Nissan and Honda to co-develop vehicle software and core electronic units

Nissan and Honda announced a partnership to jointly develop hardware and software for vehicle electronic control units, targeting models that will enter the market in fiscal 2029. The agreement, stemming from discussions that started in 2024 about electric and intelligent driving technologies, focuses on sharing standardized ECU parts and software platforms. While the pact does not reference particular models or electric cars, it is intended to support the rise of software-defined vehicles whose features can be updated via code.

The collaboration is expected to reduce expenses, accelerate development cycles, and achieve economies of scale once production begins. Both companies highlighted that the partnership will also look into zero-emission initiatives and measures to lower traffic fatalities. The move positions the two firms to better compete with larger domestic rivals and aligns with similar European collaborations on automotive software.
