Citroën Electrifies the Iconic 2 CV with a Modern Concept

At the 2026 Paris Motor Show, the French automotive manufacturer Citroën introduced an innovative electric concept version of its celebrated 2 CV model, first revealed at the same event in 1948. This new iteration seeks to revive the small car's fundamental principles of light construction, economic accessibility, and day-to-day practicality, updating them for the electric age. Instead of merely replicating its historic form, Citroën is developing a novel electric vehicle for release by 2028, committed to making sustainable transportation attainable without compromising character.

The concept vehicle, measuring just 3.76 meters, is remarkably more compact than its predecessor, a distinct contrast to the prevailing trend of increasing vehicle sizes in the industry. It preserves the classic 2 CV's distinctive rounded contours, upright windshield, and gracefully sloping roofline, while incorporating modern design elements. Floating circular LED headlamps adorn the sculpted hood, 18-inch steel wheels offer a contemporary twist on the vintage design, and the vibrant Infra Red finish shimmers through various orange, yellow, and red hues under different lighting conditions. The manually operated retractable fabric roof, a nod to the original's open-air feel, successfully brings this feature into the electric vehicle era.

The interior of the Citroën 2 CV Concept demonstrates an equally imaginative approach. A cylindrical dashboard, a single-spoke steering wheel, streamlined controls, and an 8-inch square touchscreen displaying graphics by Belgian illustrator Jean-Luc Delvaux redefine the cabin's aesthetic. Essential driving data is presented via a Smart Vision display, strategically placed within the driver's line of sight. The cabin's playful design is further enhanced by yellow tartan upholstery paired with beige accents, drawing inspiration from the Bakelite components of earlier models, thereby creating a space that feels inviting and cheerful rather than overly technical. Practical features abound, including a removable front bench seat for outdoor use, a portable Radioën unit that doubles as a speaker, a 3D-printed storage basket crafted from wood and bio-based plastic in place of a central console, and fabric straps serving as door handles. Above, the roll-up fabric roof invites natural light, while a string of lights offers a festive ambiance, ensuring even short journeys are a delightful experience.

Beyond its nostalgic appeal, Citroën is spearheading a fresh vision for affordable electric mobility. The forthcoming European-built production model is projected to have a starting price of approximately €15,000. The concept's engineering prioritizes a low weight, near one tonne, reduced manufacturing complexity, and enhanced repairability through independently replaceable bumpers. Furthermore, a collaboration with Michelin is exploring digital tire-monitoring technology that utilizes vehicle data, eliminating the need for dedicated tire sensors. As Citroën CEO Xavier Chardon notes, the goal isn't to replicate the past but to reinvent it. The true test lies in whether the eventual production vehicle can maintain this delicate balance of simplicity, ingenuity, and distinct personality.

BIG's Innovative Design for Tirana's Fountain Plaza

Bjarke Ingels Group (BIG) has achieved recognition in the Fountain Plaza Tirana international design competition for its revolutionary proposal that elevates architectural form above a lush, park-like public domain in Albania's capital. This project harmonizes raised building volumes, a delicate translucent exterior, and a lattice of slender supports to fashion a structure that remains deeply connected to its natural surroundings. BIG's approach treats the entire site as a cohesive public environment, seamlessly blending a publicly accessible library, communal amenities, and a sheltered public auditorium within the existing green expanse. The design thoughtfully extends beyond the immediate building footprint, seeking to enhance pedestrian connectivity, expand green spaces, and integrate the surrounding infrastructure, including the adjacent canal, into a vibrant urban ecosystem.

