- Porsche patented body panels that can change color electronically.
- The system could add racing stripes in different drive modes.
- Future EVs might display battery charge through exterior color changes.
It’s a question that dates back decades. Do you option your fancy sports car with or without visual flourishes like rally or racing stripes? Once you choose, changing your mind isn’t exactly an easy task. Installing or removing stripes is a painstaking process on one’s own and can cost thousands when a professional does the work.
Porsche owners might not have to make that choice in the near future. A new patent would allow them to switch from stripes to no stripes with the push of a button.

According to the newly published patent application that was first spotted by Jalopnik, Porsche’s system would use an “actively controllable, optically variable coating” applied to exterior body panels. When voltage is applied, the coating changes appearance.
The company says the technology could rely on either so-called electronic paper or paramagnetic coatings, both of which can alter their color when electricity is introduced. This kind of tech already exists, but it’s not used in this fashion.
Plenty of automakers use it for glass panels which allows the occupant to make the glass appear transparent or opaque on command. The big change here is using it on a body panel instead. According to the patent, Porsche owners would see the “rally stripes” appear when the car goes into Sport mode. Additional accents could also light up around areas like the diffuser or the side blades behind the rear wheels.
An EV Battery Indicator Too
Porsche says the idea is partly cosmetic, but there is a functional side too. The company notes that racing stripes could help identify one car from another during competition, especially when multiple identical cars are on track at the same time. Porsche also believes the same coating could act as an exterior battery gauge on EVs.
Instead of opening an app or looking at the dashboard, owners could glance at the car and instantly know how much charge remains. A panel might glow green when the battery is nearly full, yellow when it is running low, and red when it is close to empty.
While there’s no way to know for sure if or when Porsche gives this idea the green light, it’s very much the kind of tech we see popping up more and more across the bleeding edge of the industry. Sooner or later, someone will probably put it into production. Here’s hoping Porsche makes it happen and lets other automakers license the tech.
