The Porsche Panamera is a four-door, four-seater luxury sedan launched in 2003. The car has an engine at the front and rear or all-wheel drive. The Panamera is marketed as a sedan, but technically it is a five-door hatchback with wide-opening tailgate. This Porsche will compete directly with cars such as the Mercedes-Benz CLS63 AMG, Aston Martin Rapide, Lamborghini Estoque and Maserati Quattroporte and will compete in part with the more expensive Bentley Continental GT and Ferrari 612 Scaglietti. Initially, the Panamera will have three engines - a 3.6 L V6 with 300 hp (224 kW), a 4.8 L V8 with 405 hp (302 kW) and a turbo version with a 4.8 L V8 engine with approximately 500 hp (373 kW).
