2027 Audi RS e-tron GT Performance: home charging cost in Michigan

In Michigan, home electricity runs 21.14¢/kWh — put a 2027 Audi RS e-tron GT Performance's EPA-rated 40.2 kWh/100mi against that and 100 miles costs $8.49, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home is much cheaper than gas here: 47% less than gas per mile, here specifically.

What a year of driving costs

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.
