design portfolio has always balanced compact efficiency with expressive character, but the new Polygon Concept takes that philosophy in a more experimental direction. This compact EV previews the next-generation 208 and signals the French brand’s vision for a future where architecture, materials, and controls are rethought.
Built on a sub-4-meter footprint, the Polygon modernizes the supermini silhouette with bold geometry and a signature lighting design. The familiar three-claw Peugeot motif is reinterpreted as horizontally arranged micro-LED stripes at both the front and rear, giving the car a sharply modern look. Its body features two large butterfly doors, replacing the conventional four-door layout, which is an expressive choice more suited for concept presentation rather than mass production.
Designer:
The most radical change is on the inside, where the traditional round steering wheel is replaced by what Peugeot calls the “Hypersquare.” Rather than a solid circular rim, this control interface consists of four pods (one at each corner) that house touch-sensitive controls for media, driving modes, and more. Because the system is steer-by-wire, there is no physical linkage between the control and the front wheels. The steering ratio automatically adjusts for different speeds, becoming more direct at low speeds and more stable at high speeds. This setup also filters out any abrupt road vibrations for a smoother riding experience.
Peugeot replaces its conventional instrument cluster with a micro-LED screen placed behind the steering assembly, projecting information directly onto the windshield in a large, immersive format. According to the company, this design creates a cleaner, more open interior while keeping the driver’s attention focused where it matters. Sustainability is central to the Polygon. The cabin uses a “forged textile” made from recycled seat upholstery sourced from end-of-life Peugeot vehicles. Seat shells are 3D-printed from recycled R-PET plastic, while their foam cores come as a single molded piece, reducing complexity. Interior paint also incorporates recycled rubber derived from used tires.
Peugeot designed the Polygon with modular, easily replaceable parts. Elements such as the Hypersquare control, seat foam, dashboard surfaces, and wheel covers can all be swapped out, allowing for personalization and potentially longer ownership. The car uses fewer overall components than a typical production vehicle, which simplifies manufacturing and supports a more circular lifecycle. Another tech highlight: the Polygon’s Goodyear tires feature “SightLine” technology, which monitors pressure, temperature, and road conditions and sends that data to the i-Cockpit system in real time.
While Peugeot has not confirmed detailed powertrain specifications, the Polygon is widely understood to preview a forthcoming fully electric version of the 208. The concept aligns with Peugeot’s plan to bring its Hypersquare steering system to production models around 2027. The Polygon Concept is a bold exploration of future small-car design with a combination of steer-by-wire controls, immersive display technology, and sustainable materials. Peugeot proposes a supermini that is not just efficient, but smarter, more modular, and far more expressive than what exists today.
