New model from Porsche: Four-Door Panamera

Porsche Panamera described as a four-door grand touring (GT) sports car rather than a coupe or sedan. Production is slated to start next spring for a summer on-sale date, and the car is expected to be priced at around $175,000.

Power for the Panamera will come from a range of V6 and V8 engines that will likely mirror the Cayenne lineup. The engines will run from a paltry 300 horsepower up to the 500-hp unit from the Cayenne Turbo.
