Tesla’s Gigacasting Technique Sparks Competition in the Automotive Industry

In a surprising move, General Motors (GM) has acquired Tooling & Equipment International (TEI), an automotive supplier based in Michigan that specializes in gigacasting, a technique pioneered by Tesla. This acquisition is part of GM’s strategy to catch up with Tesla’s advancements in automotive production.

Gigacasting involves the creation of alloys and heat-treating larger parts, allowing for quicker and more efficient car manufacturing. By purchasing TEI, GM gains access to the expertise and innovation behind Tesla’s gigacasting molds, enabling them to accelerate their own production capabilities.

With TEI now under its wing, GM plans to utilize the company’s sand casting techniques to develop more complex components, reducing the cost and time required to build cars. This acquisition has jump-started GM’s push to compete with Tesla, especially as the electric vehicle market becomes increasingly competitive.

Meanwhile, Berkshire Hathaway, Warren Buffet’s conglomerate holding company, has reportedly divested from its holdings in GM. Over the past decade, GM has seen negative returns, which may have influenced Berkshire Hathaway’s decision to sell approximately 22 million shares of the automaker. Notably, Berkshire Hathaway now holds a record cash position of $157 billion, raising questions about their future investment strategies.

In other automotive news, the development of semi-solid state batteries, which utilize a gel-like substance to facilitate faster ion diffusion, could revolutionize the electric vehicle industry. These batteries offer a potential solution to the limitations of current lithium-ion batteries, such as packaging, safety, and performance issues. Experts believe that semi-solid state batteries are a feasible and promising alternative to traditional solid-state batteries.

Additionally, the Insurance Institute for Highway Safety (IIHS) has released a report highlighting the safety concerns posed by larger, bulkier vehicles. The study reveals that vehicles with higher hood heights and blunt front ends are more likely to cause pedestrian fatalities. Manufacturers are urged to consider lowering the front end of hoods and adjusting the angle of grilles to mitigate these risks.

As Tesla’s gigacasting technique ignites competition among automakers, the future of car manufacturing and battery technology promises to be dynamic and transformative.


1. What is gigacasting?
Gigacasting refers to a production and prototyping technique pioneered by Tesla that involves the creation of alloys and heat-treating larger and larger parts for more efficient car manufacturing.

2. How does semi-solid state battery technology work?
Semi-solid state batteries utilize a gel-like substance that allows for faster ion diffusion, providing potential solutions to the limitations of traditional lithium-ion batteries.

3. Why did Berkshire Hathaway divest from GM?
Berkshire Hathaway made the decision to divest from GM due to the automaker’s negative returns over the past decade. The company currently holds a record cash position and is exploring alternative investment opportunities.

4. How can vehicle manufacturers improve pedestrian safety?
The IIHS recommends that manufacturers lower the front end of hoods and adjust the angle of grilles to reduce the risk of pedestrian fatalities caused by larger, bulkier vehicles.
