Documented cause
Proterra built electric transit buses for American public transit agencies, competing with diesel incumbents like New Flyer. The product was technically excellent and received strong government support and clean energy incentives. But Chinese electric bus manufacturers — BYD in particular — entered the US market with prices 30-40% lower than Proterra could achieve with domestic manufacturing. Supply chain disruptions post-2021 inflated component costs. Proterra filed for bankruptcy in August 2023 despite selling its product into favorable policy tailwinds.
Lesson
“US electric vehicle manufacturers need Buy American protections or they face an insurmountable cost disadvantage against Chinese manufacturers at scale.”
