The Panamera will compete with flagship cars such as the Mercedes-Benz CLS, the Bentley Continental Flying Spur and whatever BMW decides to do with the CS concept it showed at the Shanghai auto show earlier this year. Promising sports-car handling in a roomy sedan body, the Panamera will be all Porsche, at least according to the company. Its strong family resemblance to the rest of the line speaks well, even if the resulting hodgepodge is not exactly beautiful. Still, we admit the Cayenne’s performance floored us, and we have similar hopes for the Panamera.
