The 2014 Panamera facelift lineup is now complete with the Turbo S joining the standard model, Turbo, and E-Hybrid variants. Thanks to a reworked engine that includes new turbochargers and pistons, the facelifted model receives a 20 hp boost, taking the 4.8-liter twin-turbo V8 to 562 hp - 49 hp more than the Turbo. Torque remains at 553 lb-ft, but can be boosted to 590 lb-ft for short bursts of full throttle acceleration. 0-62 mph is unchanged at 3.8 seconds, top speed creeps up from 190 to 193 mph, while economy improves by 11 percent.

Set for a public debut at the Tokyo Motor Show, the range-topping Panamera sports similar styling upgrades as its less powerful siblings, and comes with a new front bumper with larger air intakes and redesigned LED headlamps. At the back, a larger window is stretched within the tailgate, the new bumper now houses the license plate and Porsche has added a color-keyed four-way spoiler. Porsche is now offering the Panamera Turbo S in Executive form, which receives a 150 mm longer wheelbase for a roomier cabin. 20-inch 911 Turbo-style alloys come as standard on both models. Porsche has priced the Panamera Turbo S from $180,300, and the Turbo S Executive from $200,500.
