Motocycle company Vespa is currently developing hybrid scooters based on its LX 50 and the Piaggio X8 125. Both prototypes' drivetrains will deliver a 25% power increase while delivering a 20% better fuel efficiency. Unlike today's production hybrids like the Toyota Prius or Ford Escape/Mercury Mariner, the scooters' batteries can be recharged via a regular household plug.
