2010 Porsche Panamera 4S (photos)

There was a time, in the mid-1990s, when Porsche was down to just two models in its lineup. This decade the company is showing new energy, coming out with an SUV, a new sports car, and now a hatchback sedan. The Panamera represents a new and potentially lucrative direction for Porsche as it competes with big luxury sedans from BMW, Audi, and Mercedes-Benz.
