DETROIT ( TheStreet) -- General Motors said its sales rose 10.7% in June and sales of its four core brands rose 36%. At the same time, overall GM sales dropped about 13% from May to June. Moreover, GM's June 2009 sales provide a weak comparison as the automaker was preparing to enter bankruptcy. TrueCar.com has estimated that industry sales will rise 14.5% over June 2010, but decline 10.5% from May.
Still, even as the economy is slowing, it appears that GM has been successful in retaining market share despite a reduction from eight brands to four. Year-to-date sales of the four brands -- Chevrolet, Buick, GMC and Cadillac -- are up 32%. Buick sales were up 53% from a year earlier, while sales of the Chevrolet Silverado rose 25%. GM said its June performance was fueled by the success of launch vehicles, increasing crossover sales and some recovery in markets for pickups and full-sized SUVs. GM sales totaled 195,380, including fleet sales of 59,571 vehicles. According to TrueCar.com, Ford ( F) sales are expected to decline 10% from May and to increase 17% from June 2009. -- Written by Ted Reed in Charlotte, N.C.
