About the BMW i4 eDrive40 in New Hampshire
The BMW i4 eDrive40 carries a 81 kWh usable battery and achieves about 3.4 miles per kWh at the wheels under EPA-combined conditions. In New Hampshire, where residential electricity averages 27.24¢/kWh, that translates to roughly $8.90 per 100 miles — for comparison, a gasoline car at 30 MPG and $3.50/gallon costs $11.67 per 100 miles, so a BMW i4 eDrive40 owner in New Hampshire saves about $332/year on fuel relative to that baseline.
This estimate is for home Level 2 charging only. Public DC fast charging typically costs 2-3× the home rate; if you primarily fast-charge, your annual cost will be higher.
