In September 2025, Tesla released Master Plan Part 4 as a short, hopeful document (available at tesla.com and as PDF). It updates Tesla’s mission from “sustainable energy” to “accelerating the world’s transition to sustainable abundance.” The plan rests on five clear guiding principles, quoted directly from the official PDF:

1. “Growth is infinite” – progress does not require trade-offs.
2. “Innovation removes constraints” – every big leap in history broke a supposed limit.
3. “Technology solves tangible problems” – in energy (solar + batteries + AI), mobility (autonomous EVs), and labor (Optimus robots).
4. “Autonomy benefits all humanity” – safety and universal access come first.
5. “Greater access drives greater growth” – the cheaper and wider the technology spreads, the better life gets for everyone.

The heart of the plan is simple: combine Tesla’s cars, solar roofs, batteries, self-driving software, and Optimus humanoid robots so that energy, transport, and work become effectively unlimited and almost free. When boring or dangerous jobs are done by friendly robots and cars drive themselves safely, people are freed to create, learn, and enjoy life.Elon Musk has said the same in his own words:

• “The ultimate master plan of Tesla is to create sustainable abundance for all.” (X, March 21, 2025)
• “There will be universal high income… Sustainable abundance.” (X, August 24, 2025)
• “Working on the Tesla Master Plan 4. It will be epic.” (X, June 17, 2024)

The super short document ends gently: “The tools we are going to develop will help us build the kind of world that we’ve always dreamed of — a world of sustainable abundance.” That is the whole plan: five principles, three real-world solutions, and one kind promise — abundance for everyone, built step by step with Tesla’s products.
