Founded in 1995 by Wang Chuanfu with origins in rechargeable battery manufacturing, BYD's evolution from battery supplier to automotive powerhouse represents one of the most remarkable transformations in modern industrial history. The company entered the automobile market in 2003, finding early success with the F3 sedan before pivoting toward electrification with the E6 EV in 2010. Warren Buffett's 2008 investment signaled the company's potential, validating BYD's vertical integration strategy that spans the complete chain from battery cells to finished vehicles. BYD became a leader in bus electrification and commercial vehicle electrification before experiencing explosive growth in passenger cars through both plug-in hybrid innovation and pure EV dominance. By 2023, BYD had achieved a milestone that seemed impossible just years earlier: becoming the world's largest EV maker, surpassing Tesla in sales volume. The company's technology leadership and manufacturing excellence showcase Chinese innovation on the global stage, disrupting traditional automotive hierarchies and proving that expertise in batteries could translate into complete vehicle mastery—fundamentally reshaping the global automotive landscape in the process.
