Yamaha Files Patent For Electric Turbo Engine To Boost CP3 Platform Performance

Yamaha appears to be preparing for a new era in high-performance motorcycles, with a recent patent application revealing an innovative electric turbocharger design for its CP3 three-cylinder engine. The system, aimed at drastically increasing power and throttle responsiveness, could potentially push performance beyond the current 119 hp found in models like the YZF-R9 and MT-09.

The patent outlines a unique setup featuring an electronically controlled turbocharger. Unlike traditional turbos or hybrid systems, Yamaha’s design avoids the use of a heavy battery pack. Instead, the turbo unit is powered by a generator linked to the engine’s crankshaft, likely using a high-voltage electric system, similar to what's seen in some modern automotive e-turbo applications. This arrangement allows for faster turbo blade rotation, reducing lag and enhancing acceleration response without compromising the engine’s compact form factor.

This move puts Yamaha in close technological contention with Honda, which is reportedly developing an electric compressor for its V3 engines. However, while Honda’s system is thought to be nearing production, Yamaha’s latest innovation remains at the conceptual stage. Yamaha has explored turbocharging technologies before but has not yet brought such a system to market. The new electric turbo patent could signal a serious push towards realising forced-induction motorcycles that deliver both efficiency and thrilling performance.

If brought to production, the electric turbo-equipped CP3 engine could represent a major advancement in the performance motorcycle segment, blending the benefits of turbocharging with electric control precision. It remains to be seen when or if the concept will become reality, but the patent confirms Yamaha’s ongoing interest in redefining motorcycle powertrains in an increasingly electrified landscape.
