Honda and Nissan signed a joint development agreement Aug. 31 to standardize ECUs, the in-vehicle OS, middleware and vehicle-control software for fiscal 2029.
No merger or new company; engineers will write the same code for future gas, hybrid and electric models.
The shared OS aims to enable over-the-air software updates that add features after purchase.
Honda and Nissan just told the world what they are actually building together—and it is not a merger. The two companies signed a joint development agreement on August 31 to standardize the electronic control units, in-vehicle operating system, middleware, and vehicle-control software that will run their next-generation cars.
The target is fiscal year 2029. Nothing here creates a shared platform or a new company, but it does mean Honda and Nissan plan to put the same jointly developed code into the computers that will sit inside future gasoline, hybrid, and electric models from both brands.
