Nearly two years after Elon Musk pitched the Robovan as a driverless, 20-passenger urban shuttle at under a dollar a mile, the vehicle resurfaced Thursday morning. Not on a production line. Not in a test fleet. In a concept render of a building that does not yet exist.
Musk posted a video of Terafab, the planned 2.5-mile-long joint Tesla-SpaceX-xAI facility in Grimes County, Texas. The clip, credited to SpaceX, showed Optimus robots tending landscaped grounds while a Robovan glided along an elevated roadway inside the building, flanked by a Tesla Semi and a Cybercab. The architecture looked like something pulled from a science fiction film — angular facades, illuminated horizontal bands, reflecting pools, sculptural spires on the skyline.
“Terafab Texas will be the largest and most valuable building on Earth by far,” Musk wrote. “And it will be stunningly beautiful.”
The Robovan has no confirmed production timeline. It has not appeared in any factory footage since the “We, Robot” reveal in October 2024. Thursday’s render is one of the only fresh looks at the vehicle in any official context, and it arrived embedded inside a promotional video for an entirely different project.
Optimus, by contrast, has tangible hardware moving. Tesla converted Fremont’s old Model S and X assembly line into a Gen 3 Optimus production line earlier this year. A second, larger plant is rising at Giga Texas with a volume production target of summer 2027 and eventual capacity Musk has pegged at 10 million units annually.
Tesla AI lead Ashok Elluswamy acknowledged this month that the robot has “big shoes to fill” replacing the S and X line. Musk has priced the finished product between $20,000 and $30,000 and called it the most consequential product in the company’s history.
The Terafab render dropped less than 24 hours after company representative Riley Trennell told Grimes County residents that renderings would be released “within days.” Texas Governor Greg Abbott’s office confirmed the project separately on Thursday. SpaceX has already sent the county a $10 million payment under a signed tax abatement agreement, and civil work and foundation prep are beginning almost immediately.
The capital expenditure figure tied to this phase, per Reuters, is $16.8 billion. SpaceX attorney Buck Brannon told residents the abatement runs roughly 78 percent, not the 100 percent some earlier reports claimed. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, totaling $710 million.
The company also pledged not to pull power from the ERCOT grid, planning instead to build its own natural gas plants.
Reaction on X split predictably. “God Bless Texas! Everything is bigger and better in Texas!” read one reply. Another was more measured: “Terafab in a decade…..”
That tension captures the entire story. Musk is simultaneously converting real factory floor space for Optimus, sending real checks to a Texas county, and releasing polished renders of a vehicle no one outside Tesla has touched. The Robovan remains a pitch deck item riding alongside products that have actual timelines and actual metal being bent.
Within hours, the video crossed 5.5 million views. Whether the finished building matches the render is one question. Whether the Robovan ever rolls off a line inside it is another one entirely, and Musk has not offered a date for either.
