Porsche has released this new video of its Panamera Turbo S model. The latest in the Porsche saloon line-up is equipped with a 4.8-litre V8 twinturbo engine with 550 hp and 750 Nm of torque. The overboost function provides another 50 Nm. If anyone thought that a four-door Porsche sedan meant compromising on Porsche sports performance, the 3.8 seconds to 100 km/hr and top speed of 306 km/hr of the Panamera Turbo S has surely changed their minds.
