The rapid rise of Chinese electric vehicle maker BYD

Warren Buffet-backed BYD dethroned Tesla in the fourth quarter of 2023 as the world's top electric vehicle maker, selling more battery-powered vehicles than its U.S. rival. The Chinese carmaker is showing no signs of slowing down, becoming the top brand in China and growing exports by 334% last year. CNBC explores whether BYD can sustain its relentless growth and if it may one day enter the U.S. market.
