From September customer's choice will expand when purchasing the Porsche Panamera Turbo as customers can then specify the new Powerkit which raises engine output by 40 hp to 540hp. The key elements of the Porsche Panamera Turbo Powerkit are two new turbochargers with titanium alloy turbine wheels. The engine management computer has been adapted and the result is an appreciable further improvement in the engine's responsiveness. Maximum torque rises to 750 Nm from 700 Nm. When the Sport Chrono package is combined with the Powerkit, torque increases in the over-boost mode to 800 Nm.
In Sport Plus mode, the Porsche Panamera Turbo with Powerkit accelerates 0.1 sec faster than the standard car, reaching 62mph from rest in 3.9 sec. Top speed is 190mph (305 km/h) compared with 188mph (303 km/h). However, by returning 24.6 mpg (11.5 ltr/100 km) during the NEDC test cycle, fuel consumption of a Porsche Panamera Turbo with Powerkit is the same as that of the 500 hp version, a perfect demonstration of Porsche Intelligent Performance.
The Powerkit will be available from September 2010 at a price of £11,118 including VAT. Porsche Tequipment will launch the Powerkit as a retrofit kit from November.
