French auto parts supplier Forvia reported on July 31, 2026, that its sales in China plunged 19.3% in the first half of the year, citing weaker performance from major client BYD as a contributing factor. Forvia's finance chief, Olivier Durand, noted an "unfavourable mix of manufacturers" and stated that "BYD is performing slightly less well than before."
This external report provides a significant data point suggesting a slowdown in BYD's domestic activities. The news comes amid a challenging period for China's auto market. While Forvia's overall half-year sales drop of 4.3% was less than analysts feared, the steep decline in its China business highlights the material impact of BYD's performance on its supply chain partners.
