Porsche squeezes more power out of the 4.8 liter bi-turbo V8 of the Panamera Turbo for this new range-topping S variant.

Porsche has announced the new Panamera S Turbo.

The news comes a little earlier than expected, as we reported yesterday that an unveiling at either the New York or Shanghai auto show was coming. The Panamera S Turbo will likely be presented at both those shows now.

The numbers make this Panamera worthy of a new title - the Turbo S now produces 550 PS (405 kW / 542 hp) and 800 Nm (590 lb-ft) of torque with overboost (750 Nm / 553 lb-ft without). The same 4.8 liter bi-turbo V8 produces 500 PS (368 kW / 493 bhp) and 700 Nm (516 lb-ft) on the standard Panamera Turbo model.

The Panamera Turbo S does the 0 to 100 km/h sprint in 3.8 seconds and reaches a top speed of 306 km/h (190 mph).

The power boost was achieved by means of new titanium-aluminum turbines for the bi-turbo system and an optimized engine management.

Porsche has also kept an eye on fuel-economy with the Panamera Turbo S which has a consumption rating of 11.3 liters/100 km when fitted with specially-designed 19-inch rims and low roll-resistance all-season tires from Michelin. Porsche also offers 20-inch wheels on the model.

Standard on the Panamera Turbo S is the Porsche Dynamic Chassis Control (PDCC) and the Sport Chrono Package Turbo.

The Panamera Turbo S is priced at €167,076 in Germany, including VAT, with deliveries beginning as of June.
