Porsche on Monday said it is reorganising its participation in trade fair activities in North America, in collaboration with its Atlanta, Georgia-based sales company, including withdrawal from the annual Detroit motor show.

"As part of the general reduction in trade fair appearances which began two years ago, in favour of greater emphasis on direct contact with potential customers, motor show activities will in future be concentrated in the main sales areas of Porsche Cars North America (PCNA)," the luxury sportscar and SUV maker said in a statement.

"Of the North American trade fairs in 2008, Porsche will among others be attending those in Chicago, Los Angeles, Miami, New York and Toronto.

In a move that may surprise industry observers, Porsche added: "The company is no longer expected to attend the North American International Auto Show in Detroit."

Explaining its decision, Porsche said: "As a successful supplier of sporty premium vehicles, Porsche is an exclusive niche manufacturer in the USA and Canada, just as it is elsewhere.

"Despite consistently achieving record sales figures, Porsche constantly strives to use its limited resources in the most efficient, customer-oriented manner possible.

"Of the 36,669 vehicles delivered to customers in North America by Porsche during its record 2005/06 fiscal year, over 20,000 were destined for the west and east coasts.

"These results go to show that the restructuring of trade fair activities was a strategic company decision that is bearing fruit."
