The leading U.S. automaker, General Motors Co., on Tuesday announced that it sold a total of 186,895 vehicles in October, up two percent from the same period of last year. The brand breakdown showed that GM\'s best-seller Chevrolet rose six percent in the month, while GMC, Buick and Cadillac all suffered contraction. Don Johnson, vice president of U.S. Sales Operations, said that Chevrolet led the way for GM in October driven by the continued success of the Cruze and Equinox. Besides, the launches of several new fuel-efficient cars would well position the company going forward. In October, the retail sales, which accounted for 77 percent of GM\'s total sales, increased three percent from a year earlier, while the delivery for fleet customers was essentially unchanged. Besides, GM\'s year-over-year passenger car sales increased four percent, crossover sales decreased one percent, and sales of trucks, which include full-size pickups, vans and SUVs, increased two percent.
