Ahead of its Tokyo Motor Show-scheduled announcement, Porsche reveals the latest version to its luxury sports sedan in the Panamera Turbo S. Having already received a facelift for the 2014 year, the Panamera’s new performance model boasts a 4.8-liter twin turbo V8 engine that delivers 570 horsepower and 553 pound-feet of torque – both of which show an improvement from last year’s numbers. Despite the performance upgrade, Porsche has clocked the 2014 Turbo S at reaching 60 mph in 3.6 seconds – matching latest year’s time. Its top speed however is up two points reaching a lightning fast 192 mph. Additional features include carbon-ceramic breaks, 911 Turbo wheels, an exclusive new colorway, and so much more. Available in both a standard edition as well as a long-wheelbase Executive version, the Porche Panamera Turbo S is set to come with a price tag of $180,300 USD or $200,500 USD respectively, making it the most expensive and the most powerful Porsche you can buy after the 918 Spyder.
