Japan's Honda and Nissan said Monday they had embarked on formal merger talks that would create the third-largest car manufacturer globally with sales of as much as $191.4 billion and more than $19 billion profit.

Honda Motor Co. and Nissan Motor Co. plan to merge under a holding company with the top executives chosen by Honda in a historical reshuffling of Japan’s auto industry meant to keep the country’s second- and third-largest players competitive amid a global onslaught of new competitors and technologies.

Japanese automakers Honda and Nissan will attempt to merge and create the world’s third-largest automaker by sales as the industry undergoes dramatic changes in its transition away from fossil fuels.
