Yamaha Tesseract leaning over.
In the run-up for the Tokyo Motor Show, the Japanese manufacturers have been giving brief previews of some of the exhibition models that will be on display. Last month Honda unveiled three prototypes
, including the EVO6 and a pair of retro-styled models based off the marque's popular CB designs. Yamaha has also released a host of prototype exhibition models, 19 in fact, which also includes a retro-themed design - the XS-V1 Sakura.
Taking styling cues from the Tuning Fork brand's first four-stroke, the 1970 XS-1, the new Sakura will be on display at the Yamaha booth in the Tokyo Motor Show from October 27 - November 11. The original XS-1 housed a 650cc parallel Twin, but the new Sakura is powered by a 1000cc air-cooled V-Twin, which the manufacturer promises to deliver a "strong pulse feeling and easy-going running performance in a finely crafted body that is lightweight and slim and defined by a low seat height."
Prior to the Sakura introduction, Yamaha
also released teaser shots and information regarding some interesting alternative fuel vehicles. First among these is the wild looking Tesseract, which looks kind of like the offspring of an unholy union between a quad and R6. The four-wheeler is a hybrid design utilizing a gasoline V-Twin and an electric motor. In spite of four wheels, Yamaha touts the Tesseract's handling is similar to that of a two wheeler due to the "dual-scythe suspension." The design enables banked leaning similar to a motorcycle, while a dual arm-lock system ensures the quad remains upright while at a rest.
The Yamaha LUXAIR prototype is a hybrid gas/electric design that features luxo-scooter styling.
A second hybrid prototype is the luxo-scooterish LUXAIR, which also features a gas/electric configuration. The electric motor assists in acceleration, recharging while at cruising speeds and upon deceleration when it utilizes the engine braking. Another feature mentioned in Yamaha PR is the YIPU (Yamaha Intelligent Power Unit), a design built into the rear hub that delivers the electric acceleration power and "when wheeling the vehicle by hand" - whatever that means. The YIPU also supplies a reverse.
The FC-Dii is a fuel cell two-wheeler that sources a methanol-water solution for power. Based on a design which debuted in 2005, Yamaha brags the latest prototype offers up significant performance enhancements.
The Yamaha FC-AQEL is a Tokyo Motor Show prototype which utilizes a "Yamaha Hydrogen Fuel Cell System."
Another vehicle utilizing fuel cell technology is the FC-AQEL, which sources compressed hydrogen gas for energy. A secondary rechargeable battery is also utilized, making it a hybrid design as well. Like the LUXAIR it incorporates the YIPU design.
Two all-electric designs are also on display from Yamaha. The first is BOBBY, an all-black electric scooter that resembles a fold up bicycle, which makes sense as the prototype features fold-in handlebars, footrests and rear wheel. The small commuter design showcases some interesting electronic features, like the owner being able to turn the power switch on and off with their cell phone, as well as the ability to "access a variety of Internet services." Almost sounds like a laptop you can ride to work!
The second all-electric two-wheeler is the C3+ scooter, which Yamaha describes as a "minimum electric commuter." It appears to be an electric version of the C3 scooter Yamaha unveiled in the U.S. last year.

Highlights of the "40th Tokyo Motor Show 2007" Yamaha Booth and the display model, "XS-V1 Sakura" (special exhibition model / prototype)
Taking styling cues from Yamaha's first four-stroke motorcycle, the XS-1, the tuning fork brand will showcase the prototype XS-V1 Sakura at the upcoming Tokyo Motor Show October 27 - November 11.
Yamaha Motor Co., Ltd. is proud to announce that it will be displaying 19 exhibition models in a booth organized around the concept of "The Art of Engineering" at the upcoming 40th Tokyo Motor Show 2007 to be held over the 16 days from Oct. 27 (Sat.) to Nov. 11 (Sun.) (Organizer: Japan Automobile Manufacturers Association; Venue: Makuhari Messe, Chiba Pref.; Special invitation day: Oct. 26). Among the world premiere models to be unveiled for the first time in the world at this Tokyo Motor Show, we introduce the special exhibition model, "XS-V1 Sakura," a model that boasts the latest technologies in its 1,000cc, air-cooled V-twin engine and chassis, while featuring a "Japanese style" look integrated with an image of the XS-1, Yamaha's first 4-stroke model (released in 1970 / 650cc).
As with the 37th and 39th shows, the Yamaha booth concept for the 40th Tokyo Motor Show is "The Art of Engineering." In a more radical design than ever before, the booth seeks to express the true essence of Yamaha by presenting the entire booth as a "Yamaha Museum" and displaying models as works of art that are the realizations of Yamaha's corporate principle: to be a company that creates Kando*. In this way we hope to express the possibilities and the beauties of the motorcycle as a vehicle and the enjoyment it can bring. The "art" we wish to express is steeped in the Yamaha philosophy that the surprises, excitement and new discoveries a motorcycle can bring are not to be found merely in performance specs. And, in order to allow visitors to fully appreciate these works of "art," the booth is designed so that most of the models on display can be looked at from all angles.
