Giga Texas Test Track Expands: Geotextile Work Underway as 30+ Cybercabs Spotted on Campus

March 9, 2026 • Giga Texas, Austin TX

Despite heavy fog rolling across Austin on March 9, 2026, drone operator Joe Tegtmeyer captured some of the clearest signals yet that Giga Texas is shifting into a new gear. The new test track site in the far southwest corner of the campus has visibly expanded, with geotextile membranes laid and infill work actively progressing. Meanwhile, more than 30 Cybercabs were spotted in motion — on transport trucks and at the crash testing facility — and construction at the North Campus continues to push forward.

The Test Track: Why Geotextile Membranes Matter

Geotextile membranes are a foundational construction material — they stabilize soil, manage drainage, and prepare a surface for the compacted base layers that a high-speed test track demands. Their presence, combined with active infill work, tells us this isn't early-stage land clearing anymore. Tesla is building the actual track bed.

According to verified site reports from earlier this month, crews had already been removing conduit risers, filling drainage ditches, and leveling on-site ponds in the southwest corner of the campus. The March 9 footage confirms that work has accelerated into the next phase. For context, a dedicated on-campus test track gives Tesla engineers the ability to validate vehicle dynamics, ADAS behavior, and emergency braking without relying on public roads or leased facilities — critical for a vehicle like the Cybercab that has no manual override.

30+ Cybercabs: What the Numbers Tell Us

Just six days ago, on March 3, observers counted 25 Cybercabs across the Giga Texas campus — 14 at the factory exit, 9 at the crash testing facility, and 2 at the west End-of-Line area. Today's count of 30+ units, now also moving via transport trucks, suggests production throughput is climbing and logistics pipelines are being stress-tested ahead of the April volume production ramp.

The first production Cybercab rolled off the Giga Texas line in mid-February 2026, roughly six weeks ahead of the originally anticipated April start for mass production. The fact that crash testing activity remains high while transport logistics are simultaneously active points to parallel workstreams — Tesla isn't waiting for one phase to complete before starting the next.

North Campus: The Optimus Factory Taking Shape

Construction activity at the North Campus is also visible in today's footage. Permits filed with the Travis County Permit Office designate this area for new Optimus production and support facilities. The stated ambition is staggering: ten million Optimus robots per year, with the factory projected to begin operations in 2027. Ground leveling and clearing have already commenced.

This is a longer-horizon story, but the groundwork being laid now — literally — will determine whether that 2027 timeline holds. For Tesla owners, the North Campus represents the company's biggest bet beyond vehicles: a humanoid robot manufacturing operation that, if it reaches even a fraction of its stated capacity, would fundamentally reshape Tesla's revenue profile.

🔭 The BASENOR Take

📰 Deep Dive

The expansion of Giga Texas is no longer a future-tense story. What's happening on the ground right now — geotextile membranes going down, Cybercabs moving in growing numbers, North Campus earthwork underway — is the physical manifestation of Tesla's most aggressive manufacturing buildout in its history. The planned addition of over 5.2 million square feet by end of 2026 would bring the total campus footprint to roughly 15 million square feet, making it one of the largest single manufacturing sites in North America.

The test track expansion is the detail most directly relevant to near-term Cybercab deployment. An autonomous vehicle without a steering wheel or pedals has a fundamentally different validation requirement than a conventional car. Every edge case — emergency braking, obstacle avoidance, sensor behavior in adverse weather — needs to be reproducible on demand. A dedicated on-campus track makes that possible at a scale and speed that off-site facilities simply can't match. The fog that hampered today's aerial footage is, ironically, exactly the kind of condition Tesla needs to test against.

The Cybercab logistics picture is also worth watching closely. Transport trucks moving 30+ units in a single day's observation window suggests Tesla is beginning to build inventory or distribute vehicles to testing hubs beyond Austin. Whether those destinations are service centers, autonomous fleet staging areas, or regulatory testing facilities remains to be confirmed — but the movement itself is a meaningful signal that the program is transitioning from factory validation to broader operational readiness.

For the longer view: the North Campus Optimus factory, if it delivers on its permit-filed ambitions, would make Giga Texas something qualitatively different from any other Tesla facility. It would be simultaneously a vehicle factory, a robotaxi production hub, and a humanoid robot manufacturing plant — all on one campus. Today's foggy flyover is a small window into a construction story that will define Tesla's next decade.
