The difference in weight between the 25 and 40 KWH pack is about the same as adding a passenger. Not likely to make a big difference in efficiency. The 100KWH pack on the other hand is bound to make some difference depending on how much rolling resistance changes. The dominant factor though is still likely to be wind resistance which won’t change with increased weight.
