2011 Porsche Panamera 4

The Panamera is Porsche's big four-door hatchback, a sports car with room for four that competes with the Audi A7 and the Mercedes CLS. It drives like a Porsche, with sharp steering and a planted feel that makes it surprisingly nimble for its size. Inside, the cabin is upscale and comfortable, and the back seat is genuinely roomy, so four adults can ride in comfort. Owners love the space and the sound system, but they warn that maintenance and winter driving can be challenges. Its 3.6L V6 makes 300 horsepower and pairs with the quick-shifting seven-speed PDK, returning 21 mpg combined. Standard steel springs give a firm ride, but the 4's all-wheel drive makes it a more confident choice in rain or snow than the rear-drive S.
