General Motors' US sales up 19 per cent in September on strong truck demand

DETROIT - General Motors' U.S. sales jumped 19 per cent in September on big demand for its pickup trucks.

GM's sales totalled 223,437 cars and trucks. Three of its four brands saw double-digit gains; Cadillac sales were flat compared with last September.

Sales of the Chevrolet Silverado pickup rose 54 per cent to 50,176, while the GMC Sierra pickup was up 25 per cent to 16,763.

GM's SUV sales were also strong. Cadillac Escalade sales more than doubled, while Chevrolet Traverse sales rose 45 per cent.
