Porsche upgrades it's 4 door super sedan, called the Panamera Turbo S with 550 HP pulling 0-60 MPH in 3.6 seconds with a top speed of 190 MPH.
Porsche will reveal its most powerful Panamera for on April 20, 2011 at the New York International Auto Show. Â The engine in the new top-of-the-line Panamera is has a maximum output of 550 horsepower and 553 lb-ft. Â An overboost function can temporarily generate additional torque with a peak rating of 590 lb.-ft.
Equipped with a PDK  transmission and launch control systems, the new Panamera Turbo S will hit 60 MPH from a dead stop in just 3.6 seconds making it arguable the quickest 4 door production car current manufactured.
The new 20-inch Turbo II wheels with increased rear axle track width, side skirts from the Porsche Exclusive range and the adaptive four-way extending rear spoiler express the car's elite performance abilities. Inside, the fusion of exclusivity and sportiness is conveyed in the interior by the standard bi-color leather finish. A new combination of black/cream is offered exclusively for the new Panamera Turbo S with Agate Grey/cream also being added as an exclusive option later this year. Agate Gray Metallic will also be an exclusive exterior color.
The new Porsche Panamera Turbo S starts at $173,200, although we expect them to be closer to $200k on the showroom floor after some options are added.
