Yamaha’s New Hybrid Revolution
Yamaha has recently unveiled a prototype hybrid motorcycle that blends traditional petrol power with not one, but two electric motors. This innovative petrol-electric hybrid powertrain marks a significant advancement in motorcycle technology, demonstrating Yamaha’s commitment to eco-friendly and efficient riding solutions.
Understanding the SPHEV System
The heart of Yamaha’s prototype is the Series-Parallel Hybrid Electric Vehicle (SPHEV) system, which has been ingeniously designed to offer multiple operating modes. From low-speed full electric running to a combined power output for maximum straight-line speed, this motorcycle showcases versatility in performance. Currently tailored for a mid-class scooter, the prototype is based on a modified Yamaha XMAX.
How It Works: Power Sources Combined
While Yamaha has not disclosed exact specifications for the engine size or battery capacity, we know that the system includes an internal combustion engine alongside two electric motors. The ‘drive’ motor is integrated directly with the rear wheel, providing torque and enabling regenerative braking to recharge the battery during deceleration. The second motor, the ‘generator’ motor, is connected to the petrol engine’s crankshaft, working in tandem with the combustion engine to generate electricity.
This prototype reflects the first implementation of such a hybrid system in the motorcycle industry, hinting at an exciting future for Yamaha’s three-cylinder 890cc CP3 platform. With this blend of technology, Yamaha is paving the way for a new era of motorcycling that harmonously balances performance with environmental consideration.
