Agreement to establish a new company as a joint development centre and begin specific co-operative projects

Mazda Motor Corporation (Mazda), Denso Corporation (Denso) and Toyota Motor Corporation (Toyota) signed a contract today to jointly develop basic structural technologies for electric vehicles. Furthermore, they have also decided to establish a new company with engineers from each company to ensure the efficient implementation of the joint technological development projects.

As countries and regions around the world adopt increasingly stringent policies to help reduce greenhouse gases, new regulations that mandate a certain proportion of electric vehicle sales are beginning to emerge. Complying with these regulations, while ensuring the sustainable growth of our companies, requires the development of a wide range of powertrains and technologies. We regard electric vehicles (EVs) as a key technological field in this process, alongside fuel cell vehicles.

With EVs yet to find widespread market acceptance, the huge investments and time required to cover all markets and vehicle segments is a pressing issue for individual auto manufacturers when responding to the widely varying demand for vehicles around the world.

Mazda, Denso and Toyota have decided to jointly develop basic structural technologies for EVs capable of covering a wide variety of vehicle segments and types to ensure flexible and rapid response to market trends. This agreement covers a diverse range of models, including passenger vehicles, SUVs and light trucks, and aims to innovate the development process by combining the strengths of each company. This includes Mazda’s bundled product planning and prowess in computer modelling-based development, Denso’s electronics technologies, and the Toyota New Global Architecture (TNGA) platform.

The new company will engage in: –

  • Research into the characteristics (common architecture*) that define the optimum performance and functions of EVs from the standpoint of both individual components and the whole vehicle
  • Verification of component installation and vehicle performance realised by the characteristics achieved in item 1 above
  • Examination of the optimum concept for each car classification with regard to each component and each type of vehicle, realised by achieving items 1 and 2 above

* Common architecture is the basic product design concept for realising required product performance by distributing those requirements among structural components. Under the concept of a common architecture, the basic structure of each component can be made common, thereby transcending differences in vehicle class and power. By organising component characteristics, various products can be developed and produced through the same process.

Through this joint technological development project, Mazda and Toyota intend to focus their resources on fundamental vehicle values to enable the creation of appealing EVs that embody the unique identities of each brand and avoid the commoditisation of EVs, dedicating an equal amount of development resources, ensuring efficient development processes and taking advantage of existing production facilities.

The companies also aim to create a business structure that is open to participation by other auto manufacturers and suppliers.
