Japanese automakers Nissan and Honda have announced plans for a merger that would catapult them to a top position in an industry that's in flux as it transitions away from its reliance on fossil fuels.

The proposed deal aims to unify operations under a joint holding company, led by Honda, while maintaining the distinct identities of each brand, according to Honda's president, Toshihiro Mibe.
