Porsche has rolled its new Panamera Turbo S into the Jacob Javits Center for the start of today's New York Auto Show, offering us our first live view of the new range-topping sedan. As we told you last month, the four-passenger Porsche boasts the same twin-turbocharged 4.8-liter V8 as the standard Cayenne Turbo model, but new turbochargers (with titanium–aluminum turbines) and some engine remapping bumps output to 550 horsepower and 553 pound-feet of torque. When the driver selects "Sport" or "Sport Plus" mode (the Sport Chrono package is standard), the ECU will allow overboost to 590 pound-feet of torque. With standard all-wheel drive, Porsche says the Panamera Turbo S will sprint to 60 mph in just 3.6 seconds (knowing Porsche, that's conservative) and deliver a terminal velocity of 190 mph.
In addition to the new "S" scripting on the rear hatchback, the flagship model is differentiated by new 20-inch Turbo II wheels (with increased rear axle track width) and standard side skirts pulled from the Porsche Exclusive options list. The interior features standard bi-color leather upholstery (black/cream is an exclusive Turbo S combo) and Agate Gray Metallic is a new exclusive exterior color. Base price of the world's quickest sedan is $173,000 (plus $975 delivery and destination). The Porsche Panamera Turbo S goes on sale this Spring.
