All three Detroit automakers reported sales gains during the month of October, according to statements released by the companies.

Chrysler Group LLC reported the biggest year-over-year gain, posting a sales increase of 14% to a total of 122,565 units. It was the best November sales month since 2007 both for the company overall and the Ram Truck brand specifically; sales in the division rose 23%, to 24,337 units.  Sales of the Ram 1500 were up 24%, while Ram HD sales increased 26%, Chrysler said.

Ford Motor Co. reported an overall sales increase of 6% over year-ago levels, to a total of 177,673 units for the month. Sales of F-series trucks increased 18% to 56,299.

While sales of Chevrolet and GMC full-size trucks declined during November, parent company General Motors Co. posted an overall sales gain. For the month, the company’s four vehicle brands increased 3%, to 186,505 units. However, full-size pickup sales fell 8%, due in part to what GM described as “unexpectedly high competitive incentive activity,” which it did not match. Sales of the Chevrolet Silverado pickup fell 10.4%, to 30,674, while sales of the GMC Sierra slid 2% to 11,726.
