As rumored, Porsche has revealed a new Panamera Turbo S model as the new highest-performance sedan in the sports car maker's range. With a 10 percent increase in power (50-hp) the Turbo S now delivers 550-hp from its twin-turbo 4.8-liter V8 engine with torque increasing from 516 lb-ft to 553 lb-ft. Plus, in the Sport and Sport Plus modes or during full throttle in the regular driving mode there's a solid 590 lb-ft on tap. That added power comes from a retuned ECU, plus lighter titanium-aluminum turbine compressor wheels, that also aid responsiveness.
With launch control, Porsche claims a 0-60 mph time of 3.6 seconds and a top speed of 191 mph.
Setting the Turbo S apart on the road is an even wider rear track with new 20-inch Turbo II wheels, plus special Porsche Exclusive side skirts and a rear spoiler. Inside, all models come with a two-tone leather finish with a new black and cream combo offered exclusively on the Turbo S.
