Italian manufacturer Piaggio, the maker of Vespa, is set to become the first company to release a hybrid drive scooter following an announcement that it is developing hybrid versions of its Vespa LX, Piaggio X8 and Vespa MP3 (the carving three-wheeler) models. The new hybrid system, which has a working title of HyS (Hybrid Scooter), can operate in full electric mode with a range of around 20 kilometres as well as hybrid mode - whenever the rider needs to accelerate more aggressively, the electric motor kicks in, providing about 85 per cent extra performance. Piaggio’s HyS system is a parallel hybrid in which a combustion engine and an electric motor incorporated into the gearbox casing are mechanically and electronically linked and simultaneously supply power to the rear wheel. The system uses drive-by-wire and the in-built electronic management combines the two engines to offer not only better acceleration but also a significant reduction in fuel consumption (up to 170 mpg or 1.67 liters/100 km) and in CO2 emissions, only 40 g/km (using 65% the hybrid modes and 35% the electric one). Perhaps the most exciting prospect is the hybrid MP3 which enjoyed such success as a 250cc it has since been developed as a 400cc version and was recently shown as a stylish 500cc Gilera – a sportier hybrid version of the 500 would enjoy exceptional performance.
