Porsche has filed a patent for an electrically changeable exterior coating—described as "e-paper"—that can alter a vehicle's appearance to display racing stripes, drive-mode indicators such as Sport and Sport Plus, and an electric vehicle's state of charge.
The filing compares the technology to electrochromic glass systems, noting an electrical current applied to a coating layer can change appearance, and proposes applying the coating to aerodynamic elements including spoilers, splitters, vent slats and side blades.
Patent diagrams show examples of stripes appearing only when Sport Plus is selected, and Porsche states the change in exterior appearance can be used to identify properties or states of the vehicle to external viewers, with racing scenarios cited as an application.
The document is a patent filing and does not confirm production plans or timing for the "e-paper" coating.
