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 62 mph to 50 mph in anticipation of the change of speed limit ahead. As you ease off the accelerator pedal, PDK deselects the current gear automatically and you begin to coast in neutral until you have reached your desired speed. As soon as you operate the accelerator or brake pedal, PDK re-engages the appropriate gear within fractions of a second. The process is smooth and seamless thanks to the extremely fast clutch.
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.
In short, driving in coasting mode makes a real impact on fuel consumption without any need for compromise on comfort or sporty performance.
