General Motors' China sales growth dropped to 0.7 percent in the second quarter from 8 percent in the first quarter because of a slump at Buick.
GM and its two joint ventures delivered 858,344 cars and light trucks in China during the second quarter.
During the latest three-month period, Buick deliveries fell 16 percent from a year earlier to 230,454. The decline largely offset gains at GM¡¯s other brands.
Cadillac¡¯s second-quarter deliveries jumped 19 percent to 48,712 on robust demand for the XTS and CT6 sedans.
Chevrolet sales advanced 22 percent to 131,895, reflecting strong demand for the Malibu and Cavalier sedans and the Equinox crossover.
During the period, deliveries of the Baojun market-entry brand increased 6 percent to 198,986 on demand for the 310 sedan and the newly launched 360 multi-purpose vehicle.
Sales at Wuling, China¡¯s largest minibus maker, also rose 3.1 percent to 248,297, led by the brand¡¯s first SUV -- the Hong Guang G3.
SAIC-GM, GM¡¯s passenger vehicle with SAIC Motor Corp., produces and sells Cadillac, Buick and Chevrolet models.
