Preliminary results for the latest fiscal year ended 31 July showed Porsche grew turnover 17.9% to EUR7.79bn on unit sales up 8.8% to 81,850.

“The record turnover dramatically demonstrates that Porsche has regained its former strength," outgoing chairman Michael Macht said in a statement. He expects more growth following the launch of the 911 Speedster and Carrera GTS at the Paris show this week.

The Cayenne remained Porsche's best selling line at 29,855 units, down 12.9% due partly to the spring model changeover.

Sales of the 911 "were negatively affected by the continuing difficult economic conditions facing the sports-car market", Porsche said, explaining the 27.4% fall to 19,663 units. Boxster sales dipped 10.8% to 11,717 units..

Sales outside Europe and North America grew 25.8% to 25,283 vehicles and China alone took 11,724 units, up 47.5%.

Europe sales rose just 1.4% to 30,948 units with German volume off 3.5% to 11,857. North American sales rose 4% to 23,705 vehicles.

Fiscal year production was up 16.1% to 89,123 vehicles.
