Following Tesla's 1.64 million vehicle deliveries in 2025—a 9% decline that handed the global battery EV lead to BYD's 2.26 million—regional sales drops in Europe (nearly 30%) and China (first since 2020) have fueled debate. Tesla's reliance on just two main models contrasts with BYD's 30-model portfolio, potentially missing opportunities to sustain growth amid rising EV demand.
Tesla's 2025 performance included a 41% US market share but only 6% in Europe and 5% in China, yielding a global 12% battery EV share behind BYD's 17%. This marked declines across major markets despite overall EV sales growth, with Model 3 and Y still topping regional charts.
Recent coverage highlighted sales figures and factors like ended US tax credits and competition, but overlooked Tesla's stagnant lineup. In the late 2010s, the company bet on full self-driving tech for demand, projecting 50% yearly growth to 20 million annual sales by 2030. Model 3 (2017) and Y (2020) became the sole mass-market vehicles, with Cybertruck deliveries starting November 2023 but underperforming.
By 2026, full self-driving progress stalled without a pivot to lineup expansion. BYD, meanwhile, maintained about 30 battery electric models and launched nine new ones in 2025. Analysts argue a broader Tesla range—say, 15 models with four or five debuts last year—could have built hype, countered two years of downturn, and kept enthusiasm high in a booming industry.
