How does Peugeot’s revolutionary steering wheel work?

Peugeot is set to upend a century of driving habits with its Hypersquare steering wheel, an interface completely rethought around pleasure and precision.

Presented through the Polygon concept, this steering wheel is not just a change of shape: it’s a new way to drive a car. The Hypersquare operates using steer-by-wire technology, already proven in aeronautics. Here, no mechanical component connects the wheel to the wheels: each movement is sent as an electronic signal to the steering. This technological choice enables a quicker, more precise and, above all, fully adjustable response depending on driving conditions.

Maximum agility at low speeds

One of the major advantages of this solution is the variable steering ratio. In town, when parking or making a tight U-turn, the wheel now turns only 170° to each side, i.e. less than a full revolution. Gone are the wide rotations that required grabbing and releasing the wheel: everything is done with a simple wrist movement, without ever moving the hands. Maneuvers become instinctive, faster and noticeably less tiring.

At higher speeds, the Hypersquare adopts the opposite behavior: the steering becomes more progressive. A slight impulse is then enough to adjust the trajectory, offering a sensation of extreme agility and a feel close to the precision of a joystick. The driver gets exactly the response they expect, no more, no less.

A wheel designed for feel

Even without a steering column, Peugeot has taken care of the “road feedback.” The system filters out unwanted vibrations — potholes, cobblestones, irregularities — while retaining the essential information to anticipate grip or the condition of the road surface. A rare balance, aimed at making driving both more comfortable and clearer.

The Hypersquare also incorporates four circular controls at the corners of the wheel, accessible without lifting the hands. The whole is part of a deep evolution of the i-Cockpit, designed to reduce hand movements, improve concentration and make the car more intuitive.
