Honda And Nissan signed An Joint Venture Agreement On Electronics And Software Development

The failed negotiations on the merger of Honda and Nissan did not mark the end of their cooperation. Namely, the two large Japanese manufacturers have signed an agreement on the joint development of electronics and software for new-generation cars, and the first models that will use the joint technology should arrive in fiscal year 2029, that is, from April 2029.

The collaboration will not mean that future Nissan and Honda cars will become the same cars with different logos. The focus is on what the driver mostly doesn’t even see: the basic electronic and software architecture. The companies will jointly develop and standardize a number of key electronic control units, including powerful central computers and zone controllers, as well as the vehicle’s operating system, key pieces of middleware, and software that manage individual car functions.

Such cooperation is becoming more and more important as the car turns from a mechanical product into a so-called software-defined vehicle, or SDV. More and more functions, from powertrain operation and driver assistance systems to infotainment and later upgrades, depend on software. The development of such systems is extremely expensive, and Chinese manufacturers such as BYD have increased the pace of introducing new digital functions in recent years. Honda and Nissan, therefore, want to reduce costs, accelerate development, and achieve greater economies of scale through joint development.

For buyers, the result could be interesting. The basic operating system and electronic architecture could be common, while each brand will still be able to develop its own user interface, menu design, and character of individual functions. Similar to smartphones, the hardware and software foundations can be close, and the final experience different enough.

The deal is also interesting because of the events of 2025, when Honda and Nissan broke off talks on a much more ambitious merger that could have ended up creating one of the world’s largest automotive groups. After the collapse of those negotiations, both companies emphasized that they will continue to cooperate in fields where it makes economic sense. Software has proven to be one of the most important.

The story could also include a third Japanese manufacturer. Mitsubishi, which is part of an alliance with Nissan, is considering joining the joint software and electronics project, according to Reuters.
