Porsche has released details of the revised Panamera Turbo S ahead of the car’s official premiere at next month’s Tokyo Motor Show.
The range-topping four door, four seat Panamera model combines a power output of 570hp with an added level of dynamic and comfort-oriented features.
On the outside, the reworked styling includes a new front bumper with larger-sized air intakes as well as redesigned LED head lamps. The rear features an enlarged window set within the tailgate and a new bumper that now incorporates the licence plate.
Under the hood, the 192 mph saloon gets a 50hp increase in power compared to the Panamera Turbo engine, which has been achieved through specific revisions to a number of components. Two new turbochargers with larger compressors are fitted to the Turbo S, which increase the air flow and permit more air to be injected into the combustion chambers at high loads and engine speeds. In addition, the injection pressure has been increased by 20 bar to 140 bar. Together, both of these measures also enable higher component loads, and this in turn has been compensated by pistons made from a new aluminium alloy and specially coated piston rings.
This approach has two further advantages, claims Porsche. By preparing the air:fuel mixture in the combustion chambers more effectively, torque increases by 50 Nm to 750 Nm between 2,250 and 5,000 rpm, with the overboost increasing to 800 Nm. The extra torque makes the engine more responsive, such as when overtaking, for instance. The second enhancement is the fact that the New European Driving Cycle (NEDC) fuel consumption figures for the new model are the same as those of the Panamera Turbo at 27.7 mpg; which is an improvement of over 11 per cent versus the prior model.
In addition, individual cylinders are skipped when switching up a gear, allowing the engine speed to fall faster and the clutch to engage quickly. The reworked gear shifting strategy enables the Turbo S to accelerate from 0 to 62 mph in 3.8 seconds.
