Thermal management

The Boxster models feature a new version of thermal management to reduce friction losses that arise during the warm-up phase.

Thanks to the selective 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.

Our cross-flow cooling system, as used in motorsport, supplies each engine cylinder uniformly with coolant, which protects the valves against thermal overload and, therefore, premature wear. This improves combustion and keeps emissions, fuel consumption and noise comparatively low.

Auto start/stop function

The auto start/stop function, which is 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.

The auto start/stop function can be deactivated and reactivated using a separate button on the centre console. The function may be deactivated automatically under particular circumstances, for example in extreme outside temperatures, when the SPORT button is selected or when there is low battery charge.

Electrical system recuperation

For enhanced efficiency the Boxster models are equipped with intelligent 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.

Fuel consumption* Boxster: 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.
