A quick look at 28 new luxury vehicles to watch out for in 2010

2010 Porsche Panamera
With the world used to the idea of a Porsche sport utility, the company is shocking our senses once again with the Panamera sedan. Looking like a stretched 911 with an extra pair of doors -- or a squashed Cayenne -- the Panamera may not be everyone's favorite car to see. But with nearly 500 horsepower and a seven-speed automated manual, the Panamera promises the kind of performance we expect from the German sports car maker. The Panamera will go up against new "four door coupes" from Aston Martin and Audi, as well as existing players like the Mercedes-Benz CLS and Maserati Quattroporte. It might just eat them alive.
