Yamaha announces electric engine supply agreement with Subaru

Yamaha Motor will be the official electric engine supplier for the Subaru STI E-RA electric vehicle (EV) concept car that the latter is developing for future motorsport applications.

The STI E-RA is being developed by Subaru with the aim to gain experience and practice in new technologies in the world of motorsport, which is fast approaching a carbon-neutral era.

Its concept model, the STI E-RA CONCEPT, has been on display at the Subaru/STI booth at the Tokyo Auto Salon 2022, at the Makuhari Messe exhibition complex in Chiba, Japan.

According to Yamaha, the new electric engines which the STI E-RA will use were “developed to be ‘emotional electric engines’ that leverage the technologies and engineering sense we have garnered via our engine development to date. Further, thanks to our casting and machining technologies accrued through developing engines, the adoption of high-efficiency segment conductors, and more, these units achieve high output while being compact in size.”

In July 2021, Yamaha Motor reviewed its Environmental Plan 2050, which was originally formulated in 2018, for the entire group and set a new goal of aiming for carbon neutrality throughout all of its business activities — including across the lifecycles of its products — by 2050.

Among these changes, Yamaha Motor has set a goal of reducing Scope 3 CO2 emissions (emissions produced from the Company’s value chain, e.g., use of sold products) by 90% by 2050 compared to 2010, and the commissioned development of prototype electric motors is one of the Company’s initiatives toward achieving this goal.
