40 to 60 kWh Battery Upgrade

The MS40 was discontinued in early 2013 before shipping due to low demand.  Tesla elected to supply all committed MS40 pre-orders with an MS60 that was software limited to act like a MS40. Those owners can enable the full use of the battery for a $10,000 one-time charge.  This upgrade is done in software and does not require a service visit.  Call ownership if you wish to activate this option. Supercharging is not available on the MS40, but after the upgrade to be a MS60, you can also enable Supercharging for $2500.

    Has anyone upgraded? Seems like tesla would discount the upgrade at this point.

      I know a number of owners have upgraded. I don’t expect Tesla will lower the cost, partly because there are so few to deal with, and partly to avoid seeming unfair to those that paid for a S60. In some ways, S40 owners got a great deal – a battery that will likely last longer than any S60/85 since it will not allow it to go to the limits where some battery degradation may occur.
