2027 Audi A6 e-tron ultra: home charging cost in North Dakota

In North Dakota, home electricity runs 12.19¢/kWh — put a 2027 Audi A6 e-tron ultra's EPA-rated 26.5 kWh/100mi against that and 100 miles costs $3.23, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 79.9% less than gas per mile, here specifically.

Next step: home charger installation

The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.

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