A recent teardown event in Japan showcased BYD's affordable electric vehicle (EV), the Atto 3. The analysis revealed that BYD's in-house production and integration of components, such as the "E-Axle," contribute to its affordability. This approach, combined with economies of scale, enables BYD to offer high-quality EVs at a lower price point than some competitors. The event also highlighted the differences in quality standards between Chinese and Japanese manufacturers.
