Porsche gave shareholders a return of 3.2 percent in the quarter.
The company last month said sales were heading to an all-time high. During the first 10 months of its current fiscal year ending July 31, sales increased 13.3 percent to a total of 69,685 vehicles, mostly on successful launches of new-generation sports cars.
"The rejuvenation of Porsche's product lineup with new 911 and Boxster models is already boosting group sales," said Philip Wylie, automotive leader at Pricewaterhouse-Coopers corporate finance. "The launch of the Cayman coupe in the autumn is expected to have a positive impact on both its financial results and share price over many years."
On June 9, the 100,000th Cayenne SUV rolled off the production line at Porsche's Leipzig, Germany, factory, where capacity utilization remains at maximum.
BMW's shareholder return rose 2.6 percent in the quarter. Unit sales in the first quarter reached a new high of 292,207, up 8.2 percent from the same period in 2004. Mini sales rose 10.3 percent to 52,694.
But BMW sales revenue for the quarter fell 4.1 percent to E10.36 billion. That partly reflected the weakness of the dollar against the euro, which reduces earnings made in North America when translated into euros.
However, the company's decision to buy back part of its shares, effectively an extra dividend, cheered investors.
Trouble by association
In contrast, DaimlerChrysler's shareholder return declined 5.2 percent.
"The troubles of Ford and GM have reverberated onto D/C," PwC's Wylie said.
To bolster its market share, Chrysler has had to increase incentives to compete with Ford and GM.
But Wylie is optimistic about D/C's prospects.
"The Ford and GM downgrading should provide DaimlerChrysler with a competitive advantage against its two rivals," he said, "in terms of image and funding costs."
Total Shareholder Value Index
The Automotive News Europe/PricewaterhouseCoopers Shareholder Value Index for European automakers, suppliers and retailers reflects investor returns for publicly traded companies.
The index measures the growth in value of an investment by including capital gains, share buybacks and dividends, and assumes that all cash distributions are reinvested.
The three categories surveyed include vehicle manufacturers headquartered in Europe; European suppliers with annual sales more than E100 million, of which more than 50 percent is in the automotive sector; and European car retail companies with sales more than E250 million. The returns have been adjusted for currency movements.The indices are weighted by market capitalization. Companies with larger capitalization - the value of a share price multiplied by the number of shares outstanding - have a greater impact on the index.
