The BMW X6 Vantablack show car at the 2019 Frankfurt Auto Show is finished in Vantablack VBx2 paint that abosrbs 99.965% of all light.
This makes the car (or anything painted in it) look two dimensional, meaning it can’t actually be used for a road legal vehicle. The paint is typically used for sculpture and architecture.
The paint is made up carbon nanotubes around 14 to 50 micrometers long, and 2020 nanometers wide. It’s about 5,000 times thinner than a human hair, and around a billion of them can fit in a square centimeter. Light hitting the surface is absorbed and turned into heat rather than reflected.
