2012 Porsche Panamera Turbo S

If you own a Porsche Panamera Turbo and thought your car did not have enough horsepower, well, the car maker now has an answer . The 2012 Porsche Panamera Turbo S is coming to town.

The new Turbo S will be equipped with the same 4.8-liter V-8 engine as the Turbo, but the Turbo S will have new twin turbos with titanium-aluminum turbines that are lighter and more responsive. This new turbo system for the Turbo S boosts performance to 550-horsepower and 516 lb-ft of torque.

Exclusively for the Turbo S are the exterior side skirts and four-way rear spoiler, bi-color leather seats for the interior. Coming standard are the active anti-roll system ( PDCC), speed-sensitive steering, electronically controlled rear differential, and variable torque split for the rear axle.

The Turbo S will be in showrooms late spring. Expect to see a base price tag of around $174,175.
