2010 Porsche Panamera 4S
Like most things Porsche, the 2010 Porsche Panamera 4S isn't easy to classify. At first, we were tempted to call it a squashed Cayenne, but the driving characteristics took that comparison out of the running. And although we were reminded of the 911 4S while behind the wheel, we just couldn't bring ourselves to call it a stretched 911.
No, Porsche came up with a unique new car that stands on its own in the model lineup. In broad strokes it takes its place among German flagship sedans such as the BMW 750i, the Mercedes-Benz S550, and the Audi A8, but the Panamera 4S's sport handling makes those other cars look like stately luxo-barges.
