Subaru has taken the wraps off a bold vision of its performance future with the Performance E STI concept at the Japan Mobility Show 2025. The four door sedan blends classic rally inspired styling cues with a modern electric architecture. In parallel, Subaru is also exhibiting the Performance B STI concept, a prototype that keeps the brand’s signature horizontally opposed boxer engine alive for enthusiasts who still prefer internal combustion. Together, the pair signals Subaru’s intent to evolve its performance lineup in two complementary directions while maintaining the core attributes of grip, balance, and everyday usability.
What Is the Performance E STI Concept
The Performance E STI concept is an all electric performance sedan designed to represent the trajectory of Subaru’s next generation models. Subaru describes it as a driver friendly package with a roomy interior. While detailed specifications have not been released, the brand confirms the presence of an electric motor on each axle that enables permanent all wheel drive. This setup is consistent with Subaru’s long standing emphasis on traction and stability and lays the groundwork for sophisticated torque distribution between the front and rear.

Design and Heritage
Visually, the Performance E STI pays homage to Subaru’s rally legacy. The concept wears a deep blue exterior that nods to the brand’s iconic competition liveries, set off by gold wheels and pink STI detailing. The stance is low and planted with pronounced wheel arches and aerodynamic sculpting that suggests serious performance intent. Subtle references to past Group A winners are blended with sharp surfacing and modern lighting signatures, creating a look that is both familiar to longtime fans and forward looking for the EV era.
Electric Powertrain and AWD Strategy
A dual motor configuration sits at the heart of the concept. Placing one motor on each axle allows a robust interpretation of Subaru’s symmetrical all wheel drive philosophy in an electric format. In practice, this approach could deliver millisecond level front to rear torque modulation, crisp launches, and enhanced stability across mixed traction surfaces. Although numbers are not yet public, the architecture is well suited to deliver strong acceleration while preserving the composure that Subaru performance cars are known for.
Chassis and Dynamics Outlook
Subaru’s STI division typically tunes spring rates, dampers, bushings, and geometry for agility and control. Even without final figures, it is reasonable to expect the Performance E STI to pair a rigid body structure with a low center of gravity thanks to a floor mounted battery. The resulting weight distribution should support quick direction changes and a neutral balance. Expect large brakes, sticky performance tires, and active control systems designed to keep handling predictable on road while leaving headroom for track day exploration.
Interior Philosophy
Subaru describes the layout as driver friendly and comfortable, with a spacious cabin that is practical for daily use. The concept likely emphasizes excellent outward visibility, intuitive controls, and supportive seating with STI themed trim. Expect digital displays that present telemetry and drive mode settings clearly, along with refined materials that fit the premium performance brief.
Where It Fits in the Subaru Lineup
The Performance E STI concept is a statement of intent for Subaru’s electric performance roadmap. It slots alongside the brand’s established WRX and STI heritage by delivering AWD traction and driver engagement in a modern EV form. As the industry transitions, such a concept bridges loyal STI customers to the electric future without abandoning the sensations that built Subaru’s reputation.
Performance B STI Concept
Sharing stage space is the Performance B STI concept, understood to be based on the current Impreza. This prototype keeps a horizontally opposed internal combustion engine and AWD. Subaru has not disclosed output or technical changes, but the boxer layout is central to the marque’s identity. By displaying both concepts, Subaru signals a dual track strategy that nurtures combustion enthusiasts while developing a parallel EV performance line.
Performance E vs Performance B
- Power Source
Performance E STI uses a dual motor electric system. Performance B STI continues with a boxer engine. - AWD Method
Performance E STI deploys electric torque on both axles for rapid distribution. Performance B STI uses a mechanical AWD layout. - Character
Performance E STI leans into instant torque and quiet thrust. Performance B STI preserves the mechanical sound and feel of a traditional STI tuned setup. - Strategic Role
Performance E STI previews Subaru’s long term electrified performance direction. Performance B STI reassures existing fans that the boxer experience remains part of the conversation.
Availability and Next Steps
Subaru has not announced production timing, final specifications, or pricing for either concept. Automakers often use mobility shows to gauge public reaction, refine engineering targets, and validate design themes before moving to road ready prototypes. Interested buyers should monitor Subaru’s official channels for updates on technical specifications, performance numbers, battery range, charging capability, and market rollout plans.
Why This Concept Matters
Performance brands face the challenge of translating their signature dynamics into electric platforms while managing weight, range, and thermal constraints. The Performance E STI concept addresses that challenge by putting AWD traction, driver centric ergonomics, and heritage styling at the forefront. If realized with production ready hardware, it could set the tone for a new era of Subaru performance that remains authentic to the STI ethos.
