Overall I average ~3.2mi/kWh on my Mach E. The charger that came with the car has a 120v 12A mode. That's ~1.4kW. Add some charging losses, at least 1.2kW prob

Overall I average ~3.2mi/kWh on my Mach E. The charger that came with the car has a 120v 12A mode. That's ~1.4kW. Add some charging losses, at least 1.2kW probably makes it into the battery. 1.2 * 3.2 > 1.5. Even a Lightning averages about 2mi/kWh. The Mach E isn't even that impressive in efficiency.
