Tesla could face emissions credit tax in Washington

Tesla’s Gigafactory in Texas is building what appear to be castings for the upcoming Cybercab, ahead of the vehicle’s launch and the highly anticipated debut of Unsupervised Full Self-Driving (FSD).
On Monday, Tesla Giga Texas site observer Joe Tegtmeyer shared photos on X of some unique castings out beside the factory. Notably, Tegtmeyer points out that the castings are quite different from those of the Model Y and Cybertruck, which are currently the only two vehicles being produced at the Austin, Texas plant—at least publicly.
Some viewers noted that the castings appear to have a similar shape to the Cybercab, along with being one single casting, compared to the two-piece Giga casts the factory produces for the Model Y and Cybertruck. The shape appears to be consistent with Tesla’s unboxed production process, which is expected to build single-piece castings and will be used for the upcoming Cybercab.
You can see Tegtmeyer’s photos of the castings below, in comparison with the Cybercab body and castings for the Model Y and Cybertruck.

In March, Tesla Vice President of Vehicle Engineering Lars Moravy confirmed in an interview with manufacturing expert Sandy Munro that Cybercab production would be starting prototype builds this summer, while the automaker is aiming to ramp for volume production in 2026.
While it isn’t summer yet, executives also confirmed in January that Cybercab production lines were already being prepared at Giga Texas, so it’s not unlikely that these castings are some of the upcoming vehicle’s first prototype builds.
The unboxed production process is also expected to revolutionize the automotive manufacturing industry, with CEO Elon Musk emphasizing how different the production line looks compared to its past vehicles during the Q1 2025 All-Hands meeting. Instead, Musk says the production line appears more like a high-speed consumer electronics line, and it’s expected to push Cybercab builds out in less than five seconds.
In a post on X earlier this month, Musk also reiterated that the Cybercab production line and the factory in general are essentially the products on their own, rather than just the cars themselves.
“The Tesla factory, especially our next gen Cybercab line, is the product,” Musk said. “That, autonomy and Optimus, are what matter.”
Tesla is also aiming to launch its first commercial robotaxi services around Austin, Texas this summer, along with launching its first iterations of Full Self-Driving (FSD) Unsupervised. The company is also holding its Q1 earnings call on Tuesday, during which executives are expected to address questions about the Cybercab and the upcoming commercial robotaxi service.
