Tesla's Manufacturing Edge: A Temporary Advantage in EVs
Written on
Chapter 1: The Changing Landscape of Tesla's Advantages
Tesla once stood unchallenged in the electric vehicle (EV) market, but that scenario is shifting. In recent years, a growing number of EVs have emerged that offer faster charging times, longer ranges, advanced driver assistance systems, superior interiors, and better acceleration—all at comparable or lower prices than Tesla's offerings. Even Tesla's once-unique charging network is becoming less exclusive, as it opens up to other brands and as third-party rapid charging stations proliferate. Nevertheless, there remains one area where Tesla still excels: manufacturing.
As Tesla's gigacasting technology allows them to produce EVs more swiftly and economically than any competitor, they maintain a stronghold in this domain. However, this advantage is on the verge of diminishing. Here’s why.
Section 1.1: Understanding Gigacasting Technology
Gigacasting, while not a Tesla invention, was first effectively implemented by the company. This innovative approach simplifies and reduces the cost of chassis production. Traditional car chassis consist of numerous welded components shaped from metal sheets, making the process labor-intensive and time-consuming. In contrast, gigacasting employs massive machines to inject molten metal into molds under significant pressure, creating large aluminum components, and in some cases, entire frame sections.
The ability to cast such large parts with high precision and quality is a challenging feat, requiring these machines to exert thousands of tonnes of pressure to ensure that the molten metal perfectly conforms to the mold.
Subsection 1.1.1: The Efficiency of Gigacasting
Tesla first harnessed gigacasting technology in 2019 for the Model Y assembly line, with the initial gigapress producing the rear floor section of the chassis using a force equivalent to 9,000 tonnes!
So, why did Tesla opt for this technology? The reason lies in its efficiency. Gigacasting is considerably faster than traditional welding methods, which are often bottlenecks in production. By speeding up the chassis fabrication stage, Tesla enhances the overall efficiency of its manufacturing process. Furthermore, this method requires fewer highly skilled workers, thereby lowering operational costs. The automation of gigacasting also allows for flexible scaling without incurring significant expenses, making chassis production through this method notably cheaper than through welding.
Section 1.2: The Competitive Landscape
Despite Tesla's lead, gigacasting is not exclusive to them. Other automotive manufacturers—such as Volvo, Toyota, Mercedes, VW, GM, and Hyundai—are quickly integrating their own gigacasting technologies. Notably, BYD, Tesla's primary global competitor, has already implemented gigacasting in many of its electric vehicles. Additionally, Toyota is exploring the possibility of casting entire chassis sections in a single piece after collaborating extensively with BYD.
Chapter 2: Future Implications for Tesla
This swift adoption of gigacasting will greatly impact the EV sector by driving down production costs across the board. A recent Gartner report predicts that by 2027, EVs will be less expensive to purchase than traditional combustion engine vehicles, thanks in part to this rapid technological advancement.

The second video, "E93: Tesla's 3 Bold Moves: Too Risky?" delves into Tesla's strategic decisions and their implications for the future of the company.
As these manufacturing technologies become more widespread, Tesla's significant advantage will likely diminish. The high cost of gigacasting machinery necessitates long-term utilization for companies to achieve the anticipated economies of scale. As rivals like Toyota push the boundaries of this technology further, lowering production costs even more, Tesla may find it increasingly challenging to keep pace.
This does not imply that Tesla vehicles will become obsolete in the near future; they will continue to be high-quality electric vehicles with advanced technology. However, they may transition from being market leaders to just another participant in the evolving EV landscape.
