December Auto Sales: General Motors

DETROIT (AP) -- General Motors Co. said Friday that its December U.S. sales fell 6 percent as its top-selling pickup truck came under pressure from discounts by competitors.

TOP SELLERS: Chevrolet Silverado sales fell 16 percent to 42,593. But Chevy Malibu midsize car sales rose 33 percent to 15,493.

HOT MODELS: Cadillac ATS small sports sedan, up 31 percent to 3,887. Redesigned Chevy Corvette muscle car sales more than doubled to 3,005.
