      <p>PDK is available as an option for the 911 Carrera GTS models. Gear changes take place in milliseconds, for vastly improved acceleration and lower fuel consumption. </p>
      <p>In total, PDK has seven gears at its disposal. Gears 1 to 6 have a sports ratio, with the top speed being reached in 6th gear. The 7th gear has a long ratio and helps to reduce fuel consumption even further. PDK is essentially two half gearboxes in one and thus requires two clutches – designed here as a double wet clutch transmission. </p>
      <p>This double clutch provides an alternating, non positive connection between the two half gearboxes and the engine by means of two separate input shafts (input shaft 1 is nested inside the hollowed-out input shaft 2). The flow of power from the engine is only ever transmitted through one half gearbox and one clutch at a time, while the next gear is preselected in the second half-gearbox. During a gear change, therefore, a conventional shift no longer takes place. Instead, one clutch simply opens and the other closes at the same time. </p>
      <p>PDK and the manual gearbox deliver power directly to the road. With the optional Sport Chrono Package Plus, you can make it more direct, and sportier. With a rush of adrenaline and euphoria, you are straight into the action.</p>
