Is the food at motorway services really that good316wh per Mile. 2021, M3P
Over 32k miles. 95% of that will be motorway dining.
Mine is about the same using Ovo anytime, The 7.58 pence includes supercharging on long trips, etc.Where we do differ is my car is running around 2.2 pence/mile using Octopus IGO @ 7.5p/kwh
Well, my MYLR has sentry mode always on, except at home, so sadly your metric would affect people like me negatively due to the high consumption when parked. While I agree it's part of the total cost of ownership, it's still a choice, and that shouldn't could towards drivetrain efficiency.I think the most important measure of efficiency is when you take the total of kwh's supplied to the car ÷ by the number of miles travelled.
In my case, with a SR+, TeslaFi says I have added 7,189 kwh to the battery whereas Scan my Tesla says 7,238 kWh added to the battery. I will take an average of 7,200 kWh added to the battery. The majority of the kwh's added where done using a 7 kWh charger. TeslaFi says that it has an efficiency of 93.93 %, meaning I have supplied 7,200kWh ÷ 0.939 = 7,667 kWh's of energy.
The car has done 24,383 miles giving an average on 314.47 Wh/mi or 3.18 miles/kWh.
Using the figure of 7,667 kWh's x 0.075 kWh gives the total electricity running cost of £575 to drive 24,383 or 2.35 pence/mile
I would like to see this calculation made for other Tesla's and also other makes of BEV cars...
Data from SmT below, shows 5,913 kWh used and this ÷ 24,383 = 242 kWh/mi whereas my car is showing 241 kWh/mi

Using the total supplied energy of 3.18 miles/kWh and the fact that petrol has 43.96 kwh/UK gallon, the true MPG (with losses) can be found to be ~140 MPGe.
Thoughts anybody??
