Tesla appears to be pursuing two parallel bets in Texas: a far larger Giga Press that could simplify vehicle production, and a purpose-built Cybercab network designed for commercial autonomous service.
Tesla is linked to a new generation of Giga Press technology at Giga Texas, with a reported clamping force of up to 50,000 tons. That would be a major jump from the company’s earlier 6,100-ton, 9,200-ton, and 16,000-ton machines. The goal is not simply a bigger press, but the ability to produce very large structural castings at far higher throughput.
In high-pressure die casting, the headline tonnage refers mainly to the force holding the mold shut while molten aluminum is injected. As castings grow, surface area and internal pressure rise, increasing the risk of the die separating. A machine at this scale would need to keep a massive mold locked under extreme pressure while still operating at industrial speed.
The process described for the new system relies on a dual-furnace setup, with molten aluminum first melted around 850°C and then held between 750°C and 850°C. Nitrogen, argon, rotary degassing, and silicon carbide filtration are used to reduce oxides and contamination. Before each cycle, a robot sprays about 35 ml of soybean oil on the mold, the chamber is vacuumed, and a piston injects the metal at high speed.
The cast part reportedly exits at about 400°C and is cooled rapidly to near 50°C, while the mold itself is prepared again at around 185°C. Full cycle reset is described at roughly 1 to 2 minutes, even though the structural forming step is much faster. That emphasis on ultra-fast cooling helps explain why Elon Musk has framed the challenge as one of physics as much as machinery.
Large castings let automakers replace dozens of welded pieces with one part, cutting steps, tooling, and floor space. Tesla has claimed this approach can reduce the number of robots on a line from roughly 1,000 to 300. The broader aim is not just more automation, but eliminating entire stages of conventional body assembly.
Early skepticism focused on tool wear, repair costs, and whether giant aluminum castings made economic sense. Even so, major manufacturers including Ford, Hyundai, Toyota, GM, and Volkswagen have explored or invested in similar high-pressure casting methods. That suggests large-scale casting is shifting from a Tesla experiment toward an industry manufacturing trend.
Concerns that one damaged area would force replacement of an entire casting have softened as repair procedures improved. For the Model Y rear mega-casting, technicians can in some cases cold-straighten sections, weld minor cracks, reinforce areas, or replace parts of the rear rail. Findings from Thatcham Research in 2025 indicated that, in cases examined, repairing the Model Y structure could be about $2,800 cheaper than a comparable Model 3 steel rear structure, while full casting replacement was still roughly $675 cheaper.
Separately, Tesla is preparing a September 3, 2026 event in Austin tied to a Cybercab self-driving taxi launch. Vehicle activity has accelerated, with about 40 units reportedly seen at a Dallas-area autonomous taxi site in mid-June 2026, rising to nearly 100 within about two months. The Irving, Texas facility is said to hold up to 212 autonomous vehicles and appears designed for charging, maintenance, dispatch, and remote monitoring.
The Cybercab is described as using more powerful self-driving computers than current AI 4 vehicles, though Tesla has not confirmed whether the setup is AI 5 or an upgraded variant. Exterior cameras reportedly have dedicated washing systems, and the vehicle is expected to use Starlink connectivity for fleet communication. The design points to a vehicle intended for continuous, driverless commercial use rather than occasional private driving.
An EPA filing reportedly points to a 53.3 kWh battery, up to 418 miles of range, and efficiency of at least 5.5 miles per kWh. The vehicle is also said to use a 219-horsepower front-wheel-drive motor and weigh about 3,113 pounds. Wireless inductive charging is widely expected, a feature that would allow an autonomous taxi to recharge without human assistance.
Tesla’s strategy in Texas centers on redesigning both the factory and the vehicle around fewer steps, higher throughput, and software-led operation. If the giant casting system and Cybercab network scale as planned, the company could reshape how cars are built and how they are used.
