DETROIT (TheStreet) -- Five years into a slow economic recovery, auto sales continue to show surprising strength, with Chrysler and Ford (F) - Get Report  estimating that industry sales for August will gain 3%, despite widespread projections that sales would be flat compared with a year earlier.

Chrysler also said the seasonally adjusted annual sales rate for August is expected to reach 17.4 million units, the year's highest level, while Kelley Blue Book said new car transaction prices rose nearly 3%. GM (GM) - Get Report said on Wednesday that full-year light vehicle sales are expected to be near the high-end of its January outlook, which was for sales of 16 million to 16.5 million.

Ford sales totaled 221,174 vehicles, the company's best August in eight years. "Both Fusion and Escape set records in August, each continuing on a strong pace toward 2014 being a best-ever sales year," said John Felice, Ford vice president, U.S. marketing, sales and service, in a prepared statement.

Sales of the F-Series pickup truck, the best-selling U.S. vehicle, fell 4.2% to 68,109 units. Fusion sales rose 19% to 29,452. Escape sales rose 9% to 28,996.

GM delivered 272,423 vehicles in August. Silverado sales gained 13% to 49,201. But Chevrolet sales fell 1% to 185,930, with Cruze, the top GM car, down 2% to 23,435. Buick sales fell 10% to 22,143 while Cadillac sales fell 18% to 16,650. Retail sales fell 4%, while fleet sales gained 9%.

GM said its incentive spending as a percentage of average transaction prices was 10.4%, the lowest of all domestic automakers by a significant margin.

"We see a strong fall selling season ahead for GM and the industry, which sets the stage for the launches of the Chevrolet Colorado and GMC Canyon," said Kurt McNeil, U.S. vice president of sales operations, in a prepared statement. "Car-buying fundamentals like employment and energy prices are in good shape, consumer confidence has reached a post-recession high and business investment is increasing."
