Fuel consumption* Cayman: Urban in l/100 km (mpg) 12.7 (22.2)-10.9 (25.9); Extra urban in l/100 km (mpg) 7.1 (39.8)-6.2 (45.6); Combined in l/100 km (mpg) 9.0 (31.4)-7.9 (35.8); CO2 emissions in g/km 211-183.
Efficiency is another area in which the performance of the Cayman models has been further improved. 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 100 to 80 km/h (62-49 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 with minimal input required on your part 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 utilise 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 motorway, 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 the need to compromise on comfort or sporty performance.
