Thanks to the selective heat flow control strategy and on-demand, gradual activation of the various cooling circuits, the engine and gearbox warm up to normal operating temperature more rapidly. The consequent reduction in friction also reduces fuel consumption and CO2 emissions. During sporty driving, thermal management also acts to reduce temperatures so that a high level of performance is maintained.
The auto start/stop function, integrated as standard in the Boxster models, switches off the engine when you stop, select neutral and release the clutch pedal. In cars with Porsche Doppelkupplung (PDK), it is simply a case of applying and holding the brake. All audio and communication systems remain switched on.
The engine will restart as soon as you operate the clutch or, in cars with PDK, release the brake. This fuel-saving innovation is designed primarily for use in towns or congested motorway traffic.
Another efficiency-enhancing function in the Boxster models is electrical system recuperation. The vehicle battery is recharged by the generator predominantly under braking. Thanks to this selective recharging, when you request full driving power the maximum possible output can be directed straight to the road.
The electronic engine management system ensures optimum engine performance at all times. It regulates all engine-related functions and assemblies. The results are optimum power output and torque with comparatively low fuel consumption and emissions.
