Porsche is planning to spend $200 million to extensively improve its Weissach R&D center. Upgrades include an advanced wind tunnel, a more spacious design center, and an electronics integration center. A major focus of the facility upgrades is to help the automaker increase the energy efficiency of its future vehicles. Company executives said Weissach's improvements are urgently required and include siting key suppliers' engineers closer to their Porsche counterparts. "This spatial proximity is a major advantage," said Wolfgang Durheimer, Porsche AG Board of Management Member for Research and Development. "The close interaction of our suppliers' various electrical system/electronics experts and colleagues from related specialist fields during development will contribute significantly to the success of our work, particularly in the case of electronics, which now play a role in virtually every vehicle component." Porsche also will recruit approximately 100 engineers during the first stage of Weissach's upgrades, according to the company.
