In a blog posted late Wednesday entitled “Master Plan, Part Deux”, Tesla Motor’s CEO chief executive Elon Musk reveals the second part of his vision for the company’s contribution to a “sustainable energy economy.”

In the proposal, Musk outlines four objectives, namely:

  1. Integrate Energy Generation and Storage via the creation of “stunning solar roofs with seamlessly integrated battery storage”
  2. Expand to Cover the Major Forms of Terrestrial Transport by “expanding the electric vehicle product line to address all major segments”
  3. Autonomy through the development of a “self-driving capability that is 10X safer than manual via massive fleet learning”
  4. Sharing by enabling your car to “make money for you when you aren’t using it”

In order to fulfill these goals, Musk suggests that combining and scaling the Powerwall and SolarCity initiatives will be necessary and reveals that Tesla is currently developing a compact SUV, pickup truck, heavy-duty truck and a “high-passenger density” urban transport vehicle.

To achieve mandates for autonomy and sharing, Musk indicates that all Tesla vehicles will need to be self-driving with “fail-operational capability” for fault tolerance and provide owners with the ability to offset vehicle costs by making them available for use by others in exchange for a fee.
