 kWh) at the US average rate of 17¢/kWh — roughly $5.78 per 100 miles, or $694 a year at 12,000 miles. The Prologue uses 34.0 kWh/100 mi on the EPA combined cycle. The Prologue’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The Honda Prologue (EPA data for the 2026 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 34.0 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 Prologue at about $5.78 per 100 miles — 5.78¢ a mile. That lands mid-pack: 33th of the 67 current models tracked here. Nothing about the running cost of the Prologue will surprise you in either direction, which for a SUV at 34.0 kWh/100 mi is a reasonable outcome.

What a Prologue costs to charge at every rate

The same Prologue costs $4.20 per 100 miles at Idaho’s 12.35¢ and $17.92 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the Prologue: EPA’s 34.0 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 Prologue’s 5.78¢ 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 Prologue’s math in full — both formulas, and the electricity rate at which the advantage disappears.

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

EPA combined range is about 295 miles. Multiplying that by the car’s efficiency gives roughly 100 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 Prologue on a public fast charger

On a public fast charger at about 48¢/kWh the Prologue costs $16.32 per 100 miles against $5.78 at home — 2.8× — or roughly $1,958 a year instead of $694 if it never sees a home outlet. Why a session costs more than the posted price for a Prologue (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 Prologue’s $694 flat-rate figure.

The Prologue in cold weather

A hard winter lifts the Prologue from 34.0 to roughly 44.2 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $7.51 per 100 miles instead of $5.78 and an effective range nearer 227 miles than 295. The mechanics behind the Prologue’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the Prologue’s $694 annual figure above already averages the seasons.

Where the Prologue sits against other EVs

Its nearest neighbors on efficiency are the Volvo EX40 (33.8 kWh/100 mi) and the Ford Mustang Mach-E (34.3 kWh/100 mi). The Prologue at 34.0 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 SUV like the Prologue is the fixed requirement, the cheapest SUV to run tracked here is the Tesla Model Y at $549 a year — $145 less than the Prologue.

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

The EPA rates 3 configurations of the 2026 Prologue, and they are not close: 32.5 kWh/100 mi for the most efficient, 35.3 for the least, a 9% spread. At 12,000 miles that is about $57 a year between the cheapest and most expensive version of the same Prologue. Bigger wheels, all-wheel drive and performance tunes are usually what separates them — worth knowing before you tick the options box.

The tax question for the Prologue, answered plainly

Nothing about the Prologue 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 Prologue: 34.0 kWh/100 mi ÷ 100 × 17¢ = $5.78 per 100 miles; 295 mi × 34.0 ÷ 100 = 100 kWh, × $0.17 = $17.05 per full charge; $5.78 × 12,000 ÷ 100 = $694 a year. The Prologue’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
