Aiming to achieve a motorcycle-like experience on four wheels, the concept is powered by dual electric motors with a gasoline range extender.
Yamaha has revealed the MWC-4, one of several interesting concepts brought to the Tokyo Motor Show.
The concept is described as a Leaning Multi-Wheel (LMW) vehicle with two wheels front and rear and a 1+1 seating arrangement, just a few inches wider than a typical motorcycle.
Power is provided by dual liquid-cooled electric motors, while a small gasoline engine serves as a range extender when the batteries are depleted.
Yamaha says its attitude-control system gives it "a ride that feels like nothing else and a level of comfort not found with a conventional motorcycle."
The company has not indicated any intention to put the MWC-4 into production.
