2027 Subaru Solterra 20 AWD: home charging cost in Colorado

In Colorado, home electricity runs 16.65¢/kWh — put a 2027 Subaru Solterra 20 AWD's EPA-rated 28.9 kWh/100mi against that and 100 miles costs $4.82, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 69.9% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

Driving 15,000 miles a year — fueleconomy.gov's own default assumption — a 2027 Subaru Solterra 20 AWD charged at home in Colorado costs about $722/year in electricity, against about $2,403/year for the gas-car comparison. That's a savings of about $1,681 a year.

What one full charge costs

A 2027 Subaru Solterra 20 AWD needs roughly 80.4 kWh to reach its EPA-rated 278-mile range, which runs about $13.39 at 16.65¢/kWh in Colorado.

How this compares nationally

This combination ranks 3,679 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Subaru Solterra 20 AWD alone ranks 35 of 400 models for efficiency; Colorado alone ranks 30 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.

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