Toyota says it will bring “gigacasting” style EV manufacturing to a new Lexus plant in China, while urging changes to EU rules

Toyota Motor is reportedly preparing to adapt “gigacasting” style manufacturing for electric vehicles at a new Lexus-branded plant in China, according to a report published Tuesday. Gigacasting refers to using very large casting machines to produce major vehicle structural components in fewer pieces, a process that can shorten assembly steps and potentially reduce material and labor complexity.

The report ties Toyota’s manufacturing plan to the broader way Tesla popularized large-format casting in some of its vehicle production. While Toyota has been associated publicly with electrification and platform investments, the new detail here is the specific manufacturing technique, and its location in a China-based Lexus facility.

In the same report, Toyota is also described as pushing for rule changes in Europe related to how large casting processes are treated by regulators. The story frames the effort as an attempt to align European requirements with manufacturing approaches being adopted in other auto markets, particularly for EV production.

Toyota did not provide additional specifics in the text available for this story about what precise EU regulations it wants changed, how its China line will be set up, or when output from the Lexus plant would begin. The reporting also does not lay out the expected economic impact, such as cost targets, annual capacity, or sourcing arrangements for casting equipment and upstream parts.

For Toyota, the manufacturing focus matters because large casting can reshape how a vehicle body is engineered and assembled. Consolidating components can affect press and stamping content, supplier relationships, and the way quality assurance is performed for large cast structures. If successfully implemented at scale, the approach could help automakers improve production efficiency while keeping EV body production aligned with new battery and powertrain packaging.

More broadly, the European policy angle underscores a recurring tension in auto manufacturing: technology adoption can move faster than rulemaking, especially when regulators must consider new processes for safety, environmental performance, and structural integrity. Automakers that deploy advanced manufacturing globally often find themselves managing a patchwork of compliance requirements, which can add friction and cost.

What remains unclear from the available report is whether Toyota’s “gigacasting” plan will be used for the entire vehicle body or only for selected major components, and whether Toyota is pursuing the approach through internal engineering, external partnerships, or equipment supplier licensing. The timeline for the China facility and the scale of the first phase of production are also not disclosed in the provided coverage.

Toyota’s next public disclosures, including potential updates in company announcements tied to the China plant or investor communications around EV manufacturing strategy, will likely determine how concretely the gigacasting plan is defined. Separately, any official comments or submissions regarding the EU rule changes would indicate which parts of the regulatory framework Toyota believes are in need of adjustment, and how quickly it expects regulators to respond.
