BYD’s Silent Takeover — How One Company Quietly Changed the World’s Bus Fleets

On December 27, 2017, Shenzhen made history by transforming its entire public bus fleet into electric vehicles. Behind much of that transformation was BYD—a company that had entered the bus industry only a few years earlier. While the world was focused on Tesla and the electric car revolution, BYD was quietly expanding its electric buses into major cities around the world. From Shenzhen to Bogotá, London, Santiago, and beyond, the company built its success around predictable bus routes, centralized charging depots, long-lasting LFP batteries, and lower operating costs. But BYD's rise didn't go unnoticed forever. As the electric bus market grew, competitors like Yutong entered the race, while political and national-security concerns created new challenges in markets such as the United States. This is the story of how BYD quietly helped transform public transportation—and built a global electric bus empire while most of the world was watching something else.
