Toyota, like most major global automakers, is adopting Chinese EV technology to cut costs and keep pace with industry leaders such as BYD and Tesla. So far, it seems to be paying off for the Japanese automaker, widely considered one of the biggest laggards in the transition to BEVs.
The bZ3X, Toyota’s most affordable EV in China, starts at just 109,800 yuan, or about $15,000. From September 2025 through January 2026, the bZ3X was the best-selling new energy vehicle (NEV) among joint-venture brands in China. That includes battery-electric (BEV) and plug-in hybrid electric vehicles (PHEVs). Launched just over a year ago, the bZ3X started a so-called “bZ shock,” according to a new
report. Toyota and other Japanese brands, such as Nissan, are increasingly relying on China for parts and other EV components.
Toyota denies it, but several analysts estimate that nearly 90% of the parts used in the bZ3X are from China. Toyota’s Chinese joint venture, GAC Toyota, led the development. While the bZ3X has been a hit for Toyota with over 80,000 units sold in its first year, it’s having a bigger impact back home. The
Nikkei report claims most of Toyota’s linked suppliers in Japan, the “Toyota Keiretsu group,” lost their contracts as a result. While some believed Toyota would use only Chinese parts in the bZ3X, it has since launched the bZ5 and, most recently, the flagship bZ7 earlier this month, both packed with locally sourced parts. The bZ7 has around 30% Chinese components.
Toyota is also reportedly planning to use Chinese tech in EVs sold overseas in regions like Southeast Asia. And Toyota isn’t the only one.
