Toyota Takes Majority Stake in New Joint Venture with Joby to Mass-Produce eVTOL Aircraft

For nearly a decade, the promise of electric air taxis has hovered just over the horizon, constrained by the immense difficulty of transitioning from prototype to mass production. That barrier shifted significantly this week when Toyota Motor Corporation and California-based Joby Aviation announced the formation of a formal joint venture to manufacture electric vertical takeoff and landing (eVTOL) aircraft. The new entity, named the Joby Toyota Aero Manufacturing Preparation Company, represents a critical milestone in the race to commercialize urban air mobility.

The joint venture is designed to combine Joby’s pioneering electric aviation technology with Toyota’s globally recognized expertise in high-volume production systems. Under the agreement, Toyota will hold a 51 percent majority stake, while Joby retains 49 percent. This structure gives the Japanese automaker operational control over the manufacturing process, a move that industry analysts view as a massive de-risking event for the aerospace startup.[1]

While designing and certifying a novel aircraft presents steep regulatory hurdles, manufacturing these vehicles at scale with automotive-style efficiency is an entirely different challenge. Aerospace startups historically struggle with the transition to mass production, often facing supply chain bottlenecks and quality control issues. By securing a majority-stake commitment from Toyota, Joby gains direct access to the legendary Toyota Production System, which emphasizes continuous improvement, defect reduction, and lean manufacturing.[2]

The financial mechanics of the joint venture itself are relatively modest, with Toyota purchasing 1.02 million shares for $1.02 million and Joby buying 980,000 shares for $980,000. However, this nominal capital belies the massive financial engine behind the partnership. The joint venture is the culmination of years of investment, with Toyota having injected approximately $894 million into Joby since 2017, making it the startup's largest institutional shareholder with a roughly 13 percent overall holding.[1][2]

Governance of the new manufacturing company reflects Toyota's controlling interest. The five-member board of directors will feature three members designated by Toyota and two by Joby. Major strategic actions will require approval from both parent companies, but critical financial decisions regarding debt and dividends will rest firmly in Toyota's hands. This setup ensures that the automaker can enforce its rigorous financial and operational discipline as the facility scales.[1]

The focal point of this manufacturing alliance is Joby’s S4 Series eVTOL. The aircraft is a marvel of modern engineering, featuring six tilting propellers that allow it to take off and land vertically like a helicopter, before transitioning to forward flight like a traditional airplane. Designed to carry four passengers and a pilot, the all-electric vehicle boasts a top speed of 200 miles per hour and operates with a fraction of the noise produced by conventional helicopters.[3]

To build the S4 at the scale required for a global air taxi network, the joint venture will rely on a complex intellectual property sharing agreement. Joby will license its proprietary aircraft-related intellectual property to the joint venture on a royalty-free basis. In exchange, Toyota will license its manufacturing-related intellectual property to the venture, which includes certain royalty-bearing rights. This symbiotic exchange ensures that the factory floor has the legal and technical clearance to optimize every step of the assembly line.[1]

The collaboration between the two companies is not new. Toyota engineers have been working side-by-side with Joby’s team in California for years, providing hands-on assistance in developing aircraft production technologies. This deep integration has allowed Toyota to understand the unique material and safety requirements of aerospace manufacturing, while teaching Joby’s engineers how to design components that are easier and cheaper to mass-produce.

Currently, Joby operates a pilot production line in Marina, California, and a facility for manufacturing propeller blades in Dayton, Ohio. The newly formed joint venture will initially focus on establishing the groundwork for commercial production at these sites, with a particular emphasis on improving productivity, quality, and cost efficiency. As demand grows, the alliance plans to develop a global manufacturing footprint that could include additional high-rate production facilities.[2]

Despite the manufacturing breakthrough, significant regulatory hurdles remain before the S4 can begin ferrying passengers across city skylines. Joby has secured its air carrier operator certificate from the U.S. Federal Aviation Administration (FAA), but it is still in the concluding stages of earning its aircraft type and production certificates. The joint venture is explicitly designed to support this certification process by proving to regulators that the aircraft can be built consistently and safely at scale.[2]

The urgency to finalize production capabilities is driven by an intensifying global race for airspace. Joby faces stiff competition from rivals like Archer Aviation, which is also aggressively pursuing FAA certification and scaling its own manufacturing operations. The stakes are high, as the first companies to market will have a significant advantage in securing lucrative routes and establishing consumer trust in a completely new mode of transportation.

Joby’s ambitions extend far beyond the United States. The company recently announced a partnership with Uber to launch an on-demand air taxi service in the United Arab Emirates, aiming to begin operations later this year. Because the UAE often aligns its aviation approvals with FAA guidelines, achieving U.S. certification and demonstrating robust manufacturing capabilities through the Toyota joint venture will be critical to unlocking these international markets.

Ultimately, the Joby-Toyota alliance represents a paradigm shift in how aircraft are built. By treating an eVTOL more like a high-end automobile than a bespoke aerospace project, the joint venture aims to drive down costs and increase accessibility. If successful, this fusion of Silicon Valley aviation innovation and Japanese manufacturing discipline could finally transform the long-held dream of everyday aerial mobility into a commercial reality.[3]
