BYD is set to launch approximately 10 new models within a year, having already released 9 this year, while Tesla has introduced only the Cybertruck. Despite Tesla's profitability, its sales growth has stagnated compared to BYD's rapid expansion, attributed to a lack of new models. Tesla's focus on future technologies like robotaxis and AI may be impacting its conventional auto business, leaving it to compete with BYD, which has adopted a different strategy in the electric vehicle market.
