Tesla's Master Plan Part 3 involves much more than vehicles and solar
Tesla
Tesla published its Master Plan Part 3, a comprehensive 41-page document outlining the company's ambitious strategy to create a sustainable global energy economy. Previously discussed at Tesla's Investor Day on March 1, the plan offers a detailed roadmap for end-use electrification, sustainable electricity generation, and storage.
The Three Main Components: Electricity Demand, Supply, and Material Feasibility
The Master Plan Part 3 consists of three main components: Electricity Demand, Electricity Supply, and Material Feasibility & Investment. The plan's primary objective is to forecast electricity demand in a fully electrified economy without fossil fuels, create a cost-effective electricity generation and storage portfolio, and determine the material needs and manufacturing investments required to enable such an economy.
Tesla's analysis concludes that a sustainable energy economy is technically feasible and would require less investment and material extraction than the current unsustainable energy system. The plan pushes the boundaries of thinking about material intensity, manufacturing capacity, and investment required for a worldwide transition across all energy sectors.
The document also provides insights into the current global energy supply, with 37% lost during extraction, refining, and transformation. Furthermore, 27% of energy is lost through inefficient end-uses like internal combustion engine vehicles and natural gas furnaces. Only 36% of the primary energy supply is actually utilized for productive work or heat in the economy.
Embracing the Potential of a Sustainable Global Energy Economy
Tesla's Master Plan Part 3 envisions a future where most upstream losses related to mining, refining, and burning fuels are eliminated, as well as downstream losses from non-electric end-uses. The plan outlines six steps to fully electrify the economy and eliminate fossil fuel use, including repowering the existing grid with renewables and switching to electric vehicles.
The analysis acknowledges that some industrial processes will require increased energy input and mining/refining activity (such as green hydrogen production and battery materials). Still, these drawbacks are outweighed by the benefits of an electrified, sustainable energy economy.
Despite being based on US energy data, the Master Plan Part 3 has broader implications for the global energy market, and it considers onshore/offshore wind, solar, existing nuclear, and hydro as sustainable electricity generation sources. However, it does not address carbon dioxide sequestration from past fossil fuel combustion, which could impact future energy demand.
Tesla's release of Master Plan Part 3 has set the stage for a groundbreaking shift in the energy landscape, challenging industries, governments, and individuals to reimagine the future of energy and embrace the potential of a sustainable global economy.

Tesla recently launched software update 2025.8.3, which included a bunch of “minor updates.” Nestled away in the release notes are a couple of interesting features - including some major changes to the Energy App.
We’re not quite sure we’d call these minor updates, so let’s take a bit of an exploration of the revitalized Energy App.
The Energy App has received some new categorization features in the Consumption tab. You can once again limit the graph by distance. As part of the 2024 Holiday Update, Tesla redesigned the consumption tab and brought it to the new Model S and Model X for the first time. However, with the redesign, Tesla removed the ability to choose the distance shown in the graph, instead providing a static display of the last 200 miles (300km).
The first part of the improved Energy App is bringing back this distance filter. You can now choose between showing the last 10, 100, or 200 miles (15, 150, or 300 km). This differs from the previous available distances of 5, 15 and 30 miles, but brings back the ability for the driver to choose a distance that may be more applicable to how they’re driving.
We’d love for Tesla to introduce custom distances by pinching and zooming the graph or simply add the ability to choose “This Drive Only” to the list of available distances.
Reset Energy App History
@EV3_Model3 on X
Sadly, the “Instant Range” button that was available in the Energy App before is still not available, but Tesla introduced a new feature that may be even better. You can now clear your driving history so that the graph only reflects your current driving style.
This is a little hidden, but if you tap the little info icon at the top near your average Wh/mi, you’ll now be presented with a dialog that lets you clear your history.
This could be useful if you’ve just come from some hard driving on a track or off-road, where energy consumption could be exaggerated. It could also be useful if you just started towing or a different type of driving that is drastically different from your current driving.
Other Changes
In addition, it looks like future predictions of the Energy app now take into account your driving history and apply that in addition to expected vehicle consumption, weather, altitude, and the multitude of other factors that your Tesla constantly takes into account while calculating your expected range.
While these are smaller improvements to the Energy app, they added some important functionality, as it helps users better understand their vehicle consumption and display data that is more applicable to the current driving style.
This is a great example of Tesla listening to its customers and bringing back features they had previously been removed. Check out the video below by akide on the updated Energy app in update 2025.8.3.
Sandy Munro once again had the opportunity to chat (video below) with Lars Moravy, Tesla’s Vice President of Vehicle Engineering, as well as Franz Von Holzhausen, Tesla’s Chief of Vehicle Design. This time, rather than focusing on the improvements to the refreshed Model Y and all the new engineering behind it, the focus was on Tesla’s autonomous ambitions.
In this case, the Cybercab and Robovan were the key highlights, with a distinct focus on the Cybercab. With that all said, let’s dig into all the fun new stuff. You can check out the entire video at the end of the article.
Cybercab Unboxed Process
The Cybercab will be the first of Tesla’s vehicles to use their new unboxed assembly process, which builds vehicles in parallel sections, and then brings them together all at once for final assembly. Traditionally, vehicles are assembled from the ground up, and sometimes even disassembled for parts of production to take place.
This innovative method involves using a big rear and front casting, brought together by a structural battery pack on the floor. The door rings are hot-stamped and laser-welded to form the side shell of the Cybercab, resulting in a very rigid structure that can also absorb crash impacts due to its unique manufacturing.
Paint-Free Panels
We’ve already talked about the Cybercab’s unique paint-free panels, but we’ve never heard until now exactly how Tesla intends to manufacture them. Tesla will inject colored PU plastic onto the backside of another plastic part (formed from various processes) and then ultrasonically weld that entire piece to an inner part.
That essentially combines multiple parts into one smooth piece that is easy to repair - because all you have to do is remove the entire panel - it just comes off as the interior fasteners are removed. There is no subframe holding it together - instead, the subframe is part of the panel.
The only area of the vehicle that will have any paint will be the hot-stamped door rings - which will be painted to improve corrosion resistance to protect the steel.
Aerodynamics
Aerodynamically, the Cybercab boasts the largest aero-cover-to-wheel ratio of any Tesla vehicle. This updated aero cover improves efficiency, even with the Cybercab’s relatively large tires—chosen to reduce rolling resistance. Interestingly, the impact of unsprung weight on efficiency is minimal compared to the benefits of improved rolling resistance and aerodynamics.
Another key to the aerodynamics is the teardrop shape of the Cybercab itself. With its low profile and smooth shape, it is extremely aerodynamically efficient. While neither Sandy nor Lars delved into drag coefficients, we expect it will likely be more efficient than the Model 3’s already fantastic Cd of 0.219.
Range and Battery Pack
Tesla currently has prototypes undergoing real-world testing at Giga Texas to evaluate range and efficiency. The goal is to ensure the vehicle can operate throughout an entire day in the city before returning to charge.
Tesla is targeting a battery pack under 50kWh, delivering close to 300 miles of real-world range—an impressive efficiency of around 166Wh/mi, even outperforming the Model 3’s lowest at 181Wh/mi.
When Does It Arrive?
So, with all that new knowledge - when does the Cybercab arrive? Well - the prototypes for the June Robotaxi network deployment in Austin are getting prepared now - but Tesla expects to begin production and sales sometime in the first half of 2026.
