Porsche has confirmed on Wednesday that it will build the Porsche 918 Spyder, initially gone public earlier this year as a concept at the 2010 Geneva Auto Show. The German automaker said the production version of the high-performance hybrid will be assembled in limited numbers at its home plant in Zuffenhausen, just outside Stuttgart. An official statement released Wednesday said the company has received an "overwhelming response" from the public to the Porsche 918 Spyder concept. Earlier reports indicated Porsche had received expressions of interest from more than 900 buyers. Porsche did not specify a production start-up date or a price tag, although widespread media reports in Europe have suggested the sticker could exceed $600,000.
