Mercedes unveils a prototype with photovoltaic “paint.” Vision Iconic demonstrates how a car can charge its battery by itself

At Shanghai Fashion Week, Mercedes-Benz unveiled the Vision Iconic — a prototype that for the first time integrates a photovoltaic (solar) solution directly into the bodywork. The manufacturer presents it as a testbed for functions and systems destined for future models, rather than a preview of a production version. The car’s design deliberately references classic Mercedes models: the 1930s era, the 300 SL Gullwing, the majestic W100 600 Pullman, and the W108 from the 1950s and 60s. It is a stylistic tribute to the “golden age” of motoring, combined with tomorrow’s technology.

“Paint” that generates electricity

The core innovation is a photovoltaic coating applied like paint. Mercedes says the PV modules are thinner than a human hair, weigh 50 g/m², and reach around 20% efficiency across roughly 11 m² — the size of an average SUV. A key feature is the protective layer: a nanoparticle-based paint that transmits 94% of sunlight to the cells. The system contains no silicon or rare-earth elements, is fully recyclable, and the coating color can be customized without compromising energy functionality.

The integrated PV modules generate electricity even when the car is off, charging the traction battery. Under ideal conditions, Mercedes highlights that the coating could supply enough energy for up to 12,000 km of driving per year. This is not a guarantee of solar range under all circumstances but demonstrates scalable potential given sufficient sunlight and active surface area.

From Stuttgart to Los Angeles: real-world scenarios

Mercedes illustrates the technology’s impact with practical examples. In Stuttgart, the car’s average daily travel is 52 km, 62% of which could be powered directly by solar energy to the high-voltage battery. In Los Angeles, thanks to more sunny days, daily driving could be 100% powered by PV energy under favorable conditions. The final results depend on climate, route, driving style, and how much of the car’s body can be converted into solar panels.

Mercedes is working to cover all exterior surfaces with photovoltaic coating, regardless of shape or angle. This would allow the PV layer to become an active energy surface across almost the entire body, rather than just a “flat panel.” Markus Schäfer, Mercedes-Benz Group CTO, says the Vision Iconic “embodies the vision of future mobility,” where the car’s material and coating contribute to its energy balance.

Neuromorphic electronics and drive-by-wire

The futuristic features go beyond solar power. The prototype uses neuromorphic computing to drastically reduce the energy consumption of data processing systems, enabling AI functions that are up to 90% more efficient. Vision Iconic also features a steer-by-wire system, removing the mechanical connection between the steering wheel and wheels. This allows more interior flexibility while maintaining precise control. Mercedes describes the automation level as enhanced point-to-point driving at Level 2, with future potential to support advanced functions like in-car streaming and reduced driver workload through autonomous systems.

To improve maneuverability, Vision Iconic has rear-axle steering, shortening the turning radius and easing city driving despite the car’s length. This architecture will be important if the entire body becomes an active energy surface, as it optimizes energy use even in urban traffic (less braking, fewer trajectory corrections).

Art Deco on wheels: “Zeppelin” interior

The cabin is a showcase of Art Deco design. The glass structure, called the “Zeppelin,” combines classic details with modern technology. The dashboard features four dials, one acting as an AI interface, and the four-spoke steering wheel merges traditional geometry with futuristic finishes. The brand logo resembles a glass orb, and opening the doors greets passengers with an analog animation.

As reported by Bild, Mercedes takes the concept further by presenting six fashion outfits inspired by the Vision Iconic’s aesthetic, completing the narrative of the car as a work of art, the driver as a curator of style.
