Despite the subdued mood in China, Porsche delivered 4,821 vehicles to the region in August – an increase of 17.2% compared to the same month last year. In July 2015, Porsche had already gained ground with a growth of 6.2% despite the Chinese automotive economy cooling down. From January to August 2015, Porsche achieved an increase in deliveries of almost 38% in China.

The number of vehicles delivered world-wide rose in August 2015 by just under 20% to 17,893 compared to the same month last year. During the course of the year, world-wide deliveries totalled 152,610 vehicles, a rise of 27.4%.

"[China] is on the path to normality. We are expecting further growth. But the end of high dynamic growth has been reached for the time being," said the automaker's sales and marketing chief Bernhard Maier. "China is and remains a key market for Porsche. Just as important for us are the USA and Europe."

In August 2015, 5,008 new cars were delivered in the United States, a rise of 10% in the most successful single market that month.

Sales in Germany and Europe brightened up the rising uncertainties about China's economic future. Porsche delivered 13.6% more cars in Germany and 35.7% more in Europe compared with the same month last year.

Maier remained cautiously optimistic. "We are pursuing our aims prudently and with all the necessary respect in view of the highly volatile global economy. For us this means that qualitative growth is the barometer of our success, not only the registration figures. Our focus is definitely on ROI and employment."
