Nissan, Honda deepen ties with software joint development

Japanese automakers Nissan and Honda have entered an agreement to jointly develop standardized electronic control units (ECUs) and software for software-defined vehicles (SDVs), according to reports from multiple news outlets on Monday. The companies plan to introduce a shared architecture in next-generation vehicles from the 2029 financial year onwards.

Shared components in focus

Under the deal, the two automakers will standardize parts in 'core ECUs' as well as software. This partnership is designed to reduce development costs and speed up the launch of new technologies. The agreement, which did not specifically mention EV models, is focused on creating vehicles whose features can be updated and controlled by software, according to a joint statement cited by multiple outlets.

Industry context and competition

This collaboration comes as software becomes a central battleground for the auto industry, with increasing investments needed for operating systems that support features from driver assistance to over-the-air updates. The move is seen as a response to growing competitive pressure, particularly from Chinese automakers like BYD, which have gained ground with software-rich electric vehicles.

Background of talks

The agreement follows initial discussions between the two companies in 2024 to explore joint research on next-generation software platforms. It also comes over a year after they called off merger talks.

Potential expansion

Nissan's alliance partner, Mitsubishi Motors, has stated it is considering joining the collaboration, according to reports.

Global collaborations

The companies are not alone in this effort. European manufacturers such as Volkswagen, BMW, and Mercedes-Benz are also working together on software development, and Toyota is collaborating with companies like Subaru and Waymo.
