Porsche, which runs its business from August to July, said in a statement that it sold a total 25 635 cars worldwide in the four months to November, 8.5% more than in the same period a year earlier.
That brought turnover up by 6.7% to 2.02 billion euros (2.4 billion dollars) in the four-month period, the car maker said.
"Once again our sports cars are driving growth," Porsche said.
The car maker sold 9 439 of its 911 model, 11.4 percent more than in the year-earlier period.
A total of 4 998 Boxsters, including the new Cayman S, were sold, representing an increase of 179% year-on-year.
By contrast, the Cayenne sports utility vehicle (SUV) was sold a total of 10 974 times, down 16.7% on the year. And sales of the Carrera GT rose by 14.9% to 224 units.
Overall output was up 11.1% at 29 895 cars in the August-November period.
"Despite the economic imponderables, we are confident with regard to the outlook for the remainder of the year, since all three model series are enjoying lively demand," Porsche said.
It was therefore expecting further growth during the current year.
