Tesla has revealed more about how it builds the Cybercab at its Texas factory: separate lines assemble and test major vehicle sections before robots join them, with much of the wiring and interior already installed. Tesla says the approach avoids a conventional paint shop and could support output of 125,000 vehicles a year, but the company has not said when the line will reach that rate or how quickly it will deploy the cars.
Tesla has disclosed more about the Cybercab’s “unboxed” production process, in which factory teams build and test the front, rear, sides and floor separately before joining them near the end of assembly. The Texas line is designed to reduce the work done inside a nearly completed vehicle, and Tesla says it can produce 125,000 Cybercabs per year at full capacity; the company has not said when it expects to reach that rate.
In a video tour published by engineering firm Munro & Associates, Tesla engineering chief Lars Moravy and Cybercab lead Eric Earley described how the separate modules move through the factory. The sections arrive at an automated framing line with components such as wiring and hoses already installed. Robots position and join them, after which the assembled vehicle enters a final line of about 25 stations. Moravy said a Model Y line has roughly five to 10 times as many final-assembly stations.
The approach changes where work happens. The front module includes the drive unit, suspension and thermal hardware on a positioning pallet; Tesla says it contains roughly half the car’s parts and content. The front structure, with its dashboard already fitted, is lowered over those components. Other teams can work on side sections laid flat, install overhead parts at a comfortable height, and attach seats and carpet to the battery pack. Its top cover also serves as the cabin floor.
Tesla says the factory is about 78% automated, and that its process includes checks at multiple stages: components are tested before they become part of larger assemblies, which are tested again. Moravy said the front module reaches the joining stage with its computers connected and systems checked. The goal is to catch faults before components become difficult to reach inside the vehicle.
Why Modular Assembly Matters
Building accessible sections in parallel could reduce the need for workers or robots to reach into a partly completed car and may let Tesla place production stations closer together. Those are design aims described by the company, not proof that the method has already lowered costs or shortened production times at scale. Tesla’s reported 25 final-assembly stations offers a concrete point of comparison with the longer Model Y line, but it does not by itself establish total factory time or output per worker.
The exterior process also changes factory requirements. Cybercab’s plastic panels have color infused during molding, so Tesla says it does not need a conventional paint shop for them. That can remove a major production stage and its associated factory space. The choice matters for owners too: Tesla’s engineers said scratches can be repaired in a way similar to conventional paint, but the video does not provide repair costs, procedures or long-term durability results.
For readers, the practical question is whether this production design can support a reliable, affordable fleet as Tesla expands Cybercab deployment. The factory’s stated capacity is a company figure for full-rate production, not evidence that it is currently making that many vehicles or that demand and deployment will match the capacity.

From Car Body to Separate Modules
Conventional vehicle production typically assembles a body, paints it, and then adds mechanical systems, wiring and interior parts as the vehicle moves down a long assembly line. Tesla has discussed an alternative called “unboxed” manufacturing for several years. In the Munro video, Moravy said the idea took shape about six years ago, after the company struggled to automate existing vehicle designs and concluded that the design itself was limiting robot access.
Rather than finish a body early and install much of the vehicle inside it, Tesla’s Cybercab process builds and equips major sections on separate lines. The company says molded exterior panels avoid a conventional paint stage; the front and rear structural modules also skip electrocoating, while the steel side structures remain coated. Tesla said it considered films and other options before settling on the molded-color approach.
The Cybercab is not the only planned use of modular manufacturing. Ford is developing a similar approach for its Universal Electric Vehicle platform, which it calls an “assembly tree.” That comparison describes a shared production idea; it does not establish that the two companies’ factory designs or products are the same.
“The idea began about six years ago, when Tesla was stuck trying to automate existing designs and concluded the problem was the car.”
— Lars Moravy, Tesla engineering chief, in the Munro & Associates video
Production Rate and Repair Questions
Tesla has not disclosed the Cybercab line’s current production rate, how many vehicles it has built, or when it expects the factory to reach the stated 125,000-a-year capacity. The company has said the factory does not operate every day because it can build Cybercabs faster than it is deploying them, but the video does not quantify either production or rollout. It is not clear how much this reflects factory capacity, deployment plans or other constraints.
Other details also remain open. The source does not give independent measurements of cost savings, cycle time, defect rates or repair expenses. Tesla says scratches on the molded-color exterior can be repaired similarly to those on painted cars, but the specific repair methods and their costs are not detailed. Claims about automation and process efficiency should be understood as descriptions from Tesla, not independently verified production results.
Scaling the Cybercab Line
The next test is whether Tesla increases production and deployment enough to use more of the factory’s stated capacity. Tesla CEO Elon Musk set a goal of 5 million annual vehicle deliveries by 2030 on the company’s last earnings call, according to the source report. That is a company target, not a confirmed forecast, and the report does not specify how many of those deliveries would be Cybercabs.
Future updates that would clarify the picture include Tesla’s reported Cybercab output, factory operating schedule and deployment pace, as well as evidence on repairability and production performance over time. Until the company provides those figures, the 125,000-vehicle capacity should be treated as a stated full-rate ceiling rather than a current result.
Key Questions
What does Tesla mean by “unboxed” production?
It means building and equipping the front, rear, sides and floor separately, then bringing those sections together on an automated framing line. Much of the wiring and interior work is done before the modules are joined.
How many Cybercabs can the factory make?
Tesla says the line can produce 125,000 vehicles per year at full capacity. The company has not disclosed its current output or when it expects to reach that rate.
Why does the Cybercab not use a conventional paint shop?
Tesla says the exterior panels have color infused during molding, removing the need to paint those panels in a conventional paint shop. The steel side structures remain coated, according to the source report.
Does the new process mean Cybercabs are cheaper to repair?
That has not been established. Tesla engineers said scratches can be repaired similarly to conventional paint, but the available details do not specify repair procedures or costs.
