Porsche says it has achieved growth in deliveries, revenue and profit in the first quarter. In the quarter ended 31 March, Porsche delivered 51,102 new cars - 32% more than in the same period last year. Revenue in the first three months of 2015 increased 29% to EUR5.08bn and operating profit surpassed the previous year's figure by 10% at EUR765m.

Porsche also said the number of employees was up 12% to 22,945.

Porsche said a key factor behind the increases was the incremental impact on sales of the new compact SUV Macan, which was introduced last year and will be available for a full 12 months for the first time in 2015. Other highlights, the company said, are new versions of existing models. These include the GT models - the 911 GT3 RS and Cayman GT4 - as well as the Boxster Spyder and the Panamera Exclusive. "Our successful vehicle derivatives strategy lets us satisfy the wishes of many customers who want to own a comprehensively personalised vehicle," said CEO Matthias Müller.

CFO Lutz Meschke drew attention to the company's continuously high profitability. "The first quarter result of 765 million euros reflects our healthy cost structure and the high profitability of Porsche," he said. In light of present currency trends, Lutz Meschke is also optimistic that "with regard to the full fiscal year, we will reach last year's profit at a minimum. We will continue to hold to our strategic returns target of 15 per cent."

Porsche also said that research and development costs have nearly doubled at Porsche over the past three years, "in particular due to expenses for alternative drives". In the current year, research and development costs will once again run at around 9-10% , said Meschke.
