2026 Mercedes-Benz EQS 450 Plus: home charging cost in Louisiana

A 2026 Mercedes-Benz EQS 450 Plus draws 34 kWh per 100 miles per the EPA; at Louisiana's 13.51¢/kWh residential rate that's $4.6 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: 71.3% less than gas per mile, here specifically.

Annual cost, at 15 thousands miles a year
