(September 4, 2013) DETROIT — General Motors dealers delivered 275,847 vehicles in the United States in August, up 15 percent compared with a year ago. Retail sales increased 22 percent while fleet sales were down 8 percent.

Total and retail deliveries increased by double-digits at all GM brands. In total, Cadillac was up 38 percent, Buick was up 37 percent, GMC was up 14 percent and Chevrolet was up 10 percent.

Deliveries to retail customers were up 38 percent at Cadillac, 22 percent at Chevrolet, 16 percent at GMC and 24 percent at Buick. Buick’s retail sales were up for the 16th month in row, and it was the brand’s best August since 2003. Cadillac’s retail sales were the brand’s best August since 1989.

“The second half of 2013 is off to a very solid start for GM and our model-year change over and new product launches are going smoothly,” said Kurt McNeil, vice president, U.S. sales operations. “We have a lot of momentum and we feel good about the direction of the U.S. economy as we prepare to launch even more new products, including all-new heavy duty pickups and large SUVs for Chevrolet and GMC, a completely redesigned Cadillac CTS and the Chevrolet Corvette Stingray.”

GM’s sales last month were the highest of 2013 and the best since September 2008, when the global financial crisis began to accelerate. Two years later, on Sept. 8, 2010, Chevrolet launched the Cruze in North America, marking the beginning of an aggressive rollout of new products that will see nearly 30 Chevrolet, Cadillac, Buick and GMC nameplates either all new or redesigned by early 2014.
