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.

Japan’s second- and third-largest automakers hope the $50 billion deal would help them catch up with Tesla and China’s BYD in electric vehicles and advanced software.

Speculation about a potential Honda and Nissan merger began earlier this month, and the two companies confirmed the official start of talks Monday.
