BYD, the Chinese EV manufacturer, delivered 4.6 million vehicles in 2025, making it the world’s largest electric vehicle maker by volume.

Americans mostly know the name from trade headlines around tariffs and national security investigations. What gets less attention is that BYD manufactures roughly 75% of the components inside its own vehicles, a level of vertical integration not seen since the inception of Ford. It’s a sharp contrast to American automotive manufacturers who rely on a network of suppliers.

Our latest Scan of the Month covers four BYD parts: a lithium iron phosphate battery cell, a window switch panel, a portable EV charger, and a key fob. Follow our link in bio to scroll through the scans to see what the world’s largest EV manufacturer is building. 🔗

Our newest Scan of the Month covers four headphones from $80 to $550 to show what that trajectory has manifested into. Follow our link in bio to scroll through our latest Scan of the Month.
