Just like the Cayenne, Porsche Panamera too gets a range-topping Turbo S model. The four-door Gran Turismo is powered by a tweaked version of 4.8 litre V8 biturbo engine which now delivers 550 hp (410 kW) and 750 Nm of torque.

That is 50 more hp and 50 more Nm over the standard Turbo. The extra power is achieved by using improved turbochargers with titanium-aluminium turbine wheels and modified engine control. It also has an overboost function that engages at kick-downs, or in the “Sport” and “Sport Plus” mode of the standard Sport Chrono Package.

This big luxury sedan also comes with Launch Control feature that enables it to go from zero to 100 km/h in just 3.8 seconds and reach a top speed of 306 km/h (191 mph). That is an astonishing record for such a gigantic and seemingly heavy car. Despite the extraordinary performance, Panamera Turbo S has an NEDC average fuel consumption of 11.5 liter per 100 km (25 mpg). That can be lowered to 11.3 using the new 19 inch, all-season tyres with optimised rolling resistance developed for the Panamera by Michelin.

As you expect the car is also packed with a great number of electronic controlling system such as Porsche Dynamic Chassis Control (PDCC), Sport Chrono Package Turbo or Porsche Torque Vectoring Plus (PTV Plus), to name a few. Other changes over normal Turbo models include 20-inch Turbo II wheels with increased rear axle track width, side skirts from the Porsche Exclusive range and the adaptive extending four-way rear spoiler in the exterior colour. The new combination of black/cream is offered exclusively for the new Panamera Turbo S with agate grey/cream also being added as an exclusive combination from the autumn.

This is obviously the best version of the Panamera, even though it costs a whopping 167,076 euro in Germany. But the main problem with it is still the way it looks. We wish Porsche spends a bit less time in the engineering department and a bit more in design.
