From onsemi launches EliteSiC M4 silicon carbide platform for EVs and AI

How could onsemi's EliteSiC M4 platform affect Subaru Corporation's EV development?

Possible What happens if… A possibility worth considering, not a forecast.

Subaru may improve EV range and efficiency using onsemi's new SiC platform. The introduction of onsemi's EliteSiC M4, a fourth-generation silicon carbide platform, provides automakers with highly efficient power components. This technology, which offers up to 30% higher power density and 35% lower losses, enables the creation of more compact and efficient traction inverters. Since Subaru Corporation is already engaged in strategic technology evaluation with onsemi for next-generation power architectures, adopting this platform could allow the company to improve vehicle range and performance in its electric vehicles.

The facts so far

As reported. Each one links to where it comes from.

  • EliteSiC M4 is a fourth-generation silicon carbide platform built on a trench architecture.manilatimes.net
  • The platform delivers up to 30% higher power density and 35% lower losses compared with the previous generation.manilatimes.net
  • The EliteSiC M4 750 V automotive traction bare die is available now.manilatimes.net
  • Subaru Corporation and onsemi are engaged in strategic technology evaluation for next-generation power architectures.manilatimes.net

Why it matters

The efficiency of power systems is critical for the viability of electric vehicles, as improved performance directly translates to better vehicle range. For automakers like Subaru, adopting advanced semiconductors like EliteSiC M4 allows them to meet growing consumer demands for longer-range, more powerful, and more compact electric drivetrains.

This technology is part of a broader industry trend where the growth of electrification requires power systems that can deliver significantly more power without proportional increases in size or energy losses. Subaru's existing strategic evaluation with onsemi places it directly in the path of adopting these next-generation power solutions.

What we don't know yet

  • Will Subaru Corporation move from strategic evaluation to actual product integration of the EliteSiC M4?
  • What specific performance metrics or vehicle models will Subaru target for the adoption of this new platform?

What would change this answer

Subaru Corporation announces a partnership or joint development program with onsemiThis would make the adoption of the EliteSiC M4 platform much more certain and accelerate the timeline for its integration into Subaru's vehicles.
Onsemi releases additional voltage options up to 1200 V in 2027This would expand the range of applications for the EliteSiC M4, potentially allowing Subaru to apply the technology to higher-power, heavier-duty EV models.
