The mid-range Tesla Model S with SuperCharger is Tesla's sweet spot
The Tesla Model S electric car has an EPA certified driving range of 265 miles, when outfitted with an 85 kiloWatt-hour battery pack. To match the supersized battery pack, the Model S includes a fast charging system capable of a complete recharge in an hour when charged with the Tesla-proprietary SuperCharger. Until now the SuperCharger was standard equipment only for the 85 kiloWatt-hour Model S, and was listed as an option for the 60 kiloWatt-hour Model S, and completely unavailable for the 45 kiloWatt-hour model. It's recently been noticed that the Tesla Model S options page now lists the Supercharger as standard for the 60 kWh model.
It is the 60 kiloWatt-hour Model S with SuperCharger that should be the sweet spot in the Model S lineup. To see why, consider these factoids:
The 60 kWh Tesla Model S has not been officially rated by the EPA, but we can expect it to be certified for approximately a 187 mile driving range. There is a $10,000 price premium between the 85 kWh and 60 kWh versions of the Model S, for which you buy a 265 mile driving range versus a 187 mile driving range.
