Q&A

• How is Tesla planning to use the next generation platform for new models?

  Tesla plans to use aspects of the next generation platform for new models produced on current manufacturing lines, potentially including a new cheaper vehicle. The company's shift towards autonomy and the challenges of large castings are influencing its manufacturing decisions, indicating a strategic and forward-thinking approach to its production processes.

• What are the concerns and challenges surrounding the use of large castings in vehicle manufacturing?

  Challenges such as higher scrap rates, repair costs for large castings, and the influence on manufacturing decisions, especially in weight reduction and production, are influencing the decisions of automakers. However, Tesla is focused on making car repairs cheaper and faster through the use of durable large cast aluminum parts, design changes, and collaboration with the collision repair team to address these concerns and challenges.

• Which automakers are investing in giga casting technology?

  Tesla and Volvo are leading the way in adopting giga casting technology, while other major automakers such as Ford, General Motors, and others are also investing in this technology, aiming for efficient and cost-effective production, weight reduction, and increased range in their vehicles.

• How does giga casting contribute to electric vehicle (EV) development?

  Giga casting is essential for EVs with heavy battery packs to reduce weight and can help close the cost gap with steel, making giga casting components about 30% cheaper than stamped parts. It also reduces vehicle weight by 10% and increases range by 14%, while providing an opportunity to change the way cars are made through flexibility in product portfolios and easier product upgrades.

• What car models does Tesla use large giga casts in?

  Tesla uses large giga casts in the Model Y, Model 3, and Cybertruck to enable lighter, cheaper, and more efficient car manufacturing. This technique also allows for improved noise, vibration, and harshness characteristics, manufacturing efficiency improvements, and simultaneous building of different parts of the car, reducing the size of its assembly line by 10%.

• What is mega/giga casting in the auto industry?

  Mega/giga casting is a manufacturing technique aimed at making electric vehicles (EVs) cheaper, lighter, and simpler by creating single casts for large sections of the vehicles, replacing traditionally stamped steel or aluminum structures. It enables design flexibility, cost savings, and the opportunity to rethink designs for a wider variety of shapes, ultimately reducing weight and improving efficiency.
