2010 Porsche Panamera

Porsche ticked off the sports car purists years ago with the Cayenne SUV, so the four-door Panamera sedan is no big deal. Although the hatchback body style gives the car a slightly awkward rear, there isn't much else to bemoan. The 4.8-liter V-8 makes 400 hp and 369 lb-ft. of torque in S and 4S spec, or a bracing 500 hp and 516 lb-ft. of torque in the Panamera Turbo. Imbued with Porsche's industry-leading chassis control system technology and PDK dual-clutch transmission, there is nothing watered down about the Panamera driving experience. Of course, if it were diluted, it would be with chilled Perrier, since the Panamera offers an optional rear seat refrigerator unit.

Why we're thankful: Porsche stays true to its roots while expanding the brand
