This week the world noticed that Tesla officially dropped the “Motors” portion of its name, but we had no idea why. Now we may have a reason – Tesla has just unveiled its new master plan, which will see the automaker branch out from just producing electric cars. Tesla CEO Elon Musk has revealed that Tesla will soon start building heavy-duty trucks and buses, which will be unveiled as early as next year. In the “Master Plan Part Deux”, as Elon Musk described it on his website, he also outlines his plan for combining battery technology with solar infrastructure to move the world away from unsustainable fossil fuels.

Ten years ago, Elon Musk revealed his master plan for Tesla, which involved first creating a pricey low volume car, the Roadster, which would be followed by a cheaper medium volume car at a lower price, the Model S, ending with an affordable, high volume car, the upcoming Model 3. Ten years ago Tesla even had ambitions to enter the solar power segment, which was solved recently when Tesla announced plans to buy SolarCity. Now Elon Musk has revealed its second master plan in an article on the Tesla blog.

The new plan sees the expansion of Tesla’s current models, more expansion into the solar segment and even producing heavy-duty trucks, and buses fit for public transit. With the upcoming arrival of the Model 3, which will be followed by a compact SUV and even an electric pickup, Tesla feels that it will have an electric vehicle in every consumer segment that it needs. Tesla has no plans to build anything cheaper than the Model 3 and instead plans to focus its efforts on a completely different segment as it seeks to promote a sustainable future that is not reliant on fossil fuels. By next year Tesla plans to reveal its first heavy-duty truck and even a high-passenger bus. Tesla says that both vehicles are in the early development stages, but the Tesla Semi will deliver a substantial reduction in the cost of cargo transport, while increasing safety.

The Tesla bus will be able to hold more passengers than today’s buses, by eliminating the center aisle and putting seats where there are currently entryways. The bus will also be fully autonomous, which will be able to match the acceleration and braking of other vehicles, thus avoiding the inertial impedance to smooth traffic flow of traditional heavy buses.

Elon Musk also details his company’s plans to improve autonomous driving technology to allow for car sharing on a large scale. Here’s how he sums it up in the detailed blog post announcement:

So, in short, Master Plan, Part Deux is:

Create stunning solar roofs with seamlessly integrated battery storage Expand the electric vehicle product line to address all major segments Develop a self-driving capability that is 10X safer than manual via massive fleet learning Enable your car to make money for you when you aren’t using it
