Idaho home charging cost for the 2027 Mercedes-Benz CLA350 4matic with EQ Tech

In Idaho, home electricity runs 12.8¢/kWh — put a 2027 Mercedes-Benz CLA350 4matic with EQ Tech's EPA-rated 29 kWh/100mi against that and 100 miles costs $3.71, versus $16.02 for a gas car averaging 25.5 mpg. Charging at home costs a fraction of what gas would here: 76.8% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year

At fueleconomy.gov's default of 15,000 annual miles, the 2027 Mercedes-Benz CLA350 4matic with EQ Tech costs roughly $557 a year to charge at home in Idaho, against roughly $2,403 a year for an equivalent gas car. That's a savings of about $1,846 a year.

What one full charge costs

Covering the 2027 Mercedes-Benz CLA350 4matic with EQ Tech's EPA-rated 312-mile range takes about 90.5 kWh, which costs about $11.58 at Idaho'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 406 of 20,400 state/model pairs for cost savings against gas (1 is cheapest). The Mercedes-Benz CLA350 4matic with EQ Tech alone ranks 40 of 400 models for efficiency; Idaho alone ranks 3 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.
