Subaru Unveils In-House EV Platform to Reduce Toyota Reliance

Subaru Corporation unveiled a new in-house electric vehicle platform and prototype at its proving ground north of Tokyo on October 18, 2026. The all-wheel-drive prototype produces 510 horsepower and accelerates from 0 to 62 mph in under four seconds. This proprietary architecture is approximately 100 kilograms lighter than current Subaru EVs and includes a redesigned front structure to improve crash safety.

The platform integrates e-axle motors developed with Aisin Corp and a cylindrical-cell battery from Panasonic Energy that is 25% lighter than previous versions. To modernize its software capabilities, Subaru collaborated with AMD to create a custom system-on-chip for an integrated electronic control unit, enabling AI functions for the EyeSight safety suite and over-the-air updates.

While Subaru maintains its partnership with Toyota, the company developed this technology to reduce dependence on Toyota's platforms and better preserve its specific driving character. The company expects the proprietary technology to enter production around 2029.
