Porsche has unveiled more information and specifications about its upcoming Cayenne S Hybrid. The automaker plans to employ a parallel electric motor that's capable of powering the SUV at speeds up to 86 mph all by itself, without clicking on the gasoline engine. That's far faster than the upcoming third-generation Toyota Prius and Ford Fusion Hybrid, the two leaders in that category, can travel on electric power alone. As with those cars, the Cayenne S Hybrid can't necessarily accelerate to that speed without utilizing both engines. But it can roll freely, or coast, giving the Cayenne S Hybrid an advantage in situations other than low-speed city traffic, where hybrids usually excel.
