Porsche Tops Off Panamera Line with Turbo S Model

Volkswagen AG's Porsche unit will show its fastest and most powerful grand touring sedan, the Panamera Turbo S, at the Tokyo auto show later this month.

Two new turbochargers with larger compressors on the 4.8-liter V-8 push Turbo S output to 570 hp and 553 lb-ft of torque, a 50-hp and 37 lb-ft increase compared to the standard Turbo model.

An overboost function allows torque to jump briefly to 590 lb-ft. The car's 0-60 mph time is 3.6 seconds, and top speed is 192 mph. All Turbo S models are equipped with all-wheel-drive and a 7-speed dual-clutch transmission.

A first-ever Executive stretched version of the Turbo S will be available with a wheelbase extended by 5.9 inches, resulting in more rear seating space.

The new model goes on sale early next year in the U.S. at $181,300 (Turbo S) and $201,500 (Turbo S Executive).
