Just one data point but I thought I'd try an experiment. I have the 18 inch tires with the aero hub caps removed.
I initialized charging using a gen 1 mobile unit on my 240 V 50 amp breaker circuit.
The Model 3 display read as follows:
76% battery remaining (237 miles), 40 amps, 241VAC, so initial calculated power being delivered is 9.64 kW
Stopped charging after exactly one hour and the actual energy delivered from my house meter was 9.35 kWh
The model 3 display now reads:
88% battery remaining (274 miles)
I then drove the car in town and highway over a two day period (more than 48 hours) 32.2 miles.
The model 3 display now reads:
77% battery remaining (237 miles) for 32.2 miles and 222 Wh/mile (this is an average)
To be a little more accurate I should have driven the car until the display showed 76% or 237 miles but there are many other inaccuracies in this experiment anyway.
During the one hour charge time I (remotely) monitored the actual power usage at my house meter.
The vampire drain of my house (air conditioner off but refrigerator may have cycled, TV vampire drain, etc) is included. The trip milage shown is over two days and includes both highway and around town usage.
90 degree Texas weather, 74 degree cabin during drives. Model 3 vampire drain for more than 48 hours is included.
Energy used by car over more than 48 hours and 32.2 miles is (32.2miles x 222 Wh/mile)= 7.148 kWh (7kWh display) Energy delivered to the car was 9.35 kWh
Actual watt hours per mile including car vampire drain for two days is: 290 Wh/mile or 3.34 miles/kWh
