Vespa is one of the manufacturers of scooters that are actually developing hybrid scooters! There are two models in the works, based on the popular Vespa LX 50 and the beefier Piaggio X8 125. Each will run on a combination of gas and electric (50cc gas, 1000W electric and 125cc gas, 2500W electric, respectively), with the hybrid drive train expected to boost power by 25% and reduce gas consumption by 20%. "Electric-only" mode will be available for low speeds, and the batteries will charge themselves from the engine (similar to current car models) while you're scooting. They will also plug in to a standard 220V household plug to recharge the batteries in about three hours. The batteries for each live under the seat, so an extra storage space has been added to each for helmets and whatever else you might need while out and about. Now that is something worth waiting for!
