If you know your physics, you know the faster a flywheel spins, the more energy it stores. As that energy is released as torque, its speed reduces. Applying that principle, one engineering student slapped one on a bicycle as an energy booster.
Before Porsche builds a handful of its 918 Spyder plug-in hybrids, it has to finish the production bodywork, which it teased today as part of an expansion of its research labs, which cost the equivalent of 250 Porsche 918 Spyders.
The flywheel-enhanced Porsche 911 GT3 R Hybrid outran the GT field in a Le Mans-class race in China on Sunday, besting the regular 911s, Ferraris and BMWs by more than two laps with one less pit stop. (Photo: Porsche)
