Peugeot has never shied away from turning heads with its concept cars, and the new Polygon is no exception. At first glance, its oblong steering “wheel” seems like a designer’s indulgence, more suited to a runway than a road. But in reality, it’s a serious glimpse into the future: steer-by-wire technology.

The Polygon’s steering wheel has no mechanical link to the front wheels. Instead, it’s fully electronic, driven by two redundant 12V motors at the rack and a smaller motor in the dash providing tactile feedback to the driver. The system filters unwanted vibrations, torque steer, and even compensates for crosswinds—while still relaying the grip limits of the front tires. In short, it’s not sci-fi; it’s imminent.
Peugeot calls the wheel the Hypersquare, a shape that’s less a rectangle and more like an oversized smartphone with rounded corners. Its form avoids brushing a driver’s legs, keeps displays in clear view, and hosts an array of thumb-accessible controls. Contoured grips and thumb holes allow multiple hand positions, improving comfort and freeing up cabin space—a thoughtful nod to ergonomics in an era of digital steering.
The Hypersquare also exploits one of steer-by-wire’s most powerful benefits: adaptive steering ratios. At motorway speeds, the wheel is less sensitive, making it easy to hold a line. At low speeds, you can rotate lock-to-lock with minimal effort, perfect for city parking. Comfort and sport modes let drivers tailor responsiveness, while torque corrections and electronic stability tweaks handle potholes, torque steer, or missed inputs.
Inside the Polygon concept, Peugeot pairs these innovations with the playful theatrics of gullwing doors and unusual seating. Yet beyond the show-car spectacle lies a serious preview: the next 208. Set to launch in 2027, the production 208 will debut Hypersquare on electric models before rolling it out across ICE variants and other Peugeot models. CEO Alain Favey likens it to Peugeot’s “Quattro”—a signature innovation that could define the brand for years to come.
On the road, the Hypersquare’s steer-by-wire system feels impressively natural. During testing on an E-2008 mule, sharp urban maneuvers initially felt odd, with the car’s rear seeming to float on casters. But after a few minutes, the responsiveness and lack of vibration made standard steering feel antiquated. On a high-speed test track, it excelled, providing accurate placement and clear tire feedback even through quick corners, cobbles, and blind crests. Steering ratios range from a brisk 5:1 at low speed to 21:1 in comfort mode on the straights, with sport mode dialing it in closer to a conventional 15:1 ratio.

There are minor quirks, mostly tied to the prototype’s mismatched chassis components, but Peugeot engineers are confident these will be resolved in production. And beyond practicality, the Hypersquare opens playful possibilities: disconnected from the road, it can serve as a controller for in-car games—melding driving and entertainment in a way few cars can.
In essence, the Polygon and Hypersquare represent Peugeot staking a claim in the driver-focused, tech-forward future. While other brands are experimenting with yokes or subtle drive-by-wire tweaks, Peugeot is committing fully, making its next supermini a testbed for steering’s next evolution. As Favey puts it, “We are playing a role in the future of cars. In 20 years, everyone will be offering this.”
The Peugeot Polygon may be a concept, but its Hypersquare wheel signals a revolution in how we’ll interact with cars—not just driving them, but feeling them, customizing them, and perhaps even playing them.
