The coasting function available with Porsche Doppelkupplung (PDK) enables you to save even more fuel where the situation allows. The engine is decoupled from the transmission to prevent deceleration caused by engine braking. In this way, optimum use is made of the vehicle’s momentum, allowing it to coast for longer distances.
For example, you may want to slow down from 60 mph to 55 mph in anticipation of the change of speed limit ahead. As soon as you release the accelerator pedal, PDK automatically deselects the current gear and you begin to coast in neutral until you have reached your desired speed. The moment you engage the accelerator or brake pedal, PDK selects the appropriate gear smoothly and seamlessly within a fraction of a second.
Another way to reduce fuel consumption is to utilize the coasting function on downhill gradients that are gentle enough for you to maintain a constant speed. Efficient on long journeys, such as on the highway, PDK remains ready to respond as swiftly and precisely as you would expect.
