The new electric vehicle architecture features a 380kW all-wheel-drive setup, a next-generation battery and advanced electronic systems as Subaru prepares to reduce its reliance on Toyota.
Subaru has unveiled its first independently developed electric vehicle (EV) platform, marking a major step towards building future electric cars without direct assistance from Toyota. The Japanese automaker plans to introduce production models based on the new architecture from 2029.
The platform was demonstrated at a Japanese test track beneath a modified Subaru Outback wagon body. The prototype features an extended wheelbase to accommodate its electric architecture and showcases technologies that will underpin the company’s next generation of EVs.
Subaru Develops Its Own Electric Technology
Subaru has relied on its partnership with Toyota for its first three electric SUVs: the Solterra, Trailseeker and Uncharted. Toyota holds a 21.46% stake in Subaru and remains its largest shareholder.
However, the new platform signals Subaru’s intention to strengthen its independent engineering capabilities. The company aims to preserve its distinctive driving characteristics while developing electric technologies tailored to its own vehicles.
According to Subaru engineering executive Takatomo Watamori, in-house development will help the automaker respond more quickly to changing market demands while maintaining its focus on driving enjoyment and customer confidence.
380kW Powertrain Targets Performance
The test vehicle uses two electric drive units developed with Aisin. Its front motor produces 150kW, while the rear motor generates 230kW, delivering a combined output of 380kW.
Subaru claims the all-wheel-drive prototype can accelerate from zero to 100km/h in under four seconds. This would make it quicker than the Trailseeker, which has a claimed acceleration time of 4.4 seconds.
The prototype also features a battery developed with Panasonic Energy. The pack contains 4,000 cylindrical cells and is reportedly 25% lighter than Subaru’s previous battery design. The company is targeting energy density 20% above the industry average, although battery capacity, chemistry and driving range remain undisclosed.
New Software Systems and Electrification Strategy
Subaru is developing an integrated electronic control unit with US-based Advanced Micro Devices. The system will manage powertrain, chassis and infotainment functions while supporting artificial intelligence, advanced driver-assistance features and over-the-air software updates.
Despite expanding its EV technology, Subaru has adjusted its electrification timeline. Its target of achieving 50% global sales from electric vehicles remains in place, but the company now expects to reach it later than originally planned.
Subaru is also redirecting part of its planned ¥1.5 trillion electrification investment towards petrol and hybrid models as demand patterns change. The strategy reflects its decision to balance electric vehicle development with continued investment in conventional engines and stronger hybrid systems.
The new platform represents an important step in Subaru’s long-term EV ambitions, with production vehicles expected to begin arriving from 2029.
