Subaru Reveals 510-HP Prototype for Its Own EV Platform
The prototype features a 25% lighter battery and aims for production around 2029, reducing reliance on Toyota architecture.
Subaru is developing a proprietary electric vehicle platform to reduce its dependence on Toyota, showcased by a 510-horsepower all-wheel-drive prototype presented at its proving ground north of Tokyo.
What Happened
According to Automotive News, Subaru revealed the prototype on October 18. The vehicle, described as a development mule resembling a modified Outback, accelerates from 0 to 62 mph in under four seconds. The new architecture targets a 100-kilogram (220-pound) weight reduction compared to Subaru’s current EVs and features a battery pack with 4,000 cylindrical cells that is 25% lighter than previous iterations.
The prototype utilizes drive units developed by Aisin and batteries supplied by Panasonic Energy. Engineers claim a 30% efficiency improvement in the motors, though the benchmark for this comparison was not specified. Subaru has not disclosed the battery capacity, driving range, or charging performance of the prototype.
Why It Matters
This move signals Subaru’s intent to shape the complete vehicle experience rather than adapting shared Toyota platforms. Engineering executive Takatomo Watamori stated that controlling underlying technology helps preserve the brand’s safety and driving character. The new platform includes an integrated electronic control unit co-developed with AMD, enabling over-the-air updates and AI functions for a future version of the EyeSight driver assistance suite.
For buyers, this could mean Subaru-specific driving dynamics and safety features distinct from its Toyota siblings like the Solterra and Trailseeker. The company aims to manufacture this control unit in-house to reduce costs across its lineup. While Subaru sold approximately 924,000 vehicles globally in 2025, it targets 1.2 million annual deliveries in the early 2030s, supported by 10 new vehicles.
The Bottom Line
Subaru has not confirmed a production model or a firm launch date, though some technology could enter production around 2029. The partnership with Toyota remains intact, but Subaru is accelerating its in-house development to keep pace with Chinese competitors. The prototype’s hardware may also inform future performance models, potentially linking to the Subaru Performance-E STI concept, though no production decisions have been finalized.
