We did 337kms in 3hrs 40mins including a 10 minute coffee break (so average speed was 96km/h).
We used 58,9kWh of energy so that translates to about €8 of power at night time rates or €10 normal rate.
There is about 27% of the battery left although the pessimistic range estimator in the Model S says that is just 96kms in ideal circumstances. Should be more like 120kms.
Now we have 3 hours to walk eat and shop (there’s a shopping mall adjoining the hotel which is great). Nice to have rest with the family frankly.