The core concept of BIG's design for the Fountain Plaza Tirana is the complete fusion of the building and its landscape. A dense array of thin, cane-like columns lifts the entire structure off the ground, thereby liberating the area below for various public activities and ensuring unobstructed pedestrian flow. This intentional permeability was a key factor in the jury's commendation, who highlighted the design as offering one of the most generous park experiences among all entries. The upper levels are strategically recessed, facilitating the ingress of natural light into the covered auditorium and creating opportunities for additional landscaping. This integration of vegetation and public zones continues beneath and around the structure, which in turn offers essential shade and shelter. The building's ethereal facade, contrasting with its slender columns, contributes to a light and multi-layered aesthetic, further blurring the lines between built and natural environments.

An Integrated Public Realm for Tirana

BIG's winning design for Fountain Plaza Tirana masterfully intertwines public spaces, water elements, and the bustling urban fabric. By positioning a universally accessible library and integrated community resources at ground level, the design ensures that the area beneath the elevated structure evolves into a dynamic social hub rather than merely a transitional zone. The inclusion of a covered auditorium further enriches the public programming, establishing a dedicated venue for communal gatherings within the expansive, elevated edifice. This profound commitment to shared space extends its influence to the project's broader urban surroundings. The jury particularly noted BIG's foresight in exploring the potential for pedestrianizing the adjacent thoroughfare and extending the park towards neighboring districts. Such visionary initiatives reflect a holistic design philosophy that transcends the immediate confines of the building, transforming the competition into an unparalleled opportunity to re-imagine the symbiotic relationship between pedestrians, verdant landscapes, and the urban infrastructure. The jury specifically applauded the integration of the adjacent canal, recognizing its potential to function as an active and vital component of the design, thereby linking the waterway directly to the ecological and microclimatic characteristics of the site.

The conceptual framework behind Fountain Plaza Tirana revolves around creating an unbroken continuum between built forms and natural settings. The building itself is lifted by a dense arrangement of slender, vertical columns, akin to reeds, creating an open expanse beneath that invites public interaction and ensures seamless movement for pedestrians. This deliberate openness was particularly lauded by the competition jury, who praised the scheme for providing one of the most expansive and accessible park experiences among all submissions. The upper floors are strategically set back, allowing ample natural light to permeate the covered auditorium and providing space for lush planting. This integration means that vegetation and public zones extend fluidly both beneath and around the structure, which simultaneously offers much-needed shade and shelter from the elements. The facade's translucent quality, when juxtaposed with the delicate supporting columns, imbues the building with a light, airy, and multi-dimensional appearance, further enhancing its harmonious integration with the environment.

Fountain Plaza Tirana: A Model for Urban Connectivity

The Fountain Plaza Tirana project by Bjarke Ingels Group stands as a paradigm of modern urban design, focusing on the seamless connection between public life, natural elements, and the city. Its ground floor, housing an open-access library and various community facilities, is meticulously planned to be a vibrant social destination, transforming the space beneath the main structure from a mere passageway into an active communal hub. The addition of a covered auditorium beneath the elevated building further enhances its role as a public gathering place, suitable for a wide range of collective events. This emphasis on shared public spaces is also reflected in the project's thoughtful engagement with its wider urban context. The jury commended BIG's forward-thinking approach, which considered the pedestrianization of nearby traffic arteries and the expansion of the park into adjacent areas. These strategic interventions demonstrate a vision that goes beyond the immediate architectural footprint, utilizing the competition as a catalyst to redefine how people, green spaces, and surrounding infrastructure can interact and flourish. A standout feature highlighted by the jury was the proactive integration of the adjacent canal, transforming it into an active element within the design that connects the waterway to the site's environmental and microclimatic conditions, enhancing both ecological and recreational value.

At the heart of the Fountain Plaza Tirana design lies the fundamental principle that the architectural form and its natural surroundings should function as a single, indivisible entity. The structure is supported by an intricate array of slender, column-like elements, which elevate the building and create an expansive, permeable ground level dedicated to public use and pedestrian circulation. This exceptional permeability was a significant factor in the jury's decision, who lauded the project for offering an unparalleled park experience compared to other competition entries. The upper stories are carefully recessed, designed to maximize the penetration of natural light into the covered auditorium and to accommodate additional green spaces through integrated planting. The verdant landscaping and public areas extend seamlessly beneath and around the building, which in turn provides essential shade and shelter, fostering a comfortable microclimate. The building's facade, characterized by its transparency and lightness, stands in elegant contrast to the delicate supporting columns, contributing to an aesthetic that is both layered and visually understated, making the entire complex appear to float above the landscape.

