Charging a 2027 Audi A6 e-tron at home in Maine

In Maine, home electricity runs 29.67¢/kWh — put a 2027 Audi A6 e-tron's EPA-rated 30.3 kWh/100mi against that and 100 miles costs $9, versus $16.02 for a gas car averaging 25.5 mpg. That works out to 43.8% cheaper per mile than gasoline in Maine — charging at home is much cheaper than gas here.

What a year of driving costs

Maine owners putting 15,000 annual miles on a 2027 Audi A6 e-tron spend about $1,350 on home electricity, compared to about $2,403 a gas-car equivalent would spend on fuel. Call it about $1,053 saved annually, at this mileage.

What one full charge costs

At Maine's rate, fully covering this 2027 Audi A6 e-tron's 348-mile EPA range costs about $31.33 (105.6 kWh) — the energy the EPA test actually used, not the battery's rated size.

Next step: home charger installation

Everything above is the per-mile and per-year cost once a home charger exists — getting one installed is a separate electrical job whose price depends on your panel and wiring, not the state average used here.

Ask a licensed Maine electrician to quote the install before this math becomes a real decision.
