I, too, wish Tesla would re-consider their decision to abandon a 40kWh version of the Model S. Especially for the European markets where there is not quite such a call for high range capability. With a comprehensive SuperCharger network installed, 160 mile range would suit 99% of car journeys in the UK and probably most other European countries too. That said, if there is some technical reason why you can't SuperCharge the original design of 40kWh pack, then it wouldn't work anyway. I suspect, however, the original plan to not allow 40kWh S' to use the SuperChargers was more to do with marketing than physics.
Offering a 40kWh S in Europe would probably double their potential customer base - if it really was $10k cheaper. Like Rifleman, as things stand, I will be looking for a 'used' 60kWh S in 18 months or so. MW
