The auto start/stop function still works in the familiar way. As soon as you come to a halt and keep your foot on the brake pedal, the system will automatically stop the engine. This fuel-saving system restarts the engine the moment you release the brakes.
What’s new, however, is that the engine now switches off as you approach traffic lights. All audio and communication systems remain switched on and the climate control continues to maintain your selected temperature, despite the engine being switched off. The engine restarts automatically if the energy needs of the auxiliary equipment can no longer be met by the energy saved in the battery. In all models (except the Panamera S E-Hybrid), the auto start/stop function can be activated and deactivated using a separate button.
