2009 Tokyo Motor Show Yamaha Concept Models

Yamaha debuts new concept models at 41st Tokyo Motor Show

Creating product performance that appeals to human sensibilities. That’s the principle used by Yamaha Motor when developing motorcycles and scooters. We value human perceptions more than hard spec numbers.

At the root of this philosophy are Yamaha’s Smart Power ideals. Smart Power is about looking to electricity and other alternative power sources – to produce vehicles which combine environmentally-friendly performance with completely new kinds of riding pleasure.

It is a concept that might, for example, take the design freedom allowed by the structural simplicity of an EV (Electric Vehicle), or the start-up acceleration potential of an HEV (Hybrid Electric Vehicle) – then turn these qualities into new forms of enjoyment or surprise.

Yamaha Smart Power solutions can be seen at the 41st Tokyo Motor Show in the following concept models:

Yamaha EC-03

Yamaha EC-03The EC-03 is a 100% electric powered commuter vehicle, developed with a concept of “Light, Smart, Clean and Silent.” Its slim electric power unit and lithium-ion battery are mounted on a lightweight aluminum frame. Yamaha-exclusive motor control technology provides smooth start-ups and acceleration. The charger is built into the vehicle, for easy recharging from a home electric outlet.

[Power unit]= Permanent magnet type synchronous motor
[Rated output]= Equivalent to 50cc license category at less than 0.6 kW
[Battery type]= Lithium-ion battery
[Charger type] = Onboard plug-in type

Yamaha EC-f/EC-fs

Yamaha EC-fThe EC-f and EC-fs are electric commuter vehicles designed to provide easy, motorcycle-style riding for people of all age ranges and experience levels. They combine futuristic styling with the ease of use, quietness and smoothness that only an electric vehicle can provide. The EC-f features colouring which accentuates its clean, commuter-oriented design, while the EC-fs offers a stylish alternative colour scheme.



Yamaha HV-X

Yamaha HV-XThe HV-X fits a compact hybrid system into a motorcycle design. As a hybrid it offers environmentally-conscious performance, with low emissions and improved fuel efficiency - while still providing the high-quality acceleration and pleasurable cruising performance of a conventional motorcycle.

Yamaha Motor continues to research and develop smarter, more compact, hybrid motorcycle designs. This forms part of our corporate mission: to achieve both environmentally sound performance and Kando.


Yamaha PAS Brace-L Special

Yamaha PAS Brace-L SpecialPAS bicycles were developed and marketed by Yamaha Motor as the world’s first electro-hybrid bicycles, running on a combination of human pedaling power and an electric motor. They were originally released in limited areas of Japan in 1993 and nationwide in 1994.

The PAS Brace-L Special is an electro-hybrid bicycle with a sporty style and riding performance, with male riders as its primary target group. Incorporated is the Yamaha S.P.E.C.8 (Shift Position Electric Control x in-hub 8-speed gear mechanism); this provides an appropriate assist level for each gear, ensuring a sporty ride in all conditions and speed ranges, from start-ups and acceleration to cruising. The concept model is stylishly outfitted with a quality finish and special parts.

[Length x Width]= 1,760mm x 550mm
[Seat height]= 820 - 1,000mm
[Wheelbase]= 1,115mm
[Tire size] = 26-inch front & rear
[Vehicle weight] = 23.1kg
[Motor rated output] = 240W
[Battery type] = Lithium-ion battery
[Battery voltage/capacity]= 25.2V/8.1Ah
[Charging time] = Approx. 4hrs.

PAS er (Special exhibition vehicle)

The PAS er is a prototype model, developed on the concept of a more advanced hybrid relationship between the rider and the motor. It adopts a two-wheel-drive mechanism that applies the electric motor “assist” to both the front and rear wheels, and an automatic electronic transmission. These features contribute to a smooth, enjoyable ride, even over changing road surface conditions. The motor of the front wheel features a regenerative function that charges the battery during deceleration or downhill riding.

There is also a sensor that monitors the rider’s heart rate and adjusts the assist level, helping to maintain an appropriate level of rider exertion. To accompany this function, there is a large LCD meter panel with a speedometer and multi-information display showing calorie consumption etc. The model also features shaft drive and styling defined by a simple, modern design.

[Length x Width]= 1,600mm x 525mm
[Seat height]= 820 - 1,000mm
[Wheelbase]= 1,080mm
[Tire size]= 20-inch front & rear
[Motor rated output]= Front wheel hub motor 100W center motor 150W
[Battery type]= Lithium-ion battery
