New tech works like electrochromic glass, letting the car’s exterior shift appearance on demand.
Porsche is exploring a bold new direction in automotive design, and it’s closer to science than sci-fi. A recently published patent reveals the company is developing a special “electronic paper” coating that can change how a vehicle’s exterior looks at the push of a button.
The idea goes beyond simple styling tweaks. According to the filing, the system could display dynamic racing stripes that only appear under certain conditions—like when the driver switches into a performance-focused driving mode.
The technology works similarly to electrochromic glass already used across the Volkswagen Group lineup in panoramic roofs. By applying an electric current to a special layer, the material can shift its transparency or color. Porsche, however, wants to take that concept further—using it not for sun protection, but as a visual communication tool.
For example, classic racing stripes could automatically appear when Sport Plus mode is activated, giving the car a more aggressive look only when it’s being driven hard. The system could also display useful information, such as an electric vehicle’s battery charge level, directly on the body panels.
Porsche says this kind of visual feedback could make it easier for others to instantly recognize a car’s performance state or capabilities. The patent specifically highlights aerodynamic components—like spoilers, splitters, and air vents—that could visually stand out when the car is set to its sportiest configuration.
While the brand is clearly thinking about track applications, industry watchers believe the real appeal may lie elsewhere. For many owners, this could become a new form of personalization. If deployable spoilers and loud exhaust notes aren’t enough to turn heads, a set of glowing racing stripes appearing in a parking lot probably will.