Carsten Höller's Goggles: A Journey into Altered Perception

This article explores Carsten Höller's captivating art installation, the 'Upside-Down Goggles', which fundamentally alters visual perception. It delves into the historical context provided by psychologist George M. Stratton's pioneering work on inverted vision, highlighting the profound impact these devices have on our understanding of reality, movement, and the adaptive nature of human perception.

Challenge Your Senses: Experience Reality Anew

Carsten Höller's Artistic Disruption of Orientation

Artist Carsten Höller, known for his intriguing installations that challenge conventional perceptions, once likened dreams to "confusion machines." He finds fascination in phenomena that disrupt our usual sense of control, noting how dreams create convincingly real yet unstable environments where normal physical actions become impossible. Höller extends this exploration of uncertainty into his art through various interactive pieces, such as slides that induce vertigo, rotating beds, and wearable devices, all designed to interfere with our everyday experience of the world.

The Pioneering "Upside-Down Goggles": A Visual Inversion

Among Höller's notable creations are his 'Upside-Down Goggles', first unveiled in 1994. These unique spectacles invert the wearer's entire visual field, rendering familiar surroundings completely upside down. Simple tasks like navigating a room or reaching for an object suddenly demand heightened concentration and a recalibrated approach. While the physical space remains unchanged, the act of moving within it loses its inherent intuitiveness, forcing a re-evaluation of spatial relationships.

Historical Precedents: George M. Stratton's Visionary Experiments

The concept of inverted vision has historical roots, notably in the late 19th century work of American psychologist George M. Stratton. Intrigued by how our brains perceive an upright world despite inverted retinal images, Stratton developed an optical device that reversed his visual field. He meticulously documented his experiences, including an initial 21.5-hour trial over three days in 1896, followed by a more extensive 87-hour study in 1897. His observations, as he struggled to coordinate movement with his altered sight in his garden and village, revealed the profound impact on spatial understanding. Stratton's groundbreaking research established visual adaptation as a crucial area of psychological inquiry, suggesting that perception is an active process shaped by the dynamic interplay of sight, movement, and lived experience.

The Impact of Höller's Goggles on Perception and Movement

Höller notes that even a mere five minutes of wearing his goggles can initiate a subtle shift in perception. This experience intensifies dramatically once the wearer begins to move. Objects may appear to blend into one another, and distances become distorted, appearing either unexpectedly near or far. The visual inversion is just one aspect of the effect; physical movement profoundly alters perceived relationships, making the surrounding environment challenging to interpret.

Reconnecting Vision and Physical Experience

These experiences highlight the fundamental connection between vision and physical action. We seldom contemplate the unconscious coordination involved in judging distance, grasping a glass, or stepping around furniture. Such actions rely on a seamless integration of what we see and how we move. The goggles deliberately disrupt this coordination, transforming routine gestures into hesitant and uncertain ones. Furthermore, there's a distinction between merely adapting to a novel visual input and feeling genuinely comfortable within the distorted reality it presents.

Contrasting Experimental Approaches to Inverted Vision

While Stratton's experiments primarily focused on long-term adaptation to inverted vision, Höller's observations center on the initial minutes of wearing the device. During this short period, perception might begin to adjust, but movement remains profoundly unfamiliar. Wearers must operate within a world that, despite its recognizable details, no longer behaves as expected. Höller's goggles thus make the act of navigating an ordinary space an acutely uncertain endeavor. What typically goes unnoticed—the intricate coordination of sight, distance, and movement—becomes the central, captivating focus of his artwork.
