After months of slowly releasingand , Porsche finally unveiled at the Shanghai motor show its first four-door sports car that can truly fit four full-sized adults.
The Panameras will be available with two engine options, a 400-horsepower, 4.8-liter V-8 and a 500-horsepower, twin-turbocharged version of the same block, according to an earlier CNET post, that goes from 0-60 in 4 seconds flat.
The Porsche is also standard-equipped with a PDK double-clutch transmission. In a nod to CAFE standards, the Panamera uses Start/Stop technology that turns the engine off when it's not needed, such as at stoplights or idling in traffic, and automatically restarts when the car needs to accelerate.
The 2010 Porsche Panamera will go on sale this October in the U.S., starting at $89,000 and up to $132,000 for the turbo model.
