Thanks Ed, good comments. Having owned both Ferraris ( a Daytona for example) and many Porsches, I understand the different philosophies and products of each company. In the past, I would have ureservedly agreed that a Porsche will always be a Porsche and a Ferrari a Ferrari.
But with the Panamera--along with Porsche's product expansionist philosophy and financial success--I think Porsche is moving very close to the 599 segment. And this does not mean that "Porscheness" will be lost. Porsche could well produce a Panamera Turbo S, with many luxury appointments and special bodywork as standard, that could cost well over $200,000 and be within range of the 599, Scaglietti, or Mercedes AMG CLS 65 twelve cylinder turbo. It would retain its "Porscheness" with its turbocharged powerplant, clean design elements, unexcelled handling, and race-bred technology.
If I were Ferrari or Maserati, I would be on the alert. Then Porsche would be offering sport cars throughout virtually every market segment. My guess is that sort of reach is top level management's dream about to come true...
