"While most other plug-in hybrids are primarily about the “green” aspect of the system, Porsche uses it for performance as well, providing a considerable boost to the gasoline engine. For this reason, the engine’s power can be used to recharge the battery, especially in Sport-Plus mode. When set into this mode, the engine not only charges the battery very quickly but also drinks deeply from it to maximize what happens when you hit the go-pedal. This isn’t about planet-saving because this mode uses as much fuel as you’d expect – but hey, it’s a Porsche."
