Tesla is using an “unboxed” process to build the Cybercab: separate lines assemble and test the vehicle’s main sections, which are then joined with much of their wiring and interior already installed. Tesla says the approach reduces factory steps and enables a line rated for 125,000 vehicles a year, though the company’s current production and deployment pace remains unclear.
Tesla is building its Cybercab by assembling the front, rear, sides and floor as separate modules, then joining them late in production, according to a factory-tour video featuring Tesla engineering leaders. The process, which Tesla calls “unboxed,” is designed to move wiring, interior installation and other work off the conventional final assembly line and could change how much factory space and labor the vehicle requires.
In the video, Tesla engineering chief Lars Moravy and Cybercab lead Eric Earley describe a production system that differs from the usual sequence of building a vehicle body, painting it, and installing components as it moves down one long assembly line. Tesla instead prepares the major sections on separate lines. Those sections arrive at an automated framing line with many components—including wiring and hoses—already fitted, and robots position and join them.
The front module carries roughly half the vehicle’s parts and content, according to Tesla. Its drive unit, suspension and thermal hardware are arranged on a positioning pallet, and the front structure, with the dashboard already installed, is lowered over them. Workers can build the side sections flat and fit overhead parts at a more accessible height. Seats and carpet are attached to the battery pack, whose upper cover also serves as the cabin floor.
After the modules are joined, the Cybercab moves through a final assembly line of about 25 stations. Moravy compared that with roughly five to 10 times as many stations for the Model Y. The wheels are installed at the second-to-last station; near the end, the vehicle rolls off the line on its wheels. Tesla says the line is about 78% automated, though that figure does not by itself describe how many workers are involved or how the automation rate is measured.
The production process also changes how the exterior is finished. Cybercab’s plastic panels are molded with color in the material, avoiding a traditional paint shop. Tesla’s engineers said the front and rear structural modules also skip electrocoating, while the steel side structures remain coated. They said Tesla considered films and other alternatives, and described scratches as repairable in a way similar to conventional paint.
How Modular Assembly Could Change Production
The process matters because it moves work to smaller, more accessible assemblies instead of requiring workers or robots to reach into a largely assembled car. Tesla’s stated rationale is that breaking the vehicle into sections improves access and lets stations sit closer together. If that design works at scale, it could reduce the footprint and complexity associated with a conventional body-and-paint sequence.
For buyers and operators, the method could also affect repairs. Tesla says the Cybercab uses replaceable battery modules and has components arranged for easier access, which may simplify some service work. The company has not provided repair-time comparisons, costs or reliability data in the material described by InsideEVs, so the practical benefits remain unquantified.
Production capacity is another reason to watch the line. Tesla says it can make 125,000 Cybercabs per year at full speed. That is a stated capacity, not evidence of current annual output or customer deliveries. The distinction matters because a factory designed for high volume does not show how quickly vehicles are being built, deployed or put into service.

Tesla’s Unboxed Design Takes Shape
Tesla has discussed an “unboxed” manufacturing approach for several years. Moravy said in the video that the idea took shape about six years ago, after the company struggled to automate existing vehicle designs and concluded that the vehicle’s construction was part of the problem. In the approach described, the answer is to divide the car into units that can be worked on independently before final joining.
The Cybercab is the production example covered in the tour at Tesla’s Texas factory. The report says the line does not operate every day because Tesla can build Cybercabs faster than it is currently deploying them. That account comes from the report and does not establish the factory’s daily output, utilization rate or the number of vehicles being deployed.
Tesla is not the only automaker exploring a modular alternative to a traditional assembly line. InsideEVs reported that Ford is developing a related approach for its Universal Electric Vehicle platform, describing its method as an “assembly tree.” The comparison is limited: the source does not provide enough detail to establish how closely Ford’s process matches Tesla’s.
“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, as quoted in the Munro & Associates video
Output, Repairs and Rollout Remain Open
The source does not give a current Cybercab production total, a delivery or deployment schedule, or a factory-utilization figure. It reports that the factory does not run every day because production can exceed deployment, but it does not provide numbers to show the size or duration of that gap. Tesla’s stated 125,000-unit annual capacity should not be read as a forecast or present-day production rate.
It is also unclear how much the process will reduce manufacturing costs, production time or repair bills compared with conventional methods. Tesla’s statements about access and replaceable battery modules describe design goals and features, but the source contains no independent repair data or long-term reliability results. The source does not detail the Cybercab’s full commercial operating plan or when deployments may expand.
Watch for Production and Deployment Data
The next meaningful test is whether Tesla can turn the line’s stated capacity into sustained production and broader deployment. Future company updates would need to clarify actual Cybercab output, how many vehicles are being put into service, and whether the factory’s operating schedule changes as deployments grow.
More information on repair procedures, component replacement costs and the durability of the molded exterior would help establish whether the manufacturing choices produce the service benefits Tesla describes. Until such data are available, the factory tour offers a detailed account of the process, but not proof of its performance at full scale.
Key Questions
What does Tesla mean by “unboxed” production?
Tesla builds the Cybercab’s front, rear, sides and floor as separate sections, then joins them late in the process. Much of the wiring and interior work is done before those sections meet.
How many stations are on the Cybercab’s final assembly line?
The report says the final line has about 25 stations. Tesla engineering chief Lars Moravy compared that with roughly five to 10 times as many stations for the Model Y.
Does the Cybercab use a conventional paint shop?
No traditional paint shop is described for the exterior panels. Tesla says the plastic panels are molded with color; the source also says the steel side structures remain coated, while the front and rear structural modules skip electrocoating.
Is Tesla already producing 125,000 Cybercabs a year?
No. 125,000 vehicles per year is Tesla’s stated capacity for the line at full speed, not its current output. The source gives no annual production total or detailed deployment schedule.
What remains unknown about Cybercab production?
Current output, factory utilization, deployment pace, manufacturing costs and real-world repair costs are not provided. The reported factory tour describes the process, but does not establish how it performs over time at full production scale.
