Subaru is developing its own dedicated electric vehicle platform, aiming to reduce its reliance on Toyota and bring more of its signature all-wheel-drive performance and safety engineering to future EVs.
The new architecture promises more powerful electric motors, a lighter battery, improved crash protection, and over-the-air software updates, with some of the technology expected to reach production vehicles from 2029.
The Japanese automaker recently demonstrated a prototype at its proving ground north of Tokyo, revealing key details of the next generation of its electric vehicle technology. Although the test vehicle uses a modified Subaru Outback body, it serves as an engineering mule rather than a preview of a confirmed production model.
According to Automotive News, the all-wheel-drive prototype produces approximately 510 horsepower from two electric motors and can accelerate from 0 to 62 mph (100 km/h) in under four seconds.
Subaru’s current electric lineup includes the Solterra, Uncharted, and Trailseeker, with the three-row Getaway also planned. However, these models were developed through its partnership with Toyota, which has played a major role in their underlying EV technology.
The collaboration has helped Subaru expand its electric vehicle portfolio, but the company wants greater control over the engineering decisions that define its vehicles. Developing a dedicated EV platform would allow Subaru to shape its electric powertrains, battery systems, vehicle dynamics, and safety technologies around its own priorities.
Subaru engineering executive Takatomo Watamori told Automotive News that developing proprietary technology is important for preserving the brand’s distinctive driving character and safety focus, particularly its all-wheel-drive systems.
While Subaru engineers have contributed to the all-wheel-drive development and motor tuning of existing models, a dedicated architecture would give them greater control over the entire vehicle instead of adapting technology shared with Toyota.
510-HP Dual-Motor Powertrain Targets Better Efficiency
The new platform features a dual-motor all-wheel-drive system with a combined output of around 510 horsepower. The front motor produces approximately 201 hp, while the rear unit delivers 308 hp.
Both motors were developed with Aisin, a supplier within the Toyota Group. Despite the continued involvement of Toyota-affiliated companies, Subaru says the new units are more compact and lighter than those used in its current electric vehicles.
Engineers also claim the motors are approximately 30% more efficient than the industry average, potentially helping future Subaru EVs balance performance with energy consumption.
The platform incorporates a new integrated control unit and supports over-the-air software updates, allowing certain vehicle systems to receive improvements remotely. Together, these technologies could provide a more flexible foundation for future electric models.
Lighter Battery Developed With Panasonic Energy
Battery technology is another major part of Subaru’s development program. The company began working with Panasonic Energy on the new battery in September 2024.
The pack uses approximately 4,000 cylindrical cells and is reportedly 25% lighter than Subaru’s previous battery. The automaker is also targeting energy density around 20% above the industry average.
Reducing battery weight can improve vehicle efficiency, handling, and overall performance, while higher energy density could allow future models to store more energy without a proportional increase in battery size and mass.
Subaru is targeting an overall platform weight reduction of approximately 100 kilograms (220 pounds) compared with its current EV architecture. The combination of lighter motors, a redesigned battery, and a more efficient vehicle structure could help the company improve the performance and efficiency of its next-generation electric vehicles.
New Platform Focuses on Crash Protection
Subaru is also placing significant emphasis on occupant and battery protection. The new architecture features a redesigned front structure intended to absorb and distribute crash energy more effectively.
Structural supports curve over the front wheels to help manage impact forces, while the front electric motor is designed to rotate during a collision. This movement is intended to help dissipate energy and reduce the risk of crash forces reaching the passenger compartment or battery pack.
These changes reflect Subaru’s goal of carrying its established safety priorities into its next generation of electric vehicles rather than simply adapting existing vehicle platforms.
The company is also developing a next-generation EyeSight driver assistance system that will use artificial intelligence and a new electronic control unit. The technology is part of a broader effort to advance driver assistance and vehicle safety across its future lineup.
Subaru’s EV Strategy Moves Beyond Toyota
Subaru’s electric vehicle ambitions began well before its current partnership with Toyota. In the 2000s, the company developed the small R1e electric car with Tokyo Electric Power Company, followed by the fully electric Plug-in Stella in 2009. The latter entered limited production, with approximately 170 examples reportedly built.
The launch of the Solterra in 2023 marked the beginning of Subaru’s modern EV expansion. Closely related to the Toyota bZ4X, it was followed by plans for additional electric SUVs, including the Uncharted, Trailseeker, and three-row Getaway.
The partnership has given Subaru a faster route into the EV market, allowing it to expand its lineup without shouldering the full cost of developing every component independently. However, its next platform represents an effort to establish a more distinct technical identity as competition in the electric vehicle market intensifies.
Subaru is not abandoning collaboration with outside suppliers. Aisin remains involved in the motor development, while Panasonic Energy is contributing to the battery program. Instead, the goal is to gain greater control over the overall architecture and how its individual systems work together.
Beyond electric vehicles, Subaru is also working on more efficient combustion engines for future gasoline and hybrid models, suggesting that its development strategy will continue to cover multiple powertrain technologies.
First Subaru EVs Using the New Platform Could Arrive From 2029
Subaru has not confirmed a production vehicle, final specifications, or a firm launch date for its dedicated EV architecture. The company has indicated that some of the new technologies could reach customers starting in 2029.
That timeline leaves room for further development, and the 510-hp prototype should not be treated as confirmation that a future production model will deliver the same power or use an Outback-based design.
The more important development is Subaru’s effort to take greater ownership of its electric vehicle technology. If the new architecture delivers on its targets for weight reduction, motor efficiency, battery performance, and crash protection, it could give the automaker a stronger foundation for differentiating future EVs from their Toyota counterparts.
For Subaru, the challenge is no longer simply expanding its electric SUV lineup. It is building electric vehicles that retain the engineering characteristics and brand identity that have traditionally set its vehicles apart.
