Yamaha unveils hybrid electric motorcycle and limousine scooter

October 28, 2005 Yamaha revealed a hybrid motorcycle concept at the Tokyo Show which is quite unlike any form of two wheeler seen to date. The motorcycle, to be known as the Gen-Ryu, uses the high output lightweight compact YZF-R6 600cc motor and an electric motor to deliver the type of performance normally associated with a much larger capacity engine, and is packaged as a futuristic cruiser with advanced aerodynamics and some form of noise cancelling in the cockpit area to enable voice activation of the navigation system, mobile telephone, intercom communications with the pillion and other similarly equipped riders plus a dazzling array of advanced technologies such as headlights which turn to the inside of the corner and rear cameras playing through LCD screens in the dashboard.

The Gen-Ryu was joined on the Yamaha stand by the previously reported and equally radical stretching and shrinking DEINONYCHUS and the limousine-styled Maxam scooter. With massive overhangs, plush white leather upholstery and long, feet-first styling, the Maxam is the most distinctive two wheeler we’ve ever seen.

Piaggio MP3 HYS

Always considering environmental problems, Piaggio presented a inovative solution destinated to change for ever the way we comute in crowded cities.

Year after year the cities become more and more crowded and with personal transporting becoming a must, somebody had to find a solution. You will probably thing that it was found together with the two wheels but not everybody will agree with you. Many people are scared of getting on two wheels and this is where Piaggio comes in.

After recently releasing Piaggio MP3, the President of Piaggio expressed its intentions to release a hybrid version of the vehicle that will result in providing solutions for congested cities.

The scooter is scheduled for release for the European at the end of the month and it will use Piaggio’ HYS technology.

The Piaggio HYS uses ingenious technical solution and still can be ridden with the usual controls (accelerator, brakes and additional handlebar commands) as well as a specific switch to choose one of four operating modes: standard hybrid, high-charge hybrid, low-charge hybrid and electric only.

In the first three modes the HYS manages power output from the two engines, thermal and electric, using a drive-by-wire system: the electronic management system (SGE) interprets the rider’s request for more torque and selects the assist ratio on the state of the system. During deceleration and braking, the control system recovers and accumulates power that is lost on normal vehicles with battery.

In standard hybrid mode the battery charge is maintained at optimum traction levels (batteries at 75%). In view of “electric only” use, the rider can, however, choose the high-charge hybrid function, geared to maximize the range of the electric motor (batteries at 95%).

On the other hand, if the rider wishes to recharge the batteries by plugging them into a power outlet, he can use the low-charge hybrid mode (batteries at 20%) to obtain maximum performance with minimum consumption.

In electric-only mode, the Piaggio HYS shuts down the combustion engine and turns into a silent, zero-emissions electric vehicle.

Drive-by-wire technology not only allows the control system to optimally manage the combined power output of the two engines but also “forces” the terminal engine to work when it can be most efficient, thereby reducing specific consumption, with obvious advantages in terms of lower consumption and emissions.

Piaggio Launches Two Plug-In Hybrid Vespa Scooters

Piaggio, the Italian manufacturer of the iconic Vespa scooter, has introduced two plug-in hybrid prototypes based on the standard Vespa LX 50 and X8 125 models.

The HyS (Hybrid Scooter) models are parallel hybrids, combining four-stroke combustion engines with electric motors. The electric motor provides power assist, supplying a 25% boost in power for acceleration over the first few meters (a good feature for lunging through urban traffic), while at the same time supporting a 20% decrease in fuel consumption.

The rider uses all the normal controls (accelerator, brakes and additional handlebar commands) as well as a specific switch to choose one of four operating modes:

Standard hybrid
High-charge hybrid
Low-charge hybrid
Electric-only


In the first three modes the HyS manages power output from the engine and the motor using a drive-by-wire type system. The electronic management system interprets the rider’s request for more torque and selects the assist ratio based on the battery’s state of charge.

Regenerative braking recharges the batteries.

In standard-hybrid mode the battery charge is maintained at optimal traction levels (batteries at 75%). The high-charge hybrid function is geared to maximize the range of the electric motor (batteries at 95%).

If, on the other hand, the rider wishes to recharge the batteries using the 220V battery charger by plugging into a power outlet, he or she can use the low-charge hybrid mode (batteries at 20%) to obtain maximum performance with minimum consumption. (Charging time is about three hours.)

In electric-only mode, the Piaggio HyS shuts down the combustion engine and turns into a silent, zero-emission electric vehicle—an important consideration for those European cities that are increasingly placing restrictions on emitting vehicles.

The control system not only manages the combined power output of the engine and motor, but also forces the engine to work when it can be most efficient, thereby reducing specific consumption, with advantages in terms of lower consumption and emissions.

The traction batteries are hidden in the under-seat storage space, which is sufficiently large on the X8 125 HyS to also hold a helmet. The Vespa LX 50 HyS hybrid prototype comes with a top case to hold the helmet.
