Peugeot has unveiled the Polygon Concept, a sub-4-meter compact demonstration vehicle showcasing technologies scheduled for production deployment from 2027. The concept introduces Hypersquare, a square-shaped steering control integrated with Steer-by-Wire technology, replacing the traditional circular steering wheel architecture used in automotive design for over a century.
The vehicle serves as a dynamic testing platform for next-generation cockpit systems, sustainable manufacturing approaches, and modular design strategies. Peugeot previewed the concept in Polygon City, a branded environment within the Fortnite gaming platform, before physical reveal.
Highlights
- Hypersquare steering control limits rotation to 170° in each direction (total 340°) versus three full rotations with conventional wheels
- Steer-by-Wire system eliminates mechanical linkage between steering input and front wheels, with production implementation targeted for 2027
- 31-inch equivalent windscreen display measures 24cm wide by 74cm high using Micro-LED projection technology
- Modular component design enables rapid configuration changes with interchangeable body panels, seats, and interior elements
Hypersquare and Steer-by-Wire Technology
Electronic Steering Architecture
The Hypersquare system represents Peugeot’s first application of fully electronic steering control. Steer-by-Wire technology, derived from aerospace applications, removes all mechanical connections between the steering input device and the vehicle’s front wheels.
The system operates through electronic signals transmitted from the Hypersquare control unit to actuators at the wheels. This architecture enables variable steering ratios that automatically adjust based on vehicle speed.
Low-speed operation characteristics:
- Maximum 170° rotation in each direction
- Reduced input required for parking maneuvers
- Elimination of hand repositioning during tight turns
High-speed operation characteristics:
- Smaller inputs produce proportional directional changes
- Enhanced precision for lane adjustments
- Filtered road feedback removes unwanted vibrations while maintaining essential tactile information
Control Pod Configuration
Four circular control pods are integrated at each corner of the Hypersquare unit. These pods provide access to vehicle functions without requiring hand movement from the steering surface. The ergonomic layout repositions primary vehicle controls within direct finger reach.
Advanced Display Systems
Windscreen Projection Technology
The Polygon Concept eliminates traditional dashboard displays. A Micro-LED panel positioned behind the Hypersquare unit projects all instrumentation data directly onto the windscreen surface.
Display specifications:
- Screen dimensions: 24cm width x 74cm height
- Equivalent size: 31-inch diagonal measurement
- Positioning: Direct driver sightline alignment
- Visibility: Exterior-visible when vehicle is stationary
Configurable Display Modes
The system offers three distinct operational modes:
Cruise Mode: Standard driving information display with balanced interior/exterior lighting synchronization
Fun Mode: Enhanced visual elements with dynamic animations coordinated between cabin and exterior lighting
Hyper Mode: Performance-focused display configuration with real-time vehicle dynamics data
A rotary dial controller with integrated LED screen manages mode selection and displays ambient information including time and temperature.
Exterior Lighting Architecture
Micro-LED Implementation
Peugeot’s signature three-claw light design transitions to a horizontal configuration using Micro-LED arrays. The front and rear lighting assemblies consist of multiple Micro-LED screens capable of displaying various graphic configurations.
The C-pillar integrates a dedicated Micro-LED display adjacent to the pop-up charging connector. This screen provides battery status information without requiring vehicle access.
Interior Space Optimization
Dashboard Reconfiguration
The elimination of traditional steering column components and the integration of Hypersquare technology enables complete dashboard redesign. The revised architecture increases available cabin volume for both front occupants.
Customizable storage solutions accommodate various items:
- Mobile devices
- Audio equipment
- Personal accessories
- Sports equipment including skateboards
Structural Design Changes
The Polygon Concept employs two butterfly-style doors replacing conventional four-door architecture. The windscreen extends forward and downward with B-pillar removal, increasing glazed surface area.
Seating Technology
The seat design combines 3D-printed shells with single-piece molded foam construction. Shell material consists of recycled PET plastic (R-PET) produced through large-scale additive manufacturing in collaboration with Spanish manufacturer Nagami.
Foam components, developed with Belgian company Sixinch, feature integrated protective coating eliminating separate fabric covering. The three-component seat assembly (shell, structure, foam) replaces traditional multi-piece construction.
Tire Technology Integration
Goodyear supplies custom tires featuring colored sidewalls and laser-engraved patterns. The tires incorporate SightLine intelligent monitoring technology, providing real-time data transmission to the cockpit display system.
SightLine capabilities:
- Tire pressure and temperature monitoring
- Road condition assessment
- Configuration recognition for component swapping
- Mode-specific data display integration
Sustainable Manufacturing Approach
Recycled Material Implementation
Interior lacquer incorporates components recovered from end-of-life tire processing. Cabin surfaces utilize forged textile manufactured from recycled seats sourced from deconstructed Peugeot vehicles.
Wheel covers use R-PET plastic in single-piece 3D-printed construction including integrated fastening systems.
Component Reduction Strategy
The concept demonstrates parts-count reduction compared to conventional vehicle architecture:
Seating: Three primary components versus dozens in traditional assemblies
Doors: Two butterfly doors replace four conventional units
Dashboard: Modular storage elements with tool-free replacement capability
Serviceable Design Philosophy
Multiple components enable rapid replacement without specialized tools:
- Seat foam modules (color and density variations)
- Hypersquare steering units (material and finish options)
- Wheel covers
- Dashboard storage elements
This approach extends vehicle lifecycle through configuration updates rather than complete replacement.
Configuration Examples
Peugeot demonstrates three distinct Polygon Concept variations:
Urban: Minimalist exterior treatment with refined surface finishes for metropolitan environments
Player: Performance-oriented visual elements with dynamic body detailing
Explorer: Elevated ride height with protective cladding and reinforced appearance
These configurations share core mechanical architecture while varying exterior panels, wheel designs, and interior trim selections.
Production Timeline
Steer-by-Wire technology and Hypersquare steering control are scheduled for production vehicle integration beginning in 2027. The Polygon Concept serves as a validation platform for systems planned for next-generation Peugeot models.