The booth is also designed to present the conceptual art of Yamaha motorcycle design and engineering by presenting our definitive design ideals of (1) "GENESIS," the engineering ideal that sees the engine, the chassis and the other main components of a motorcycle not as individual mechanisms but as integrated parts of a single whole, (2) the "G.E.N.I.C.H." ideal that pursues the active adoption of the latest electronic control technologies in ways that achieve ever higher levels of "rider-machine communication" based on human perceptions, and (3) "Smart Power," the concept of achieving both customer excitement and eco-friendliness with new power sources capable of creating exciting new riding experiences. We hope to also express the ideal of "Functional Beauty" in Yamaha motorcycles where performance is expressed directly in the sculpted forms of the motorcycle's components in a high-level fusion of function and beauty.
Also, we display the "XS-V1 Sakura" (special exhibition model / prototype) as a symbol of our long-nurtured corporate philosophy. This is a V-twin sport model with a look of "Japanese style" in the image of Yamaha's first 4-stroke model, the XS-1 (650cc), released in 1970. Its design is full of XS-1 DNA, in its simplicity and functional beauty and finds new refinement in a retro-modern aesthetic. It is a model that proposes a very Yamaha and very Japanese vision of premium motorcycling life, bringing together the unique characteristics of a 1,000cc air-cooled, V-twin model with its strong pulse feeling and easy-going running performance in a finely crafted body that is lightweight and slim and defined by a low seat height.
*Kando is a Japanese word for the simultaneous feeling of deep satisfaction and intense excitement that people experience when they encounter something of exceptional value.
Tesseract (Special exhibition model / prototype)
The Tesseract is a crazy-looking quad that sports a "dual-scythe suspension," which allows banked handling similar to a motorcycle.
This is a hybrid 4-wheeled vehicle powered by a combination of a liquid-cooled V-twin gasoline engine and an electric motor. It is also designed with a unique dual-scythe suspension that enables cornering with a lean (banking) like a motorcycle despite the 4-wheel format. There is also a dual arm-lock system that keeps the machine upright when at rest without a stand. It offers excellent performance and maneuverability with a machine width roughly equivalent to that of a 2-wheeler.
LUXAIR (Special exhibition model / prototype)
This is a hybrid type motorcycle with a gasoline engine and an electric motor that function in parallel, with the electric motor kicking in during acceleration to assist the engine and switching over when cruising to perform a electricity generating function that re-charges the battery. The engine-brake force created during deceleration is also used to generate electricity to charge the battery. Yamaha's super-thin YIPU (Yamaha Intelligent Power Unit) is built into the rear hub to provide the electric power assist during acceleration and when wheeling the vehicle by hand, and it also provides a reverse function. In a collaboration with Yamaha Corp. (music) this model also mounts a special audio system.
FC-Dii (Special exhibition model / prototype)
Ultilizing fuel cells as a power source the Yamaha FC-Dii concept gets its wheels turning from a methanol-water solution.
This model is a further evolution of the "FC-me" fuel cell motorcycle using a methanol-water solution as fuel, unveiled in Sept. 2005 with significant performance improvements. This new version is enhanced with new features including: (1) a Yamaha-exclusive compact cell stack that features the highest level of power density in the 1kW class, (2) a detachable lithium-ion battery for easy recharging, (3) modular design components, readily available parts and improved serviceability aimed at achieving practical use and (4) a fuel cell system which achieves a top-level performance of 30% system efficiency for a DMFC (Direct Methanol Fuel Cell) system. The development of this model has been assisted with some funding from the New Energy and Industrial Technology Development Organization (NEDO).
BOBBY (Special exhibition model / prototype)
The BOBBY is an all-electric commuter that features fold-in handlebars, footrests and rear wheel to aid in easy storage.
This is an electric commuter vehicle with collapsible seat, fold-in rear wheel, handlebars and footrests for compact, convenient storage. For owners of a cell phone with the FeliCa* function, the main power switch can be turned on and off simply holding up your cell phone to the switch. The bike is also equipped to access a variety of Internet services. * FeliCa (registered trademark) is a non-contact IC card technology developed by SONY Corp.
C3+ (Special exhibition model / prototype)
This is a convenient "minimum electric commuter" bike with a light weight, compact body with a helmet storage space.
FC-AQEL (Special exhibition model / prototype)
The prototype C3+ appears to be an all-electric version of the 50cc scooter released in the U.S. as a 2007 model.
This is a fuel cell motorcycle mounting the "Yamaha Hydrogen Fuel Cell System" fueled by compressed hydrogen gas from a tank with a capacity of 35MPa. By adopting a hybrid system mounting a secondary rechargeable battery and metal separators in the fuel cells, it has been possible to achieve a compact lightweight design. The adoption of Yamaha's super-thin YIPU (Yamaha Integrated Power Unit) also improves environmental performance and increases ease of use as a commuter bike.
