Following the market's opening bell, JAC Motors witnessed a sharp decline in its share price, with intraday losses at one point surpassing 8%. By 10:18 a.m., the downturn had eased to a 3.69% drop, accompanied by a trading volume exceeding 2.3 billion yuan and a market capitalization that had dipped below the 50 billion yuan mark. Earlier, on October 8, Dongchedi unveiled a test video revealing that during an emergency braking test conducted on a closed track, where vehicles were brought to a halt from a speed of 100 km/h, the brake pedal brackets of three distinct batches of the new Zunjie V800 models all suffered fractures. This mishap left the vehicles incapable of braking normally, relying solely on the P-gear emergency brake for deceleration. The video's release promptly sparked a surge in social media discussions, with topics like 'Zunjie V800 brake pedal bracket fracture' trending rapidly.
