The new EC-03 is a “zero-emissions” vehicle with a smooth and quiet ride that also allows the rider to enjoy lightness and slim design not found in conventional 50cc scooters. This model features a new high energy density 50V lithium-ion battery manufactured by SANYO Electric Co., Ltd. and Yamaha Motor’s exclusive super-slim Yamaha Integrated Power Unit (YIPU), which combine to provide smooth running performance at all times. Furthermore, it achieves a running distance per charge of 43km (@ 30km/h on a flat road) to provide the functionality and running performance desired for short-range transportation needs in the urban environment.
This new model also features plug-in recharging from a 100V household electrical outlet (3-hole grounded type), excellent ease of maneuvering thanks to its lightweight aluminum alloy frame and other features to ensure the high level of functionality and convenience as a “smart, minimal commuter” vehicle. Prior to its market release, advance orders for EC-03 will be accepted at designated dealerships beginning from July 15 in the Tokyo metropolitan area and nationwide from September 15, 2010.

Leaders in a variety of fields are working to solve environmental problems and improve economic efficiency for the society of tomorrow by clustering or dispersing urban activity into a new structure, in which vehicles are used more selectively than they are now – e.g. automobiles for long-distance traveling while motorcycles for short-distance traveling. Small motorcycles offer excellent mobility for easy short-distance transportation, ideal for the transportation needs of the new society. They will provide still greater convenience and ease of use when they are powered by electricity.

In 2002, Yamaha Motor became the first manufacturer to market a production-model electric commuter, the Passol, as a minimal commuter designed to play a role in next-generation urban transportation. Then in 2005, Yamaha Motor released the Passol-L and the EC-02 with further improvements in the motor and higher energy density batteries that combined to increase running distance per charge. Due to exclusive technologies, such as the electronic control technology garnered from Yamaha Motor’s PAS electrically power assisted bicycle development, these models offer a level of quietness and smoothness to the ride that only an electric vehicle can provide. As a result, they have been put to use in a growing range of areas besides short-range urban commuting, including use as rental vehicles in tourist areas and fleet vehicles in resorts.
The new EC-03 has been developed as a “personal commuter” vehicle that is expected to find even more diverse uses in the future. For Yamaha Motor, this model is a manifestation of our efforts to develop new forms of “Smart Power” as defined in our current medium term management plan.
