Tesla Giga Texas Car Production

Tesla · Model Y, Model Y L, Cybertruck, Cybercab, Roadster · SH 130, Travis County

Four vehicles on four production architectures under one roof, and the Roadster coming in RFTX. Giga Texas is the only US source of the Model Y L and the home of the Cybercab's Unboxed line.

Overview

Five Vehicles, One Campus

Vehicles are the program Giga Texas was built for; Cortex, Optimus and the Terafab Research Fab came later. The 10-million-square-foot factory on SH 130 builds the Model Y, the six-seat Model Y L, the Cybertruck and the Cybercab, each on its own production architecture, and the Roadster is coming in a building of its own. Giga Texas is the only US plant building the Model Y L.

Tesla builds platform-distinct vehicles in one factory instead of shared platforms across many; the building, substation, supply logistics, workforce and rooftop solar are shared, and almost nothing at the body or assembly level is.

Roadster

RFTX and the Loop

The Roadster gets Roadster Factory Texas (RFTX), a dedicated building being planned and built on the campus, and a looping vertical track at Tesla's Texas headquarters where owners can try the stunts the car performs on its own. Lars Moravy and Franz von Holzhausen confirmed Giga Texas production in May 2026; the car is in testing with a tri-motor powertrain, a next-generation battery and the SpaceX cold gas thruster package Musk has described since 2017. No production date has been announced.

Megacasting

The Giga Press

Casting by vehicle
VehicleCastingPressStructural parts
Model YTwo-piece, front and rear underbody6,000-ton classAbout 200
CybertruckTwo-piece; 9,000-ton dedicated rear9,000-ton rearAbout 200
CybercabSingle-piece9,000-ton classAbout 80, 60% fewer than Model Y

IDRA Giga Presses cast whole structural sections in one shot. The 9,000-ton machines, the largest aluminum high-pressure die-casting presses in production, weigh about 410 tonnes and inject about 80 kg of aluminum at 10 m a second. One casting can replace up to 250 parts and cut body-structure weight by 10% to 30%.

Industry   Achieved   Target

The Unboxed Process, announced at Investor Day in March 2023, builds front, rear, floor-with-battery, sides and seats in parallel cells and joins them once at the end, for up to 40% less floor space and about half the capital per vehicle. The Cybercab line built its first car on February 17, 2026 and ramped in April. With about 80 structural parts, no steering wheel, pedals or mirrors, Tesla treats its assembly as closer to consumer electronics than to cars.

Cybercab meets federal motor vehicle safety standards, so Tesla self-certifies it and is not held to the 2,500-a-year exemption cap. Finished cars drive themselves off the line. On October 9, 2026, Texas registrations for Tesla Robotaxi reached 739 vehicles: 420 Model Y and 319 Cybercab. Musk has said material Cybercab revenue is unlikely before 2027.

Recursion

The Factory Builds Its Own Inputs

  • EnergyMegapacks and rooftop solar power the building that builds Megapacks and solar equipment
  • LogisticsTesla Semis move material into the factory
  • SoftwareCars drive themselves off the line, generating FSD training data
  • LaborOptimus robots built on the campus take on factory work
  • ComputeCortex trains the models for the vehicles, robots and floor automation

The roof carries a 30 MW solar array of about 70,000 panels, the largest rooftop installation Tesla has announced, with about 10 MW operating in phase one. Each vehicle carries an estimated 2,000 to 4,000 semiconductors; at 451,758 vehicles built company-wide in Q2 2026, that demand feeds the Terafab Research Fab next door.
