Nov. 1 (Bloomberg) — Porsche AG, the world’s most profitable carmaker, said North American sales rose 21 percent in October, helped by new models of the Cayenne sport-utility vehicle and 911 sports car.

Deliveries in the U.S. and Canada increased to 3,018 cars and SUVs from 2,487 a year earlier, Stuttgart, Germany-based Porsche said in an e-mailed statement. Sales of the Cayenne surged 45 percent to 1,263 SUVs. The carmaker sold 1,017 of the 911, a gain of 38 percent. Demand for the Boxster and Cayman sports cars fell 16 percent to 738 vehicles.

Porsche, with the highest earnings as a proportion of sales in the car industry, gets more than a third of sales from the U.S. The company introduced the new version of the Cayenne in earlier this year in the U.S. and rolled out the Cayman, based on the Boxster, in 2005.
