Wyoming home charging cost for the 2026 Ford Mustang Mach-E Rally

A 2026 Ford Mustang Mach-E Rally draws 40.2 kWh per 100 miles per the EPA; at Wyoming's 13.88¢/kWh residential rate that's $5.57 per 100 miles charged at home, versus $16.02 for a 25.5-mpg gas car covering the same distance. Charging at home costs a fraction of what gas would here: 65.2% less than gas per mile, here specifically.

What a year of driving costs

At fueleconomy.gov's default of 15,000 annual miles, the 2026 Ford Mustang Mach-E Rally costs roughly $836 a year to charge at home in Wyoming, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,567 a year.

What one full charge costs

Covering the 2026 Ford Mustang Mach-E Rally's EPA-rated 255-mile range takes about 102.4 kWh, which costs about $14.21 at Wyoming's residential rate — figured from the EPA's own combined range and consumption numbers, not the pack's nameplate capacity.

Where this ranks

This combination ranks 7,370 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Ford Mustang Mach-E Rally alone ranks 271 of 400 models for efficiency; Wyoming alone ranks 12 of 51 states for electricity price.

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.
