Why this number

Charging a 2026 Audi Q4 e-tron costs about $14.71 for a full charge (~87 kWh) at the US average rate of 17¢/kWh — roughly $5.59 per 100 miles, or $671 a year at 12,000 miles. The Q4 e-tron uses 32.9 kWh/100 mi on the EPA combined cycle. The Q4 e-tron’s real cost scales with your own rate, from about 12¢ to over 50¢ across the US.

The Audi Q4 e-tron (EPA data for the 2026 model year, the newest the EPA lists; dollar figures use 2026 electricity rates) uses 32.9 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 Q4 e-tron at about $5.59 per 100 miles — 5.59¢ a mile. That is comfortably better than average — 23th 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 Q4 e-tron costs to charge at every rate

The same Q4 e-tron costs $4.06 per 100 miles at Idaho’s 12.35¢ and $17.34 at Hawaii’s 52.72¢ — a 4.3× spread that is entirely the rate:

Wall-side for the Q4 e-tron: EPA’s 32.9 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 Q4 e-tron’s 5.59¢ 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 Q4 e-tron’s math in full — both formulas, and the electricity rate at which the advantage disappears.

Range: what a “full charge” of the Q4 e-tron really means

EPA combined range is about 263 miles. Multiplying that by the car’s efficiency gives roughly 87 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 Q4 e-tron on a public fast charger

On a public fast charger at about 48¢/kWh the Q4 e-tron costs $15.79 per 100 miles against $5.59 at home — 2.8× — or roughly $1,895 a year instead of $671 if it never sees a home outlet. Why a session costs more than the posted price for a Q4 e-tron (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 Q4 e-tron’s $671 flat-rate figure.

The Q4 e-tron in cold weather

A hard winter lifts the Q4 e-tron from 32.9 to roughly 42.8 kWh/100 mi (the middle of the 20–40% rise real-world data shows), so $7.27 per 100 miles instead of $5.59 and an effective range nearer 202 miles than 263. The mechanics behind the Q4 e-tron’s winter penalty — cabin heat, battery chemistry, preconditioning from the wall — are on the hub ; the Q4 e-tron’s $671 annual figure above already averages the seasons.

Where the Q4 e-tron sits against other EVs

Its nearest neighbors on efficiency are the Tesla Model X (32.9 kWh/100 mi) and the Volvo EX30 (33.0 kWh/100 mi). The Q4 e-tron at 32.9 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 Q4 e-tron is the fixed requirement, the cheapest SUV to run tracked here is the Tesla Model Y at $549 a year — $122 less than the Q4 e-tron.

Trims: does the Q4 e-tron version you pick change the bill?

The EPA rates 3 configurations of the 2026 Q4 e-tron, and they are not close: 29.4 kWh/100 mi for the most efficient, 34.6 for the least, a 18% spread. At 12,000 miles that is about $106 a year between the cheapest and most expensive version of the same Q4 e-tron. 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 Audi range

The Q4 e-tron at 32.9 kWh/100 mi sits among 4 Audi EVs tracked here, running from 29.4 (A6 e-tron) to 44.4 (Q8 e-tron). Also on this site: Audi A6 e-tron , Audi Q6 e-tron , Audi Q8 e-tron .

The tax question for the Q4 e-tron, answered plainly

Nothing about the Q4 e-tron 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 Q4 e-tron: 32.9 kWh/100 mi ÷ 100 × 17¢ = $5.59 per 100 miles; 263 mi × 32.9 ÷ 100 = 87 kWh, × $0.17 = $14.71 per full charge; $5.59 × 12,000 ÷ 100 = $671 a year. The Q4 e-tron’s gasoline comparison is 12,000 ÷ 30 mpg × $4.07 = $1,628. EPA combined ratings, measured at the wall.
