Basically, PDK is an dual mode (automatic & manual) double clutch system. In an ordinary single clutch transmission, when the gears shift there is a lag in acceleration as the single clutch releases the current gear and closes on the next gear. In the PDK 7 gear transmission, as one clutch opens on the current gear, simultaneously the other clutch closes on the next gear, allowing nearly seamless gear changes in milliseconds.

PTV (Porsche Torque Vectoring) 911 Turbo
PTV provides variable torque distribution to the rear wheels along with mechanical limited slip-differential. This technology very simply means that when the vehicle is cornering, the system applies moderate braking to the inside wheel and more power to the outside wheel giving the car greater stability through the turn.

The Boxer Engine which has long been the traditional engime design at Porsche is characterized by two banks of cylinders facing each other at a 180 degree angle as opposed to the V configuration typically found in American muscle cars. The name comes from the pistons moving simultaneously like a boxer punching their firsts together before a fight.
Mid-Engine - Boxster & Cayman
In mid-engine cars the engine is placed in front of the rear axle, towards the middle of the car. Doing this, places the vehicles center of gravity closer to the center of the car which means...better cornering! Click here to see a diagram.
PTM (Porsche Traction Management) All wheel drive models
This all wheel drive traction control system utilizes an electronic multi plate clutch allowing the transmission to provide more drive force to the axle that has the greatest amount of traction. If the rear wheels are about to spin due to overacceleration, the system distributes more traction to the front wheels. For a more detailed explanation, click here.
