Porsche Panamera Turbo Gets 50 More Horsepower
The new Panamera Turbo S is also perfectly equipped to effectively convert its increased level of power and torque into sporty driving dynamics. One of the requirements for this effective conversion of power is the Porsche Traction Management (PTM) all-wheel drive system, which optimizes torque flow to the wheels, even in difficult driving conditions. The Sport Chrono package comes as standard, and coordinates the drive power and chassis at the touch of a button to guarantee a consistently sporty response. The overboost function is activated in “Sport” and “Sport Plus” mode as well as during kickdown in “Normal” mode; the overboost function temporarily increases the boost pressure to enable even more powerful acceleration capability. The “Launch Control” start function guarantees the best possible acceleration when moving off by optimally co-ordinating the responses of the engine control system and the Porsche Doppelkupplung gearshift program. Thanks to the reworked gear shifting strategy, the Porsche Doppelkupplung changes between its seven gears even more rapidly, accelerating the new Panamera top model from 0 to 100km/h in 3.6 seconds.
However, what is more interesting about this super sedan is that it has a 50-hp increase in power compared to the Panamera Turbo engine. This has been achieved through specific revisions to a number of components. Porsche is now using two new turbochargers with larger compressors in the Panamera Turbo S model. The new compressors increase the air flow, and the chargers push more oxygen into the combustion chambers at high loads and 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, which are absorbed by pistons made from a new aluminium alloy and specially coated piston rings.
This concept has two further advantages: By preparing the air-fuel mixture in the combustion chambers more effectively, the torque also increases to 553 lb.-ft. at between 2,250 and 5,000 rpm, with overboost increasing torque momentarily to 590 lb.-ft. The extra torque makes overtaking even easier and faster.
Thanks to the optional sport exhaust system, the Panamera Turbo S offers drivers the opportunity to maximize the emotional character of the car whenever they wish. This unique sound experience is achieved by means of an acoustic channel that can be switched at the push of a button; this channel directs the engine sound straight into the interior. In addition, individual cylinders are skipped when switching up a gear, allowing the engine speed to fall faster and the clutch to engage quickly.
